New 2026 California Probate Law Requires Estates to Notify Child Support Agencies
In Short: Assembly Bill 1521, effective January 1, 2026, requires California estate representatives to notify the Department of Child Support Services within 90 days of Letters being issued, if the deceased had a court-ordered child support obligation. Once notified, the agency has four months to file a creditor claim — a claim that must be resolved before heirs receive their inheritance.
Most California heirs have never heard of Assembly Bill 1521. The new law, effective January 1, 2026, added a significant creditor notification requirement to the California probate process — one that could reduce your inheritance if your loved one had an unresolved child support order.
Unresolved child support obligations are more common in estates than most families expect. Prior marriages, children from other relationships, and old court orders that were never formally closed can all create exposure. If the deceased had any of these in their history, the estate now has a legal duty to notify the state — and a four-month window opens for a creditor claim.
What Assembly Bill 1521 Requires
AB 1521 amends California Probate Code Section 9202. For any estate where Letters Testamentary or Letters of Administration are first issued on or after January 1, 2026, the personal representative and estate counsel must notify the Department of Child Support Services (DCSS) if they know — or have reason to believe — the decedent had an outstanding child support obligation under a valid court order.
The notice must be sent within 90 days of Letters being issued. Under the new law, notice can be submitted electronically through the DCSS website in addition to the existing mail option. Once DCSS receives notice, the local child support agency has four months to assert a creditor claim under Probate Code Section 9202(e)(2).
That claim is treated like any other creditor claim in probate — it must be addressed before the estate distributes assets to beneficiaries.
How This Can Reduce Your Inheritance
If DCSS files a valid child support claim, it becomes a priority obligation of the estate. The estate must satisfy that debt before heirs receive anything. Depending on how long the support obligation went unpaid — and interest and penalties can accumulate over years — the impact on the final distribution can be substantial.
For beneficiaries who were unaware of any prior support orders, this can come as a significant surprise late in the probate process. This type of situation is similar to a Medi-Cal creditor claim — both reduce what heirs ultimately receive and both extend the probate timeline.

What Heirs Should Do
If you are a beneficiary in a California probate estate opened after January 1, 2026, and you have any reason to believe the deceased had a child support order — from a divorce, a prior relationship, or any family court proceeding — raise it with the personal representative directly. Ask whether DCSS notice was sent and whether any claim has been received.
You also have the right to review creditor claims filed in the probate case. California probate filings are public record. If a DCSS claim has been submitted, it will appear in the case documents at the superior court.
Working with a probate attorney is the most reliable way to understand how an existing creditor claim affects your specific share and what, if any, grounds exist to challenge or reduce it. You can find a California probate attorney through our California probate attorney directory.
Why This Matters for 2026 Probate Cases Specifically
AB 1521 applies to all estates where Letters are issued on or after January 1, 2026 — which covers the majority of California probate cases opening right now. The practical effect is an additional layer in the creditor claims process. The four-month window DCSS gets after notice means the estate cannot move toward distribution until that window closes or any filed claim is resolved.
On top of California’s already long probate timeline, this is another reason distributions take longer than heirs expect. It compounds with court backlogs, Medi-Cal recovery proceedings, and the general complexity of California estate administration.
Do Not Wait for Creditor Claims to Resolve — Get an Advance Now
Creditor claims extend the time heirs spend waiting. Whether it is a Medi-Cal claim, a child support claim under the new law, or another estate debt, the result is the same: distributions get pushed out.

Frequently Asked Questions
What does Assembly Bill 1521 require in California probate?
AB 1521, effective January 1, 2026, requires personal representatives and estate attorneys to notify the Department of Child Support Services within 90 days of Letters being issued, if the deceased had a known court-ordered child support obligation. Once notified, DCSS has four months to file a creditor claim against the estate.
Does a child support creditor claim take priority over beneficiary distributions?
Yes. Like other creditor claims in California probate, a valid child support claim must be resolved before the estate distributes assets to heirs. If the claim is large, it can significantly reduce what beneficiaries receive.
What if the personal representative does not know about an old child support order?
The law requires notification only if the representative knows or has reason to believe an obligation existed. However, beneficiaries who are aware of prior support orders should raise the issue with the representative directly to make sure the notice duty is properly addressed.
How long does a DCSS creditor claim add to California probate?
Once notified, DCSS has four months to file a claim. Any claim that is filed must then be addressed before distribution, which can extend the total probate timeline considerably — especially if the claim amount is contested.
Can I get a probate advance if there is a child support creditor claim on the estate?
Yes. ProbateLend evaluates advances based on your expected individual inheritance share. Creditor claims against the estate as a whole do not automatically disqualify you, though the advance amount may reflect any reduction in your projected share.
