PA Next of Kin Laws for Medical Decisions: Hierarchy and Limits

In Pennsylvania, next-of-kin laws for medical decisions follow a fixed order of priority. If you cannot make or communicate your own health care decisions, the first authority is any advance directive you signed while competent. If none exists, a court-appointed guardian with health care authority decides. If neither is in place, Pennsylvania’s “health care representative” statute takes over and hands the decision to your closest available family member in this order: spouse, adult child, parent, adult sibling, adult grandchild, and finally an adult who knows your values. This framework is set out in Title 20, Chapter 54 of the Pennsylvania Consolidated Statutes, enacted through Act 169 of 2006.

The Statutory Order of Next of Kin

Under 20 Pa.C.S. § 5461, when someone becomes incapable of making medical decisions and has no advance directive or guardian in place, a “health care representative” steps in from the following descending list:¹

The spouse, unless a divorce action is pending. Any adult children of the patient who are not children of that spouse share this top tier with the spouse.
An adult child.
A parent.
An adult brother or sister.
An adult grandchild.
An adult who has knowledge of the patient’s preferences and values, including moral and religious beliefs.

One person can jump the line. If the patient, while of sound mind, previously designated someone to serve as representative — through a signed writing or by telling the attending physician — that designee ranks above everyone in the family hierarchy.² A patient can also use a signed writing or health care power of attorney to disqualify a specific person from ever serving.¹

When the Next-of-Kin List Actually Applies

The hierarchy is a default rule, not a first resort. It kicks in only when all four of these conditions are met:³

The attending physician has determined the patient is incompetent to make health care decisions.
The patient is at least 18, or is a high school graduate, married, or emancipated.
There is no valid health care power of attorney in effect.
No court-appointed guardian has authority over the patient’s health care.

If a health care agent was named in a durable health care power of attorney, that person decides and the family list is never reached. If a court has appointed a guardian of the person, the guardian decides. Only when both of those are absent does a family member step forward as the health care representative.

How a Family Member Proves Their Authority

A health care representative does not need court approval to act. But a physician or hospital can ask the family member claiming authority to sign a written declaration, made under penalty of perjury, that identifies who they are, states their relationship to the patient, and confirms that no one higher on the priority list is available or willing to serve.⁴ A false statement in that declaration is a crime under Pennsylvania’s unsworn falsification statute (18 Pa.C.S. § 4904).

The representative also carries a duty to notify other family members within the statutory priority classes that they have assumed decision-making authority, to the extent those relatives can be readily contacted.

When Family Members in the Same Tier Disagree

Because multiple people can occupy the same priority level — three adult children, for example, or four siblings — disputes are common. Pennsylvania resolves them by majority rule. When the attending physician is informed of a disagreement, the physician may rely on the decision of a majority of the class members who have communicated their views.⁵

If the class splits evenly, no decision is deemed made. A relative from a lower priority class cannot step in to break the tie. The deadlock must be resolved — often through negotiation, sometimes through court intervention — before the representative’s authority can be exercised. The statute does allow one thing to continue during a stalemate: treatment consistent with accepted medical standards may still be administered.¹

Any member of the priority classes can also petition the court to disqualify another person from serving as representative for cause.

What Next of Kin Cannot Do

A family member serving as health care representative has meaningfully less authority than an agent named in a health care power of attorney. The most important limit involves life-sustaining treatment. A representative cannot unilaterally withhold or withdraw life-sustaining treatment unless the patient is in an end-stage medical condition or is permanently unconscious.⁶ An end-stage medical condition, by statute, is an incurable and irreversible condition in an advanced state that will result in death despite continued treatment.⁷

If a representative wants to withdraw life-sustaining treatment for a patient who does not meet those two criteria, they must go to court and prove by clear and convincing evidence that death is in the patient’s best interest. A health care agent named in an advance directive faces no such requirement.

Two other limits apply. A representative cannot serve if they are the patient’s attending physician, another health care provider treating the patient, or an owner, operator, or employee of the facility where the patient is receiving care — unless they are related to the patient by blood, marriage, or adoption.¹

Unmarried Partners Are Not on the List

Pennsylvania’s statutory hierarchy skips from spouse directly to adult child, then to parent, then to sibling. A long-term unmarried partner, no matter how many years the relationship has lasted, has no automatic standing to make medical decisions.⁸ Without a health care power of attorney naming them, a partner will usually watch a parent, adult child, or sibling of the patient step into the role instead.

The catch-all at the bottom of the list — “an adult who has knowledge of the principal’s preferences and values” — could theoretically include a partner, but it is the lowest priority. Any blood relative available and willing to serve outranks them. The reliable fix is a signed durable health care power of attorney naming the partner as agent.

How an Advance Directive Overrides the Default

Because the next-of-kin list only applies when no advance directive exists, understanding what an advance directive does helps clarify how the whole system fits together.

A durable health care power of attorney names a specific “health care agent” to make medical decisions whenever the principal cannot. The agent’s authority is broad: consenting to or refusing procedures, managing tube feeding and hydration, admitting or discharging from facilities, and requesting a do-not-resuscitate order.⁹ The agent’s decisions are effective without court approval.¹⁰ A living will, by contrast, does not name a decision-maker; it provides written instructions about end-of-life treatment that take effect only when the patient lacks capacity and is either permanently unconscious or has an end-stage medical condition.⁷

To be valid, either document must be dated, signed by the principal or at their direction, and witnessed by two people who are at least 18. The principal must be of sound mind and either 18, a high school graduate, married, or emancipated.¹¹ Notarization is optional for health care directives. A health care provider or their employee cannot sign on behalf of the principal.

A named agent gets the full range of decision-making power that a family representative does not, including the ability to withhold or withdraw life-sustaining treatment without meeting the end-stage or permanent-unconsciousness threshold. Even after appointing an agent, a competent patient can override the agent by personally informing the attending physician. And on the specific question of withholding or withdrawing life-sustaining treatment, even a patient who lacks capacity can countermand that decision.¹² When multiple advance directives exist and they conflict, the most recent one controls.¹⁰

When a Court-Appointed Guardian Displaces the Family List

If a court has appointed a guardian of the person with authority over health care, that guardian decides, and the next-of-kin list is bypassed. Guardianship petitions are filed in the Court of Common Pleas, Orphans Court Division, and require clear and convincing evidence of incapacity, along with testimony from a qualified professional about the person’s condition.¹³ Guardianship is treated as a last resort, and courts must consider whether family, friends, and existing advance directives already meet the person’s needs.

When both a guardian and a previously named health care agent exist, the agent continues to act but is accountable to the guardian. The guardian can revoke or amend the agent’s appointment, but cannot rewrite the instructions in an advance directive without judicial authorization.¹⁴

In emergencies, a court may appoint an emergency guardian based on clear and convincing evidence of incapacity and threatened irreparable harm. Emergency guardianship of the person is initially limited to 72 hours, extendable to 20 days, after which full proceedings must begin.¹³

Situations That Change the Answer

Pregnancy

If the patient is pregnant, the ordinary rules bend. Under 20 Pa.C.S. § 5429, life-sustaining treatment, nutrition, and hydration must be provided to a pregnant woman who is incompetent and has an end-stage medical condition or is permanently unconscious, regardless of what her living will or health care agent directs. Three exceptions apply: an attending physician and an obstetrician may certify in the medical record that continued treatment will not permit the live birth of the child, will be physically harmful to the woman, or will cause pain that cannot be alleviated by medication. Physicians are not required to perform pregnancy tests unless they have reason to believe the woman may be pregnant. The Commonwealth pays the usual, customary, and reasonable expenses of the required treatment, treated as a grant with no lien on the woman’s property or estate.¹⁵

Minors

For patients under 18, the default decision-makers are parents and legal guardians. Under 11 P.S. § 2513, a parent, legal guardian, or legal custodian may consent to medical, surgical, dental, and mental health treatment for a minor, and may delegate that authority to another adult through a written Medical Consent Authorization signed before two witnesses.¹⁶ Minors gain limited authority to consent on their own in some situations: a minor who is 18, a high school graduate, married, or has been pregnant may consent to their own care. Any minor may consent to services related to pregnancy, sexually transmitted infections, and other reportable diseases. A minor 14 or older may consent to voluntary mental health treatment.¹⁷

Emergencies With No Surrogate Available

When a patient is unconscious or otherwise cannot consent and no surrogate is immediately reachable, a physician may perform an emergency medical procedure without consent if a delay would threaten the person’s life or health.¹⁸ That authority does not extend to procedures the patient specifically refused while still conscious or competent.

Patients Who Were Never Competent

A person who has never had the mental capacity to sign an advance directive cannot have a health care agent, because the statute requires a competent principal to make the appointment. Even a court-appointed plenary guardian is treated as a health care representative, subject to the same limits on withholding life-sustaining treatment. The Pennsylvania Supreme Court applied this rule in In re D.L.H., denying a petition by the parents of a profoundly intellectually disabled adult who sought to be appointed as his health care agents so they could refuse ventilator treatment.¹⁹ Because the patient was neither in an end-stage condition nor permanently unconscious, the hospital had an affirmative duty to treat.

Under the Superior Court’s analysis in the same case, a guardian seeking to withdraw life-sustaining treatment from a patient who is not terminally ill or permanently unconscious must petition the court and demonstrate by clear and convincing evidence that the benefits of prolonging life are “markedly outweighed” by the incurable nature of the condition and recurring severe pain, and that extending life would be “inhumane.”²⁰

Patients in State Facilities With No Family

For residents of state facilities who have no family, guardian, or other surrogate available, the Mental Health and Intellectual Disability Act of 1966 (50 P.S. § 4417(c)) lets the facility director serve as decision-maker of last resort. The director may authorize elective surgery and general health care decisions only after obtaining advice from two physicians not employed by the facility.²¹ A facility director may not authorize a DNR order for a person who is not competent and does not have an end-stage medical condition, and must attempt to make the decision the individual would have made if able.²²

The Practical Takeaway

Pennsylvania’s next-of-kin framework guarantees that someone will be authorized to make medical decisions for you, but it does not guarantee it will be the person you would have chosen, and it constrains what that person can do in the most consequential situations. A family member serving as health care representative cannot end life-sustaining treatment unless you are already dying or permanently unconscious, and disputes among relatives in the same tier can stall decisions entirely. Signing a durable health care power of attorney names the decision-maker you want, gives that person the broader authority reserved for agents, and displaces the family list before it ever activates.
