1. What is a Trust Account?
A trust account is a separate account that is used to hold client's funds. These funds may include money for retainers, settlements, or other fees. Trust accounts are specifically designed for safekeeping funds belonging to clients.
A trust account is established to ensure that client money is kept separate from the law firm’s operating account. Attorneys may also be responsible for both funds and property of clients when managing trust accounts. Attorneys must properly handle client funds in accordance with legal and ethical standards.
How Do the Different Types of Trust Accounts Fit Into Each State’s Rules & Regulations?
In California, attorneys are required to follow strict trust accounting rules and regulations regarding trust accounts in order to maintain compliance with the State Bar of California. Estate planning attorneys must understand the different types of law firm trust accounts and the state law requirements for each type. Attorneys may be holding funds for clients or other persons, and must choose the appropriate account type based on the amount of money involved and the nature of the funds entrusted to them. Other funds, such as settlement payments, advances for costs, or funds received from third parties, may also need to be deposited in trust accounts. Funds received as advance payment for future services must be deposited into a trust account unless they are a true retainer, which is earned immediately and may be deposited into the operating account. Attorneys are responsible for properly managing all funds entrusted to them by clients or other persons, ensuring compliance with all applicable rules and regulations. Here are some types of law trust accounts and how they fit into California State’s Rules & Regulations.
Types of Trust Accounts
IOLTA (Interest on Lawyers’ Trust Accounts): Used for client funds that are nominal or held for a short period. The interest earned is paid to the State Bar to fund legal aid programs.
Non-IOLTA Trust Accounts: Used for larger or longer-term client funds, where interest is paid to the client.

Choosing a Financial Institution for Your Trust Account
Selecting the right financial institution for your client trust account is a foundational step in safeguarding client funds and ensuring compliance with California law. Under Rule 1.15 of the California Rules of Professional Conduct, attorneys are required to hold client funds in a separate trust account, distinct from the law firm’s operating or personal accounts. When evaluating potential banks or credit unions, California attorneys should prioritize institutions with a strong reputation for handling lawyers trust accounts and a clear understanding of the unique requirements for client trust accounts.
The State Bar of California maintains a list of eligible financial institutions that are approved to offer Interest on Lawyers’ Trust Accounts (IOLTA). These institutions meet specific criteria set by the State Bar, ensuring that your client trust account will be managed in accordance with professional conduct standards. IOLTA accounts are particularly useful for holding nominal or short-term client funds, as the interest earned supports statewide legal aid initiatives.
