Contingency Fee Accounting: How a Law Firm Booked Case Costs Wrong

Contingency Fee Accounting: How a Law Firm Booked Case Costs Wrong

Contingency fee accounting looks easy for twenty-two months and then fails on a single afternoon. The afternoon is settlement day, when the fee, the costs and the client's share all have to add up to one check.

Illustrative anonymized composite, drawn from recurring patterns rather than a single engagement. The firm named below was not involved in it. Dollar figures are round and illustrative. Nothing here is guaranteed or predictive.

The firm in this composite is a four-lawyer plaintiff practice. Its fee agreement is the common one: one third of the gross recovery, with case costs reimbursed to the firm out of the client's share. Its bookkeeping rule was also common: pay a filing fee, an expert or a records vendor from the operating account, and code it to "case expenses" when the bill clears.

A firm that works with law firms is Legal Ease Bookkeeping, a law firm bookkeeper covered near the end, after the story. Legal Ease Bookkeeping is a paid featured member of Sam's List.

The Setup Behind This Contingency Fee Accounting Error: Costs With No Receivable

When a firm pays a cost on a client's behalf, it is owed that money back. Under most contingency agreements, repayment comes out of the recovery, and in some agreements the firm absorbs the cost if the case is lost. Either way, the cost should be tracked by matter, usually as an advanced costs receivable on the balance sheet.

This firm expensed every cost the day it was paid. Over twenty-two months, one personal injury matter collected $24,000 of them: filing fees, a medical records vendor, two experts and a court reporter. Each posted to a shared "case expenses" account with a vendor name.

Monthly profit dipped whenever a case was expensive, and no one could ask what a given matter had cost so far. Nobody minded, because the partners watched the bank balance.

The limitation: some firms expense costs as paid deliberately, for simplicity. The trouble is that it removes the ledger a settlement statement depends on. Whether a firm should carry costs as a receivable or expense them also depends on its accounting method and its tax preparer's advice.

Settlement Day: When the Costs, the Fee and the Client Share Did Not Tie Out

The case settled for $300,000. The paralegal drafted the settlement statement from the general ledger and filtered "case expenses" by the client's name. The filter found $19,000. The other $5,000 had been coded to the general account with only a vendor name, and one expert invoice had been paid under the wrong client.

The first draft looked fine, because every line added to $300,000. It was wrong about what the costs were.

Settlement statement	First draft	Corrected
Gross settlement	$300,000	$300,000
Attorney fee (one third)	$100,000	$100,000
Case costs reimbursed to firm	$19,000	$24,000
Client share	$181,000	$176,000
Total	$300,000	$300,000

The gap was caught because the managing partner asked for the vendor bills behind the cost line, not because any report flagged it. The draft had gone to the client in estimate form, so the firm then had to tell the client that the final net would be $5,000 lower than the number discussed. That call is uncomfortable, but it came before the disbursement.

The limitation: a settlement statement is also a professional obligation. ABA Model Rule 1.5(c) calls for a written statement showing the outcome, the client's remittance and how it was determined, and states adopt their own versions. Check your state's rule instead of relying on a general summary like this one.

The Revenue Side: Contingency Fee Revenue Recognition Distorted by Costs

The settlement also showed up wrong in the firm's profit. The $100,000 fee was recorded when the settlement funds cleared, which is a common approach for a firm on the cash method. But the $24,000 of cost reimbursement was also booked as income that month, because nothing was there to offset it.

Across the matter's life, that was a $24,000 expense spread over twenty-two months and $124,000 of income in the settlement month. The two net to the correct $100,000, but the monthly picture was wrong in both directions. Early months looked weaker than they were and the settlement month looked like a record.

Partners drew against that settlement month, and some of what looked like profit was costs coming home.

This is the practical meaning of contingency fee revenue recognition for a firm like this one. The fee is not earned until the case resolves and the money arrives, and the reimbursement of costs is not fee revenue. It repays the receivable. If costs were expensed as paid, as in this story, the reimbursement is income to that extent.

The limitation: the right revenue treatment depends on the firm's accounting method, and firms on an accrual method face additional judgment about when uncertain fees can be recognized. Ask the firm's CPA how to handle it, and do not assume a cash-basis answer applies to you.

The Rebuild: Contingency Fee Accounting With a Matter-Level Ledger

The firm brought in a law firm bookkeeper to do two things. First, rebuild the matter-level cost record from vendor bills, bank activity and the case management system, going back to the start of each open matter. Second, build a settlement statement process that starts from that record.

The rebuild made four changes.

An advanced costs receivable by matter. Each cost is coded to a client and a matter at payment. The bill is not paid without the code. A monthly report shows open costs by matter, with age.

A reconciliation to the case management system. If the ledger says $24,000 and the case file says $23,500, someone investigates before settlement.

A settlement statement built from the ledger, with the vendor bills attached. The fee, costs and client share are computed on one worksheet, and the managing partner signs it before the client sees a number.

A separate rule for reimbursement. The firm's costs come out of the settlement as a reimbursement of the receivable, not as income.

The limitation: the rebuild took about three weeks of bookkeeper time for the open matters, and cost the firm a delayed disbursement on this case. It also cannot recover a cost that was paid under the wrong client and never noticed. Matter coding works going forward, not retroactively for what no one wrote down.

Where Legal Ease Bookkeeping Fits

Legal Ease Bookkeeping is based in Fort Worth, Texas, was founded in 2016, has 12 employees and works with law firms nationwide. Its profile lists a minimum of $500,000 in revenue and law firm bookkeeping as its specialty.

Legal Ease did not work with the firm in this composite, and nothing above describes its results. The reason to name it is the pattern: the profile lists law firm bookkeeping as its specialty, so it is fair to ask whether cost ledgers, settlement statements and trust books are in scope.

Legal Ease has 9 verified client reviews on Sam's List as of 2026-10-02. 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 and do not represent an endorsement by Sam's List. Legal Ease is a paid featured member of Sam's List. Ratings and rankings are not indicative of future performance or results.

The limitation, plainly: a bookkeeper records, reconciles and reports. They do not decide your fee agreement, draft your settlement statement as legal work, or advise on your ethics obligations, and the lawyer remains responsible for the trust account. The $500,000 minimum also puts the smallest practices outside its range.

Frequently Asked Questions

How should a law firm account for contingency fees?

Most firms record the fee when the case resolves and the money is received, and track unresolved cases outside the financial statements. The right treatment depends on the firm's accounting method, so firms on an accrual method should get their CPA's view on revenue timing before relying on a general rule.

What is an advanced costs receivable?

It is an asset account showing what clients owe the firm for costs it paid on their behalf. It goes up when the firm pays a vendor for a matter and down when the settlement or client reimburses it. It lets you see, matter by matter, what the firm has fronted.

Are advanced case costs an expense for a law firm?

Often they should be tracked as a receivable instead, because the firm expects reimbursement. Whether a particular cost is treated as an expense, especially on a lost case or for tax, depends on the fee agreement, your state's rules and your tax preparer's advice.

Why would settlement figures not tie out?

Usually because costs sit in a shared account without a matter code, are coded to the wrong client, or are missing from the ledger the statement is built from. The fix is to reconcile costs by matter to vendor bills before settlement, not on the day funds arrive.

If you cannot say today what your firm has advanced on each open case, ask your bookkeeper for a costs-by-matter report this month. You can browse bookkeepers on Sam's List, including the firm above.
