Contingency fee law firm cash flow: How to cover costs between settlements

Contingency fee law firm cash flow is lumpy by design: the firm pays payroll, rent, and case costs for months or years, then receives a fee when a matter resolves. Numetix builds a rolling forecast from the matter list and the ledger. This guide explains the gap, a forecasting routine, and how to cover it safely.

QUICK ANSWER: HOW DO CONTINGENCY FEE FIRMS MANAGE CASH FLOW?

• Forecast by matter stage, using cautious timing for each expected resolution, and add fixed overhead and advanced costs on top.

• Hold a cash cushion sized to your fixed monthly costs, and agree a credit line before you need it rather than during a shortfall.

• Never use client trust money to fill a gap, because commingling is a violation even if the money is replaced quickly.

Numetix is the expert-led, AI-powered, human-in-the-loop bookkeeping layer for law firms, so trust, operating, and cost ledgers are reconciled by software and reviewed by a named person. The sections below cover why the gap exists, a forecasting routine, and the rules that limit how a gap can be covered.

Why do contingency fee firms run short of cash?

The fee is earned only on a recovery. Rule 1.5(c) requires the agreement to be in writing and to state the percentages and the expenses to be deducted from the recovery (ABA Model Rule 1.5). Until a matter resolves, the firm has recorded time that earns nothing and, usually, advanced costs that are not yet repaid. Payroll and rent do not wait. The contingency fee glossary entry gives the short definition.

How do you forecast it?

1. List every open matter with its stage and the earliest and latest realistic resolution dates.

2. Estimate the fee and the costs to be reimbursed for each, and use cautious timing.

3. Add fixed overhead and the costs you expect to advance each month.

4. Roll the forecast forward week by week and update it at each close.

5. Compare forecast with actual and learn which stages slip most.

Our guide to the 13-week cash flow forecast for service firms shows the format, and the lockup days glossary entry explains how long money stays tied up.

What cushion does the firm need?

For example, a firm with $60,000 of fixed monthly costs and $12,000 a month in advanced costs spends $72,000 a month before any fee arrives. If the longest realistic gap between large fees is four months, it needs about $288,000 in cash or credit to cover it. The figures are illustrative, and the right number depends on how many matters are near resolution.

How can the firm cover a gap safely?

• Keep a cash reserve sized to fixed costs.

• Arrange a line of credit while the firm's cash position is strong.

• Time discretionary spending and hires to expected receipts.

• Move fees from trust to operating promptly once they are earned and the client has been paid.

• Review the advanced cost balance, because old advances tie up cash.

What must the firm never do?

Never use funds that belong to clients to cover operating costs, even briefly. Rule 1.15 requires client property to be held separately and delivered promptly (ABA Model Rule 1.15). Our guides to what happens when a lawyer commingles trust funds and to keeping trust funds separate from operating explain the consequences and the controls.

Frequently asked questions

How long does cash stay tied up in a contingency matter?

It depends on the matter type, the court, and the other side. Some resolve in months and others take years, so the firm should not assume a single average. Use a range for each matter, forecast with the cautious end, and update the dates at every month-end close.

Can a firm borrow against expected settlements?

Some firms use credit lines or litigation funding, but each arrangement has ethics and disclosure rules that vary by state. Read your state bar guidance before you sign anything, and keep the lender's repayment mechanics separate from client trust funds so client money is never at risk.

When can the firm take its fee out of trust?

Only when it is earned and no one disputes it, and after the settlement statement is prepared. Rule 1.5(c) requires a written statement showing the outcome and the client's remittance. Move the fee to operating then, and record the transfer on the client's ledger the same day.
