King County · six questions

Some states file with the county court; others never go to court — the affidavit goes straight to the bank or DMV. The county decides the office and the fee.

3 · Was there a will?

Bank accounts, vehicles, final paychecks, personal property. Leave out joint accounts, accounts with a named beneficiary, and life insurance — those pass without probate anyway.

5 · Did they own real estate other than the home they lived in?

Most states make you wait 10–45 days before the affidavit can be signed or filed.

Has anyone already opened a probate case?

King County procedure

  1. Certified death certificates from Washington vital records or the county registrar — five or more.
  2. Inventory everything in the person's sole name; stop if the total is over $100,000.
  3. Wait 40 days — the affidavit cannot be presented earlier.
  4. Complete the Washington form — Notarized; a copy must be mailed to the Department of Social and Health Services (Office of Financial Recovery) 10 days before it's presented, and to every other heir.
  5. Present it to each holder — $0; notary ≈ $10. Bring a certified death certificate for each.
  6. Collect, pay debts, distribute — keep every receipt; the affiant is liable up to the amount collected.

What makes Washington different

Washington adds a step nobody expects: a copy of the affidavit has to go to DSHS Office of Financial Recovery at least 10 days before you use it, so the state can claim any Medicaid recovery first. Skip it and the bank's legal department will ask for proof of mailing.

The $100,000 counts only probate assets — community property passing to a spouse by agreement, joint accounts and beneficiary accounts are outside it.
