Law Firm Bookkeeping and Trust Accounting

Law firm bookkeeping records operating revenue and expenses while protecting money held for clients or third parties. Operating cash, client trust funds, settlement activity, retainers, matter costs, payroll, owner distributions, and tax records require separate ledgers and controls.

Trust-account rules are jurisdiction-specific and can change. This educational guide uses current North Carolina State Bar rules as a concrete example, not a universal rule or legal opinion. Every lawyer must confirm the current requirements of every licensing jurisdiction and financial institution.

Separate operating and trust funds

Client or third-party money should never be treated as firm revenue merely because it entered a bank account. Use properly designated trust accounts where required, individual client or matter ledgers, and an operating account for earned fees and firm expenses.

• Operating bank, cards, loans, payroll, payables, and fixed assets
• Trust bank register and individual client or matter ledgers
• Receipts, deposits, authorizations, checks, transfers, and disbursements
• Billing, time, retainers, earned fees, advanced costs, and refunds
• Settlement statements, lien or third-party obligations, and approvals
• Reconciliation reports, bank statements, cancelled items, and audit trails

Three balances must agree

North Carolina’s current rules require monthly reconciliation of the trust-account records with the bank statement and a quarterly report verifying that the general ledger, total positive client-ledger balances, and adjusted bank balance are identical. The responsible lawyer reviews, signs, dates, and retains the reconciliation under the rule.

Other jurisdictions may require three-way reconciliation monthly or use different timing and retention. Follow the stricter applicable rule when several authorities govern the firm.

A controlled monthly process

1. Complete operating and trust transaction entry through the statement cutoff using original bank and matter records.
2. Match each trust receipt and disbursement to the correct client or matter ledger and authorization.
3. Reconcile the trust bank statement, adjusted bank balance, trust register, and total client balances as required.
4. Investigate shortages, negative client balances, stale checks, unidentified deposits, bank fees, and timing items immediately.
5. Reconcile operating accounts, payroll, cards, loans, receivables, payables, and matter costs.
6. Review earned-fee transfers, billing, settlements, owner activity, and financial statements.
7. Obtain required lawyer review and retain the signed reports, statements, ledgers, and support.

Trust receipts and disbursements

Record the date, amount, source or recipient, client or matter, purpose, and method. Deposit funds promptly under the applicable rule and do not disburse before funds are collected or otherwise permitted. Preserve written instructions and authorizations for transfers.

Never use one client’s funds for another client’s obligation. A bookkeeping or bank error that creates a shortage demands immediate escalation under current bar rules, not an unexplained adjustment.

Earned fees and retainers

The engagement agreement and applicable rules determine when a fee is earned and where it is held. The billing system, client ledger, trust ledger, and operating books should agree on invoice, amount earned, transfer date, and remaining client balance.

Use documented authorization and reviewer approval for transfers from trust to operating. Do not sweep rounded amounts or clear old balances without matter-specific evidence.

Settlement accounting

For a settlement, retain the settlement statement, receipt evidence, client approval, fee calculation, cost reimbursement, lien or third-party obligations, disbursement authorizations, and proof of payment. The client ledger should explain every dollar from receipt through final distribution.

Unresolved liens or disputed amounts may need to remain protected under applicable rules. Bookkeeping staff should escalate legal decisions to the responsible lawyer rather than deciding entitlement.

Firm revenue and matter costs

Separate billed fees, unbilled time, collected fees, reimbursable costs, firm-paid client costs, and write-offs. The tax and financial-reporting treatment of advanced costs can vary, so document the firm’s policy and coordinate with the tax professional.

Analyze revenue by practice area, matter, lawyer, originator, or office only when the time and billing data is controlled. Profitability reports should not encourage billing or allocation practices inconsistent with professional rules.

Controls over electronic payments

Use individual access, multifactor authentication, bank alerts, dual approval, and verified payee information. North Carolina rules address who may have signature or electronic-transfer authority and separation from reconciliation responsibilities. Confirm the current rule for the firm.

Independently verify any change to wire instructions using a known telephone number. Email compromise and settlement-wire fraud require documented callbacks, approval thresholds, and incident escalation.

Continuity	Exports, backup, retention, and offboarding	Records trapped in provider portal

A nonlawyer bookkeeper can perform authorized accounting tasks under supervision, but the lawyers retain professional responsibility. Verify the provider’s law-firm experience, software, security, insurance, supervision, and exclusions.

Monthly management reporting

Operating reports can include collected revenue, work in process, receivables, realization, matter costs, payroll, overhead, cash, and practice-area trends. Keep trust balances outside firm revenue and operating cash.

Review aged receivables, unbilled time, unapplied cash, dormant trust balances, stale checks, negative matters, unusual refunds, and changes to closed periods. Legal and ethical exceptions should be escalated immediately.

Records and retention

Maintain bank statements, cancelled items, deposit records, authorizations, client ledgers, trust register, reconciliation reports, billing, settlement records, and accountings for the period required by the governing rules and law. North Carolina’s current rule includes six-year retention for specified reconciliation records.

The firm should control its data and be able to export ledgers and reports. Test backups and a successor procedure before a staff or software transition.

Respond to a trust discrepancy

Stop and preserve evidence when the adjusted bank balance, trust register, and client ledgers do not agree. Identify the affected matter, transaction, amount, date, user, and bank activity. Do not move another client’s money or post a miscellaneous adjustment to conceal the difference.

Notify the responsible lawyer immediately and follow current bar, banking, insurance, client-notice, and reporting requirements. Secure compromised access, contact the bank through verified channels, and retain the audit log and communications. After correction, document cause, authority, revised reconciliation, and preventive control.

Audit readiness

Maintain a monthly package that can be reproduced without the preparer’s memory. It should include statements, adjusted bank calculation, trust register, client-ledger total, outstanding items, signed review, transaction samples required by the jurisdiction, and explanations of exceptions.

Periodically test whether the client-ledger detail, bank records, and accounting software use the same cutoff and whether dormant balances, uncleared checks, unidentified funds, and closed matters receive timely action.
