How to fill out Oklahoma 798

One page for the estate nobody opened. It is used where no executor or administrator has been appointed to administer the estate in the name of the deceased, the applicant is related to the decedent, and a death certificate is available. What is sworn is narrow and precise: that the deceased left no estate necessitating administration, that no letters of administration or letters testamentary have been issued to any person, that the vehicle was not bequeathed to anyone by will, and that no person living would have prior right.

Written against 798 (Rev 01/2023), issued under 47 O.S. 1105 and 1107. The sentence about prior right is not a formality. Oklahoma is asking one relative to swear that no other living person has a better claim to the vehicle, and getting that wrong in a family with more than one child is how a car becomes a dispute. Where there is any doubt at all, the small estate route with the will attached is the safer document.

Two documents, and they are not the same thing. Take the blank 798 from the oklahoma.gov copy so you get the revision that is current today.

Every line, in the order you meet it

1. 1
   Somebody else fills this in

   STATE OF OKLAHOMA, COUNTY OF

   The county where the affidavit is sworn.

   Watch out: It should be the same county as the notary block at the foot, because they describe one event.

2. 2
   Somebody else fills this in

   The affiant's name, in the opening sentence

   Whoever is swearing, printed into the rule after being first duly sworn.

   Watch out: This has to be a relative. The form's own note says the applicant must be related to the decedent, with no exceptions offered.

3. 3
   Somebody else fills this in

   The registered owner, the make, the body style and the VIN

   The deceased and the vehicle, across two rules with the labels printed underneath.

   Watch out: The labels sit below the lines rather than beside them, which is how body style and identification number end up transposed. Read downwards before writing.

4. 4
   Somebody else fills this in

   died on the __ day of __, __

   The date of death, in three boxes.

   Watch out: It has to match the death certificate exactly. That document is going in with the affidavit and a clerk will read both.

5. 5
   Somebody else fills this in

   that the undersigned is the ___ of the deceased

   The relationship - daughter, son, widow, brother.

   Watch out: Plain words. This is the field a licensed operator reads first, because it decides whether the affidavit is available at all.

6. 6
   Somebody else fills this in

   AFFIANT, ADDRESS, CITY, STATE, ZIP

   The three closing rules, then the notary block.

   Watch out: Take the death certificate and photographic identification to the notary. The affidavit alone is not enough to move anything.

What gets this one rejected

• •An affiant who is not related to the decedent. The form's own note requires the applicant to be related, and a friend or a creditor is outside it.
• •An estate that has been opened. If letters of administration or letters testamentary have issued to anybody, this affidavit is not available and the court documents are used instead.
• •A vehicle that was left to somebody by will. The affirmation includes that the vehicle has not been by will bequeathed to anyone, which sends the case to the small estate route or to probate.
• •Filed without a death certificate. The note at the head of the form makes it required supporting documentation.
• •Signed where somebody living has a better claim. The affiant swears that no person living would have prior right, which is a statement about the whole family and not just about the affiant.
• •An unsworn signature. Like almost every Oklahoma title affidavit, it needs the notary block completed.

Rules that decide whether it is accepted

• •It is the smallest estate route Oklahoma publishes. No probate, no will, no letters - just a relationship, a death certificate and a sworn statement that nobody else is ahead of you.
• •The rest of the paperwork is picked up at the counter. Service Oklahoma's instruction is that the holder of this affidavit may obtain and complete the appropriate title transfer documentation at Service Oklahoma or a licensed operator, rather than assembling it in advance.

Every line here was read off 798 (Rev 01/2023) itself — the PDF is here — and off the Service Oklahoma, Motor Vehicle Services pages. This is plain-language help with a form, not legal advice, and where our wording and the agency's differ, theirs governs.
