7 Things to Fix in a Law Firm's Books Before You Add a Second Partner

7 Things to Fix in a Law Firm's Books Before You Add a Second Partner

Adding a partner is the moment your bookkeeping stops being an internal matter and becomes a contract between two people.

Every number that was approximately right while you were solo is about to become a number someone else has an economic claim on. Getting the law firm books before adding a partner into real shape is not administrative cleanup. It is the difference between a partnership agreement that describes reality and one that describes a guess.

Here are seven things to fix first, in roughly the order they bite.

1. Capital Accounts Have to Exist Before the Partner Does

A capital account tracks what each partner has put in, what they have been allocated, and what they have taken out. In a partnership or multi-member LLC it is the spine of the economics.

Most solo firms converting to a two-partner firm have never maintained one, because with one owner the distinction between the business's money and the owner's money was mostly theoretical. It stops being theoretical the day a second person can also take money out.

Set up capital accounts effective on the conversion date, with an opening balance both people agree to in writing. Retrofitting them eighteen months later means reconstructing every transfer in between and arguing about the ambiguous ones.

2. Owner Draws and Owner Compensation Have to Be Separate Lines

If everything you take out of the firm hits one account called "draws," your comp formula breaks in the first quarter.

Compensation is payment for work performed. A draw is a distribution of profit. They are different economically, they are often different for tax purposes depending on entity type, and almost every attorney compensation formula multiplies something by "profit." If comp is sitting inside the profit number for one partner and outside it for the other, the formula produces a number that favors somebody at random.

Split them into distinct accounts now and restate the trailing twelve months so the historical profit figure you negotiate against is apples to apples.

3. Origination and Working Attorney Credit Belong in the Books, Not in Memory

Most small-firm comp formulas split credit between the attorney who brought the matter in and the attorney who did the work.

That split is easy to agree to and hard to administer, because it requires that every matter carry an origination tag and every time entry carry a working attorney. If those fields are not being captured on day one, the first comp calculation becomes a conversation about who remembers what.

Decide the tagging convention before the partnership starts, put it in the practice management system, and make it a required field. This is a ten-minute configuration decision that prevents a recurring argument.

4. The Trust Account Has to Be Clean Before There Are Two Signers

Client trust accounting is the one item on this list that can cost a license rather than money.

A second partner usually means a second signer, and a second signer means the reconciliation discipline of one person is now protecting two. Most state bars require three-way reconciliation, matching the bank balance, the book balance, and the sum of individual client ledger balances, on a defined schedule. If your firm has been doing that monthly and clearing exceptions, adding a signer is routine. If it has not, you are handing a second person shared exposure to an account with unknown breaks in it.

Get to a clean three-way reconciliation with a documented process before the new partner's name goes on anything, and confirm the specific rules with your state bar because they vary.

Legal Ease is a Fort Worth bookkeeping practice founded in 2016 that works with SMB owners and solopreneurs, and law firm books are a core part of what they do. Legal Ease has 9 verified client reviews on Sam's List as of 2026-09-04. Each review is submitted by an individual who identifies as a client of the firm and rates it on communication, subject-matter knowledge, and overall satisfaction. Reviews reflect those individual experiences, do not represent an endorsement by Sam's List, and are not indicative of future results.

The honest limitation on any bookkeeping engagement here: a bookkeeper can get the trust account reconciled and the ledgers accurate, but the ethics interpretation for your jurisdiction is a question for your bar counsel, not your bookkeeper.

5. Unbilled WIP and Aged AR Are the Two Numbers That Set the Price

Buy-in and buyout math almost always references the value of work in progress and accounts receivable, because those are the firm's near-term cash.

Most solo firms know neither number accurately. Time gets entered late, so WIP is understated. AR includes invoices from three years ago that nobody expects to collect, so AR is overstated. Both errors move the price.

Before you negotiate, age the AR honestly and write off what is not collectible, and true up time entry so WIP reflects actual unbilled work. A defensible number that is lower than you hoped is worth more than an optimistic one you have to defend later.

6. The Entity Conversion Needs a Clean Closing Balance Sheet

Admitting a partner often means converting a sole proprietorship or single-member LLC into a partnership, and that conversion has a date.

Your books need to be able to produce a real balance sheet as of that date: cash, AR, WIP if you track it, fixed assets, accrued liabilities, any debt, and the trust liability stated separately from operating cash. That statement is the opening position of the new entity and it will be referenced for years.

If your books cannot produce that today, that is the actual project, and it takes longer than people expect. Start it a quarter before the conversion date, not a week.

7. Expense Rules Get Written Down Before the First Disputed Expense

Every partnership eventually has the conversation about whether the CLE trip, the bar association dinner, or the car is a firm expense.

Having it in advance costs an hour. Having it afterward costs goodwill. Write down which categories are firm expenses, which are personal, what the approval threshold is, and how client-advanced costs are recorded and recovered. Client costs in particular should be tracked as an advance rather than buried in operating expense, because they distort the profit number the comp formula runs on.

None of this is glamorous. All of it is cheaper before the partnership than after.

What This Adds Up To

The pattern across all seven items is the same: a second partner converts informal decisions into contractual ones. Anything your books currently handle by approximation becomes something two people have to agree on.

Fixing them in advance does not guarantee an easy partnership, and a clean set of books will not rescue a bad fit between two attorneys. What it does is make sure the disagreements you have are about strategy rather than about arithmetic.

If your firm's books are not in shape for that conversation, a bookkeeper who has worked inside law firm ledgers and trust accounts is the right first call. You can compare firms and their verified client reviews in the Sam's List bookkeeper directory.

Frequently Asked Questions

How far in advance should a law firm clean up its books before adding a partner? Plan on at least one quarter, and longer if capital accounts do not exist or the trust account has unresolved reconciliation breaks. The binding constraint is usually restating trailing profit so draws and compensation are separated, because the partnership negotiation depends on that number being accurate.

What is the difference between a partner draw and partner compensation? Compensation pays a partner for work performed and generally sits above the profit line. A draw distributes profit that has already been earned. Most compensation formulas multiply something by profit, so if one partner's pay is inside that number and the other's is outside it, the formula produces distorted results.

Does adding a partner change trust account requirements? The underlying rules do not change, but the exposure does. A second signer shares responsibility for an account whose reconciliation history they did not create. Most state bars require periodic three-way reconciliation, and the specific frequency and record retention rules vary by jurisdiction, so confirm yours with your state bar.

Can a general bookkeeper handle a law firm's books? Sometimes, but the trust account is where generalists get into trouble. Client funds have to stay segregated, tracked per client, and reconciled three ways, and the consequence of getting it wrong is a bar complaint rather than an amended return. Ask any candidate how many law firms they currently serve and how they run trust reconciliation.
