Arkansas consent laws for medical treatment are set out primarily in Arkansas Code 20-9-602, which lists more than a dozen categories of people who can authorize care recommended by a licensed physician, either orally or in writing.1Justia. Arkansas Code 20-9-602 – Consent Generally – Definition Adults consent for themselves. When the patient is a minor or cannot make decisions, the statute names family members, guardians, and other caregivers who can step in, and separate rules cover emergencies, advance directives, and specific conditions like sexually transmitted infections.
Who Can Consent for Themselves
Any adult in Arkansas can consent to their own medical or surgical treatment. So can anyone who is married, regardless of age, and any emancipated minor.1Justia. Arkansas Code 20-9-602 – Consent Generally – Definition
Arkansas also recognizes a mature-minor rule. An unemancipated minor who is not married can still consent on their own behalf if they show “sufficient intelligence to understand and appreciate the consequences of the proposed surgical or medical treatment or procedures.”1Justia. Arkansas Code 20-9-602 – Consent Generally – Definition There is no age cutoff written into the statute. The judgment falls to the treating provider and is made case by case.
One more baseline point matters here. Arkansas Code 20-9-601 states that refusing medical care, on its own, does not make a person “of unsound mind.”2Justia. Arkansas Code 20-9-601 – Definition A provider cannot treat a “no” as proof that the patient lacks capacity and then look for someone else to say yes.
Who Can Consent for Someone Else
When the patient cannot consent personally, Arkansas Code 20-9-602 authorizes a wide range of substitute decision-makers.1Justia. Arkansas Code 20-9-602 – Consent Generally – Definition The list is broader than most people expect:
- A parent (adult or minor) for a minor child or an adult child of unsound mind. This includes biological, adopted, step, foster, and preadoptive children, though foster and preadoptive children must not be in the custody of the Department of Human Services for this provision to apply.
- A person acting in loco parentis, a court-appointed guardian, conservator, or custodian, for the person in their charge.
- A spouse, for a married person of unsound mind.
- An adult child, for a parent of unsound mind.
- An adult sibling, for a minor sibling or an adult sibling of unsound mind.
- A maternal grandparent, and a paternal grandparent if the father holds consent authority, during a parent’s absence, for a minor grandchild or an adult grandchild of unsound mind.
Each category stands on its own. The statute does not put these decision-makers in a strict priority order, which means a spouse and an adult child both have legal authority to consent for an incapacitated parent or partner. When family members disagree, a court-appointed guardian’s authority generally prevails.
Consent under this statute does not have to be in writing. Oral consent is legally valid.1Justia. Arkansas Code 20-9-602 – Consent Generally – Definition Providers still document consent in the record and use signed forms for surgical and invasive procedures, but the statute itself does not require a signature.
Federal law reinforces this framework on the records side. Under HIPAA, anyone authorized by state law to make healthcare decisions for another person is treated as that person’s “personal representative” and has the right to access their medical information.3HHS.gov. Personal Representatives A spouse consenting for an incapacitated partner in Arkansas therefore also has the right to receive that partner’s records and speak with the treating providers.
What Informed Consent Has to Cover
Getting a yes from the right person is only half of what the law requires. The consent must be informed. The provider needs to explain the nature of the proposed treatment, its risks and benefits, reasonable alternatives with their risks, and the likely consequences of doing nothing.
This has legal teeth. If a provider fails to disclose material risks and the patient suffers a harm they would have avoided by choosing differently, the provider can face liability for lack of informed consent. The treatment itself does not have to be performed negligently. The failure is in not giving the patient what they needed to decide.
Standardized consent forms are common, but the form is not the requirement. The conversation is. A signed page with no real explanation behind it is weak protection for the provider and no protection at all for the patient.
Consent in Emergencies
Arkansas Code 20-9-603 provides for implied consent when a patient’s condition demands immediate treatment and no authorized person is available to give express consent.4Justia. Arkansas Code 20-9-603 – Implied Consent The statute also addresses the harder case where someone with consent authority previously refused, but the patient’s condition has since deteriorated in a material and morbid way. In that situation, providers can act.
For children in DHS custody, foster parents and preadoptive parents can consent to treatment in emergencies, and they must notify DHS afterward for hospital admissions and discharges.1Justia. Arkansas Code 20-9-602 – Consent Generally – Definition That arrangement prevents delays while a caseworker is tracked down.
Federal law layers on top of the state rules. The Emergency Medical Treatment and Labor Act requires every Medicare-participating hospital with an emergency department to screen anyone who arrives seeking treatment for an emergency condition and to provide stabilizing care, regardless of ability to pay or insurance.5Centers for Medicare & Medicaid Services (CMS). Emergency Medical Treatment and Labor Act (EMTALA) Payment questions cannot delay the screening exam or stabilization. A hospital also satisfies EMTALA if it offers the required treatment, explains the risks and benefits, and the patient or their representative refuses to consent.6Office of the Law Revision Counsel. 42 US Code 1395dd – Examination and Treatment for Emergency Medical Conditions and Women in Labor The hospital owes the offer, not forced treatment.
Minor Consent for STI Care
Arkansas Code 20-16-508 allows a minor who believes they have a sexually transmitted infection to consent to medical care and services for that condition on their own.7Justia. Arkansas Code 20-16-508 – Treatment of Minors Parental notification and approval are not required. The rule exists so that fear of a parent finding out does not keep minors away from care for infections that carry ongoing public health risks.
Planning Ahead With Advance Directives
The default consent hierarchy applies when someone becomes incapacitated without having planned ahead. Advance directives change that default by letting you choose your decision-maker and record your wishes in advance.
Living Wills
Arkansas’s Rights of the Terminally Ill or Permanently Unconscious Act, at Arkansas Code 20-17-201 through 20-17-218, lets any adult of sound mind sign a declaration governing the withholding or withdrawal of life-sustaining treatment.8FindLaw. Arkansas Code 20-17-202 – Declaration Relating to Use of Life-Sustaining Treatment The declaration must be signed by the person making it, or by someone else at their direction, and either notarized or witnessed by two individuals who are not related by blood, marriage, or adoption and not entitled to any portion of the estate. Once executed, it goes into the medical record and stands as clear and convincing evidence of the person’s wishes. It typically addresses CPR, mechanical ventilation, tube feeding, and similar interventions in a terminal or permanently unconscious state.
Healthcare Power of Attorney
A healthcare power of attorney designates a person, sometimes called a healthcare proxy or agent, to make medical decisions for you when you cannot. This is often more practical than a living will alone because no written document can anticipate every scenario a doctor might raise. The proxy adapts to the situation, guided by your known values. Arkansas law allows healthcare powers of attorney to be either notarized or witnessed by two witnesses. Many people sign both documents so the proxy has decision-making authority and written guidance.
The Right to Refuse Treatment
The U.S. Supreme Court has recognized a constitutionally protected liberty interest in refusing unwanted medical treatment under the Due Process Clause of the Fourteenth Amendment.9Constitution Annotated | Congress.gov | Library of Congress. Right to Refuse Medical Treatment and Substantive Due Process In Cruzan v. Director, Missouri Department of Health, a majority of the Justices indicated that a competent person has a constitutionally protected right to refuse even lifesaving treatment, including artificially delivered food and water.
Arkansas law aligns. Because refusing care does not itself make a person of unsound mind, a competent adult can decline any treatment a doctor recommends, and the provider must respect that decision.2Justia. Arkansas Code 20-9-601 – Definition The harder cases involve incapacitated patients whose wishes were never written down. A properly executed advance directive is the clearest way to keep that decision your own.
When a Provider Treats Without Valid Consent
Treating without proper consent exposes a provider to two different kinds of claims, and the distinction matters.
Lack of informed consent is a form of medical malpractice. It applies when the provider obtained some consent but failed to disclose the risks, benefits, and alternatives a reasonable patient would want to know. The patient has to show that, with full information, they would have declined and that the treatment was a substantial factor in the injury. The procedure itself does not have to be performed negligently.
Battery is a separate and more serious claim. It applies when there was no consent at all, when the provider performed a substantially different procedure than the one authorized, or when one provider was substituted for another without permission. Battery is an intentional tort. It typically falls outside malpractice insurance and can support punitive damages. The recognized exception is implied consent in a genuine emergency where the patient cannot communicate and no authorized decision-maker is available.
For patients, the practical lesson is to know who has authority to speak for you and, ideally, to put those choices in writing before you need them. For providers, the lesson is that the consent conversation, documented in the record, is what the law actually requires.
