Will Filing Deadline
The Rule
The person holding a will must file it with the Superior Court within 30 days after learning of the death (Probate Code 8200).
What "Filing" Means
File the original will with the court clerk in the county where the decedent lived. This is required even if you do not plan to open probate.
Consequence of Missing
Failing to deliver the will is a misdemeanor. More importantly, it can expose you to civil liability if beneficiaries are harmed.
Creditor Notice Deadlines
Mail Notice to Known Creditors
Deadline: 30 days after receiving Letters Testamentary
Mail Form DE-157 to every creditor you know about or can reasonably identify. This includes:
- Credit card companies
- Medical providers
- Mortgage lenders
- Anyone who sent a bill
Publish Notice to Unknown Creditors
Deadline: Promptly after appointment
Publish the Notice of Petition to Administer Estate in a newspaper of general circulation. Publish once per week for three consecutive weeks.
Consequence of Missing
If you fail to notify known creditors properly, they may have extended time to file claims, even beyond the four-month period.
Inventory and Appraisal
The Rule
File the Inventory and Appraisal within 4 months of receiving Letters Testamentary or Letters of Administration.
What It Requires
List all estate assets with values as of the date of death. Use the probate referee for assets requiring appraisal.
Consequence of Missing
The court can:
- Issue sanctions
- Remove you as personal representative
- Hold you personally liable for losses
Getting an Extension
You can petition for an extension before the deadline passes if you have good cause (for example, waiting for an appraisal).
Creditor Claims Period
The Rule
The creditor claims period lasts 4 months from the first publication of the Notice of Petition to Administer Estate.
Why It Cannot Be Shortened
This is a statutory minimum. No agreement or court order can reduce it. This is one reason California probate takes at least 6-8 months minimum.
The One-Year Absolute Deadline
No creditor claim can be filed more than one year after death, regardless of notice issues.
Responding to Creditor Claims
The Rule
When you receive a creditor claim, you must respond within 30 days.
Your Options
- Allow the claim
- Allow in part
- Reject the claim
Consequence of Missing
If you fail to respond within 30 days, the claim is deemed allowed. You cannot later reject it.
Tax Return Deadlines
Decedent's Final Income Tax Return
Federal (Form 1040): April 15 of the year following death California (Form 540): Same deadline
If the decedent died on July 15, 2025, the final return is due April 15, 2026.
Estate Income Tax Returns
If the estate earns income during administration (interest, rent, dividends), file:
- Federal (Form 1041): April 15 of following year
- California (Form 541): Same deadline
Federal Estate Tax Return
Form 706: Due 9 months after death (if required)
Only required if the gross estate exceeds the federal exclusion amount ($15 million in 2026). A 6-month extension is available.
Consequence of Missing
IRS penalties and interest. Potential personal liability for the personal representative.
Notice to Beneficiaries
Notice of Administration
After Letters are issued, notify heirs and beneficiaries of the probate proceeding.
Deadline: Within a reasonable time (30 days is common practice)
Notice for Trust Beneficiaries
If the decedent had a trust, beneficiaries must be notified within 60 days of the trustee assuming office.
Family Allowance
Requesting Family Allowance
If the surviving spouse or minor children need support during probate, petition for family allowance.
Deadline: Can be filed anytime during administration, but sooner is better for families needing support.
Final Distribution
Petition for Final Distribution
After debts are paid and the creditor period closes, file the Petition for Final Distribution.
Deadline: No specific deadline, but courts expect reasonable progress. Excessive delay can result in court intervention.
Calendar Your Deadlines
Create a timeline when probate opens:
| Event | Deadline |
|---|---|
| Letters issued | Day 0 |
| Mail creditor notice | Day 30 |
| Publish notice | Week 1-3 |
| 4-month creditor period ends | ~Day 120 |
| File inventory | Day 120 |
| Final tax return | April 15 following death year |
Common Mistakes
Forgetting the Will Filing
Many families do not realize the will must be filed with the court even without opening probate.
Missing the Inventory Deadline
The 4-month inventory deadline sneaks up. Calendar it immediately when Letters are issued.
Not Mailing Creditor Notice
Mailing notice to known creditors is easy to overlook. Review bank statements and mail to identify who to notify.
Ignoring Tax Deadlines
The decedent's final return is still due. The estate may also need its own return.
