Starting a law firm comes with a long list of administrative tasks. You may need to form a business entity, obtain insurance, select legal software, open an operating account, and establish procedures for billing and expenses.
Opening an Interest on Lawyers’ Trust Account, commonly called an IOLTA, may feel like one more item on that list, particularly when you do not expect to hold client funds immediately.
But an IOLTA is not an ordinary business bank account.
“Opening an IOLTA may seem like a formality when starting a law firm, especially if you do not expect to use it right away. In reality, it marks the beginning of a career-long responsibility that goes beyond the obvious fiduciary duty of holding client funds.”
— Marc Pamatian of Chief Bookkeeping Officer
An IOLTA is a fiduciary account used to hold funds belonging to clients or other persons. Opening the account correctly is only the beginning. The lawyer must also notify the financial institution, register the account with the State Bar of California, maintain the required records, and supervise the account on an ongoing basis.
What Is an IOLTA?
An IOLTA is a pooled client trust account used for entrusted funds that are nominal in amount or expected to be held for a relatively short period.
Instead of allocating the interest to each individual client, the financial institution remits the interest generated by the pooled account to the State Bar’s IOLTA program. Funds that are larger than nominal or will be held for a longer period generally should be deposited into an individual interest-bearing, non-IOLTA trust account for the applicable client.
Depending on the nature of the law practice, an IOLTA may be used to hold:
- Settlement proceeds;
- Advance cost deposits;
- Advance fees that must be held in trust;
- Funds payable to medical providers or lienholders;
- Disputed funds; and
- Other money held for a client or third party.
The underlying principle is straightforward: money belonging to a client or another person must not be treated as law firm operating funds.
Do Not Wait Until the First Client Deposit
A new lawyer may open an IOLTA without expecting to use it immediately. That does not make the account unimportant.
The trust-account system should be established before the first client deposit arrives. Waiting until the firm is already holding entrusted funds can lead to a rushed bank setup, missing client ledgers, incomplete documentation, and confusion over who is responsible for the account.
The lawyer should understand the account-opening process, recordkeeping system, and monthly review procedure before money begins moving through the IOLTA.
Step One: Select an IOLTA-Eligible Financial Institution
A California lawyer cannot establish an IOLTA at just any bank or credit union. The account must be opened at a financial institution eligible to participate in California’s IOLTA program.
The State Bar maintains a current list of eligible institutions. A lawyer should confirm that the selected bank or credit union appears on that list before beginning the account-opening process.
The State Bar also identifies Leadership Financial Institutions. These institutions provide increased interest without fees to maximize the funds available for civil legal aid. Selecting a Leadership Financial Institution is not required, but it may be worth considering when comparing banking options.
The account should be designated as a fiduciary account in the name of the attorney or law firm. Its title should clearly identify it as a trust account.
For example:
Smith Law Group Client Trust Account
or
Smith Law Group IOLTA Trust Account
Step Two: Identify the Designated Licensee
Each California client trust account must have a designated licensee associated with it.
For a solo practice, the solo attorney is the designated licensee. A law firm with two or more California lawyers must select a designated licensee for each trust account.
The designated licensee must be a primary account holder or signatory and is responsible for performing or supervising the account’s monthly reconciliation. One lawyer may serve as the designated licensee for more than one account. Designating that lawyer does not relieve the firm’s other lawyers of their own professional responsibilities.
If the designated licensee becomes inactive, becomes ineligible to practice law, or leaves the firm, the account must be closed or a replacement designated licensee must be assigned within the applicable 30-day period. A new notice must then be served on the financial institution.
Step Three: Complete the Official State Bar Notice
Telling a banker that you want to open an IOLTA is not the entire notification process.
Beginning January 1, 2026, a lawyer establishing a new trust account must complete the State Bar’s official:
Notice to Financial Institution to Establish Trust Account and Provide Designated Licensee Name and State Bar Number
The notice identifies the:
- Law firm;
- Designated licensee;
- Designated licensee’s State Bar number;
- Financial institution;
- Trust account name;
- Trust account number; and
- Contact information associated with the account.
A separate form must be completed for each applicable trust account. The form can be used to open a new IOLTA or non-IOLTA account or to update the account-holder information for an existing trust account.
Step Four: Serve the Notice on the Financial Institution
Completing the State Bar notice and handing it to the employee opening the account is not, by itself, the full process.
The completed form must be served on the financial institution pursuant to California Code of Civil Procedure section 684.115. The lawyer must also take a copy to the financial institution’s branch when opening the account or updating its registration information.
Financial institutions with more than nine California branches are generally required to designate one or more central locations for service of legal process. Institutions with nine or fewer branches may voluntarily designate a central location. The California Department of Financial Protection and Innovation maintains the applicable service-location information.
A practical process is:
- Complete one State Bar notice for each trust account.
- Determine the financial institution’s appropriate location for service.
- Serve the notice pursuant to Code of Civil Procedure section 684.115.
- Take an additional copy to the local branch.
- Retain a copy of the completed notice.
- Preserve documentation showing when, where, and how it was delivered.
The completed form and delivery documentation should become part of the firm’s permanent IOLTA setup records.
Accounts opened before January 1, 2026
For trust accounts that existed before January 1, 2026, the deadline to serve the notice was July 1, 2026.
A lawyer responsible for an existing account who did not complete that process should address the omission promptly. New trust accounts opened on or after January 1, 2026, are subject to the notice requirement when established.
Step Five: Confirm That the Bank Opened the Account Correctly
Do not assume the account was established correctly simply because the banker described it as an IOLTA.
California IOLTA accounts must bear the State Bar of California’s taxpayer identification number. This allows the interest or dividends generated by the account to be paid to the State Bar’s IOLTA program rather than attributed to the lawyer, law firm, or an individual client.
Before depositing client funds, confirm that:
- The account title clearly identifies it as a trust or fiduciary account;
- The account is classified as a California IOLTA;
- The State Bar’s taxpayer identification number is associated with it;
- The designated licensee is an account holder or signatory;
- Interest will be remitted to the State Bar;
- Monthly statements will be available; and
- Canceled checks or check images can be obtained.
Review the account-opening documents carefully and examine the first bank statement. This may reveal titling, taxpayer-identification, mailing-address, or statement-delivery problems that were not apparent during the account-opening appointment.
Step Six: Report the Account to the State Bar
Serving the financial institution does not automatically register the account with the State Bar.
After a trust account is opened, closed, or changed, the lawyer must separately update the account information through My State Bar Profile. The State Bar requires changes to IOLTA information to be reported no later than 30 days after the change.
The information requested may include:
- Account type;
- Financial institution name;
- Routing number;
- Account number;
- Law firm or organization name;
- Date the account was opened;
- State in which the account is maintained; and
- Designated-licensee information.
Lawyers must also complete the applicable annual Client Trust Account Protection Program reporting process. This includes answering the annual reporting questions, registering applicable trust accounts, completing the required self-assessment, and submitting the required certification and declaration.
Step Seven: Establish the Accounting Records Before Receiving Client Money
Opening the bank account does not create the accounting records necessary to manage it.
Before receiving client funds, the firm should establish a trust-account journal, a separate ledger for every client or third party whose funds are held, and a bank-charges ledger when the firm maintains its own limited funds in the IOLTA to cover permissible bank charges.
The trust account journal records the activity and running balance of the IOLTA as a whole. The individual ledgers separately identify the receipts, disbursements, and remaining balance attributable to each client or third party.
Both records are necessary. The journal shows the total amount being held, while the individual ledgers show who owns that money.
The firm should also retain the related:
- Bank statements;
- Canceled-check images;
- Deposit records;
- Settlement statements;
- Invoices;
- Fee agreements;
- Lien documentation;
- Transfer records; and
- Other supporting documentation.
Trust-account records generally must be retained for at least five years after the appropriate distribution of the funds to which the records relate.
Understand the Ongoing Monthly Responsibility
Opening and registering the IOLTA is only the beginning. Once the account is established, the lawyer must maintain the required records and ensure that the account is reconciled and documented each month.
The designated licensee is responsible for performing or supervising that process. A qualified bookkeeper may help maintain the records and prepare the reports, but the lawyer remains responsible for understanding and overseeing the work.
For a detailed explanation of the monthly accounting process, see our guide to IOLTA three-way reconciliation.
What the Financial Institution Does—and Does Not Do
The financial institution maintains the bank account, processes transactions, produces statements, and remits the IOLTA interest to the State Bar.
It does not:
- Create the law firm’s individual client ledgers;
- Determine how much belongs to each client;
- Verify whether the firm has disbursed too much for a particular matter;
- Investigate unidentified client funds;
- Review settlement distributions; or
- Supervise the firm’s trust-account bookkeeping.
Those responsibilities remain with the lawyer and law firm.
A New California Lawyer’s IOLTA Checklist
Before receiving client funds:
- Determine whether the funds belong in an IOLTA or a separate non-IOLTA trust account.
- Select an IOLTA-eligible financial institution.
- Identify the designated licensee.

- Serve the notice pursuant to Code of Civil Procedure section 684.115.
- Take a copy of the notice to the local branch.
- Retain the completed notice and evidence of delivery.
- Confirm that the account is properly titled and classified.
- Confirm that the State Bar’s taxpayer identification number is attached.
- Report the account to the State Bar within 30 days.
- Establish the trust account journal and client-ledger system.
- Create a procedure for monthly reconciliation and attorney review.
- Preserve the accounting records and supporting documentation.
The Bottom Line
Opening an IOLTA is not merely a preliminary banking task.
It begins an ongoing process of identifying entrusted funds, maintaining client-level records, supervising account activity, updating the State Bar, and documenting the firm’s monthly review.
Getting the process right at the beginning gives a new law firm a reliable foundation before the first client deposit arrives. It is much easier to maintain accurate trust records from the start than to reconstruct them months or years later.
