• California requires a mandatory waiting period of at least 15 days after filing before the court can schedule a hearing, and notice must be given to all heirs and beneficiaries.
• In a high-volume jurisdiction like Alameda County, the court's probate calendar is typically booked several weeks out, and anticipate scheduling delays for the initial hearing.

California's small estate threshold — $208,850 (adjusted annually for inflation) — is among the highest in the nation, making the small estate affidavit a widely used alternative to formal probate in Alameda County, ranked 7th of the state's 58 counties. Under California Probate Code § 13100, heirs can use a declaration to collect real property valued under $75,000 per parcel, and § 13100 affidavits to collect personal property without opening a probate case.

The affidavit cannot be used until 40 days after the decedent's death.

In a high-value jurisdiction like Alameda County, many estates exceed the small estate threshold. However, evaluate whether non-probate transfer mechanisms — such as revocable living trusts, which are extremely common in California — have already removed assets from the probate estate.

California's widespread use of living trusts means that the "probate estate" is often much smaller than the decedent's total wealth.
