Bookkeeping for personal injury law firms

Updated October 16, 2026

Personal injury bookkeeping differs from general law firm bookkeeping in three places: revenue arrives irregularly through contingency fees rather than steady billing, the firm often advances substantial case costs long before recovery, and settlements involve a disbursement sequence — client funds, liens, case costs, and firm fee — that must be recorded accurately, matter by matter, in the trust records.

Who this is for

Contingency-fee practices carrying case costs for months or years, firms whose monthly profit swings with settlements, practices handling medical liens at disbursement, and firms adding case-cost funding or a line of credit.

What the workflow needs to handle

Advanced case costs tracked per matter as recoverable amounts, the settlement disbursement sequence recorded against the settlement statement, documented lien and third-party payoffs, reporting that separates settlement-driven revenue from the ongoing cost base, case-cost cash planning, and trust discipline at high matter volume.

Questions before hiring

How do you record advanced case costs and where do they appear on the balance sheet? How do you reconcile a settlement disbursement against the settlement statement? How are lien payoffs documented? Can you report outstanding advances by open matter?

Frequently asked questions

Are advanced case costs an expense?

Treatment depends on the firm's accounting method, fee agreements, and tax position. Many firms track them as recoverable amounts rather than immediate expenses, but this is a question for your CPA.

How should settlement funds be handled?

Settlement proceeds generally pass through the client trust account and are disbursed according to the signed settlement statement, with each payment recorded against that matter. Specific requirements vary by jurisdiction.

Why does our monthly profit look so inconsistent?

Contingency revenue is lumpy while overhead is steady. Reporting that separates recurring costs from settlement-driven revenue usually makes the pattern easier to manage.

Do we need a bookkeeper who has handled PI firms?

Experience with case costs and settlement disbursements shortens the learning curve, but the more important test is whether the provider can describe the disbursement and reconciliation process clearly before starting.
