EDUCATIONAL PILLAR · SELF-PROVING AFFIDAVIT
Self-proving affidavit — what it is, and why you want one
A self-proving affidavit is a notarized statement attached to the will, in which the testator and both witnesses swear under penalty of perjury that the formal execution elements were met. It lets probate proceed without dragging witnesses into court to testify years later.
What it does
Without a self-proving affidavit, the probate court ordinarily requires at least one of the attesting witnesses to testify (in person or by deposition) that the will was properly executed. Witnesses move, die, lose memory, or simply can't be located decades later — a real, frequent obstacle to probate.
The self-proving affidavit is taken under oath at the time of execution and is treated as a substitute for live witness testimony. UPC §2-504 provides the model statutory form, which most UPC-adopting states track.
The UPC §2-504 model form (paraphrased)
The model form, executed before a notary, contains acknowledgments from:
- The testator, swearing that the document is the testator's will, that the testator willingly signed it (or willingly directed another to sign), and that the testator was 18 or older, of sound mind, and under no constraint or undue influence.
- The two witnesses, each swearing they signed in the testator's presence and in the presence of each other after the testator declared the will to be their will, and that to the best of their knowledge the testator was 18 or older, of sound mind, and under no constraint or undue influence.
- The notary, certifying that the testator and witnesses appeared and acknowledged.
State variants
Many states have adopted §2-504 verbatim; some have prescribed slightly different language. The decoder and per-state pages identify the form variant for each state, with a copy-to-clipboard utility (planned for v1.1).
Notarization is on the affidavit, not the will
Notarization is not required to validate the will itself in most states. Notarization is required on the self-proving affidavit because the affidavit is sworn under oath. The will + affidavit + two witnesses is the standard execution package.
When the will lacks an affidavit
The will may still be valid — execution requirements (witnesses + signature) are separate from the self-proving affidavit. The estate's executor will need to track down at least one attesting witness for probate proof. Run the decoder with self-proving = no to see how the verdict shifts.
Frequently asked questions
Is a self-proving affidavit required for a will to be valid?
No. The affidavit is separate from the will itself. A valid will (two witnesses + testator signature) is valid with or without an affidavit. The affidavit simply lets the will skip live witness testimony at probate.
What does the affidavit need to say?
The Uniform Probate Code §2-504 model form contains sworn statements from the testator (the document is the testator's will, signed willingly, of sound mind, etc.) and from each witness (signed in the testator's presence and in each other's presence, after the testator declared the document to be the will). Notarized.
Does every state use the UPC §2-504 form?
Most UPC-adopting states use a near-verbatim version. Some states have prescribed slightly different language — Texas (§251.104), Florida (§732.503), California (§8220) have their own form text. The state pages identify the variant in use.
Can I add a self-proving affidavit after the fact?
Yes — the affidavit can be executed at any time after the will is signed, as long as both witnesses are still available to swear to the execution. Older wills without an affidavit can still be probated, but require live witness testimony if witnesses are reachable, or an affidavit of lost witness if not.
What's the difference between an attested will and a self-proved will?
An attested will is one with two witness signatures (the baseline execution). A self-proved will has the additional notarized affidavit attached, which substitutes for live witness testimony. Self-proving is procedurally easier at probate; the underlying validity is identical.
