End-of-Life Planning: Which Documents Need a Notary, and Which Don’t

End-of-life planning covers a wide mix of documents, and they don’t all follow the same rules. Some need a notary. Some need witnesses instead, or in addition. A few need neither. Sorting this out ahead of time — rather than during a medical crisis — is one of the more valuable things a family can do for itself.

Documents that typically need notarization

• Durable power of attorney (financial), so someone can manage finances if capacity is later lost
• Self-proving affidavits that accompany a will — the will itself may not require notarization in Kansas, but the affidavit that makes probate smoother generally does; I cover this distinction in a separate article
• Trust documents and trust amendments, in most cases
• Beneficiary designation changes for certain accounts, depending on the institution’s specific requirements

Documents that usually rely on witnesses instead (or in addition)

• Advance health care directives / living wills — Kansas law generally requires witnesses rather than notarization, though notarization is sometimes used alongside witnesses for extra certainty; I go into this specific document in a dedicated article
• Medical power of attorney, depending on the exact form used — some versions call for witnesses, notarization, or both

Why the mix matters

Using the wrong execution method — notarizing something that needed witnesses, or vice versa — is one of the more common reasons end-of-life documents get challenged or rejected exactly when a family needs them to work. This is a case where confirming the correct requirement for your specific form, ideally with an estate planning attorney, matters more than assuming one method covers everything.

The goal of end-of-life paperwork is that it works exactly when it’s needed, without a fight over technicalities. Getting the execution method right the first time is how that happens.

A practical suggestion

If you’re working through several of these documents at once, ask your attorney to flag which ones need a notary specifically, and bundle those into a single appointment. It’s a natural moment to handle everything at once rather than scheduling separate visits as each document is finalized.
