Key Takeaways

  • California trustees have a legal duty to manage trust assets with reasonable care and in the best interests of the beneficiaries.
  • A trustee who acts carelessly or fails to fulfill their duties may be liable for negligence or breach of fiduciary duty.
  • Beneficiaries may have the right to seek financial compensation, remove the trustee, or pursue other legal remedies.
  • Acting quickly can help preserve evidence and protect trust assets.

What Is Trustee Negligence?

When someone agrees to serve as a trustee, they take on a legal responsibility to manage the trust with care. That includes protecting trust assets, following the terms of the trust, making prudent financial decisions, and keeping beneficiaries reasonably informed about the trust’s administration.
A trustee may be negligent if they fail to act with the level of care that a reasonably prudent trustee would use under similar circumstances. In other words, a trustee who ignores problems, makes careless decisions, or fails to protect trust assets may be held accountable for the harm those actions cause.
Examples may include:
  • Failing to protect trust assets
  • Ignoring investment responsibilities
  • Missing important tax or legal deadlines
  • Failing to maintain accurate records
  • Allowing trust property to lose value through inaction
Not every mistake amounts to negligence. The question is whether the trustee failed to act with the care California law requires.

When Can You Sue a Trustee?

If a trustee’s carelessness ends up costing the trust or its beneficiaries money, you may have grounds to take legal action.
To succeed, beneficiaries generally must show that:
  • The trustee owed a fiduciary duty.
  • The trustee breached that duty through negligent conduct.
  • The breach caused financial harm.
  • The beneficiaries suffered measurable damages.
At The Grossman Law Firm, Attorney Scott Grossman evaluates trust litigation matters throughout California to determine whether beneficiaries have grounds to pursue legal action.

What Happens If the Trustee Is Found Liable?

If the court determines that a trustee breached their fiduciary duties through negligence, it may order remedies such as:
  • Repaying losses to the trust
  • Returning improperly used trust assets
  • Removing the trustee
  • Ordering a full trust accounting
  • Awarding other relief allowed under California law
Every situation is different, but California courts have the power to hold trustees responsible when their actions harm beneficiaries. If you believe a trustee’s negligence has reduced the value of your inheritance, The Grossman Law Firm can evaluate your situation and explain your legal options.

FAQ

Can I sue a trustee for making a mistake?

Not every mistake amounts to negligence. The trustee’s conduct must fall below the standard of care required under California law and result in financial harm.

Can a trustee be personally liable?

Yes. In some cases, a trustee may be personally responsible for losses caused by negligent conduct or another breach of fiduciary duty.

Should I wait before taking legal action?

Generally, no. Waiting may make it more difficult to gather financial records, preserve evidence, or prevent additional losses to the trust.
