Lawyer trust accounting is the part of running a firm where a bookkeeping slip and an ethics violation look identical from the outside. The duties themselves are short enough to read in ten minutes. What trips firms is the recordkeeping underneath them, and the state bars that have started checking are finding the same gaps in firm after firm.
Key takeaways
- A client trust account holds money that belongs to clients and third parties. It is kept completely separate from the firm’s own funds, and the firm is a custodian of it, not an owner.
- The safekeeping rule, numbered 1.15 in most states, sets the duties. A separate recordkeeping rule sets the paperwork, and that is where firms actually fail.
- When California reviewed volunteer firms in its pilot compliance program, 89 percent had noncompliant client ledgers and 83 percent had noncompliant three-way reconciliations.
- Washington requires nine categories of trust records kept for seven years. Florida requires eight, kept six years after the representation ends.
- A monthly three-way reconciliation is the control designed to surface those errors before a bank overdraft notice does. Florida requires it monthly and Washington at least quarterly.
- An overdraft is reported to the bar by the bank whether or not the check is honored, and in Florida it is listed cause for an audit.
What lawyer trust accounting actually is
A client trust account is a dedicated bank account where a lawyer holds money that belongs to someone else: unearned fees, settlement proceeds, filing-fee advances, or funds held for a third party. It sits entirely apart from the firm’s operating account, and the governing idea is simple. The money in it is not yours. You are holding it until the moment you have properly earned it or are required to pay it out to someone.
Trust accounting is the bookkeeping that proves you did that. It is not an accounting specialty and it is not optional for firms that touch client money, which is nearly all of them. It is also only one of the sets of books a firm keeps, and our treatment of law firm accounting covers the other two, the tax records and the management numbers, and how they reconcile to this one. The states write the duty in almost identical language. Florida requires a lawyer to hold client and third-party funds “in trust, separate from the lawyer’s own property,” in an account “clearly labeled and designated as a trust account.” Washington puts the prohibition first: a lawyer “must not use, convert, borrow or pledge client or third person property for the lawyer’s own use.”
Florida goes further and names the consequence of getting it wrong. Money entrusted for a specific purpose “is held in trust and must be applied only to that purpose,” and a refusal to account for it and deliver it on demand “is conversion.” That is the whole risk in one sentence. A trust-account failure is not filed away as sloppy bookkeeping. It is treated as taking money that was never yours.
IOLTA, or Interest on Lawyers’ Trust Accounts, is one type of pooled trust account rather than a separate obligation. When client funds are small or held briefly, the interest they would earn individually is less than the cost of the account, so those balances are pooled and the interest is directed to civil legal aid. Whether a given client’s money belongs there turns on a net-return test written into the rule. For the mechanics of that test and how enrollment works, see our explainer on what an IOLTA account is. Everything below applies to a trust account whether or not it happens to be an IOLTA one.
What the safekeeping rule requires of you
Nearly every trust obligation you have comes out of one rule, numbered 1.15 in most states and sometimes split into lettered parts. The American Bar Association publishes a model version, and states adopt and renumber it, so the authoritative text for you is your own state’s. Read side by side, the adopted versions come down to the same short list of duties.
| The duty | What the adopted text says |
|---|---|
| Separate the funds | Client money lives in the trust account and firm money does not, with one narrow exception. Both Washington and Florida permit the lawyer to keep enough of their own money in the account to cover bank charges, and only that much. |
| Hold advance fees until you earn them | Washington requires legal fees and expenses paid in advance to be deposited into trust and “withdrawn by the lawyer only as fees are earned or expenses incurred.” |
| Give notice before you take a fee | Washington permits withdrawal of earned fees “only after giving reasonable notice to the client of the intent to do so, through a billing statement or other document.” The bill is not a formality. It is the event that makes the transfer permissible. |
| Notify and deliver promptly | On receiving funds a client or third person has an interest in, you must promptly tell them, and promptly deliver what they are entitled to receive. On request you must render a full accounting. Washington adds a written accounting at least annually for as long as you hold the funds. |
| Hold disputed money | If two or more people claim an interest, including you, the disputed portion stays in trust until the dispute is resolved, and the undisputed portion goes out promptly. |
| Never borrow | The account is not a credit line. Washington states it as a flat prohibition on using, converting, borrowing or pledging client property for the lawyer’s own use. Covering payroll from it, even briefly and even with every intention of replacing the money, is the conduct the rule was written to prohibit. |
Two mechanical rules do more work than their length suggests. Washington requires that receipts be “deposited intact,” which forbids splitting one settlement check between the trust account and the operating account, and requires that withdrawals be made “only to a named payee and not to cash.” It also bars disbursing against funds that have not cleared, and it bars a disbursement on one client’s behalf from exceeding that client’s own balance. That last one is the definition of the most common serious violation there is: using one client’s money to cover another client’s costs, usually without anyone intending to. It happens when a firm reads the account balance instead of the ledger balance, sees enough money to cover a disbursement, and writes the check. The bank clears it because the pooled account holds the funds. The client whose ledger it came out of has, at that moment, been used to finance somebody else’s matter.
The records your state makes you keep
The duties above are the part firms usually know. The recordkeeping rule is the part that produces the discipline, because a duty you honored but cannot document looks the same on review as one you ignored. Washington splits it out into its own rule, RPC 1.15B, which opens with the retention period: trust records “may be in electronic or manual form and must be retained for at least seven years after the events they record.” It then lists nine categories, all of them required at minimum.
| Record | What it has to show |
|---|---|
| Check register for each trust account | Every receipt, disbursement and transfer, each entry carrying the client matter, the date, the check number, the payor or payee, and the new account balance after that entry. |
| Individual client ledger records | A separate page or electronic record per client, with the purpose of each movement, the date, the check number, the payor or payee, and the new client balance after each entry. |
| Fee and cost agreements | Copies of any agreement covering fees and costs. The rule does not require a written fee agreement, but if one exists it is a trust record. |
| Statements and accountings to clients | Copies of anything you sent a client or third party showing funds disbursed to them or on their behalf. |
| Bills rendered | Copies of the bills for legal fees and expenses you sent, which are also the documents that authorize a fee transfer. |
| Supporting documents for disbursements | The invoices and bills behind every disbursement or transfer out of the account. |
| Bank records | Bank statements, copies of deposit slips, and cancelled checks or their equivalent. |
| Reconciliations | Copies of every trust account bank reconciliation and every client ledger reconciliation. |
| Financially relevant parts of the client file | Only the portions reasonably necessary to understand the financial transactions, such as a settlement agreement, rather than the whole file. |
Florida’s list is structured differently and lands in the same place: eight minimum records, retained “for 6 years after the final conclusion of each representation in which the trust funds or property were received.” Two of Florida’s requirements are worth borrowing whatever state you are in. Every disbursement check must “clearly identify the client or case by number or name in the memo area of the check,” and every wire in or out must be documented down to the routing numbers and names on both sides, the account holder’s name and address, and the purpose of the transfer, with the example the rule gives being as specific as “payment on invoice 1234.”
Florida also puts a governance requirement on any firm with more than one lawyer: a written plan for supervision and compliance, distributed to every lawyer in the firm, naming the signatories, the lawyer responsible for reconciling the account monthly and annually, and the lawyer who answers questions about it. It has to be reissued whenever those names change. Solo firms are exempt from the writing, not from the thinking, and the exercise of naming who is responsible is worth doing at any size. The value of the exercise is that it forces a firm to answer a question most never ask out loud, which is who would notice first if the account went wrong, and by what date each month they would notice it.
Two of the nine records above are the ones that go missing. The first is the individual client ledger, because a firm that keeps a tidy check register often assumes the register is enough. It is not, and it cannot answer the only question that matters during a review, which is how much of the balance belongs to each client. The second is the saved copy of each reconciliation. Performing the reconciliation and not keeping it is a compliance failure on its own terms, and it is also how a firm loses the ability to show that a problem found later did not exist before.
How money actually moves through the account
The rules read abstractly. Watching one matter move through the account from the first deposit to a zero balance makes the mechanics concrete, and it shows where each rule bites. Take a client who signs a fee agreement and pays $4,435 up front: $4,000 as an advance against fees and $435 for the court filing fee. That entire amount is client money on the day it arrives. None of it is yours yet, including the portion that everyone in the room expects will eventually be earned, and the fee agreement both parties signed does not change that. The money becomes the firm’s in pieces, on specific dates, each of which has to leave a trace in two places.
Three things are happening in that sequence that the rules care about. The deposit goes in intact, as a single item, rather than being split so the filing-fee portion lands in operating. The filing fee leaves by check to a named payee, the court, with the client identified in the memo line. And each fee transfer happens only after a bill was sent, because the bill is the reasonable notice that makes the withdrawal permissible. Reverse the order, move the money first and bill afterward, and the transfer was a withdrawal of client funds at the moment it happened, regardless of how the month ends.
The other thing to notice is the last column. The matter does not end when the work ends. It ends when the balance reaches zero, which means refunding the unearned remainder and sending a written accounting for it. A ledger left sitting at a small positive balance for years is one of the most common findings in a review, and it is usually not theft. It is a closed file nobody went back to, usually because the closing routine ended at the final invoice rather than at a zero balance.
Written out as the client ledger the rule actually asks for, the same matter looks like this.
| Date | Description | Payor or payee | In | Out | Balance |
|---|---|---|---|---|---|
| Mar 3 | Advance fee and filing cost, deposited intact | Client | $4,435 | $4,435 | |
| Mar 11 | Filing fee, check 1042, client named in memo | Clerk of court | $435 | $4,000 | |
| Apr 1 | Fee earned per invoice 118, sent Mar 28 | Firm operating account | $1,250 | $2,750 | |
| May 1 | Fee earned per invoice 131, sent Apr 27 | Firm operating account | $1,800 | $950 | |
| Jun 2 | Fee earned per final invoice 149, sent May 29 | Firm operating account | $600 | $350 | |
| Jun 5 | Unearned balance refunded, check 1108, accounting sent | Client | $350 | $0 |
Six lines, and every element the recordkeeping rule asks for is on the page: the date, the purpose, the check number, the payor or payee, and the new balance after each entry. The same six movements also appear in the check register, mixed in with every other client’s activity, which is why the two records are not redundant. The register proves what the account did. The ledger proves whose money it was.
The mistakes that get lawyers disciplined
The violations that draw discipline are rarely exotic. They are ordinary bookkeeping failures that compound quietly until something forces them into the open. Most of what firms hear about trust-account discipline arrives as an anecdote, a story about someone a few counties over, told at a bar association lunch and rarely followed up, which makes it easy to file the risk under other people’s problems and move on to the next thing. California replaced the anecdote with a sample. The State Bar there launched its Client Trust Account Protection Program, known as CTAPP, and ran a voluntary pilot in 2024 in which 21 law firms invited a reviewer to examine their records. The reviews completed on 18 of those firms produced this picture.
Read the top three bars together and the shape of the problem is clear. The failures are not about where the money went. They are about the records that would show where it went: the per-client ledger, the journal, and the reconciliation that ties them to the bank. These were volunteers, firms confident enough in their systems to raise a hand, and the reviews still found noncompliant records in most of them. The State Bar’s own summary is blunt about how widely that holds. Through the first two years of the reviews, it says, it has “often found attorneys, whether at large firms, medium-size firms, or solo practitioners, are not complying with important recordkeeping requirements which, if were in place, would prevent negligent trust fund management errors.”
Behind those percentages sit a handful of recurring mistakes. Paying an operating or personal expense directly from the trust account. Leaving earned fees sitting in trust, or sweeping them to operating before the bill went out, both of which are forms of commingling. Covering a shortfall in one matter with another client’s balance. Keeping a check register but no per-client ledger. And skipping the reconciliation, which is what allows every one of the others to run unnoticed until the bank sends a notice to someone other than you.
What happened when one state started counting
California is worth watching because it is the one jurisdiction publishing a before-and-after. CTAPP, launched in fiscal year 2023, requires nearly every California lawyer to register IOLTA and non-IOLTA accounts annually at renewal, complete a self-assessment of trust account management practices, and certify compliance with the safekeeping requirements. On top of that reporting, it began reviewing actual records: the 2024 pilot, then 100 randomly selected attorneys in 2025 whose 2024 recordkeeping was examined, and in 2026 a further 400 attorneys drawn from a cross-section of the population, this time covering 2025 records. Alongside that, the number of bank-reported insufficient funds actions on client trust accounts has moved.
Treat that as one state’s experience rather than a rule about anywhere else, and be careful about what it does and does not show. It counts bank reports, not violations, and a fall in reported items is not by itself proof that fewer errors occurred. What it does establish is that the level of attention a firm pays to its trust account is not fixed. It responds to being asked about it. The practical implication for a firm in any state is that the annual questions the bar asks, or does not ask, are a poor measure of what your records should look like. The standard is in the recordkeeping rule, and it applies whether or not anyone is checking this year.
What a trust-account problem actually costs
Two things happen when a trust account goes wrong, and neither of them starts with a client complaint. The first is the bank. Every state that authorizes trust depositories requires the bank to tell the regulator about trouble. Washington’s rule is representative: a financial institution has to report any properly payable instrument presented against a trust account containing insufficient funds, “whether or not the instrument is honored,” and it has to report within five banking days. The lawyer has a parallel duty. On learning of it, the lawyer “must promptly notify the Office of Disciplinary Counsel” and must include “a full explanation of the cause of the overdraft.” Florida requires the same authorization to be given to the bank at the moment the account is opened.
Florida lists ten separate events that are cause for the bar to order an audit of a trust account, and a returned check for insufficient funds is one of them. So is failing to file the annual trust accounting certificate, which Florida lawyers must submit between June 1 and August 15 each year, and which turns a member delinquent and ineligible to practice if it has not been filed by September 30. So is the filing of a claim against the lawyer with the Clients’ Security Fund. Several of the other triggers have nothing to do with the account at all: a petition for creditor relief filed on the lawyer’s behalf, felony charges, a request from a grievance committee, a court order, or an order of disbarment. The common thread is that the bar reserves the right to look at the records whenever something else has gone wrong, which means the records have to be defensible on a day you did not choose. The cost provision is worth reading twice: an ordered audit is at the lawyer’s own expense when the audit shows the lawyer “was not in substantial compliance with the trust accounting requirements.” Reconciling monthly and keeping the paperwork does not make a firm immune to being audited. It puts the firm on the side of that provision where the cost of the audit is not its own.
The second thing that happens is the complaint file. Florida publishes its discipline mix annually, and trust accounting issues were the third most common category of complaint against Florida lawyers in 2024, behind interference with the administration of justice and neglect. That year the Bar’s intake operation opened 3,659 files, 235 discipline cases were filed with the Florida Supreme Court, and 18 lawyers were disbarred. Where client money was actually lost, the Clients’ Security Fund reimbursed 81 claims totalling nearly $1.8 million in 2024, part of more than $9 million paid out over five years.
That fund exists because trust-account failures happen often enough that clients need a backstop. None of this means a careful firm is one slip from disbarment. The point is narrower and more useful: the trust account is the one part of a practice that reports on itself to a regulator, without waiting for anyone to be unhappy. That is an argument for a routine, not for anxiety.
The habit that holds it together: three-way reconciliation
If you do one thing well, make it the reconciliation, because it is both the control that catches everything else and the record most often missing. The idea is that three separate numbers have to agree, to the penny, on a fixed day every month.
The states describe the same exercise in two halves. Washington requires the check register balance to be reconciled to the bank statement balance, and separately requires the check register balance to be reconciled to the combined total of all client ledger records, as often as bank statements are generated or at least quarterly. Florida requires a monthly bank reconciliation disclosing the balance per bank, deposits in transit and outstanding checks identified by date and check number, plus a monthly comparison between the reconciled account totals and the total of the client ledger cards, “together with specific descriptions of any differences between the 2 totals and reasons for these differences.” Florida also requires an annual list of every client’s unexpended balance.
Where the rules differ on frequency, take the stricter reading and do it monthly. A quarterly cycle means an error can live for ninety days, and the accumulated activity you have to search through when the numbers disagree grows with the interval. Monthly is also simply easier, because the month you are reconciling is the month you remember.
When the three numbers do not agree, the difference itself usually tells you where to look. The pattern is consistent enough to be worth keeping next to the account.
| What you see | What it usually means | Where to look first |
|---|---|---|
| Bank balance is higher than the client ledger total | An earned fee was billed but never transferred out, or a deposit was posted twice | The ledgers for matters you billed in the period, and the deposits against the bank’s record |
| Client ledger total is higher than the bank balance | A disbursement cleared the bank but was never posted to a ledger, or a check was written against funds that had not cleared | The bank’s cleared items against your register, in date order |
| One client ledger shows a negative balance | That client’s costs were paid with another client’s money, which is the violation the rules treat most seriously | The single disbursement that took the ledger below zero, and every entry after it |
| Bank and book balances agree, but the ledgers do not total to either | A receipt or disbursement was posted to the wrong client | Both ledgers on the date of the entry, matched to the check memo or deposit slip |
| A ledger has sat unchanged at a small positive balance for months | Funds that should have been delivered or refunded when the matter closed | The closing file, the final bill, and the last accounting you sent that client |
None of these are exotic. Each one is an ordinary error that a monthly check surfaces in minutes and that a missed check turns into a year of unwinding. Keep the completed reconciliation, because it is a required record in its own right, and because the copy you kept is what lets you show the date a problem started.
Building the system into your firm
Trust accounting is not really an accounting topic. It is an operations topic, and it sits with your fee agreements, your billing calendar and your file-closing routine rather than off in a drawer marked compliance. The firms that stay clean tend to do the same handful of things: open the account correctly and label it, keep a per-client ledger from the first deposit, bill before any fee transfer, reconcile on a fixed day each month and save the result, and close every matter to a zero balance with a written accounting. What makes that list work is not discipline in the abstract but the fact that each item is attached to something the firm already does. The ledger opens when the engagement opens. The transfer follows the invoice you were sending anyway. The reconciliation lands on a fixed date next to the other month-end tasks, and the zero balance is the last line of the file-closing checklist rather than a separate project.
It also connects directly to how money arrives in the first place. The way a retainer is structured determines what lands in trust and what does not, which is covered in our guide to how attorney retainers work. The software you choose either produces these records or leaves you assembling them by hand, which is one of the questions worth asking before a demo rather than after, and is covered in how to choose law practice management software. If you want to see where all of this sits in the larger picture of running a firm as a set of connected systems, our guide to how to run a law firm is the place to start, the Spine program teaches finance and operations as two of its seven systems, and you can score your own firm across all of them in about five minutes.
Frequently asked questions
Lawyer trust accounting is the practice of holding client and third-party money in a separate bank account and keeping records that show, at any moment, how much of the balance belongs to each person. It is governed by two rules in most states: a safekeeping rule, usually numbered 1.15, which sets the duties, and a recordkeeping rule that lists the specific records you must keep and for how long.
An IOLTA account is a type of client trust account. It pools client balances that are small or held briefly into one account so the interest can fund civil legal aid, instead of being consumed by bank fees. Funds that would produce a positive net return for the client generally go into a separate interest-bearing account for that client, with the interest paid to the client. Washington’s rule sets out the three factors that decide which account applies.
Washington lists nine categories: a check register for each account, individual client ledgers, fee and cost agreements, statements and accountings sent to clients, copies of bills rendered, supporting documents for every disbursement, bank statements and deposit slips and cancelled checks, copies of every reconciliation, and the financially relevant portions of client files. They may be electronic or manual and must be kept at least seven years after the events they record. Florida requires eight categories kept six years after the representation ends. Check your own state’s list, because the details differ.
It depends on the state. Florida requires monthly reconciliations plus a monthly comparison of the reconciled account totals against the total of the client ledgers. Washington requires reconciliation as often as bank statements are generated, or at least quarterly. Monthly is the safer routine in either case, because it keeps the search window short when the numbers disagree.
It is a check that three numbers agree: the bank statement balance, your adjusted book balance for the trust account, and the sum of all individual client ledger balances. If the three do not match, there is an error to find before you make any further disbursement from the account. Keeping the completed reconciliation is itself a required record in states such as Washington.
Only in narrow situations that the rules name. Both Washington and Florida allow a lawyer to keep enough of their own funds in the account to cover the bank’s charges on it, and no more. Washington also permits funds necessary to restore appropriate balances. Florida permits a deposit to replenish a shortage, but requires the lawyer to notify the bar’s lawyer regulation department immediately of the shortage, its cause, and the amount deposited.
After the fee is actually earned and after the client has been told. Washington permits withdrawal of earned fees only after giving reasonable notice of the intent to withdraw, through a billing statement or other document. In practice that means the invoice goes out first and the transfer follows, never the reverse, and the ledger entry should reference the invoice that authorized it.
The bank reports it. Washington requires the financial institution to report any properly payable instrument presented against insufficient funds whether or not it is honored, within five banking days, and requires the lawyer to promptly notify disciplinary counsel with a full explanation of the cause. Florida lists a returned trust check as cause for the Bar to order an audit, and that audit is at the lawyer’s expense if it shows the records were not in substantial compliance.
Yes. Most states have adopted a version of the safekeeping rule, but the numbering, the required records, retention periods, reconciliation frequency and reporting obligations all differ, and IOLTA participation rules vary as well. The state examples in this article illustrate the shape of the requirements rather than state your own. Confirm the current text with your state bar or high court before you set up or change how you handle client funds.
