Being named successor trustee of a parent’s or relative’s living trust usually feels like an honor at the time the trust is signed. The job itself arrives much later, often in the middle of grief, and it comes with legal duties that most people have never had to think about. A successor trustee manages someone else’s property for the benefit of others, and California law holds that person to a high standard while doing it.
Most trust administrations go smoothly, especially when the trust was well drafted and the family gets along. The ones that run into trouble tend to stumble over the same handful of issues: missed notice deadlines, mixing trust money with personal money, poor communication with beneficiaries, and property tax consequences that nobody saw coming.

The First Weeks After a Death
A successor trustee’s authority generally begins when the person who created the trust dies or becomes incapacitated, depending on how the trust is written. The first tasks are practical. The trustee locates the original trust document and any amendments, secures the home and other property, collects mail, and obtains multiple certified copies of the death certificate. Financial institutions typically ask for a copy of the trust or a certification of trust before they will let the successor trustee take over accounts.
Once the person who created a revocable trust dies, the trust usually becomes irrevocable and is treated as a separate taxpayer. The trustee generally needs to obtain a new taxpayer identification number for the trust and open trust accounts under it. Families who meet with Barr & Douds or another estate practice at this stage are often told that keeping trust funds in their own accounts, separate from the trustee’s personal money, is one of the simplest ways to avoid later disputes.
Funny thing is, the house often generates the most work even when it isn’t the most valuable asset. Utilities, insurance, property taxes, maintenance, and decisions about whether a family member can live there all fall on the trustee. Many homeowner’s policies also need to be updated or replaced once a property is vacant, since standard coverage may be limited for empty homes.
The Notice Requirement and the Contest Window
California requires a successor trustee to send a formal notice to every beneficiary of the trust and to the deceased person’s legal heirs within 60 days after the trust becomes irrevocable because of a death, or within 60 days after the trustee takes office if that happens later. The notice must include specific information, such as the trustee’s name and address, the location of the principal place of administration, and a statement that recipients are entitled to a copy of the trust’s terms.
The notice also starts an important clock. A person who receives it generally has 120 days from the date it was served, or 60 days from the date a copy of the trust was mailed after being requested, whichever is later, to bring an action contesting the trust. If the notice is never sent, that window doesn’t close, and a challenge could surface much later. Detailed explanations of this step, like those at https://www.barrattorneys.com/practice-areas/trust-administration/, tend to emphasize that a trustee who fails to send proper notice can also be held responsible for damages caused by the failure.
Who Counts as an Heir
The notice must go to legal heirs even if they receive nothing under the trust. An estranged child, a child from a prior relationship, or other relatives who would inherit if there were no trust are all entitled to it. Leaving someone off because the family doesn’t want them involved is a common and avoidable mistake.
Core Duties Under California Law
California imposes several duties on trustees. The duty of loyalty requires the trustee to act solely in the interest of the beneficiaries, which means no self-dealing, such as buying trust property at a discount or lending trust money to oneself. The duty of impartiality requires treating all beneficiaries fairly according to the trust’s terms, even when the trustee is also a beneficiary. The trustee must also manage and invest the assets prudently, keep accurate records, and keep beneficiaries reasonably informed about the administration.
Here’s the kicker though: many trustee disputes come down to communication rather than wrongdoing. Beneficiaries who hear nothing for months tend to assume the worst. A trustee who sends regular updates, explains delays, and provides an accounting showing what came in, what was paid, and what remains usually avoids the suspicion that can turn into a petition in probate court.
Trustees are generally entitled to reasonable compensation for their work unless the trust says otherwise. Family members often decline compensation, but those handling a complex administration over many months may reasonably accept it. Keeping a record of time spent helps support any fee that is taken.
Property Taxes and Real Estate
Real estate held in the trust raises some of the most consequential questions. Since Proposition 19 took effect in 2021, the rules for passing property from parents to children without a full property tax reassessment have narrowed considerably. The exclusion now generally applies only to a family home that the child uses as their own primary residence after the transfer, and even then it is limited to a portion of the home’s value. Rental properties and second homes passing to children are typically reassessed at current market value.
The trustee usually needs to file a change in ownership statement with the county assessor within a set period after the death, and claims for any available exclusion have their own deadlines. A significant property tax increase can change the family’s plans for a house, so these questions are best addressed before deciding whether to sell, rent, or distribute it.
Speaking of decisions, the trustee also needs to consider income taxes, any final personal tax returns for the deceased person, and potential estate tax issues for larger estates. Holding back a reserve for taxes and final expenses before making distributions protects the trustee from paying out money that will later be needed.
Lessons for the Trustee’s Own Planning
People who have served as successor trustee often come away with a clearer sense of what they want in their own estate plans. They notice which instructions were helpful, which assets were never transferred into the trust, and where vague language created uncertainty. Many decide to update their own documents afterward, and a conversation with a pleasanton estate planning attorney or a planner nearer home frequently focuses on exactly those details: confirming that real estate and accounts are titled correctly, choosing a successor trustee who is organized and trusted by the whole family, and leaving written guidance about personal property that tends to cause the most friction.
Those reviews also tend to cover beneficiary designations on retirement accounts and life insurance, which pass outside the trust and override it if they name someone else.
A Job That Rewards Patience
Trust administration rarely moves as quickly as beneficiaries hope. Accounts take time to retitle, property takes time to sell, and tax questions don’t always have quick answers. A successor trustee who works methodically, keeps careful records, and explains each step to the family is doing exactly what the role requires. That steady approach often matters as much to the family’s relationships afterward as the final distribution itself.
