Legal authority

  • 84 Okla. Stat. § 55 — Formal requisites in execution; self-proved wills (including codicils)
  • 84 Okla. Stat. § 41 — Codicil defined; how far will and codicil constitute one instrument

Estate planning documents decide what happens to your property, your children, and your medical care when you cannot make those decisions yourself. Wills, trusts, powers of attorney, and health care directives each serve different purposes and each have to meet state law requirements for signing, witnessing, and notarization. A document that looks fine on the page but was not executed correctly can be rejected in probate, which is exactly when it is too late to fix.

Not legal advice

This template is provided for informational purposes. We recommend having an attorney review any legal document before signing, especially for high-value or complex matters.

Checked against the law it cites

The statutes this template relies on are listed under Legal authority.
