Connecticut Will Requirements: What Makes a Will Legally Valid

A will in Connecticut must meet specific execution requirements or it is void from the start — regardless of how clearly it states your wishes. The state does not recognize holographic (handwritten, unwitnessed) wills, and an improperly witnessed will cannot be admitted to probate.

The Basic Validity Requirements

Under Connecticut General Statutes, a valid will requires:

1. The testator must be at least 18 years old
2. The testator must have testamentary capacity — understanding the nature and extent of their property, who their natural heirs are, and that they are making a will
3. The will must be in writing — oral (nuncupative) wills are not recognized
4. The testator must sign the will (or direct someone to sign on their behalf in their presence)
5. At least two adult witnesses must sign in the testator's presence

There is no requirement that the will be notarized for basic validity. However, without a self-proving affidavit, the witnesses must physically appear in Probate Court after the testator's death to confirm the signature — which can be impossible if witnesses have moved, become incapacitated, or died.

Who Can Witness a Connecticut Will

Connecticut imposes few restrictions on witnesses:

• Must be adults (18 or older)
• Must be present when the testator signs (or acknowledges their signature)
• Must sign the will themselves in the testator's presence

Interested witnesses: Connecticut does not void a will because a beneficiary served as a witness. However, naming a beneficiary as a witness creates grounds for a will contest — opposing parties can argue undue influence. Best practice: use witnesses who receive nothing under the will.

Notary as witness: A notary public can simultaneously serve as a witness and perform the notarization for the self-proving affidavit. This means you technically need only one additional witness beyond the notary, rather than two separate witnesses plus a notary.

The Self-Proving Affidavit: Form PC-210

A self-proving affidavit (Form PC-210) eliminates the need for witnesses to appear in Probate Court after your death. It is a sworn statement, signed by both the testator and witnesses before a notary public, confirming the will was properly executed.

The affidavit can be executed at the same time as the will (recommended) or added later while all parties are still available and competent.

Without a self-proving affidavit, the Probate Court must independently verify the will's validity — either through witness testimony or, if witnesses are unavailable, through other evidence of the testator's signature. This adds weeks to probate and creates risk if witnesses cannot be located.

Common Mistakes That Void Connecticut Wills

Only one witness signed. Connecticut requires two. A will with a single witness — even if notarized — is invalid and cannot be probated. The estate defaults to intestacy.

Witnesses were not present simultaneously. Both witnesses must observe the testator sign (or hear the testator acknowledge their signature). Having one witness sign in the morning and another in the afternoon invalidates the execution.

The testator signed after witnesses left. The signing must occur in the witnesses' presence. If the testator forgot to sign during the ceremony and added their signature later alone, the will is defective.

Using a form from another state. While the content may be fine, execution requirements vary. A will validly executed under another state's law (e.g., a state allowing holographic wills) may still be admitted in Connecticut under the "foreign will" doctrine — but this creates additional court proceedings and uncertainty.

Alterations after execution. Crossing out provisions, adding handwritten notes, or attaching pages after the will was witnessed can partially or entirely void the document. Changes require a formal codicil (with its own two-witness execution) or a new will entirely.

Revoking a Connecticut Will

A will is revoked by:

• Executing a new will that expressly revokes prior wills
• Physically destroying the will with intent to revoke (burning, tearing, obliterating)
• A subsequent marriage (partially revokes provisions that exclude the new spouse, unless the will was made in contemplation of that marriage)
• Divorce (automatically revokes all provisions benefiting the former spouse)

Simply writing "revoked" on the will without witnesses is risky — it may work if clear intent can be demonstrated, but it creates litigation potential.

Practical Execution Checklist

For a clean, contest-resistant will signing in Connecticut:

1. Gather: testator, two adult non-beneficiary witnesses, notary public
2. Testator signs or initials each page and signs the final signature line
3. Both witnesses sign in the testator's presence
4. All three (testator + witnesses) sign the self-proving affidavit before the notary
5. Notary completes the acknowledgment block and applies their seal
6. Store the original in a fireproof location — not a bank safe deposit box (boxes are sealed at death)

The Connecticut Estate Planning Kit includes a complete signing ceremony script, a self-proving affidavit template aligned with Form PC-210, and a document storage guide explaining why a safe deposit box is the worst place to keep your original will.
