Oklahoma Advance Directive for Health Care

An Oklahoma advance directive for health care is one document that can hold a living will, the appointment of a health care proxy, and an anatomical gift. You sign it, two adults who will not inherit from you witness it, and no notary takes part. The rules sit in the Oklahoma Advance Directive Act at 63 O.S. §§ 3101.1 through 3101.16, in force since September 1, 1992 and carrying its current name since 2006.

Every rule below was read in the Oklahoma Legislature's official compilation of Title 63, current through the 2025 session, and each section is cited where it appears. Read this page as a map of the statute, then have a licensed Oklahoma attorney draft or review what you sign. It is general information about Oklahoma law rather than advice about your situation.

Two traps run through this subject, and both come from Oklahoma having more than one statute in play. The Advance Directive Act is the only route to a decision about life-sustaining treatment. The newer Oklahoma Health Care Agent Act creates a separate agent who can never make that call. Mixing the two produces a document that cannot do the job its owner expects.

What the Statute Calls an Advance Directive

63 O.S. § 3101.3(1) defines an advance directive for health care as any writing executed under 63 O.S. § 3101.4, and says it may include a living will, the appointment of a health care proxy, or both. The definition starts with the word writing, so Oklahoma has no oral living will.

The § 3101.4(C) statutory form runs four numbered parts.

Each of the three medical conditions in Part I offers the same three initialed choices: no life-sustaining treatment but keep artificially administered nutrition and hydration, no life-sustaining treatment including nutrition and hydration, or full life-sustaining treatment. The conditions carry statutory definitions. A terminal condition results in death within six months even with treatment. Persistently unconscious means an irreversible condition in which thought and awareness of self and environment are absent. An end-stage condition means severe and permanent deterioration with incompetency and complete physical dependency, where treating the irreversible condition would be medically ineffective. Two physicians make each of those findings under 63 O.S. § 3101.3.

Signing It: Two Witnesses, No Notary

63 O.S. § 3101.4(A) states the whole execution rule in one sentence. An individual of sound mind who is eighteen or older may execute an advance directive at any time, and the directive shall be signed by the declarant and witnessed by two individuals who are eighteen or older and who are not legatees, devisees, or heirs at law.

The disqualification is about inheritance, not about blood. Plenty of Oklahoma articles say your witnesses cannot be related to you by blood or marriage, and § 3101.4(A) does not say that. A relative who takes nothing under your will and nothing under Oklahoma's descent and distribution statute is outside the statutory bar.

The form then raises its own bar. General Provision (b) has you state that your witnesses must be eighteen or older and shall not be related to you and shall not inherit from you. Signing the statutory form means adopting that sentence, so the practical answer for anyone using the state's form is to find two adults who are neither relatives nor heirs. That single choice removes the argument before it starts.

Nothing in the act asks for a notary. The word does not appear in any of the sixteen sections, and no notarial alternative to the two witnesses exists.

Nutrition and Hydration Need Their Own Sentence

This is the rule that quietly defeats homemade documents. Under 63 O.S. § 3101.4(B), a directive that is not in the statutory form and is executed in Oklahoma does not authorize withholding or withdrawing artificially administered nutrition or hydration unless it does one of two things: authorizes that step in the declarant's own words, or puts it in a separate section, paragraph, or subdivision dealing only with nutrition and hydration that the declarant separately initials, separately signs, or otherwise separately marks.

Two consequences follow. A directive downloaded from a national website and signed in Oklahoma may say plenty about life support and still fail to reach a feeding tube. And Oklahoma applies the same demand to an out-of-state directive under 63 O.S. § 3101.14, which honors a directive validly executed elsewhere but refuses to read nutrition and hydration authority into it unless the document is specific or the signer was not an Oklahoma resident when it was signed.

A separate 1987 act pushes the same direction. The Hydration and Nutrition for Incompetent Patients Act at 63 O.S. § 3080.3 presumes that every incompetent patient has directed providers to supply hydration and nutrition sufficient to sustain life, and § 3080.4 lists the narrow circumstances that rebut the presumption. Silence in Oklahoma reads as yes.

When the Directive Starts Working

Two things have to happen before the document controls anything, and 63 O.S. § 3101.5(A) names both. The directive becomes operative when it is communicated to the attending physician and the declarant is no longer able to make decisions about life-sustaining treatment. Handing it to a family member does nothing until a physician has it.

Getting to that second condition takes two doctors. A qualified patient under 63 O.S. § 3101.3(10) is a patient eighteen or older who executed a directive and who the attending physician and another physician, both having examined the patient, determined to be incapable of making an informed health care decision. 63 O.S. § 3101.7 then requires that determination to go into the medical record.

63 O.S. § 3101.4(F) carries a route for religious objectors. A person who may not have an attending physician for reasons based on established religious beliefs or tenets may name someone other than the proxy, inside the directive itself, to determine lack of decisional capacity in place of the two physicians.

Where more than one valid unrevoked directive exists, 63 O.S. § 3101.5(B) treats the last one signed as the declarant's last wishes.

Your Proxy, and the Limit Built Into the Form

The health care proxy is an adult you appoint as attorney-in-fact under 63 O.S. § 3101.3(6) to make health care decisions, including life-sustaining treatment, once two physicians find you persistently unconscious, incompetent, or otherwise incapable of communicating. 63 O.S. § 3101.4(E) gives the proxy authority to make treatment decisions in consultation with the attending physician if the directive so indicates.

Part II of the form draws the line plainly. Your proxy may make whatever medical treatment decisions you could make if you were able, except that decisions on life-sustaining treatment and artificially administered nutrition and hydration can be made only as you indicated in Part I. A proxy named in a document with a blank Part I holds ordinary medical authority and no authority over the choice most families are afraid of.

Part II also treats a blank as an answer. The form states that failing to designate a proxy is a deliberate declination. 63 O.S. § 3101.12(G) softens that by preserving any decision-making authority a person holds under other law.

Whoever decides for you carries a standard, not a free hand. 63 O.S. § 3101.16 requires decisions based on your known intentions, personal views, and best interests, with your wishes controlling where the evidence of them is sufficient, and the decider's reasonable judgment about your values filling the gap where it is not.

The Second Act: a Health Care Power of Attorney That Cannot Reach Life Support

Oklahoma added the Health Care Agent Act at 63 O.S. §§ 3111.1 through 3111.13 in 2022. It creates a power of attorney for health care, and readers who find it online often assume it replaced the advance directive. It did not.

The Agent Act instrument has real strengths. Under 63 O.S. § 3111.3(C) the agent's authority begins on a determination that the principal lacks capacity and ends on a determination that capacity returned, and § 3111.3(D) puts that call with the attending physician unless the document says otherwise. A decision by the agent is effective without judicial approval under § 3111.3(F), and § 3111.3(H) validates a power in substantial compliance with the act regardless of when or where it was executed. Unless related to the principal by blood, marriage, or adoption, the agent may not be an owner, operator, or employee of the residential long-term health care institution where the principal is receiving care.

Anyone who wants both an agent for daily medical decisions and a settled answer on life support signs both documents. The notary alternative in § 3111.3(G) came in through Laws 2023, c. 154, and it applies to that document alone.

If You Sign Nothing

Oklahoma supplies a decision-maker rather than sending the family to court. 63 O.S. § 3102.4(A) applies when an adult patient is persistently unconscious, incompetent, or otherwise mentally or physically incapable of communicating, and ranks nine classes of people who are reasonably available and willing:

1. A general guardian of the person, or a limited guardian with authority over personal medical decisions.
2. A health care proxy or alternate proxy you designated.
3. An attorney-in-fact acting under the Oklahoma Health Care Agent Act, within that act's limits.
4. Your spouse.
5. Your adult children.
6. Your parents.
7. Your adult siblings.
8. Other adult relatives in order of kinship.
9. Close friends who kept regular contact sufficient to know your personal values. An affidavit stating the facts of that contact is prima facie evidence of close friendship.

Disagreement inside a class goes to a majority of that class rather than down to the next one. A provider or any class member may petition the court that would hear a guardianship, and on motion the court must order care whose denial would likely cause or hasten death while the case is pending.

Anyone acting under this ladder signs a certification first. 63 O.S. § 3102.4(B) prints the text: the person certifies no conviction or plea for caregiver abuse, verbal abuse, neglect or financial exploitation, exploitation of an elderly or disabled adult, or child abuse; no final agency or administrative-law-judge finding of abuse, verbal abuse, or exploitation; and no criminal charge as a person responsible for a vulnerable adult in a case involving death or near death. The signed statement goes into the medical record. 63 O.S. § 3102.5 makes those same findings a disqualification and shields a provider who follows an unknowingly disqualified person in good faith.

That ladder is the court-free default, and the alternative to it is a guardianship proceeding. Anyone weighing the two should read Oklahoma guardianship planning before deciding a directive can wait.

Pregnancy

63 O.S. § 3101.8(C) is a hard rule with a narrow exit. A qualified patient diagnosed as pregnant, where the attending physician knows of the diagnosis, shall be provided with life-sustaining treatment and artificially administered hydration and nutrition. The exception applies only where the patient specifically authorized, in her own words, that treatment or hydration or nutrition be withheld or withdrawn during a course of pregnancy. Where pregnancy is not known, the physician determines it where appropriate considering age and other relevant factors. General Provision (c) of the statutory form states the same rule in the declarant's voice.

Revoking, and What a New Directive Does to the Old One

Revocation is the loosest step in the act. 63 O.S. § 3101.6(A) allows revocation in whole or in part, at any time and in any manner, without regard to the declarant's mental or physical condition. It becomes effective when communicated to the attending physician or another provider by the declarant or by a witness to the revocation, and § 3101.6(B) puts the revocation in the medical record.

Signing a new directive clears the old ones. General Provision (g) of the form has the declarant agree that signing revokes any prior directives, and 63 O.S. § 3101.5(B) treats the last directive as the operative one where more than one survives.

The Health Care Agent Act runs its own revocation rules at 63 O.S. § 3111.4: a signed writing or personally informing the provider, a duty on whoever learns of it to tell the attending physician and the facility, automatic revocation of a spouse as agent by a decree of annulment, divorce, dissolution, or legal separation unless the decree or the power says otherwise, and revocation of an earlier power by a later conflicting one.

DNR Consent and POLST Sit Beside the Directive

Two medical instruments handle the emergency that a planning document cannot.

Under the Oklahoma Do-Not-Resuscitate Act at 63 O.S. § 3131.1 et seq., every person is presumed to consent to cardiopulmonary resuscitation unless one of the § 3131.4(A) exceptions applies. Those exceptions include a signed DNR consent form, notice to the attending physician entered in the record, a representative's decision based on known wishes, and an advance directive that already says treatment is not to be performed on cardiac or respiratory arrest. The consent form at § 3131.5(B) is signed by the person or by a representative, meaning an attorney-in-fact under the Health Care Agent Act, a proxy under the Advance Directive Act, or a guardian of the person. It carries two witness lines, and § 3131.5(C) applies the same witness rule the advance directive uses: eighteen or older, and not legatees, devisees, or heirs at law. § 3131.5(D) calls that form preferred rather than required. 63 O.S. § 3131.7 lets a patient revoke by oral, written, or other communication to a provider, or, outside a health care agency's care, by destroying the form and removing DNR identification and telling the attending physician.

The Physician Orders for Life-Sustaining Treatment Act at 63 O.S. §§ 3105.1 through 3105.5 covers Oklahoma's portable medical order. The Office of the Attorney General sets the standardized format under § 3105.3(A), and a POLST is executed, implemented, reviewed, and revoked according to the instructions printed on that form. A POLST, POST, MOLST, MOST, TPOPP, or similar document that does not match the Oklahoma format has a short life: one executed out of state stops being valid ten days after admission to an Oklahoma medical care facility, and a standardized Oklahoma form signed later supersedes it immediately. Under § 3105.3(B), where a capable patient's condition changes so that withholding care the POLST rejected would cause or hasten death, the attending physician has to discuss it and confirm the patient still wants the order to control.

Where the Form Lives, and the Registry Question

63 O.S. § 3102.2 tells the State Department of Health to maintain a website of advance directive forms available for download and for word processing, with the § 3101.4(C) form under the heading Statutory Advance Directive Form and any submitted alternatives under a second heading carrying a disclaimer the statute writes out word for word. The Department's advance directives page does exactly that, offering the statutory form as a 24.7 KB Word file and an 87.1 KB PDF, and stating under the second heading that it has yet to receive any alternative forms.

The registry is the part worth understanding before you count on it. 63 O.S. § 3102.1(A) directs the Department to establish and maintain an advance directives registry accessible through a Department website, and § 3102.1(C) lets the Department contract with private vendors for the services needed. The page as published on September 2, 2026 carries a heading for publicly available advance directive registry services and one link, to MyDirectives, along with a statement that the Department neither endorses nor approves any of the linked services and that the user assumes the risk of using them.

Treat distribution as your job. Give signed copies to your proxy, your alternate, your doctors, and the hospital you would most likely use. 63 O.S. § 3101.4(D) requires a physician or other provider furnished the original or a photocopy to make it part of your medical record and, where unwilling to comply with it, to tell you promptly.

Interfering With a Directive Is a Felony

63 O.S. § 3101.11 is criminal law, and Oklahoma sharpened it recently. Willfully concealing, canceling, defacing, altering, or obliterating another person's advance directive without consent is a Class D3 felony, and so is falsifying or forging a revocation. So is falsifying or forging the directive itself, or willfully concealing or withholding personal knowledge of a revocation. So is requiring or prohibiting the execution of a directive as a condition of being insured for or receiving health care, a prohibition § 3101.12(C) repeats in civil terms. So is coercing or fraudulently inducing someone to execute a directive or a revocation. Each carries imprisonment under 21 O.S. § 20P(B) through (F), a felony classification written by Laws 2025, c. 486, § 737 and effective January 1, 2026. Subsection (G) leaves every other sanction in place.

Two subsections also make failures by clinicians unprofessional conduct: willfully failing to arrange transfer of care under § 3101.9, and willfully failing to record the two-physician determination under § 3101.7.

When a Provider Will Not Comply

63 O.S. § 3101.9 sets the transfer duty. A physician or other provider unwilling to comply with the act must, as promptly as practicable, take all reasonable steps to arrange care by someone else once the declarant becomes a qualified patient. Where a relationship already exists and the refusal would in reasonable medical judgment be likely to result in death, the provider must follow the treatment decision until the transfer to a willing provider is complete.

The section carries its own limits. It does not require treatment a provider is physically or legally unable to give, or unable to give without denying the same treatment to another patient, and it does not change any obligation about a patient who cannot pay.

63 O.S. § 3101.10 protects the people acting in good faith. Absent knowledge of a revocation, carrying out a directive under the act draws no civil liability, criminal liability, or professional discipline. A provider whose actions meet reasonable medical standards is protected, and so is a proxy whose decisions are made in good faith under the act.

Directives Signed Before a Law Change, or in Another State

Old paperwork stays good. 63 O.S. § 3101.15(A) keeps a directive to a physician signed before September 1, 1992 under the former Oklahoma Natural Death Act enforceable according to its terms until revoked, and § 3101.15(B) does the same for any directive that substantially complied with the law in effect when it was signed. A directive that was valid when executed does not need redoing.

Out-of-state documents come in through 63 O.S. § 3101.14. A directive executed in another state in compliance with that state's law or Oklahoma's is valid here to the extent it does not exceed what Oklahoma law allows, subject to the nutrition and hydration proviso covered above. 63 O.S. § 3101.13 lets a physician or provider presume, absent knowledge to the contrary, that a directive complies with the act and is valid.

Where This Sits in an Oklahoma Plan

An advance directive covers medical decisions and stops there. Money and property run through a separate document under separate statutes, and Oklahoma keeps two live financial power of attorney acts, so read the Oklahoma power of attorney page before signing anything financial. For the rest of the planning set, start at Oklahoma estate planning basics.

Everything on this page ends at death. Your directive has no force after that, an anatomical gift in Part III does, and what happens next is described in the Oklahoma probate guide. The document that says who inherits is a different one again, with its own execution rules at Oklahoma will requirements.

Frequently Asked Questions

How many witnesses does an Oklahoma advance directive need?

Two. 63 O.S. § 3101.4(A) says the advance directive shall be signed by the declarant and witnessed by two individuals who are eighteen years of age or older and who are not legatees, devisees, or heirs at law. The disqualification tracks inheritance rather than family. A cousin who takes nothing under your will and nothing under Oklahoma intestacy may witness. The statutory form itself goes further and has you state that your witnesses shall not be related to you and shall not inherit from you, so pick two adults who are neither.

Does an Oklahoma advance directive have to be notarized?

No. The Oklahoma Advance Directive Act never mentions a notary, and 63 O.S. § 3101.4(A) offers no notarial substitute for the two witnesses. A different document does offer that choice. A power of attorney for health care under the Oklahoma Health Care Agent Act may be signed before a notary public or witnessed by two qualifying adults under 63 O.S. § 3111.3(G). That easier route does not reach the advance directive, and the Agent Act document it covers cannot authorize withholding life-sustaining treatment.

Who makes health care decisions in Oklahoma if I never signed a directive?

63 O.S. § 3102.4(A) sets nine classes in priority order: a guardian of the person with medical authority, a health care proxy, an attorney-in-fact under the Health Care Agent Act, your spouse, your adult children, your parents, your adult siblings, other adult relatives in order of kinship, and close friends who kept regular contact. If people inside one class disagree, a majority of that class decides. Anyone stepping in must first sign a certification about abuse and exploitation findings and hand it to the provider for your medical record.

Can my Oklahoma health care agent stop a feeding tube?

Only through the advance directive, and only if you said so yourself. 63 O.S. § 3111.3(B) bars an agent under the Health Care Agent Act from withholding or withdrawing life-sustaining treatment, nutrition, or hydration, and § 3111.2(6) writes nutrition and hydration out of the definition of a health care decision entirely. Those calls run through the Advance Directive Act instead, and 63 O.S. § 3101.4(B) says a directive outside the statutory form does not authorize withdrawing artificially administered nutrition or hydration unless you authorized it in your own words or in a separately initialed section dealing only with that subject.

What happens to my Oklahoma advance directive if I am pregnant?

63 O.S. § 3101.8(C) says a qualified patient diagnosed as pregnant, where the attending physician knows of the diagnosis, shall be provided with life-sustaining treatment and artificially administered hydration and nutrition. The one exit is your own writing: the subsection lifts the rule where the patient has specifically authorized, in her own words, that treatment or hydration or nutrition be withheld or withdrawn during a course of pregnancy. Where pregnancy is unknown, the physician determines it where appropriate considering age and other relevant factors.

Where do I get the official Oklahoma advance directive form?

The Oklahoma State Department of Health posts it. Under 63 O.S. § 3102.2 the Department maintains a website of downloadable advance directive forms, with the § 3101.4(C) statutory form under the heading Statutory Advance Directive Form. Its advance directives page carries that form as a Word document and a PDF. As of September 2, 2026 the Alternative Advance Directive Forms heading says the Department has yet to receive any alternative forms.

Can I sign an Oklahoma advance directive electronically?

The statutes now say yes, and hospital practice is the open question. The Uniform Electronic Estate Planning Documents Act, 84 O.S. §§ 911 through 927, took effect November 1, 2024, and § 912(5)(a)(7) names an advance directive as a non-testamentary estate planning document it covers. Section 917 satisfies a writing requirement with an electronic record and a signature requirement with an electronic signature, and § 920(B) satisfies an in-presence witnessing requirement where the people are in each other's electronic presence. None of that reduces the count: 63 O.S. § 3101.4(A) still asks for two qualifying witnesses. Ask an Oklahoma attorney before you rely on an electronic signature for this document.

It is not legal advice.
