What is a management services organization (MSO)?

The short answer

A management services organization is a company that contracts with a professional practice to provide everything the practice needs that is not the profession itself: administration, operations, finance, marketing, technology, human resources, facilities. The professionals keep doing the professional work. The MSO runs the business around it.

The model started in medicine, where physician practices used MSOs to consolidate billing, staffing, and back-office functions without transferring ownership of the medical practice to non-physicians. It has since spread to dentistry, veterinary medicine, accounting, and law. The reason is the same in each field: the professional services company usually cannot be owned by outsiders, but the business functions around it can be organized however the market finds efficient.

What an MSO does, and what it does not

A well-drawn MSO arrangement has a bright line through the middle of it.

On the MSO side: bookkeeping and billing operations, vendor and facilities management, staffing support, marketing execution, intake and workflow systems, technology and software, data and reporting.

On the practice side, and nowhere else: professional judgment. Who to represent, what strategy to pursue, what to charge, whether to settle, and every decision that belongs to the professional and the client. An MSO that starts making those calls is no longer providing business services. It is running the practice, which is the thing the law is designed to prevent.

Why law firms use them

Running a modern law firm means operating a technology company, a marketing department, a billing operation, and a customer service organization at the same time as practicing law. Most firm owners did not train for any of that, and at small and mid-size firms there is rarely enough work to justify a full-time hire in each function.

An MSO consolidates those functions under one agreement with one accountable provider. Done properly, the firm gets professionalized operations without hiring six specialists, and the lawyers get their attention back.

Colorado's new rules: House Bill 26-1421

On August 12, 2026, the Colorado Legal Practice Integrity and Fee-Sharing Prohibition Act takes effect. It was enacted as House Bill 26-1421 and codified at C.R.S. sections 13-93-401 through 13-93-407.

The Act's main target is nonlawyer ownership of, and fee sharing with, law firms. The legislature's stated concern was that alternative business structures were increasingly being used to route an economic interest in legal fees to nonlawyers. Section 13-93-404 prohibits a lawyer or law firm from sharing any portion of legal fees or revenues with a nonlawyer or an alternative business structure, and section 13-93-404(2) makes clear that how an arrangement is labeled does not determine whether the prohibition applies. Substance governs, not form.

The Act defines an MSO explicitly

The Act also states that a "law firm" does not include an MSO, which keeps the two categories cleanly separated.

The rule that matters most: how an MSO may be paid

Section 13-93-405 is the operative provision for anyone using or operating an MSO in Colorado. A lawyer or law firm may not compensate or engage an MSO unless the compensation:

• is not contingent upon legal fees, revenues, or profits;
• is not calculated as a percentage of legal fees, revenues, or profits; and
• is not determined by reference to recoveries, settlements, judgment awards, or case outcomes.

Subsection (2) then says what remains permitted, and it is broad: nothing in the section prohibits compensation, including flat fee or hourly payments, or engagement of MSOs, that is not expressly prohibited by the section.

Payments for genuine non-legal services are not "legal fees"

The Act's definition of "legal fee" is deliberately wide, and it reaches revenue collected through affiliated entities, subsidiaries, technology platforms, service providers, and fee-collection intermediaries. That anti-circumvention language is there to stop a percentage of legal fees from being relabeled as something else on its way out the door.

But the definition carves out payments made solely for non-legal goods or services, including administrative, clerical, and operational support, if the payments are reasonably separable from compensation for legal services. That separability standard is what a compliant MSO arrangement has to be able to demonstrate, in its contract and in its books.

Enforcement has teeth

• A client who received legal services provided in violation of the Act may sue and recover economic damages in the amount of the legal fees paid.
• A law firm doing substantial business in Colorado that loses revenue because of another firm's violation may seek injunctive and declaratory relief and disgorgement, but only after giving the Attorney General written notice of the alleged violation, and only if the Attorney General has not brought its own action within sixty days of that notice.
• Funds paid or received in violation are subject to disgorgement to the state general fund.
• A prevailing plaintiff recovers reasonable attorney fees and costs.
• A contract or agreement in violation of the Act is deemed void.

Dates to know

• Effective August 12, 2026. The Act applies to conduct occurring, and to contracts and agreements entered into or renewed, on or after that date. An arrangement signed before the effective date is not grandfathered forever; its renewal is a fresh event.
• Repealed effective September 1, 2029. Part 4 sunsets on that date unless the legislature acts.

The companion law: Senate Bill 26-174 on legal marketing

The same day, Senate Bill 26-174 takes effect, adding C.R.S. section 6-1-741. It makes lead-generation legal marketing a deceptive trade practice. Paying a third party for information about a potential client or case is prohibited, whether the compensation is per lead, per case, by subscription, or routed through intermediaries or affiliates.

This matters for MSOs because marketing is one of the core services an MSO provides. The statute draws the line clearly, and it expressly preserves traditional legal marketing: marketing in which the advertising attorney or firm is clearly identified to the consumer. The statute names search engine optimization, pay-per-click advertising, radio, television, streaming, billboards, and legal directory listings as permitted examples, including when a third party performs the work on the firm's behalf.

The short version for an MSO: run the firm's marketing in the firm's own name, and do not buy leads.

What a compliant arrangement looks like in practice

• A written services agreement that identifies the non-legal services actually provided.
• Fees set in advance as fixed amounts or hourly rates, with billing triggers that do not reference any matter's economic outcome.
• Documentation that the fee is reasonably separable from compensation for legal services, which in practice means invoices, cost records, and books that an accountant or regulator can follow.
• Professional independence preserved in writing, with representation, strategy, fee-setting, and settlement decisions reserved to the firm.
• Marketing conducted in the firm's name, with no purchase of leads or potential-client information.
• Prospective amendments only, so no change to the fee can be made retroactively or by reference to results.
