Free Hawaii Codicil to a Will

In Hawaii, a codicil is signed before 2 witnesses, like a will, and the self-proving affidavit signed with it lets the court admit it without witness testimony.

A will is changed by a codicil, a separate signed instrument that adds, revokes or replaces provisions of the will and republishes the rest, or by a new will that revokes the old one. Hawaii's probate code defines a will to include a codicil, so a codicil is signed and witnessed the way a will is and can be made self-proved with the same affidavit. The codicil prepared here names the will by its date, states each change as a numbered amendment, and prints the execution block Hawaii requires for a will.

Hawaii requires 2 witnesses present when the testator signs a will, and a codicil is signed the same way: Hawaii's probate code defines a will to include a codicil, so a codicil is signed and witnessed the way a will is and can be made self-proved with the same affidavit.

Hawaii does not require a notary for a will to be valid, and a codicil follows the will's execution rule. The notary's role is the self-proving affidavit: Hawaii extends the self-proving affidavit to a codicil, so the testator and witnesses sign it with the codicil and the codicil enters probate without the witnesses testifying.

A will is changed by its maker. In Hawaii the testator must be at least 18 years old, and a codicil is the testator's own signed instrument: Hawaii's probate code defines a will to include a codicil, so a codicil is signed and witnessed the way a will is and can be made self-proved with the same affidavit. A power of attorney names an agent to act for you in the matters it lists while you are living, and an executor administers the estate under the will as admitted; neither document is the testator's signature on a codicil or a new will.

Hawaii recognizes a handwritten will without witnesses, and that rule is the will's. The codicil prepared here is typed and signed before 2 witnesses, as the Hawaii will is, so it does not depend on the handwriting rule.

A Codicil to a Will in Hawaii

A will is amended by a codicil, a signed instrument that names the will by its date, states each change, and republishes the rest. Hawaii's probate code defines a will to include a codicil, so a codicil is signed and witnessed the way a will is and can be made self-proved with the same affidavit.

In Hawaii a will is signed before 2 witnesses, and notarization is not required for validity; the codicil prints the same attestation for its witnesses, naming the instrument as a codicil to the will.

Hawaii extends the self-proving affidavit to a codicil: the testator and the witnesses sign it before a notary public, and the codicil enters probate without the witnesses appearing in court. The affidavit prints after the attestation, with the instrument named as a codicil.

The codicil names the will by its date and any earlier codicils, states each change as a numbered amendment (a provision added, revoked or replaced, in the words the will uses for it), ratifies and republishes the will as amended, and names the state whose law governs it. The signing page carries the state's witness rule, the self-proving status and the record's notes.

A new will is the other instrument of change: the Hawaii will prepared here revokes all earlier wills and codicils by its own declaration, so a change that reaches most of a will's provisions is made that way, and a change to a few is made by codicil.
