To justify an award of attorney fees under subsection (4), a trial court must make a finding that a claim "lacked substantial justification", i.e., was substantially frivolous, substantially groundless, or substantially vexatious, and must state its reason for the finding. In re Gomez, 728 P.2d 747 (Colo. App. 1986); In re Estate of Finkelstein, 817 P.2d 617 (Colo. App. 1991); Fowler Irrevocable Trust 1992-1 v. City of Boulder, 992 P.2d 1188 (Colo. App. 1999), aff'd in part and rev'd in part on other grounds, 17 P.3d 797 (Colo. 2001); Double Oak Constr., L.L.C. v. Cornerstone Dev. Int'l, L.L.C., 97 P.3d 140 (Colo. App. 2003).

"Substantially frivolous" or "substantially groundless" are no more demanding standards than "groundless" or "frivolous". In re Application of Talco, Ltd., 769 P.2d 468 (Colo. 1989); Little v. Fellman, 837 P.2d 197 (Colo. App. 1991).

The "no rational argument" test of W. Realty (679 P.2d 1063 (Colo. 1984)) will be followed in determining whether the standard has been met. Little v. Fellman, 837 P.2d 197 (Colo. App. 1991).

A vexatious claim is one brought or maintained in bad faith to annoy or harass. A vexatious claim includes conduct that is arbitrary, stubbornly litigious, or disrespectful of truth. Bockar v. Patterson, 899 P.2d 233 (Colo. App. 1994).

The exclusion of an expert's testimony due to lack of reliability does not subject a party to attorney fees for a groundless claim if the party reasonably relied on the expert; courts must allow parties to reasonably rely on their experts without fear of punishment for the experts' errors in judgment. In re Water Rights of Park County Sportsmen's Ranch, 105 P.3d 595 (Colo. 2005).

Aquifer storage and augmentation claims based on the natural percolation of irrigation run-off and precipitation are frivolous under § 37-92-103, because the water has not been placed in the aquifer by other than natural means. In re Water Rights of Park County Sportsmen's Ranch, 105 P.3d 595 (Colo. 2005).

The purpose of awarding attorney fees is to deter egregious conduct, and not to discourage legal theories that, while having no support in case law, nevertheless may be persuasive because of the unique character of the case. Wood Bros. Homes, Inc. v. Howard, 862 P.2d 925 (Colo. 1993); Bd. of County Comm'rs v. Colo., 888 P.2d 352 (Colo. App. 1994).

When a party consistently ignored the court's admonition to not relitigate settled matters, the court was justified in finding that the party's attorney was being stubbornly litigious and the action thus lacked substantial justification. Spring Creek Ranchers Ass'n v. McNichols, 165 P.3d 244 (Colo. 2007).

Trial court may determine action was "brought or defended" in a substantially groundless manner even if dismissed on the morning of trial before the trial actually commences. Engel v. Engel, 902 P.2d 442 (Colo. App. 1995).

Claims involving novel questions of law for which no determinative authority existed at time complaint was filed were not frivolous, groundless, or vexatious. Montoya by Montoya v. Bebensee, 761 P.2d 285 (Colo. App. 1988); Colo. Supply Co., Inc. v. Stewart, 797 P.2d 1303 (Colo. App. 1990); Bd. of County Comm'rs v. Colo., 888 P.2d 352 (Colo. App. 1994); Fowler Irrevocable Trust 1992-1 v. City of Boulder, 992 P.2d 1188 (Colo. App. 1999), aff'd in part and rev'd in part on other grounds, 17 P.3d 797 (Colo. 2001).

Trial court erred in awarding attorney fees where municipality's defense to takings claim involved a novel question of law and municipality's conduct presented factual issues upon which reasonable triers of fact might have drawn differing inferences. The fact that the municipality did not prevail in its assertions did not make them frivolous. Fowler Irrevocable Trust 1992-1 v. City of Boulder, 992 P.2d 1188 (Colo. App. 1999), aff'd in part and rev'd in part on other grounds, 17 P.3d 797 (Colo. 2001).

Trial court erred in awarding attorney fees where plaintiff's claims were based largely upon federal case law and involved novel questions of law upon which there was no determinative law in this state and where the evidence presented by the plaintiff arguably supported the plaintiff's claims. Kemp v. State Bd. of Agric., 790 P.2d 870 (Colo. App. 1989), cert. denied, 501 U.S. 1205, 111 S. Ct. 2798, 115 L. Ed.2d 972 (1990); Pedlow v. Stamp, 819 P.2d 1110 (Colo. App. 1991).

Issue of what constitutes receipt of a demand notice under § 7-113-209 (2) was a question of first impression; therefore the plaintiff's action was not "frivolous and without merit". M Life Ins. Co. v. S & W, 962 P.2d 335 (Colo. App. 1998).

A good faith presentation of a legal theory which is arguably meritorious is sufficient to avoid an award of attorney fees. SaBell's, Inc. v. City of Golden, 832 P.2d 974 (Colo. App. 1991), cert. denied, 846 P.2d 189 (Colo. 1993).

In a condemnation action, good faith negotiations do not necessarily require the condemning authority to increase its offer whenever the land owner makes a counteroffer. Therefore, plaintiff failed to show bad faith and vexatious conduct on the part of the defendant and was not entitled to an award of fees under this section. City of Holyoke v. Schlachter Farms R.L.L.P., 22 P.3d 960 (Colo. App. 2001).

To the extent the provisions of subsection (7) are in conflict with the provisions of § 13-17-201 concerning a good faith tort action that is dismissed under C.R.C.P. 12(b), mandatory attorney fees award provision of § 13-17-201 controls as it is specific to such action and was enacted later in time than this section. Houdek v. Mobil Oil Corp., 879 P.2d 417 (Colo. App. 1994).

A party seeking attorney fees bears the burden of proving, by a preponderance of the evidence, his entitlement to the award. Bd. of County Comm'rs v. Auslaender, 745 P.2d 999 (Colo. 1987); Little v. Fellman, 837 P.2d 197 (Colo. App. 1991); Am. Water Dev., Inc. v. City of Alamosa, 874 P.2d 352 (Colo. 1994); City of Holyoke v. Schlachter Farms R.L.L.P., 22 P.3d 960 (Colo. App. 2001).

Award of attorney fees must be made after trial court determines that all factors prove by a preponderance of the evidence that a defense was frivolous or groundless. Marinez v. Indus. Comm'n, 746 P.2d 552 (Colo. 1987).

In deciding whether to award attorney fees, a court must consider the factors set forth in § 13-117-103 (1). In re Aldrich, 945 P.2d 1370 (Colo. 1997); Remote Switch Sys., Inc. v. Delangis, 126 P.3d 269 (Colo. App. 2005).

In deciding whether to award attorney fees, a court must consider the factors set forth in § 13-17-103 (1). In re Aldrich, 945 P.2d 1370 (Colo. 1997).

When awarding attorney fees, a court must make findings explaining why a party's conduct was unjustified and discussing the means by which the court determined the amount of the award. Conclusory statements that a claim is frivolous, groundless, or vexatious are insufficient. In re Aldrich, 945 P.2d 1370 (Colo. 1997).

Award of attorney fees discretionary with trial court, and its decision will not be disturbed on appeal if supported by the evidence. Weber v. Wallace, 789 P.2d 427 (Colo. App. 1989); Lobato v. Taylor, 13 P.3d 821 (Colo. App. 2000), rev'd on other grounds, 71 P.3d 938 (Colo. 2002); Remote Switch Sys., Inc. v. Delangis, 126 P.3d 269 (Colo. App. 2005).

Award upheld where evidence presented to trial court with respect to father's defense against motion to change custody included findings that the mother had misled expert witnesses, that such witnesses had failed to investigate the child's circumstances with the father, that the mother had not properly assisted the child to recover from the impact of the dissolution, and that she had a scheme for obtaining custody of the child which involved actions not in the best interest of the child. Weber v. Wallace, 789 P.2d 427 (Colo. App. 1989).

Award upheld where there was record support for the trial court's determination that plaintiff's silence or refusal to properly clarify and communicate its position was "without substantial justification" and needlessly caused defendant to incur attorney fees. Front Range Home Enhancements, Inc. v. Stowell, 172 P.3d 973 (Colo. App. 2007).

Whether to award attorneys fees under this section is a matter ultimately committed to the discretion of the trial court. City of Holyoke v. Schlachter Farms R.L.L.P., 22 P.3d 960 (Colo. App. 2001).

Trial court did not abuse its discretion in denying award of attorney fees where claims made by the county did not lack substantial justification in law or in fact and were based on a rational legal argument. Bd. of County Comm'rs v. Colo., 888 P.2d 352 (Colo. App. 1994).

Findings of trial court that the plaintiff bank's claims of fraud were not groundless or frivolous were supported by the record, and the trial court did not abuse its discretion in denying the motion for sanctions. First Interstate Bank v. Berenbaum, 872 P.2d 1297 (Colo. App. 1993); Fowler Irrevocable Trust 1992-1 v. City of Boulder, 992 P.2d 1188 (Colo. App. 1999), aff'd in part and rev'd in part on other grounds, 17 P.3d 797 (Colo. 2001).

Findings of trial court that issues had been "fairly and vigorously litigated", together with record demonstrating at least some evidence to support the challenged defenses, supported trial court's denial of motion for sanctions under this section. Webster v. Boone, 992 P.2d 1183 (Colo. App. 1999).

The plaintiff's unsuccessful claim that it was not time barred from filing a claim relied on language from the statutes as well as prior cases, and the trial court considered and denied the defendant's motion for summary judgment three times before trial. Therefore, the trial court did not abuse its discretion in denying defendant attorney fees. Pat's Constr. Serv., Inc. v. Ins. Co. of the W., 141 P.3d 885 (Colo. App. 2005).

Plaintiff's action was not substantially frivolous, and the record provided support for trial court's implicit determination that the action was not maintained in bad faith, therefore, the trial court's order denying attorney fees was upheld. Berenergy Corp. v. Zab, Inc., 94 P.3d 1232 (Colo. App. 2004), aff'd on other grounds, 136 P.3d 252 (Colo. 2006).

The party requesting attorney fees under this section must prove by a preponderance of the evidence that the claim was without substantial justification. Bd. of Comm'rs, County of Boulder v. Eason, 976 P.2d 271 (Colo. App. 1998); Remote Switch Sys., Inc. v. Delangis, 126 P.3d 269 (Colo. App. 2005).

App. 1995); Bd. of Comm'rs, County of Boulder v. Eason, 976 P.2d 271 (Colo. App. 1998); Fowler Irrevocable Trust 1992-1 v. City of Boulder, 992 P.2d 1188 (Colo. App. 1999), aff'd in part and rev'd in part on other grounds, 17 P.3d 797 (Colo. 2001).

If a trial court's award of attorney fees is supported by the evidence, it will not be disturbed on review. Lyons v. Teamsters Local Union No. 961, 903 P.2d 1214 (Colo. App. 1995); Bd. of Comm'rs, County of Boulder v. Eason, 976 P.2d 271 (Colo. App. 1998); In re Eggert, 53 P.3d 794 (Colo. App. 2002).

Trial court finding that union pursued its claims "because [union president] agreed to testify", that there was "animosity" between the parties, and that the union's claims were "vexatious" was sufficient to award attorney fees. Lyons v. Teamsters Local Union No. 961, 903 P.2d 1214 (Colo. App. 1995).

An award of attorney fees is supported by the record when the attorneys reviewed their records and testified, subject to cross examination, that the claimed allocations of time were fair and reasonable. Farmers Reservoir & Irrigation Co. v. City of Golden, 113 P.3d 119 (Colo. 2005).

Trial court's award of attorney fees cannot stand where the court failed to hold an evidentiary hearing after a party made a claim for attorney fees and a hearing was requested, because a determination of entitlement to attorney fees cannot be made without adequate findings of fact and conclusions of law. Rogers v. Westerman Farm Co., 986 P.2d 967 (Colo. App. 1998), rev'd on other grounds, 29 P.3d 887 (Colo. 2001).

The court "shall" assess attorney fees if a claim lacks substantial justification. Montrose Valley Funeral Home v. Crippin, 835 P.2d 596 (Colo. App. 1992).

A trial court has the discretion to limit its award based on a finding that a party did not take all reasonable measures to extricate himself from a frivolous or groundless lawsuit at the earliest possible time. Ruffing v. Lincicome, 737 P.2d 440 (Colo. App. 1987).

Victim of a frivolous lawsuit has a duty to mitigate attorney fees incurred in defending the lawsuit by taking reasonable measures to extricate himself or herself from the lawsuit at the earliest possible time. Consequently, trial court should not have awarded attorney fees incurred in pursuing defendant's counterclaims after plaintiff dismissed its original complaint against defendants. Boulder County Bd. of County Comm'rs v. Kraft Bldg. Contractors, 122 P.3d 1019 (Colo. App. 2005).

Award of attorney fees and costs held excessive where court found that use of two attorneys was justifiable but that the trial court had awarded fees based on hours in excess of those reported in their affidavits and where court had awarded costs for depositions taken for ordinary discovery purposes rather than perpetuation of testimony. Weber v. Wallace, 789 P.2d 427 (Colo. App. 1989); Schmidt Const. Co. v. Becker-Johnson Corp., 817 P.2d 625 (Colo. App. 1991).

Trial court properly concluded that claim lacked substantial justification where court's detailed findings established that it considered the factors set forth in this section and § 13-17-103, and where court found the constitution, statutes, and case law clearly established the claims lacked "any legal foundation", that a good faith argument had not been advanced, and that the same arguments had been advanced and rejected in prior case. City of Littleton v. State, 832 P.2d 985 (Colo. App. 1991).

Award of attorney fees to the plaintiff was appropriate where the court found that the defense employed by the defendant lacked substantial merit and was used to delay and harass the plaintiff. Metro Nat. Bank v. Parker, 773 P.2d 633 (Colo. App. 1989).

Plaintiff's argument was not frivolous where she alleged the existence of an agency relationship based on a business relationship between the defendant, who was a private mortgage investor, and certain mortgage brokers. However, the argument was groundless where the only evidence of the agency was a number of similar transactions between the defendant and the brokers. Nienke v. Naiman Group, Ltd., 857 P.2d 446 (Colo. App. 1992).

Plaintiff's argument that her loan was a consumer loan was frivolous where a consumer loan must be incurred for a personal debt and the loan was incurred to pay taxes and expenses on an auto repair garage. Plaintiff's argument that the loan was personal because it was necessary to preserve the business for her son lacked a rational basis. Nienke v. Naiman Group, Ltd., 857 P.2d 446 (Colo. App. 1992).

Award of attorney fees proper where defendant has opportunity to challenge reasonableness of the amount of award. Trial court may not base award on affidavit submitted after trial. Kinsey v. Preeson, 746 P.2d 542 (Colo. 1987).

Probate court order that administrative expenses and attorney fees be paid from petitioner's distributive share upheld. The court so held because of petitioner's "relentless pursuit" of the same issues in three separate trial courts and in three appeals to this court. In re Estate of Leslie, 886 P.2d 284 (Colo. App. 1994).

Award of attorney fees based upon a groundless claim was appropriate where there was a lack of credible evidence presented on the essential issues of damages in negligent misrepresentation claim. Harrison v. Smith, 821 P.2d 832 (Colo. App. 1991).

Award of attorney fees appropriate where trial court properly determined that counterclaim for deficiency under a foreclosure lacked substantial justification because a review of the plain language of the contract would have revealed lack of support for the claim. Bernhardt v. Hemphill, 878 P.2d 107 (Colo. App. 1994).

Record supported trial court's award of attorney fees where the court found the defenses were substantially frivolous, groundless, and vexatious, that certain defenses were interposed for the sole purposes of delay, harassment, and to cause plaintiffs to incur legal expenses, and where defendant, even when proceeding without an attorney, clearly knew or should have known that the defenses asserted were substantially frivolous, groundless, or vexatious. Behr v. Burge, 940 P.2d 1084 (Colo. App. 1996).

Colorado Governmental Immunity Act does not shield public entities from an award for attorney fees for the filing of a frivolous claim by such entities. Colo. City Metro. Dist. v. Graber & Son's, Inc., 897 P.2d 874 (Colo. App. 1995).

County attorney is entitled to absolute immunity when filing guardianship petitions. It is illogical that an attorney could be immune from suit if brought separately under 42 U.S.C. § 1983, but not immune when fees are required in the same action under this section. In re Matter of Stepanek, 924 P.2d 1142 (Colo. App. 1996), aff'd, 940 P.2d 364 (Colo. 1997).

The constitution, statutes, and case law clearly establish that the City of Littleton's claims lacked any legal foundation, therefore, the trial court did not err in finding that the City had not advanced a good faith argument. City of Littleton v. State, 832 P.2d 985 (Colo. App. 1991).

Where city discovered mining waste on property during eminent domain proceeding but failed to disclose the presence of the waste or the potential remediation cost, court did not abuse discretion by finding bad faith and awarding respondent attorney fees incurred after city learned of the mining waste. City of Black Hawk v. Ficke, __ P.3d __ (Colo. App. 2008).

The denial of an award of attorney fees may be grounded upon the evidence admitted at trial upon the merits absent a specific request by one of the parties for the opportunity to present further evidence on the issue. No fees may be awarded, however, without providing the party against whom such an award is sought an opportunity to present such further evidence upon the issue as such party desires. Christian v. Westmoreland, 809 P.2d 1105 (Colo. App. 1991).

Award of attorney fees is not authorized unless the claim or defense was substantially frivolous, substantially groundless, or substantially vexatious. Although this restriction is not explicitly provided for in the statute, the title, purpose, and subsequent provisions of the statute indicate the intent that it apply only to frivolous, groundless, or vexatious actions. Shaw v. Baesemann, 773 P.2d 609 (Colo. App. 1988).

Arbitrary, vexatious, abusive, or stubbornly litigious conduct by a pro se litigant may serve as the basis for awarding attorney fees although the action or defense is not itself frivolous or groundless. Bockar v. Patterson, 899 P.2d 233 (Colo. App. 1994).

Filing of certificate of review does not preclude an attorney fee award for a vexatious claim. Mitchell v. Ryder, 104 P.3d 316 (Colo. App. 2004).

The prevailing party for purposes of awarding attorney fees when a claim exists for a violation of a contractual obligation is the party in whose favor the decision or verdict on liability is rendered. Travers v. Rainey, 888 P.2d 372 (Colo. App. 1994).

Trial court erred in awarding fees against surety for assertion of its claim that bonds were void where such contention was a good faith presentation of a legal theory which was arguably meritorious. SaBell's, Inc. v. City of Golden, 832 P.2d 974 (Colo. App. 1991), cert. denied, 846 P.2d 189 (Colo. 1993).

Pro se litigants are entitled to protection of subsection (6) unless trial court makes an express finding that such litigants knew or reasonably should have known that their claims lacked substantial justification. Failure to respond to a motion for fees does not obviate the need for such a finding. Artes-Roy v. Lyman, 833 P.2d 62 (Colo. App. 1992).

A party who successfully seeks summary judgment is not necessarily entitled to attorney fees. Little v. Fellman, 837 P.2d 197 (Colo. App. 1991).

Award of attorney fees is appropriate after the trial court renders a decision on the merits of the case. Forness v. Blum, 796 P.2d 496 (Colo. App. 1990).

Fees may be awarded even when the case is dismissed shortly before trial. Bilawsky v. Faseehudin, 916 P.2d 586 (Colo. App. 1995).

Fees may be awarded even when the trial court lacks subject matter jurisdiction. Here, the plaintiff not only lacked standing but also persisted in pursuing the claim despite knowing that it lacked admissible evidence to support the claim. Consumer Crusade, Inc. v. Clarion Mortgage Capital, Inc., 197 P.3d 285 (Colo. App. 2008).

Section effective in civil action commenced prior to effective date. Though dissolution of marriage proceeding was filed prior to effective date of this section, a subsequent motion to change custody of a child filed after such date which raised separate and distinct issues will be interpreted as a new civil action for the purposes of implementing the legislative intent of this section, and an award of attorney fees for costs incurred in defending the motion is proper. Weber v. Wallace, 789 P.2d 427 (Colo. App. 1989).

Section effective in any "part" of a civil action, including garnishment proceedings. Anderson Boneless Beef, Inc. v. Sunshine Health Care Ctr., Inc., 878 P.2d 98 (Colo. App. 1994).

Court should allocate sanctions between attorney and client according to their relative degrees of responsibility. Where attorney accepted "full responsibility" for decision to proceed with second writ of garnishment, after hearing on first such writ established the absence of a legal basis to do so, award against party jointly with attorney was erroneous. Anderson Boneless Beef, Inc. v. Sunshine Health Care Ctr., Inc., 878 P.2d 98 (Colo. App. 1994).

A principal may be liable for attorney fees based on its agent's litigation of a frivolous claim pursuant to the express terms of a contract. In re Water Rights of Park County Sportsmen's Ranch, 105 P.3d 595 (Colo. 2005).

Award of attorney fees was proper where party's attorney was on notice that garnishee did not hold any property of judgment debtor, although clerical error had made it appear so in a prior attempt to garnish the same account. Anderson Boneless Beef, Inc. v. Sunshine Health Care Ctr., Inc., 878 P.2d 98 (Colo. App. 1994).

Award of attorney fees improper where rational argument in support of the contention that exemplary damages may be awarded for bad faith breach of contract was made. William H. White Co. v. B&A Mfg. Co., 794 P.2d 1099 (Colo. App. 1990).

Where plaintiffs' counsel offered substantial legal arguments in favor of application of "discovery rule" to overcome statutory limitation of claims of sexual abuse of minors and where some of defendant's alleged acts of abuse occurred within the applicable limitation period, award of fees improper. Cassidy v. Smith, 817 P.2d 555 (Colo. App. 1991).

Award of attorney fees improper in abuse of process action where plaintiffs were not represented by an attorney and trial court did not make a finding that the plaintiffs knew or reasonably should have known that filing of the suit lacked substantial justification. Artes-Roy v. Lyman, 833 P.2d 62 (Colo. App. 1992).

Where defendant made rational arguments on the law in support of its position, trial court noted that legal issue was one of first impression in Colorado, and defendant was able to cite legal authority from other jurisdictions in support of its position, award of attorney fees was improper. Eurpac Serv., Inc. v. Republic Acceptance Corp., 37 P.3d 447 (Colo. App. 2000).

Award of attorney fees incurred in pursuing motions for sanctions improper where the defense to the motions, while ultimately unsuccessful, had a rational basis in fact and law and did not lack substantial justification. Boulder County Bd. of County Comm'rs v. Kraft Bldg. Contractors, 122 P.3d 1019 (Colo. App. 2005).

Award of attorney fees was an abuse of the trial court's discretion where the plaintiff's issue was one of first impression in Colorado, the plaintiff made a legitimate and reasoned attempt to extend the law, and the plaintiff presented some credible evidence to support her argument, even though the trial court found it was not sufficient to establish a prima facie case. Nienke v. Naiman Group, Ltd., 857 P.2d 446 (Colo. App. 1992).

An award of attorney fees under this section cannot be held to be confessed by failure to respond to a motion pursuant to C.R.C.P. 121. Artes-Roy v. Lyman, 833 P.2d 62 (Colo. App. 1992).

Trial court is not duty-bound to conduct a separate hearing on the issue of attorney fees before it may deny a request therefor. Hunter v. Colo. Mountain Jr. College, 804 P.2d 277 (Colo. App. 1990).

This section does not require redundant hearings. It simply prohibits a trial court from awarding attorney fees in the absence of a hearing, if requested, and detailed findings of fact. Padilla v. Ghuman, 183 P.3d 653 (Colo. App. 2007).

Active relitigation of settled issue that was clearly the law of the case is presumed to be frivolous and, thus, plaintiffs were entitled to attorney fees for frivolous second appeal of statute of limitations issue. Howard v. Wood Bros. Homes, Inc., 835 P.2d 556 (Colo. App. 1992).

When fees are awarded, the court is required to make evidentiary findings and must provide the opportunity for a hearing. Pedlow v. Stamp, 776 P.2d 382 (Colo. 1989); Little v. Fellman, 837 P.2d 197 (Colo. App. 1991).

If plaintiff's only reference to attorney fees is in the prayer, he or she has not alleged a claim for such fees under § 13-17-101. At most, the language provides notice that such fees may be requested. Township Homeowners Ass'n v. Arapahoe Roofing, 844 P.2d 1316 (Colo. App. 1992).

The trial court did not abuse its discretion in finding that residents' claims against a charter city were frivolous and in awarding attorney fees to the city. The trial court properly awarded attorney fees for a frivolous action where residents had no basis for a claim that the charter city's method for appointing municipal judges violated the state constitution and state statutes and no basis for a claim that the charter city violated state statutes in adopting ordinances that were of purely local concern. Artes-Roy v. City of Aspen, 856 P.2d 823 (Colo. 1993).

Trial court did not err in failing to apportion some of the fault to the attorney's clients where motion requested that sanctions be imposed only against the attorney, the attorney raised the defense that his clients should bear some of the responsibility for the plaintiffs' attorney fees, and the court implicitly rejected this argument by concluding that the attorney should be held fully accountable for his decision to ignore his obligations to opposing counsel. Parker v. Davis, 888 P.2d 324 (Colo. App. 1994).

A party is not automatically entitled to recover the expenses incurred in successfully pursuing a motion for sanctions since such fees may be awarded only if the trial court determines that the defense to the motion lacked substantial justification; however, the need for any further proof on that issue was dispensed with by defendant's judicial admissions. Parker v. Davis, 888 P.2d 324 (Colo. App. 1994).

To have standing to appeal an award of attorney fees only against a party's attorney, the attorney must file a separate appeal or be added as an appellant to the party's appeal. Anglum v. USAA Cas. Ins. Co., 166 P.3d 191 (Colo. App. 2007).

The absence of a cash outlay is insufficient cause for denying fees to an attorney simply because there has been self-representation. Reversing such an award would frustrate the intent of the general assembly in enacting this law to address the problem of increasing litigation which burdens the judicial system and interferes with the effective administration of justice and would reward plaintiffs who have filed frivolous or groundless actions. Zick v. Krob, 872 P.2d 1290 (Colo. App. 1993).

It is not appropriate for a court to award a grant of attorney fees to a pro se litigant. While there is an exception for pro se litigants who are attorneys under the appropriate circumstances, a pro se litigant who is not a licensed attorney has no "attorney fees". Smith v. Furlong, 976 P.2d 889 (Colo. App. 1999).

A pro se attorney litigant is not necessarily precluded from an attorney fee award under either this section or C.R.C.P. 107 (d)(2) in a contempt proceeding. Thus, a pro se attorney litigant may be entitled to attorney fees in a contempt proceeding if the trial court determines that an opposing party's conduct meets the requirements of the statutes in this part 1. Wimmershoff v. Finger, 74 P.3d 529 (Colo. App. 2003).

A pro se attorney may recover attorney fees. Giguere v. SJS Family Enters., 155 P.3d 462 (Colo. App. 2006).

The court is required to award attorney fees only if it finds that an attorney or party brought or defended an action that lacked substantial justification. United Guar. Residential Ins. Co. v. Dimmick, 916 P.2d 638 (Colo. App. 1996).

Absent a finding that the defense to a motion for fees lacks substantial justification, fees and costs may not be awarded for challenging that defense. Foxley v. Foxley, 939 P.2d 455 (Colo. App. 1996); Boulder County Bd. of County Comm'rs v. Kraft Bldg. Contractors, 122 P.3d 1019 (Colo. App. 2005).

To the extent § 13-17-101 et seq. is inconsistent with the procedural safe-harbor provisions of Fed. R. Civ. P. 11, it is preempted. McCoy v. West, 965 F. Supp. 34 (D. Colo. 1997).

This section is preempted in a § 1983 claim brought in state court. A claim brought pursuant to 42 U.S.C. § 1983 in state court is governed by the federal standards contained in 42 U.S.C. § 1988. State v. Golden's Concrete Co., 962 P.2d 919 (Colo. 1998).

Where plaintiff seeks attorney fees under this section and 42 U.S.C. § 1983 in a declaratory judgment action the trial court's findings of due process violations as a matter of fact and as a matter of law are an insufficient basis to trigger a 42 U.S.C. § 1988 award of fees because the 42 U.S.C. § 1983 claim was not properly raised or litigated during the declaratory judgment action. Bd. of Comm'rs, County of Boulder v. Eason, 976 P.2d 271 (Colo. App. 1998).

If a frivolous lawsuit includes both state law claims heard in state court proceedings and federal claims removed for federal court proceedings, a state court may award attorney fees incurred in producing work product for the federal court proceedings only to the extent that the work product was also used in the state court proceedings. Boulder County Bd. of County Comm'rs v. Kraft Bldg. Contractors, 122 P.3d 1019 (Colo. App. 2005).

Lack of an express grant of authority in the Colorado Rules for Magistrates to award attorney fees on review does not divest or otherwise curtail the district court's already existing authority to make such an award under this section. In re Naekel, 181 P.3d 1177 (Colo. App. 2008).
