Frequently asked questions

How difficult is it to contest a trust in California?

It depends on the grounds. A claim that an account belongs to the trust, a breach-of-duty claim over transfers, and a challenge to the trust document under section 21380 each have their own procedure and burden of proof. A formal contest by a person served with the trustee's notification must be brought within 120 days of service or 60 days after delivery of the trust terms during that period, whichever is later.

Can a beneficiary demand records about a trust bank account?

Yes. Under Probate Code section 16061, the trustee must provide requested information relevant to the beneficiary's interest on reasonable request, except as section 16069 provides. If the trustee fails to provide it within 60 days after a reasonable written request and the beneficiary has not received it in the preceding six months, the beneficiary may petition under section 17200(b)(7).

What happens if a trustee transfers trust account funds to themselves?

Probate Code section 16004(a) bars a trustee from using trust property for personal profit or in a transaction adverse to the beneficiary, and section 16004(c) presumes a breach when the trustee gains an advantage from a beneficiary. Remedies under section 16420(a) include compelling repayment, a constructive trust and removal. A surcharge under section 16440 is not automatic.

What is a Probate Code section 850 petition and when does it apply to a bank account?

It is the petition, often called a Heggstad petition, used to ask the Superior Court of California to determine that a particular asset belongs to the trust, typically an account the trust described as trust property but that was never retitled in the trust's name before the settlor died.

Can a court remove a trustee who mismanaged a trust account?

Yes. Under Probate Code section 15642, the court may remove a trustee on petition of a settlor, cotrustee or beneficiary under section 17200, on grounds including a breach of trust. While the case is pending, the court may appoint a temporary trustee under section 17206.

Is there a deadline to bring a breach-of-trust claim over a trust account in California?

Yes. Under Probate Code section 16460(a), the claim must be brought within three years after the beneficiary receives an account or written report that adequately discloses it, or, if no such account or report discloses it or none is received, within three years after the beneficiary discovered or reasonably should have discovered the subject of the claim.

Does a no-contest clause prevent a beneficiary from disputing a trust account transfer?

Not always. Under Probate Code section 21311(a), a no contest clause may be enforced only against a direct contest brought without probable cause and, only if the clause expressly says so, a pleading claiming property was not the transferor's or a creditor's claim. Probable cause exists if the facts known at filing would cause a reasonable person to believe there is a reasonable likelihood the relief will be granted after further investigation or discovery.

What if a caregiver or helper was named to receive trust account funds?

A gift to a care custodian of a dependent adult, in an instrument executed while the care custodian provided services or within 90 days before or after, is presumed under Probate Code section 21380 to result from fraud or undue influence. The presumption can be rebutted by clear and convincing evidence. Not every gift to a caregiver or helper falls within it.
