Florida Will Requirements: How to Make a Valid Will

Florida Statute 732.502 sets strict execution requirements for wills. Miss one — a single witness instead of two, a missing signature, an interested witness — and a court can declare the entire document invalid. Here is exactly what Florida law requires.

The Four Requirements for a Valid Florida Will

1. The testator must be at least 18 years old and of sound mind. Sound mind means you understand what property you own, who your natural beneficiaries are, and what the will does. A diagnosis of dementia does not automatically disqualify someone — the legal standard is capacity at the moment of signing.

2. The will must be in writing. Florida does not recognize oral (nuncupative) wills under any circumstance. The document can be typed, printed, or prepared by an attorney — but it must be a physical written instrument.

3. The testator must sign the will at the end. The signature must be at the end of the document. If the testator cannot physically sign, they may direct another person to sign on their behalf, in their presence.

4. Two witnesses must sign in the testator's presence and in each other's presence. Both witnesses must watch the testator sign (or acknowledge a prior signature), and then sign the will themselves while all three people are together. This simultaneous-presence requirement is strict — witnesses who sign at different times or in different rooms can invalidate the will.

Who Can Witness a Will in Florida?

Any competent adult can serve as a witness. Florida does not require witnesses to be disinterested — a beneficiary under the will can legally witness it. However, using a beneficiary as a witness creates a rebuttable presumption of undue influence, which invites will contests. Best practice: use two witnesses who receive nothing under the will.

A notary public can serve as one of the two witnesses but cannot replace both.

The Self-Proving Affidavit

A self-proving affidavit under Florida Statute 732.503 is technically optional — but practically essential. Without one, the probate court must locate your witnesses after your death and obtain their testimony to validate the will. If a witness has moved, died, or cannot be found, probate stalls.

The self-proving affidavit is a sworn statement signed by the testator, both witnesses, and a notary public at the time the will is executed. It confirms that execution formalities were followed. With this affidavit attached, the will is admitted to probate without further proof.

The signing ceremony sequence:

1. The testator declares the document as their will
2. The testator signs
3. Both witnesses sign
4. All three sign the self-proving affidavit
5. The notary acknowledges and seals

All of this happens in the same room, at the same time.

Naming a Guardian for Minor Children

A will is the only legal document that allows you to nominate a guardian for your minor children. Under Florida Statute 744.3046, the court gives preference to the guardian named in the last will — though the nomination is not absolutely binding if the court finds the named guardian unfit.

If you die without naming a guardian, the court appoints one based on statutory preference — typically the surviving parent, then nearest relatives. Without clear direction, family disputes over guardianship can drag out for months.

What Makes a Florida Will Invalid

• Holographic wills (handwritten, unwitnessed) are not valid in Florida, even if valid in the state where they were written
• Only one witness signed — Florida requires two, no exceptions
• Witnesses signed at different times or were not both present when the testator signed
• The signature is not at the end of the document
• The testator was under undue influence or lacked testamentary capacity
• A later will or codicil revokes it — Florida follows the "last valid will" rule

Florida Will vs. Other Estate Planning Tools

A will controls only probate assets — property titled in your name alone without a beneficiary designation. It does not control joint accounts, life insurance proceeds, retirement accounts with named beneficiaries, or property held in a trust.

For many Florida families, the will is one piece of a broader plan that includes a durable power of attorney, healthcare surrogate designation, and probate avoidance tools like Lady Bird deeds or pay-on-death designations.

The Florida Basic Estate Planning Kit covers all of these documents — including the signing ceremony protocol and a guardianship nomination worksheet.
