Most people who become a successor trustee never expected to have the job.

A parent dies. A spouse passes away. A loved one becomes incapacitated. Suddenly, you are handed a trust document and told that you are now responsible for carrying out someone else’s wishes, managing assets, handling paperwork, and dealing with beneficiaries. Many successor trustees assume the role is straightforward. In reality, California law places significant responsibilities on trustees, and even well-intentioned mistakes can lead to family conflict, financial losses, or personal liability. If you have recently become a successor trustee, here are seven of the most common mistakes to avoid.

1. Waiting Too Long to Take Action

   Many trustees are grieving and understandably overwhelmed. As a result, they sometimes delay important tasks for months.While there is no requirement to complete everything immediately, certain responsibilities should be addressed promptly, including:

   • Securing trust assets
   • Obtaining death certificates
   • Identifying trust property
   • Notifying financial institutions
   • Reviewing insurance coverage

   Delays can create unnecessary complications and may frustrate beneficiaries who are waiting for information.

2. Failing to Notify Beneficiaries

   California law generally requires trustees to provide formal notice to beneficiaries and heirs when a trust becomes irrevocable after the trustmaker’s death. Some trustees avoid these conversations because they fear conflict or difficult questions. Unfortunately, failing to provide proper notice can create legal problems and may extend the period during which the trust can be challenged.

   Transparency early in the process often prevents larger disputes later.

3. Mixing Trust Funds With Personal Funds

   One of the most serious mistakes a trustee can make is commingling assets. Trust property should never be deposited into personal bank accounts or mixed with personal funds, even temporarily. Instead, trustees should:

   • Establish appropriate trust accounts
   • Keep detailed records
   • Maintain a clear separation between personal and trust assets

   Even innocent accounting mistakes can raise concerns among beneficiaries.

4. Paying Themselves Without Understanding Trustee Compensation Rules

   Many trustees are surprised to learn that they may be entitled to compensation for their work. Others make the opposite mistake and begin taking fees without understanding what is reasonable under California law. Trustee compensation depends on several factors, including:

   • The trust terms
   • The complexity of administration
   • The amount of work performed
   • California fiduciary standards

   Taking excessive fees or failing to document work performed can trigger disputes and beneficiary objections.

5. Selling Assets Too Quickly—or Not Quickly Enough

   Trustees often face difficult decisions involving real estate, investments, and personal property. Some trustees rush to sell everything immediately after a death. Others delay necessary decisions because they are uncertain about their authority.

   Every trust is different. The trustee’s duty is not simply to preserve assets or liquidate assets. The duty is to act prudently and in the best interests of the beneficiaries while following the trust’s instructions.

   Before making major decisions involving trust property, it is often wise to seek legal and tax guidance.

6. Failing to Keep Accurate Records

   A trustee’s best protection is thorough documentation. Beneficiaries have the right to understand how trust assets are being managed. If questions arise, the trustee should be able to show:

   • Bank statements
   • Receipts
   • Asset valuations
   • Tax filings
   • Distribution records
   • Correspondence related to trust decisions

   Poor recordkeeping can quickly create suspicion, even when the trustee has acted appropriately.

7. Distributing Assets Before All Issues Are Resolved

   Beneficiaries are often eager to receive their inheritance, and trustees may feel pressure to distribute assets quickly. However, distributing property too soon can create significant risks. Before making final distributions, trustees should confirm:

   • Debts have been addressed
   • Taxes have been considered
   • Assets have been properly valued
   • Trust administration requirements have been satisfied
   • Potential disputes have been resolved

   Once funds have been distributed, recovering them can be difficult if unexpected liabilities arise.

Being a Trustee Is More Than an Honor—It Is a Legal Responsibility

Many people view being named as a successor trustee as a sign of trust and confidence from a loved one. While that is certainly true, it is also a role that carries significant legal responsibilities. The good news is that trustees do not have to navigate the process alone. An experienced California trust administration attorney can help ensure that legal requirements are met, beneficiaries receive appropriate information, assets are properly managed, and costly mistakes are avoided.
