Short answer: A trustee in California is personally on the hook for following the trust’s terms, sending the required notices, filing the trust’s tax returns, and accounting to beneficiaries, and an estate planning attorney’s job in trust administration is to keep the trustee inside those legal lines. California sets no fixed deadline for finishing administration, only a duty to act within a reasonable time under Probate Code § 16000, which is exactly the kind of open-ended standard that gets an unrepresented trustee sued.
What does a trustee actually have to do?
A trustee must administer the trust according to its written terms and the law, full stop. That duty comes from Probate Code § 16000, and it covers everything from paying the decedent’s debts and the trust’s taxes to keeping trust assets separate from the trustee’s own. A trustee also cannot use trust property for personal benefit under Probate Code § 16004, which sounds obvious until a trustee moves into the trust’s rental property “temporarily” or borrows from a trust account to cover a personal expense. Both are breaches of duty even if the trustee intends to pay the money back.
Beneficiaries are entitled to accountings from the trustee under Probate Code §§ 16060 through 16063. That means the trustee has to keep real records of what came into the trust, what went out, and why. A properly funded revocable living trust also lets administration happen privately, outside the court-supervised probate process that applies to assets left in a decedent’s own name.
What deadlines can a trustee not afford to miss?
When a revocable trust becomes irrevocable, which usually happens at the grantor’s death, the trustee must send a formal notice to every beneficiary and legal heir within 60 days, under Probate Code § 16061.7. That notice starts a 120-day window during which anyone who wants to contest the trust has to act. Get the notice wrong, whether it is late, sent to the wrong people, or missing required information, and that clock does not start running, which leaves the trust exposed to a contest long after the trustee assumed the door had closed.
On the tax side, a trust generally has to file a federal Form 1041 and a California Form 541 for any tax year its gross income exceeds $10,000 or its net income exceeds $100. Those thresholds are low enough that almost any trust holding real property or investments will trigger a filing obligation, and missing it creates its own set of problems with the IRS and the Franchise Tax Board.
Why bring in an estate planning attorney instead of handling it alone?
Most trustees are not lawyers, and most are grieving a family member while also being told they are now personally liable for getting a legal process right. An estate planning attorney’s role in trust administration is to translate the trust document and the Probate Code into a checklist: send the § 16061.7 notice correctly and on time, track the 120-day contest window, prepare accountings that will hold up if a beneficiary later demands one, and coordinate the trust’s tax filings with the trustee’s accountant.
None of this requires a law degree in the abstract, but the trustee who skips a step is the one personally exposed. An attorney’s involvement is what turns “I think I did this right” into “I can show exactly what I did and why.”
What happens when a beneficiary disagrees with the trustee?
A beneficiary or other interested party can petition the court under Probate Code § 17200 to compel an accounting, instruct the trustee on how to proceed, or, in serious cases, remove the trustee entirely. This is where having an attorney already involved pays off. A trustee who has kept proper records and followed the notice and accounting requirements has a straightforward answer to a § 17200 petition. A trustee who has not is starting from a deficit before the hearing even happens.
Family disputes over a trust are rarely just about money. They are usually old grievances resurfacing at the worst possible time. An attorney representing the trustee cannot make those grievances disappear, but can keep the administration itself from becoming the thing beneficiaries are fighting about.
How long does administration take, and what does it cost?
A typical uncontested trust administration in California runs about 6 to 18 months. That is a practical range based on how long it actually takes to collect assets, pay debts and taxes, and distribute what is left, not a statutory deadline. Contested administrations, or ones involving real property sales or complicated tax issues, take longer.
Trustee compensation is set by whatever the trust document says. If the trust is silent on the point, the trustee is entitled to reasonable compensation under the circumstances, with no fixed statutory percentage the way probate has for an executor. When Ridley Law is retained for trust administration work that requires extended legal involvement, such as a contested accounting or a beneficiary dispute, the firm generally bills at an hourly rate of $500. Fees are discussed upfront before any work begins, and the firm’s general fee approach is posted on its fees page.

What to do next
If you have just been named trustee, or a family member has died and left you holding a trust document you are not sure how to execute, get the notice and accounting requirements right before you do anything else. A short consultation with an estate planning attorney at the start of trust administration is far cheaper than cleaning up a missed deadline six months in.
