If your trustee is mixing trust funds with personal money, you may be a victim of commingling, a form of trustee misconduct that can constitute self-dealing under California law.
At The Grossman Law Firm, we often speak with beneficiaries who are unsure whether what they are seeing is actually a legal issue. This guide explains what commingling looks like, why it matters, and what you should do next.
What Is Commingling?
Commingling occurs when a trustee fails to keep trust assets separate from their own personal assets.
Under California law, trustees must maintain clear separation between:
- Trust bank accounts
- Personal accounts
- Investments
- Property ownership
Mixing funds is not allowed–even if the trustee claims it was done for convenience.
Why This Is a Problem
Trustees have a fiduciary duty to act in the best interests of the beneficiaries. That includes keeping accurate records and maintaining transparency.
When funds are commingled:
- It becomes difficult to track where the money went.
- Financial records may become incomplete or unreliable.
- The trustee may gain access to trust funds for personal use.
California courts take this seriously. Even without obvious theft, commingling can constitute a breach of fiduciary duty and may lead to removal of the trustee, financial liability, and damages for losses to the trust.
Common Warning Signs
Beneficiaries often notice commingling through small inconsistencies.
Watch for:
- The trustee refuses to provide bank statements.
- Payments are made from unknown or personal accounts.
- Trust funds are deposited into accounts not labeled as trust accounts.
- Financial reports are vague or missing key details.
- The trustee cannot clearly explain transactions.
If the financial picture feels unclear, that is often the first red flag.
What You Can Do
If you suspect commingling, there are a few immediate steps you can take.
- Request information
Ask the trustee for:
- Account statements
- A formal accounting (Documentation of transactions)
- Document what you see
Keep records of:
- Emails
- Statements
- Missing information
- Inconsistent explanations
- Speak with a litigation attorney who handles these types of cases
In many cases, a court order is required to obtain a formal accounting. At this stage, these issues rarely resolve on their own. A trust litigation attorney can take the necessary legal steps to protect your interests and move the process forward.
- Hire court intervention
If necessary, a probate attorney court can:
- Order a full accounting.
- Require repayment of funds.
- Suspend or remove the trustee.
Why Timing Matters
Commingling cases often require tracing funds and reviewing financial records. The sooner this is done, the easier it is to identify what happened.
Commingling tends to get worse over time.
As more transactions occur:
- Records become harder to reconstruct
- Funds become harder to trace
- Potential losses increase
In many cases, commingling is part of a larger pattern of trustee misconduct.
