Wills, Trusts, and Notarization: What Kansas Law Actually Requires

A lot of people believe a will has to be notarized to be legally valid in Kansas. It doesn't. What a will needs, generally, is the testator's signature and the signatures of witnesses — not a notary. And yet almost every will I see does get a notary involved anyway, for a very good reason that has nothing to do with the will itself: the self-proving affidavit.

What actually makes a will valid

Under Kansas law, a will generally needs to be signed by the person making it and witnessed by others who watched them sign (or acknowledge their signature) and then sign themselves. That's the baseline. No notary required for the will to be legally effective. This trips people up because it runs against the instinct that anything this important must need a notary — plenty of important documents don't, as I mentioned in a separate article on what actually needs notarizing.

The self-proving affidavit: the part that does get notarized

Here's the practical issue: without more, if your will is ever challenged or simply needs to be admitted to probate, the court may need your witnesses to testify — in person, potentially years later — that they actually watched you sign. Tracking down witnesses after someone has passed away, possibly after they've moved states or passed away themselves, is exactly the kind of delay a grieving family doesn't need.

A self-proving affidavit solves this. It's a separate sworn statement, signed by the testator and witnesses in front of a notary at the same time the will is signed, stating that everything was done properly. Because it's notarized, it generally lets the will be accepted by the probate court without needing to track down and question the witnesses later. This is the document — not the will itself — that a notary is actually notarizing in most will-signing appointments.

Trusts: notarized more often, for a different reason

Trust documents don't have a uniform notarization requirement the way wills have witness requirements, but certain related documents usually do get notarized:

• Certifications of trust — a shorter document proving a trust exists and who the trustee is, frequently notarized because banks and title companies want that certainty before they'll deal with a trustee.
• Trust amendments — often notarized for the same evidentiary reasons a self-proving affidavit exists: it removes any later question about who actually signed and when.
• Real property transfers into a trust — if a trust is taking title to real estate, the deed itself needs notarization the same way any real estate deed does.

Notarizing a will doesn't make it more valid. Notarizing the self-proving affidavit that goes with it can make your family's probate process considerably less painful. That distinction is worth understanding before you assume either document is optional.

What we can and can't help with

We can notarize your self-proving affidavit, trust certification, or related signatures. We can't draft your will or trust, tell you whether your estate plan actually accomplishes what you want, or explain the legal effect of any clause in it — that's squarely an attorney's job, not a notary's, and it's a meaningful enough distinction that Marlene wrote a full article on it: what's the difference between a notary and an attorney. If you haven't had your will or trust drafted or reviewed by a Kansas estate planning attorney yet, that's the step to take before scheduling a signing, not after.

Revocable vs. irrevocable trusts — does it change the notarization?

Not fundamentally. Whether a trust is revocable (the person who created it can change or cancel it) or irrevocable (generally locked in once signed) doesn't change how the notarization itself works — the notary is still confirming identity and willing signature, not evaluating the trust's terms or structure. What does change is how carefully I'd expect the underlying document to have been drafted, since an irrevocable trust is a much harder decision to walk back later. That's exactly the kind of thing worth getting right with an attorney before the signing, not something to sort out at the notary table.

Codicils and amendments

A codicil is a formal amendment to an existing will, rather than rewriting the whole document. Like the original will, a codicil generally needs witnesses to be valid, and like the original, it's often paired with its own self-proving affidavit for the same reason — to avoid needing witnesses to testify later. If you're amending an older will, treat the codicil signing with the same care as the original: right witnesses, right notarization, stored somewhere it'll actually be found alongside the original document.

Common questions

Does Kansas require a specific number of witnesses for a will? Generally two, but exact requirements and who's eligible to serve as a witness are questions for the attorney drafting your will, since details matter and I'd rather not oversimplify them here.

Can a beneficiary of the will also serve as a witness? This can create complications depending on the circumstances — another good question for your estate planning attorney before the signing, not after.

Do you notarize wills that were drafted without an attorney? Yes, we'll notarize any properly prepared document brought to us. Whether a self-drafted will accomplishes what you intend is a separate question we can't answer, and it's exactly the kind of gap that a quick attorney review tends to catch before it becomes a problem for your family.

A modern wrinkle: digital assets

Estate planning has had to catch up to the fact that a meaningful part of many people's lives — photos, financial accounts, cryptocurrency, email — now exists only digitally, with no physical paperwork trail leading a family member to it. Some wills and trusts now include a digital asset provision, sometimes paired with a separate, securely stored list of accounts and access instructions (never included directly in the will itself, since wills often become public record during probate — not where you want your passwords listed). Notarizing a will with this kind of provision doesn't work any differently than any other will, but it's worth mentioning to your estate planning attorney if your existing documents predate this becoming common practice, since older wills sometimes don't address it at all.

If it's been a while since you looked at your documents

Estate plans drafted a decade or more ago sometimes reflect an older family situation entirely — a beneficiary who's since passed away, a guardian who's no longer the right choice, or simply a life that's changed shape since the original signing. Notarization doesn't need to happen again unless the document itself changes, but it's a reasonable prompt to ask your attorney whether the underlying plan still reflects your actual wishes, not just whether the paperwork is technically valid.

Whatever stage you're at — drafting a first will, updating an old one, or just making sure a trust certification is ready for a bank — the notarization step is usually the smallest part of the process and the easiest to get right, as long as it happens after the harder work of drafting is already settled, with the right attorney, well before anyone's counting on the document actually holding up.
