Trust Administration After Both Parents Die in California
Losing both parents is one of life's most profound experiences. If they had a joint living trust—as many married couples do—you may now be facing trust administration for the first time. The legal responsibilities can feel overwhelming when you're already grieving.
This guide explains what happens and what you need to do when the surviving parent passes away and you become responsible for their trust.
How Joint Trusts Work After Both Deaths
Most married couples create a single joint trust that operates in stages:
While Both Spouses Are Alive
Both parents serve as trustees and can change the trust anytime.
After the First Parent Dies
Typically, the surviving parent:
- Continues as sole trustee
- Has access to all trust assets
- May be able to modify their share of the trust
- The deceased spouse's share may become irrevocable
After the Second Parent Dies
The trust becomes fully irrevocable, and distribution to children/beneficiaries begins.
This is when full trust administration happens.
Understanding Your Role
If You're Named as Successor Trustee
You are now responsible for:
- Managing all trust assets
- Paying debts and final expenses
- Filing tax returns
- Distributing assets to beneficiaries
Your authority begins immediately upon your surviving parent's death. No court appointment is needed.
If You're Named as Beneficiary (But Not Trustee)
Someone else handles administration. Your rights include:
- Receiving notice about the trust
- Requesting trust information
- Receiving accountings
- Receiving your distribution
You're entitled to be kept informed, but you're not responsible for administration.
If You're Both Trustee and Beneficiary
This is common. You manage the trust AND receive assets from it. See our article on this topic for guidance on managing potential conflicts.
What's Different After Both Parents Die
The Trust Becomes Fully Irrevocable
After the first parent died, part of the trust may have remained revocable (changeable) by the surviving parent. Now, everything is permanent. No one can change the trust terms.
All Assets Are Now Subject to Distribution
Assets that the surviving parent used during their lifetime now pass to the ultimate beneficiaries—typically children and grandchildren.
Sub-Trusts May Be Created
Many trusts create separate sub-trusts after both parents die:
- Children's trusts (for minor or young adult children)
- Special needs trusts (for disabled beneficiaries)
- Grandchildren's trusts
- Generation-skipping trusts
Review your parents' trust carefully to see if sub-trusts are required.
Different Tax Treatment
After both parents die:
- The full trust may now owe income tax on accumulated income
- Estate tax may apply if the combined estate exceeds $13.61 million
- Stepped-up basis applies to assets again (for the surviving parent's share)
Step-by-Step: What to Do Now
Week 1: Immediate Steps

9. Send the 60-Day Notice
Within 60 days, send written notice to:

The 120-day period must expire before final distributions.

- Trust income tax return
15. Distribute to Beneficiaries
After the contest period expires and taxes/debts are paid:

- Deliver personal property
16. Create Sub-Trusts (If Required)
If the trust requires creating separate trusts for minors or others, fund and establish those trusts.
Final Steps: Close Administration

Document everything that happened during administration.
18. Get Receipts from Beneficiaries
Have each beneficiary sign acknowledging what they received.
19. File Final Tax Returns
File the trust's final income tax return.

Keep all records for at least 5-7 years.
Special Situations
If Your Parents Lived in Different States
If parents owned property in multiple states:
- The trust should cover all properties
- You may need to work with attorneys in other states
- Recording requirements vary by state
- Tax rules may differ
If the Trust Wasn't Fully Funded
Sometimes parents don't transfer all assets to the trust. Assets outside the trust may require:
- Small estate procedures
- Probate
- Beneficiary designations
If There Are Minor Children (Your Siblings)
If you have minor siblings who are beneficiaries:
- Their shares likely stay in trust until they reach a specified age
- You may be trustee of their sub-trusts
- You have ongoing management duties
- Annual accountings may be required
If a Beneficiary Has Special Needs
If a sibling has disabilities and receives government benefits:
- Their share likely goes to a special needs trust
- Distributions must not disqualify them from benefits
- Special rules apply
- Consider consulting a special needs attorney
If There Are Family Conflicts
If siblings don't get along:
- Document everything meticulously
- Communicate in writing
- Consider using a professional trustee
- Mediation may help
- An attorney can provide buffer and guidance
Emotional Considerations
Administering your parents' trust while grieving is emotionally exhausting.
Give Yourself Grace
- You don't have to do everything immediately
- It's okay to ask for help
- Taking care of yourself is important
Communicate with Siblings
- Keep everyone informed
- Don't make major decisions alone
- Address concerns before they become conflicts
Manage Expectations
- Administration takes time (6-12 months typically)
- Not everything will go smoothly
- Some frustration is normal
Seek Support
- Lean on family and friends
- Consider grief counseling
- Professional help (attorney, CPA) reduces stress
The Final Gift
Administering your parents' trust is, in a way, a final act of love. You're honoring their wishes and ensuring their legacy passes to the people they chose.
It's hard work during an already difficult time. But completing this process properly honors everything your parents built and planned for.
