Oklahoma executor and estate paperwork checklist

This is an organizer, not legal advice. An estate attorney or the county probate/surrogate office answers questions about your situation.

The first 30 days

Work down the list; nothing you tick is saved or sent. The steps are general, the dates come from the official pages.

1. Get several certified copies of the death certificateThe funeral home can usually order them, or the vital records office can. Each bank, insurer and pension plan may ask for its own.
2. Confirm the death was reported to Social SecurityUsually the funeral home does this. If it didn't, phone 1-800-772-1213 (TTY 1-800-325-0778); a widow or widower, or certain children, may qualify for $255.
3. Find the original willLook for the signed original and any codicils (later changes). Keep the original safe and unaltered; make copies for yourself.
4. See whether a self-proving affidavit is attachedIt's a sworn page signed by the witnesses, usually at the end of the will; the rule for this state is below.
5. Secure the home, car and mailLock up, keep the insurance in force, photograph valuables and forward the mail to yourself.
6. Pause before paying creditors or dividing keepsakesWho may act, and in what order bills get paid, depends on the route. Ask before you spend or distribute anything.
7. Stop using the person's power of attorneyA power of attorney ends at the principal's death, so an agent under it can't act for the estate.
8. Write down every asset and debtFor each, record whose name it's in and whether a beneficiary or co-owner is listed; those usually go straight to that person.
9. Check the total against $50,000The official page's small estate figure. Leave out anything the page says isn't counted.
10. Keep an account of every transactionWrite down each payment and each deposit with the date and a receipt; heirs and the court may ask to see it.
11. Get the estate its own tax number and bank accountThe IRS asks for an EIN before the estate's Form 1041, which applies once the estate has more than $600 of gross income in a year.
