Financing a Law Firm Acquisition, Merger or Partner Buyout

By MercFinancial · Published 2026-10-21

Law firm acquisition financing combines SBA 7(a) or bank term debt with a seller note and often an earn-out, priced on whether clients follow the practice. How a firm is valued, structured and financed.

A law firm acquisition, merger or partner buyout is financed with some combination of an SBA 7(a) loan or bank term debt, a seller note, the buyer's own equity, and in non-SBA deals an earn-out that ties part of the price to the clients who actually stay. Law firms are eligible for SBA lending under 13 CFR 120.110, and 7(a) loans are commonly used for a change of ownership, including the purchase of a partner's interest, subject to the SBA's current rules on equity injection and seller financing. Every lender prices the same risk: a practice is worth what its clients do after the closing, and clients are free to leave.

This guide covers how a law practice is valued, the capital stack lenders expect, how SBA 7(a) treats a practice purchase and a partial buyout, what the seller note and earn-out do, the ethics limits on paying a departing or deceased lawyer, and the documents a buyer needs ready.

A law practice is worth what its clients do after the closing, and every lender prices that before anything else.

How a law practice is valued for financing

There is no single rule for valuing a law practice, and lenders know it, so they start with what transfers. A practice built on recurring institutional clients, estate plans that come back for updates, or a business clientele with ongoing needs is valued on a multiple of collected revenue or of the seller's discretionary earnings, and a practice built on one lawyer's personal relationships is valued lower because the relationships may not survive the sale. Contingency practices are valued largely on the docket: the open matters, their stages, the costs advanced and the expected fees, with a discount for the chance that clients choose other counsel.

Billed receivables and work in process are usually priced separately from goodwill, or excluded and collected for the seller's account, and client funds in trust are never part of the price. SBA lenders require an independent business valuation on larger change-of-ownership loans, and most bank lenders want one too. A price the appraisal does not support is the most common reason a law firm purchase fails to finance, because no lender will fund goodwill it cannot see.

The capital stack for a law firm acquisition, with an illustrative example

Lenders expect the price to be paid from several layers, each carrying part of the risk.

• Buyer equity. Cash from the buyer, commonly around ten percent of total project cost under the SBA's current rules, and often more in a bank-financed deal.
• Senior term loan. An SBA 7(a) loan or bank term debt, repaid from the practice's cash flow, commonly on a ten-year amortization for a business purchase.
• Seller note. Part of the price the seller carries. In an SBA deal a note on full standby for the life of the loan can count toward part of the equity requirement, and a note that is not on standby is counted against cash flow.
• Earn-out. In a bank or seller-financed deal, payments tied to retained clients or revenue. SBA rules generally do not allow a contingent earn-out in the financed price, so an SBA deal uses a fixed price and a seller note instead.

Illustrative example, round numbers only: a $1,000,000 practice purchase with $50,000 of closing costs is funded with $105,000 of buyer cash, a $745,000 SBA 7(a) loan and a $200,000 seller note on full standby. The buyer's cash plus half of the standby note meets an illustrative ten percent injection, and the senior loan is sized to collected fees after the buyer's salary. The figures are not terms from any funding source, and the general mechanics of buying any business are in business acquisition financing options.

SBA 7(a) for a law practice purchase or partner buyout

Because law firms are not on the ineligible list in 13 CFR 120.110, an SBA 7(a) loan is the most common senior debt in a smaller practice purchase, and it can also fund working capital and a buildout. The SBA's current standard operating procedure shapes the deal in a few specific ways.

• A complete change of ownership requires a buyer equity injection, and a seller note counts toward part of it only on full standby for the life of the loan, with interest accruing rather than paid.
• A partial change of ownership, such as buying a retiring partner's interest, is structured as a purchase of the entity's ownership interest rather than its assets, and the remaining owners are expected to sign personal guaranties.
• The seller may stay on for a limited transition period as an employee or consultant, which is also what the lender wants for client retention, but not as an owner.
• An independent valuation supports the price, and the lender tests the practice's cash flow after the buyer's reasonable compensation against the new debt service.

The lender confirms the current requirements, which change with each revision. The general requirements for any SBA file are in the SBA loan requirements checklist, and an SBA 504 loan is the usual answer when the purchase includes the office building.

Seller notes, earn-outs and the ethics limits on paying a lawyer

The seller note aligns the seller with the buyer's success, and lenders like it for that reason. It is subordinated to the senior loan, often amortizes only after a period, and gives the seller a reason to make the client transition work. An earn-out does the same job more precisely in a non-SBA deal, paying the seller a share of the revenue that actually stays over one to three years.

The rules of professional conduct draw the limits. The sale of a practice is governed by rules modeled on ABA Model Rule 1.17 in most states, which generally require the sale of the entire practice or an entire area of practice, written notice to clients, and no fee increase because of the sale. A departing partner's payout can be structured as a purchase of the partner's interest or a retirement payment under the firm's agreement, and rules modeled on Rule 5.4 permit payments to a deceased lawyer's estate for the purchase of a practice. Fee sharing between the buyer and a seller who moves to another firm follows the rule on dividing fees between lawyers, which requires client consent. Two practical consequences: a non-lawyer cannot buy the firm, and a non-compete that bars the seller from practicing is unenforceable under rules modeled on Rule 5.6, so client retention rests on the transition plan and the seller's incentives, not on a covenant.

What lenders require from a law firm buyer, and the mistakes that stop a deal

Deals fail on a price the valuation cannot support, on paying for receivables twice, on a seller who leaves at closing, and on projections that assume every client stays. After closing, a working capital line sized to the new firm's collections is the usual companion, described in law firm lines of credit, and the other structures are in law firm financing options.

Where MercFinancial fits

MercFinancial is a commercial funding brokerage in Houston, not a lender. For a practice purchase or buyout, a funding specialist reads the seller's collected fees, the client base, the proposed price and the transition plan, and works out which stack the file supports before it goes anywhere. The request then goes to the funding sources among more than 160 wholesale and institutional relationships whose credit policy allows law firms and change-of-ownership lending, including SBA lenders, and the offers are compared on amount, term, injection, standby requirements and guaranty. Approval and every term are the funding source's decision, and if the price cannot be financed as proposed, the buyer hears that before the letter of intent. The other law firm funding guides cover the structures that follow closing, and the business funding programs page lists what is placed.

Frequently Asked Questions

Can I get an SBA loan to buy a law practice?

Yes. Law firms are not among the ineligible businesses in 13 CFR 120.110, so a lawyer buying a practice can apply for an SBA 7(a) loan through an SBA lender, which can also fund working capital and improvements. The buyer injects equity, a seller note on full standby can count toward part of it, and the lender wants an independent valuation and a transition plan.

How much down payment does a law firm buyout need?

Under the SBA's current rules a complete change of ownership requires a buyer equity injection commonly around ten percent of total project cost, and a seller note on full standby for the life of the loan can satisfy part of that. Bank-financed deals often ask for more. Partial buyouts of a partner's interest follow their own SBA rules, and the lender confirms the exact requirement for the file.

Can a non-lawyer buy a law firm?

Generally no. Rules of professional conduct modeled on ABA Model Rule 5.4 bar non-lawyer ownership of a law firm and the sharing of legal fees with non-lawyers, with narrow exceptions in a small number of states that have authorized alternative structures. A buyer of a practice must be a lawyer licensed in the jurisdiction, which is also what a lender will verify before funding the purchase.

Can a law firm acquisition include an earn-out?

In a bank-financed or seller-financed deal, yes, and an earn-out tied to retained revenue is a sensible way to share the client retention risk. SBA rules generally do not permit a contingent earn-out as part of the price financed with a 7(a) loan, so an SBA deal uses a fixed price with a seller note, often on standby, to give the seller a stake in the transition.

What happens if clients leave after I buy a law firm?

The debt remains and the revenue does not, which is why lenders underwrite retention before anything else. A transition period with the seller, joint client notices and referral source introductions reduce the loss, and a seller note or earn-out shares it. Because lawyer non-competes are unenforceable under rules modeled on Rule 5.6, build projections that survive losing a share of the clients and still cover debt service.
