Colorado Targets Private Equity in Law Firms: What HB26-1421’s Fee-Sharing Ban Means

On June 3, 2026, Governor Jared Polis signed House Bill 26-1421, the Colorado Legal Practice Integrity and Fee-Sharing Prohibition Act. The bipartisan measure does something Colorado’s ethics rules already gesture at, but it does so with a statute, which includes a private right of action and a reach that extends beyond the state line.

For years, the prohibition on nonlawyer ownership of law firms and fee-sharing with nonlawyers has lived in Rule 5.4 of the Colorado Rules of Professional Conduct, enforced through the attorney-discipline system. HB26-1421 lifts that principle into the Colorado Revised Statutes (new Part 4 of Article 93, Title 13), adds civil remedies, and aims them squarely at the alternative business structures (“ABS”s) and management services organizations (“MSO”s) that outside capital, including private equity, litigation funders, and others have used to participate in the economics of legal services.

Here is what the new law does and who needs to pay attention:

The Core Prohibitions

In connection with providing legal services, a lawyer or law firm may not:

• Share legal fees or revenue with nonlawyers or alternative business structures. No portion of legal fees or revenue, whether gross or net, and no other financial benefit derived from legal services may flow, directly or indirectly and however labeled, to an ABS or a nonlawyer. The one carve-out is ordinary compensation: lawful wages, salaries, benefits, and discretionary bonuses paid to a firm’s nonlawyer employees for work done in the ordinary course.
• Contract with an alternative business structure on anything touching legal services. Financial, ownership, management, marketing, co-counsel, referral, and fee-allocation arrangements with an ABS are all off the table where they relate to providing legal services.
• Form an entity with a nonlawyer that provides legal services. If any of the entity’s activities consist of providing legal services, a lawyer cannot form it with a nonlawyer.
• Practice in a company a nonlawyer owns or controls. A lawyer may not practice in a for-profit professional company authorized to provide legal services if a nonlawyer holds any ownership interest or has the right to direct or control a lawyer’s professional judgment.

One question the fourth prohibition invites is whether it sweeps in corporate legal departments, since every in-house lawyer works for a company owned by nonlawyer shareholders. Under the new law, it does not. The ownership bar reaches only a professional company “authorized to provide legal services for profit,” meaning a client-facing law practice rather than an operating business that happens to employ counsel. The Act is scoped throughout to legal services provided to third parties, and its declared purpose is to prohibit nonlawyer ownership and fee-sharing “in the provision of legal services to third parties,” so a lawyer advising her own employer sits outside it. The drafting is not airtight (and somewhat confusing), however, as the statute’s definition of “law firm” expressly folds in the “employer of a lawyer who is directly employed as in-house counsel.” A literal reading could recast this as a nonlawyer-owned “law firm.” But every operative prohibition turns on the provision of legal services to others, so that reading appears baseless. Further, the Act separately preserves an employer’s right to collect statutory attorney-fee awards, confirming the in-house relationship was contemplated and left intact.

Additionally, the statute is a substance-over-form rule: how a compensation arrangement is characterized does not change whether the prohibition applies.

Definitions Built to Stop Workarounds

The reach of the law lives in its definitions, which are deliberately expansive:

• An “alternative business structure” is any entity, wherever organized or whatever it calls itself, that either economically participates in, provides, or controls legal services, or shares in the profits or a percentage of legal fees (directly or indirectly, with or without any control), and that is owned by, controlled by, or fee-sharing with one or more nonlawyers.
• “Economically participates in” is the anti-circumvention hook. It captures equity interests, profit- or revenue-sharing, options, warrants, convertible or contingent equity, phantom equity, and any other arrangement, “however structured or described,” that gives a nonlawyer a financial interest in legal fees, firm revenue, or firm profitability. A financial interest arising solely from owning or being assigned a claim is excluded, so long as the holder doesn’t direct or control a lawyer’s professional judgment.
• “Legal fee” is similarly broad, reaching contingent, flat, hourly, hybrid, and success fees; allocated portions of settlements and judgments; retainers; and revenue routed through affiliated entities, technology platforms, service providers, or fee-collection intermediaries.

Why HB26-1421 is Really About Private Equity in Law Firms

The Act speaks in the neutral language of “outside capital” and “nonlawyers,” but in practice it is aimed at one thing in particular: private equity. This is clear by the definition of “economically participates in,” which definition is the linchpin of the law.

Ordinary wages, salaries, benefits, and discretionary bonuses paid to a firm’s nonlawyer employees are expressly fine. Options, warrants, convertible or contingent equity, and phantom equity are not. None of those terms are common in statutory drafting; rather, they come from the vocabulary of deal-making and transactional and executive-compensation practice, where they describe ways to provide someone with the economic upside of ownership without a literal equity share. “Phantom equity” is a clearest tell. This phrase is not often written into a statute, so the legislature’s naming it signals that its goal is squarely focused on eliminating synthetic-ownership and profit-participation structures by name, before they can be relabeled.

The catch-all that follows, reaching any arrangement “however structured or described,” confirms the intent. In the law firm setting, the effect is to close the narrow gap between a permitted bonus and a prohibited equity interest: phantom units that track firm profitability are functionally an ownership stake, the very thing Rule 5.4 has always forbidden. This is the provision that has the teeth, and the rest of the prohibitions largely follow from it.

The MSO rule confirms the PE target. In states that still have Rule 5.4, the most common way investor capital reaches a firm’s economics is a management services organization that handles back-office functions and takes its fee as a percentage of firm revenue or profit. HB26-1421 permits the MSO but bans the percentage, collapsing the standard workaround while leaving genuine fixed-fee and hourly administrative support alone.

The litigation-funding safe harbor draws the same line from the opposite side. Lending against the proceeds of identified cases, capped at a multiple or an interest rate, is allowed; taking a share of the firm’s fees, revenue, or profits is not. That is precisely the boundary between traditional litigation finance and an equity-style stake in the practice itself.

What animates the model’s critics is the endpoint rather than any single deal. The worry is that the ABS structure lets private equity vertically integrate the machinery of mass-tort and class-action litigation, rolling up firms, lead-generation marketers, claim aggregators, and affiliated medical or administrative vendors into a single enterprise whose incentives run to investor returns rather than client outcomes. Proponents may counter that outside investment expands access to legal services and breaks the traditional firm’s monopoly on capital. That debate is far from settled; what HB26-1421 does is foreclose the investment side of it in Colorado and reaches beyond the state’s borders to do so.

Out-of-State Firms are Not Off the Hook

“Legal services” is defined by reference to a legal right “arising in whole or in part in Colorado,” regardless of where the lawyer or firm is located. The legislative declaration is explicit that Colorado intends to regulate the provision of legal services affecting Colorado clients wherever the provider sits. That extraterritorial framing is one of the most consequential, and most likely to be contested, features of the statute.

A practical wrinkle shows how wide that reach runs. The U.S. District Court for the District of Colorado does not require Colorado bar membership to join its bar; any attorney licensed and in good standing in another U.S. jurisdiction may be admitted, and the court does not use pro hac vice at all. A substantial number of out-of-state lawyers and firms therefore handle Colorado-connected federal matters without ever holding a Colorado license. The Act reaches them regardless because its trigger is a Colorado-arising legal right rather than the lawyer’s licensure. And because the only express federal carve-out is for administrative matters arising under federal law or before a federal agency, ordinary federal-court litigation is left uncovered. Whether Colorado can dictate the ownership structure of a firm whose only connection to the state is a case in federal court, admitted under that court’s own rules, might be a Supremacy Clause question and one distinct from the dormant Commerce Clause objections its extraterritorial reach already invites.

MSOs Survive, but Only on Fixed or Hourly Terms

The new law does not ban management services organizations. A firm can still pay an MSO for administrative, operational, financial, marketing, or management support. What it cannot do is tie that compensation to the legal economics: Payment to an MSO may not be contingent on, or calculated as a percentage of, legal fees, revenues, or profits, and may not be keyed to recoveries, settlements, judgment awards, or case outcomes. Flat-fee and hourly structures remain permissible; percentage-of-revenue and success-based structures do not.

Enforcement: A Private Right of Action with Real Consequences

This is where the statute departs sharply from the disciplinary model. Two categories of plaintiff can sue:

1. A person who received legal services alleged to violate the Act may recover economic damages equal to the legal fees they paid, plus injunctive and declaratory relief, plus reasonable attorney fees and costs.
2. Competitor firms. A law firm doing “substantial business in Colorado” (meaning more than 10% of its annual revenue comes from legal services for clients) that has suffered or may suffer lost revenue from another firm’s violation may seek injunctive or declaratory relief and disgorgement, but not economic damages. A competitor must first give written notice to the Attorney General and may proceed only if the AG has not filed its own action within 60 days.

On top of damages, a court that finds a violation must order the offending funds disgorged to the state treasurer for deposit in the general fund (offset by any economic damages awarded to a plaintiff). And any contract or agreement that violates the Act is void.

The Safe Harbors

The Act builds in several express carve-outs:

• Fixed-fee work for clearly defined legal services is permitted, provided the fee is a predetermined dollar amount, is not paid for referrals or lead purchases, is not contingent on outcome or recovery, is not primarily aimed at pursuing monetary damages, and is not bundled with any referral- or outcome-based compensation.
• Pledging future revenues, fees, or recoveries as loan collateral is allowed.
• Nonrecourse litigation funding tied to specific, identified representations is allowed, but only if the funding covers fees or expenses of identified matters (not client acquisition); the funder’s return is limited to a multiple or an interest rate rather than a share of fees, revenue, or profits; and the funder has no right to participate in firm economics beyond the proceeds of those specific matters.
• Federal administrative matters, nonprofit and access-to-justice organizations, and the Colorado Supreme Court’s authority over the practice of law are all expressly preserved.

Timing

The Act takes effect at 12:01 a.m. on the day after the 90-day post-adjournment period, which is August 12, 2026 given the May 13 sine die adjournment, unless a referendum petition is filed, in which case it would depend on the November 2026 election. It applies to conduct and to contracts and agreements entered into or renewed, on or after the effective date.

Notably, the law carries a sunset: It repeals on September 1, 2029, which positions the next several years as something of a trial run.

What to Watch

The statute is part of a broader national contest over whether outside capital can own or share in the upside of law firms. A handful of jurisdictions have moved the other way: Arizona, effective January 1, 2021, became the first state to eliminate Rule 5.4 altogether, and its Supreme Court now licenses alternative business structures in which a nonlawyer may hold an economic interest and even decision-making authority in a firm, precisely the arrangements HB26-1421 is built to bar. Colorado has now planted a flag firmly on the other side, adding private enforcement and extraterritorial reach that the ethics rules never carried.

Takeaways

Any firm with Colorado-touching matters and any investor or service provider with an economic stake in such a firm should review existing and contemplated arrangements before the effective date. The substance-over-form standard means relabeling a percentage arrangement as a “fee,” a “management charge,” or a platform cost will not solve the problem. MSO contracts tied to firm performance, equity-like incentives for nonlawyer partners or platforms, and funding deals structured around fee participation are the most exposed and should be restructured to fixed or hourly terms or to the law’s narrow funding safe harbor, well ahead of August.
