Over the past few decades, estate values and inheritances in the U.S. have more than doubled, and this upward trend shows no signs of slowing down. In fact, over the next 30 years, American retirees are projected to pass on more than $36 trillion in wealth to their families, friends, charitable organizations, and other beneficiaries, according to a 2021 estate planning report by SeniorLiving. As estates grow larger, the average age of those receiving inheritances has also increased.
With this growing transfer of wealth, managing and accounting for trusts has become more important than ever. In California, where legal and financial standards are strict, it requires close attention to detail and adherence to specific legal requirements. Whether you're a trustee or an attorney, this guide will walk you through the basics and requirements of trust accounting in California to help you navigate trust accounts effectively.
What is Trust Accounting?
Trust accounting is the process of tracking and reporting all financial activities related to client funds held in trust. These funds are kept in a special bank account that is separate from your business or personal accounts and must remain fully traceable. The funds are reserved for a specific purpose in the client’s case and cannot be accessed before that purpose is fulfilled.
In simpler terms, trust accounting involves maintaining a financial record that clearly shows where every dollar in the trust came from and how it is used.
Defining Client Trust Account
A client trust account is a special bank account where a lawyer holds funds on behalf of clients. This account is kept separate from the law firm’s operating funds and cannot be used to pay firm expenses or fees, unless the funds have already been earned and properly transferred.
There are two common types of trust accounts:
- A pooled trust account combines funds from multiple clients into one account. Each client’s portion is carefully tracked in separate records, but the money is physically kept together.
- A separate trust account is an individual account set up for one client only. It keeps that client’s funds entirely apart from others.
This segregation of funds is fundamental to trust accounting and is required by California law. Under Rule 1.15 of the California Rules of Professional Conduct, attorneys must hold client funds in a trust account that is separate from personal and business accounts.
These accounts must be maintained at financial institutions that are insured by the FDIC or a similar entity and must be clearly labeled as “trust account” or with words of similar import.

Who Prepares a Trust Account?
A trustee is often responsible for preparing trust accountings and is expected to act in the best interest of the client they represent. However, given the complexity of trust accounting requirements in California, many individuals seek professional assistance with this task.
You might choose to work with:
- Bookkeepers specializing in trust accounting
- Certified Public Accountants
- Trust administration attorneys
- Trust accounting specialists
Even when you delegate preparation to professionals, remember that as a trustee, you remain accountable for the accuracy and compliance of the trust accounting. It’s essential to work with qualified professionals who understand California’s specific requirements.
Types of Trust Accounts
There are different types of trust accounts used in California, each designed to meet specific requirements and considerations, particularly when it comes to permitted investments and distribution rules.

Some of the most common types are:
- Revocable Living Trust: Also known as a “living trust,” this holds assets that the trustor can change or revoke during their lifetime. It allows the trustor to update their estate plan as needed, manage their assets easily, and avoid the probate process after death.
- Irrevocable Trust: Once created, this account cannot be changed or terminated without the beneficiary’s permission. Irrevocable trusts provide greater protection from creditors and estate taxes because the trustor gives up control of the assets.
- Interest on Lawyer Trust Accounts (IOLTA): An account used by attorneys to hold client funds separately from their own money. It commonly contains retainers or settlement funds, and any interest earned typically supports legal aid programs.
- Special Needs Trust: This type of account is designed to hold money for beneficiaries with disabilities without affecting their eligibility for government benefits. It covers expenses not paid for by public programs, helping maintain the beneficiary's quality of life.
- Charitable Trust: This is an account created to manage and distribute funds for charitable purposes. They allow donors to support nonprofit organizations or causes they care about, often with added tax benefits.
Benefits of Trust Accounting
Trust accounting is more than just legal obligation and bookkeeping. It also offers practical advantages.
- Organized and Clear Financial Records. Trust accounting keeps all financial activities in one place, making it easier to track where the money is going, monitor the trust’s performance, and stay up to date.
- Legal Compliance: It helps ensure you meet state laws and fiduciary duties, protecting you from legal risks or claims of mismanagement.
- Transparent Client Relationships. By providing regular, easy-to-understand financial reports, you give beneficiaries confidence in how the trust is being managed. This transparency builds trust and shows that you’re acting in their best interests.
- Dispute Prevention. Clear and consistent accounting records reduce the chances of confusion. When beneficiaries can see how funds are handled and decisions are made, it lowers the risk of legal disputes.
- Tax Compliance. It supports accurate tax reporting by documenting all transactions properly, making it easier to file tax returns and avoid penalties.
- Informed Decision-Making. When trustees have access to complete financial data, they can make smarter, more confident decisions.

Common Mistakes in Trust Accounting
Commingling Funds
Mixing trust funds with personal or business funds is a serious violation and can lead to legal consequences.
Best Practice: Always keep a separate trust account for client funds and never use it for personal or business expenses.
Delaying Transfers of Earned Fees
Holding onto earned fees in a trust account for too long can create accounting confusion and raise ethical concerns.
Best Practice: Once fees are calculated and invoiced, promptly transfer them to your operating account with proper documentation.
Inadequate Documentation
Failing to maintain detailed records of every transaction affecting the trust can lead to errors and disputes.
Best Practice: Document every transaction with date, amount, purpose, and parties involved. Keep receipts, invoices, and written explanations for unusual transactions. Consider using trust accounting software that maintains an audit trail and generates compliant reports.
Format Errors
California Probate Code sections 1060-1064 specify exact format requirements for trust accountings. Even if you provide an accurate record, but don't conform to the required format, it can lead to rejected accountings and court challenges.
Best Practice: Follow standard trust accounting formats or use accounting templates specifically designed for California trust accountings.
Incomplete or Missing ledgers
Missing client-specific ledgers makes it difficult to track balances and properly manage funds.
Best Practice: Maintain individual ledgers for each client or beneficiary and update them with every transaction.
Neglecting Tax Implications
Trust transactions often have tax consequences that must be properly tracked and reported. Ignoring it can lead to costly penalties or missed deductions.
Best Practice: Track all taxable events and consult a tax professional to ensure accurate reporting.
Failing to Keep Records
Some trustees discard or lose supporting documentation before the statute of limitations expires. Poor recordkeeping can result in noncompliance, disputes, or inability to defend actions if audited.
Best Practice: Implement a record retention system with digital and physical backups that store all trust records securely for at least five years after trust termination.
