Three-way trust reconciliation is a process that confirms funds held on behalf of clients or third parties are properly accounted for. It compares three separate records that should all show the same total: the bank statement balance, the general ledger balance for the trust account, and the combined total of all individual client or matter ledgers.

The bank statement shows what the bank says you have. The general ledger shows what your accounting records say you have. The individual client ledgers show what you owe to each specific client whose money you’re holding. All three numbers must match. If they don’t, something is wrong and you need to find it.

Property managers, real estate brokers, attorneys, and HOA management companies typically need this reconciliation because they hold money that belongs to other people. Security deposits, escrow funds, client retainers, and reserve funds all require careful tracking. Mixing up whose money is whose or having a discrepancy between what you think you have and what the bank shows creates serious problems.

Regular bank reconciliation only compares two things: your books and the bank statement. That tells you whether transactions were recorded correctly. Three-way reconciliation goes further by also verifying that every dollar in the trust account can be traced to a specific client or purpose. This matters because you could have a reconciled bank balance that still has errors in how funds are allocated between clients.

Real estate and property management businesses in California face specific requirements around trust account handling. The Bureau of Real Estate requires brokers to reconcile trust accounts at least monthly. Property managers holding tenant security deposits need to prove at any time exactly how much belongs to each owner or tenant. A three-way reconciliation provides that proof.

When the three totals don’t match, the discrepancy usually comes from one of a few sources. Unrecorded transactions, duplicate entries, deposits applied to the wrong client, or timing differences between when money moves and when it gets recorded. Finding the error requires working through each component until you locate where the records diverge.

Most San Diego bookkeeping services that work with trust accounts perform this reconciliation monthly. Some businesses with high transaction volumes do it weekly. The frequency depends on how much money moves through the account and how quickly you need to catch errors.

Getting this wrong has real consequences. Beyond regulatory penalties, you could end up paying out money to one client that actually belonged to another. Rebuilding trust records after they’ve been poorly maintained is expensive and time-consuming. Monthly reconciliation catches small problems before they become big ones.
