A self-proving will is a standard will with a notarized affidavit, signed by your witnesses, confirming the will was executed properly and that you had testamentary capacity at signing. According to Cornell Law School's Legal Information Institute, this affidavit lets a will move through probate without your witnesses appearing in court to testify.
Self-Proving Will Versus a Notarized Will
These are often confused, but they serve different purposes. Notarizing a will simply confirms the testator's identity and signature. A self-proving affidavit is a separate document, signed by the testator and witnesses and notarized, that specifically attests the will was executed according to legal formalities. Notarizing your signature does not automatically make your will self-proving; you need the separate affidavit for that.
How to Make a Self-Proving Will
- Draft the will using an attorney or a platform built around your state's requirements.
- Execute the will by signing in front of two or more witnesses who are not beneficiaries or heirs named in the document.
- Prepare the self-proving affidavit, a sworn statement by the testator and witnesses confirming the will was signed voluntarily, in their presence, and that the testator appeared to be of sound mind and of legal age.
- Notarize the affidavit so it carries evidentiary weight in probate court.
- Store the will and affidavit together somewhere your executor and trusted family members can find them.
Why a Self-Proving Affidavit Matters
Without one, your witnesses may need to appear in Surrogate's or probate court, years after signing, to confirm they watched you sign the will and believed you understood what you were doing. Witnesses move, lose touch, become ill, or die in the years between signing a will and a person's actual death. A self-proving affidavit removes that dependency entirely, and the notarization step adds another layer of protection: the National Notary Association notes that notaries face real pressure to cut corners in roughly 30 percent of cases, which is part of why a properly notarized affidavit, rather than an informal signature, carries weight in court.
Disadvantages to Weigh
- Extra formalities: creating the affidavit adds a step and requires all signers to be notarized together, which can be more coordination than a basic will.
- Witness availability still matters if challenged: if the will is contested on other grounds, like undue influence or fraud, the affidavit does not eliminate the value of being able to locate your original witnesses.
- Public record: like any will, a self-proving will and its contents become part of the public probate record once filed, so privacy-sensitive families may want to also consider a trust for certain assets.
- Jurisdictional variation: not every state recognizes self-proving wills. Maryland, Ohio, Vermont, and the District of Columbia do not, so confirm your state's rule before assuming this option applies to you.
- Limited flexibility: changing a self-proving will after execution generally requires the same formalities as creating the original, including a new or updated affidavit.
A Worked Example
Say two siblings signed as witnesses to their aunt's will fifteen years before she died. By the time she passed, one witness had moved overseas and the other had passed away. Without a self-proving affidavit, her executor would have faced real delay trying to establish that the will was properly witnessed at all. Because she had signed a self-proving affidavit at the same time as her will, her executor simply submitted it to the court, and probate proceeded without ever needing to track down a witness who could no longer be found.
Do You Actually Need One?
If your state recognizes self-proving wills, there is rarely a good reason to skip the affidavit. The extra step at signing is minor compared to the time and cost your executor could otherwise face locating witnesses years later. The main exception is if you live in one of the small number of states that do not recognize the concept at all, in which case a standard, properly witnessed will is what you need instead.
How FastWill Handles This
FastWill's online will builder tells you whether a self-proving affidavit is available in your state and walks you through preparing it alongside your will, including remote notarization if you would rather not schedule an in-person appointment. For the specific list of items your will should cover once it is properly executed, see things you should always put in your will.
A Quick Cost-Benefit Check
Weigh the small extra effort of notarizing one additional document against the realistic odds that a witness becomes unreachable years or decades later. For most people, that trade clearly favors adding the affidavit.
Frequently Asked Questions
Is a self-proving will more legally binding than a regular will?
No, it is not more valid, just easier to prove in probate court. A regular, properly witnessed will is just as legally binding; the self-proving affidavit simply removes the need for witness testimony later.
Do all states allow self-proving wills?
No. Most states do, but Maryland, Ohio, Vermont, and the District of Columbia do not recognize the concept. Confirm your state's rule before assuming this option applies to you.
Can I add a self-proving affidavit to a will I already signed?
In many states, yes, through a separate signing and notarization with your original witnesses, though the exact process varies. It is simpler to build it in from the start.
Does notarizing my signature make my will self-proving?
No. Notarization confirms your identity and signature. A self-proving will requires the separate affidavit signed by you and your witnesses.
What happens if my witnesses cannot be found after I die?
Without a self-proving affidavit, courts may require additional steps to establish the will's validity, which can slow probate. With the affidavit in place, this is generally not an issue.
