Under Arkansas consent laws for medical treatment, a licensed physician can proceed when the patient — or another person authorized by Arkansas Code 20-9-602 — agrees to the recommended care, either orally or in writing.1Justia. Arkansas Code 20-9-602 – Consent Generally – Definition The statute lists more than a dozen categories of people who can consent, and separate rules govern minors, emergencies, and adults who cannot speak for themselves. Knowing which category applies, and what the provider still has to disclose, is what keeps a “yes” legally meaningful.
Who Can Legally Give Consent
Arkansas Code 20-9-602 reaches well beyond the patient and immediate parents. Any adult can consent for themselves. A married person of any age can consent for themselves and, if their spouse is of unsound mind, for the spouse. Emancipated minors consent as adults do.1Justia. Arkansas Code 20-9-602 – Consent Generally – Definition
For someone else’s care, authority runs through family and legal relationships. A parent — adult or minor — can consent for a minor child or an adult child of unsound mind, and the definition of “child” includes biological, adopted, step, foster, and preadoptive children (foster and preadoptive children only when not in the custody of the Department of Human Services). An adult can consent for a minor sibling or an adult sibling of unsound mind. An adult child can consent for a parent of unsound mind. During a parent’s absence, a maternal grandparent — and a paternal grandparent if the father holds consent authority — can consent for a minor grandchild or an adult grandchild of unsound mind. Persons standing in loco parentis, along with court-appointed guardians, conservators, and custodians, can consent for anyone in their care.1Justia. Arkansas Code 20-9-602 – Consent Generally – Definition
Two details often surprise people. First, the statute does not require writing. Oral consent is legally valid, though providers routinely document it and use signed forms for surgical or invasive procedures. Second, refusing care does not, by itself, make someone “of unsound mind.” Arkansas Code 20-9-601 says so directly, and a provider cannot treat a competent patient’s “no” as proof they lack capacity.2Justia. Arkansas Code 20-9-601 – Definition
What Makes Consent “Informed”
Having the right person say yes is only half of it. For consent to be legally meaningful, the provider has to give the patient enough information to make a real decision: the nature of the proposed treatment, the risks and benefits, reasonable alternatives and their risks, and what happens if the patient does nothing.
This has legal teeth. If a provider fails to disclose a material risk and the patient suffers harm they would have avoided by choosing differently, the provider can be liable for lack of informed consent — even if the procedure itself was performed correctly. The failure is in the conversation, not the technique. A signed form where no one actually explained the risks is weak protection for the provider and no protection at all for the patient.
Consent Rules for Minors
Arkansas is more flexible than many states about minors making their own medical decisions, and the rules depend on the minor’s circumstances.
Married, Emancipated, and Minor Parents
Married minors and emancipated minors consent for themselves. A minor who is already a parent can also consent to treatment for their own child, which matters when a teenage mother needs to authorize care for her baby.1Justia. Arkansas Code 20-9-602 – Consent Generally – Definition
The Mature-Minor Standard
For an unemancipated, unmarried minor, Arkansas allows self-consent when the minor shows “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 fixed age. The call falls to the provider and depends on the minor and the specific treatment. A thoughtful 15-year-old may clearly qualify for one decision and not another.
Sexually Transmitted Infections
A separate statute, Arkansas Code 20-16-508, lets a minor who believes they have a sexually transmitted infection consent to care for that condition without parental notification or approval.3Justia. Arkansas Code 20-16-508 – Treatment of Minors The rule exists so public-health concerns about untreated infection don’t collide with a minor’s reluctance to involve a parent.
When a Minor Can’t Consent
If the minor doesn’t fit any self-consent category, the family hierarchy in 20-9-602 takes over: parents, then persons in loco parentis, guardians, grandparents during a parent’s absence, and adult siblings. The breadth of the list matters most when a child lives with a grandparent or older sibling and a parent isn’t reachable.1Justia. Arkansas Code 20-9-602 – Consent Generally – Definition
Consent in Emergencies
Emergencies create the hardest consent problems. The patient may be unconscious, a parent unreachable, and the clock running. Two legal frameworks apply.
Arkansas Implied Consent
Arkansas Code 20-9-603 recognizes that consent can be implied when a patient’s condition demands immediate treatment and no authorized person is available to give express consent. The statute also addresses the harder case where an authorized person previously refused consent but the patient’s condition has since deteriorated, allowing providers to act when a material and morbid change has occurred.4Justia. Arkansas Code 20-9-603 – Implied Consent
Foster and Preadoptive Parents
For children in DHS custody, foster parents and preadoptive parents can consent to treatment in emergency situations, which avoids delays while someone tries to reach a caseworker. Foster and preadoptive parents who consent to a hospital admission or discharge must notify DHS.1Justia. Arkansas Code 20-9-602 – Consent Generally – Definition
EMTALA
Federal law sits on top of all of this. The Emergency Medical Treatment and Labor Act requires every Medicare-participating hospital with an emergency department to screen anyone who arrives seeking emergency care and provide stabilizing treatment, regardless of ability to pay or insurance status.5Centers for Medicare & Medicaid Services (CMS). Emergency Medical Treatment and Labor Act (EMTALA) The hospital cannot delay screening or stabilization to ask about payment. EMTALA also addresses refusal: a hospital meets its obligation if it offers the required treatment and explains the risks and benefits but the patient or their representative declines.6Office of the Law Revision Counsel. 42 US Code 1395dd – Examination and Treatment for Emergency Medical Conditions and Women in Labor The hospital has to offer care; it cannot force it.
Consent for Incapacitated Adults
When an adult cannot make their own medical decisions, Arkansas Code 20-9-602 authorizes several substitute decision-makers: a spouse, a parent, an adult child, an adult sibling, grandparents during a parent’s absence, and court-appointed guardians, conservators, or custodians.1Justia. Arkansas Code 20-9-602 – Consent Generally – Definition Each category stands independently. The statute doesn’t set a strict priority among them, so in practice a spouse and an adult child both carry legal authority. When family members disagree, a court-appointed guardian’s authority generally prevails.
Living Wills and Healthcare Powers of Attorney
The default hierarchy applies only when the patient hasn’t planned ahead. 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 execute a declaration governing the withholding or withdrawal of life-sustaining treatment. The declaration must be signed and either notarized or witnessed by two individuals who are not related to the person by blood, marriage, or adoption and are not entitled to any portion of the estate.7FindLaw. Arkansas Code 20-17-202 – Declaration Relating to Use of Life-Sustaining Treatment Once executed, the declaration becomes part of the medical record and serves as clear and convincing evidence of the person’s wishes.
A healthcare power of attorney does something different. Rather than listing specific treatments, you name a healthcare proxy to make medical decisions when you can’t. The proxy can adapt to circumstances no document could anticipate. Many people execute both, so the proxy has both authority and written guidance.
The Right to Refuse Treatment
A competent adult in Arkansas can decline any treatment, even one a doctor strongly recommends. Arkansas Code 20-9-601 makes clear that refusal alone is not evidence of an unsound mind.2Justia. Arkansas Code 20-9-601 – Definition The U.S. Supreme Court has also recognized a constitutionally protected liberty interest in refusing unwanted medical treatment under the Due Process Clause of the Fourteenth Amendment; 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.8Constitution Annotated | Congress.gov | Library of Congress. Right to Refuse Medical Treatment and Substantive Due Process
The harder question arises when the patient is incapacitated. Without a living will or healthcare proxy, the state’s interest in preserving life can collide with the family’s view of what the patient would have wanted. That is the strongest practical reason to execute an advance directive while clearly competent.
When a Provider Treats Without Valid Consent
Treating without valid consent exposes a provider to two different kinds of claims, and the distinction matters.
A lack-of-informed-consent claim arises when the provider got some form of consent but failed to disclose the risks, benefits, and alternatives a reasonable patient would want to know. The patient has to show that, fully informed, they would have declined and that the treatment caused their injury. The procedure itself does not have to be negligent; even a perfectly executed treatment can produce liability if the pre-treatment conversation fell short.
Battery is more serious. It applies when there was no consent at all, when the provider performed a substantially different procedure than the one authorized, or when a different provider was substituted without permission. As an intentional tort, battery usually falls outside malpractice insurance and can expose the provider to 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 providers, the practical lesson is to document the consent conversation and not just the signature. For patients, the two claims have different elements, different defenses, and potentially very different outcomes, so it is worth knowing which one fits the facts.
