Bookkeeping boundaries for law firm trust accounts

This article describes a control-oriented bookkeeping workflow, not legal advice. Rules for lawyer trust accounts vary by jurisdiction and sometimes by the type of funds or engagement. The firm's designated lawyer or compliance owner should translate applicable requirements into written instructions and remain responsible for legal and ethical decisions.

For every bank account, the procedure should state whether it is a trust account, operating account, or another specifically defined account. Record the financial institution, masked account identifier, entity or office, general-ledger account, approved signers, and the lawyer responsible for oversight. Do not combine trust and operating transactions in one undifferentiated reconciliation workbook.

An operating account records the firm's receipts and expenses. A trust bank account requires an additional layer: the accounting control balance must also be supported by individual client or matter ledgers. The bookkeeping map should identify:

• the trust bank account and its corresponding general-ledger control or liability account;
• the client and matter identifier used in the legal practice system and accounting records;
• the source of deposit, disbursement, and transfer instructions;
• who may create or edit a matter ledger;
• who may approve a trust transaction;
• where bank statements, deposit support, approvals, and reconciliation evidence are retained; and
• which lawyer or firm officer reviews exceptions and the completed reconciliation.

Separate identifiers matter. Two clients may have similar names, and one client may have several matters. A stable matter ID is safer than free-text descriptions when allocating a receipt or disbursement.

Each trust transaction should be posted both to the trust control structure and to the correct matter ledger. A useful matter ledger shows the transaction date, effective or cleared date where relevant, payee or payer, amount, receipt or payment reference, purpose, source-document link, and running balance. Corrections should remain traceable; overwriting an old description or changing a matter without an audit trail makes later review harder.

Before posting a deposit, the preparer should be able to identify the bank account, client, matter, source of funds, purpose, and date received. Unidentified receipts belong in an exception process defined by the firm, not in whichever matter seems most likely. Before preparing a disbursement, the support should identify the matter, intended recipient, purpose, available ledger balance, written authorization, and any other evidence required by the firm's procedure.

A bookkeeper can check whether the record is complete and whether the proposed transaction fits the written instructions. The bookkeeper should not decide that funds have been earned, that a disputed amount may be released, that one matter may fund another, or that an exception is permitted. Those are questions for the designated lawyer or authorized firm decision-maker.

A bank reconciliation alone does not establish that the trust records agree at matter level. A three-way reconciliation compares three values as of the same cutoff date:

1. Adjusted bank balance. Start with the bank statement ending balance, then list reconciling items such as deposits in transit and outstanding checks using the firm's approved treatment.
2. Trust general-ledger balance. Use the balance of the ledger account tied to that bank account, after identifying rather than concealing unexplained entries.
3. Total of individual matter ledgers. Produce a complete matter-balance listing for the same account and cutoff, and total it without omitting inactive matters that still have balances.

The workpaper should show each amount, the reports and bank statement used, the report parameters, and any difference between the three. Reconciliation means differences are explained and resolved under the firm's procedure - not that a plug entry is posted so the totals appear equal.

Supporting schedules should list outstanding checks, deposits in transit, other reconciling items, and unresolved bank activity. Tie each schedule total to the reconciliation. Save the underlying matter trial balance or ledger report used that day; a later rerun may change if backdated activity is entered.

The preparer should stop and promptly notify the named reviewer when an item falls outside the procedure. Examples include:

• a negative matter balance or a disbursement that would create one;
• a trust-bank balance, general-ledger balance, and matter total that do not agree;
• an unidentified deposit or withdrawal;
• a transaction posted to trust that appears to relate to firm operations, or vice versa;
• a transfer to operating without the approval and support required by firm policy;
• a stale outstanding check or old unapplied matter balance;
• bank fees, interest, reversed items, or electronic debits without a defined treatment;
• a proposed transfer between matters; and
• altered payment instructions or an unexpected recipient.

The exception log should contain facts rather than conclusions: account, matter, date, amount, source links, what was compared, current status, assigned lawyer, and requested decision. Do not use an adjusting entry, suspense matter, or generic client name to make an unexplained difference disappear.

A scoped bookkeeping role can collect statements, import or record authorized transactions, maintain matter-ledger detail, prepare deposit and outstanding-item schedules, draft the three-way reconciliation, and follow up for missing documents. The role can also package exceptions so the lawyer can decide efficiently.

The firm's authorization matrix should separately address opening accounts, adding signers, initiating and approving payments, signing checks, moving funds to operating, writing off balances, editing vendor or recipient details, and posting reconciliation adjustments. System permissions should mirror that matrix. If banking or accounting software cannot enforce separation, add a documented compensating review rather than assuming a shared login is adequate.

Offshore location does not change the need for supervision, confidentiality, and restricted access. The firm should decide which documents may be accessed, from what environment, and whether client or matter data must be masked in operational trackers. Support personnel should receive only the permissions and information required for their assigned work.

The reviewer needs more than a completed checkbox. A review packet should include the statement, three-way reconciliation, matter-balance total, reconciling-item schedules, ledger activity, unresolved exceptions, and proposed adjustments. The reviewer should be able to trace totals to reports and selected entries to source authorization.

The firm's written policy should set frequency, timing, evidence of review, retention, and escalation based on applicable jurisdictional guidance. It should also state who acts when the usual reviewer is unavailable. The completion record can identify preparer, preparation date, reviewer, review date, follow-up items, and final disposition.

For industry-specific process planning, law firm bookkeeping support can organize supervised reconciliation schedules and matter-cost records, while monthly close support can place the work on a recurring calendar. Neither service definition replaces instructions approved by the firm's lawyer or advice from qualified counsel in the relevant jurisdiction.
