Can an Aunt, Uncle, or Sibling Enroll a Child in School or Consent to Medical Care in Arkansas?

Your sister went into rehab and her daughter is living with you now. The child needs to start school Monday and has a dental appointment next week. You are the child's aunt — not a grandparent, not a legal guardian. Can you handle this?

Yes. Arkansas law gives aunts, uncles, and adult siblings real authority here, though the legal basis is slightly different depending on whether you are asking about medical care or school enrollment.

Medical Consent: Adult Siblings Have Named Statutory Authority

Arkansas Code § 20-9-602 lists fourteen categories of people who can consent to medical, surgical, and dental care for a minor. Subsection (8) specifically names adult siblings: "any adult for his or her minor sibling."

This means if you are the child's adult brother or sister, you have explicit statutory authority to consent to medical treatment. The statute does not require a court order, a power of attorney, or the parent's signature. A provider may still ask you to document your age and sibling relationship or review its policy.

For aunts and uncles, the path is subsection (5) — the in loco parentis provision. If you have assumed day-to-day care of your niece or nephew and the parent is absent, you qualify as a person standing "in loco parentis, whether formally serving or not." This gives you the same medical consent authority, but it rests on your caregiving facts rather than a named family relationship.

School Enrollment: In Loco Parentis for Everyone

Unlike the medical consent statute, the school enrollment statute (§ 6-18-202) does not name aunts, uncles, or siblings separately. Instead, § 6-18-208 allows enrollment by a parent, foster parent, legal guardian, or "other responsible person standing in loco parentis."

Whether you are an aunt, uncle, or adult sibling, school enrollment works through in loco parentis. You need to demonstrate that the child lives with you and you are providing primary care. The standard documentation:

• Proof of residency at your address (utility bill, lease)
• The child's birth certificate and immunization records
• The district's residency or caretaker affidavit (ask the registrar for the form)

Most districts process this without difficulty once you present the documentation. If a registrar insists on a court order, ask to speak with a supervisor and reference § 6-18-208's inclusion of in loco parentis caregivers.

Practical Differences Between Aunts/Uncles and Siblings

The practical experience is nearly identical, but there is one legal distinction worth knowing:

Adult siblings (the child's older brother or sister, age 18+) have their own named subsection in § 20-9-602(8) for medical consent. The statute gives you that authority without requiring a court order or POA, but a provider may ask for proof of the sibling relationship or supporting documents.

Aunts and uncles rely on § 20-9-602(5) — the in loco parentis provision — which requires showing that you have assumed care of the child. This is functionally the same authority, but some providers may ask for more documentation because the relationship is one step removed from the named categories.

In both cases, if a parent is available and willing to sign a Power of Attorney, that gives you the cleanest possible paper trail. But it is not required by statute.

What About the Child's Other Parent?

If the child has two legal parents and only one is absent, the other parent retains full legal authority. Your in loco parentis standing or your sibling consent authority supplements the absent parent's role — it does not override the present parent's rights.

If both parents are absent (both incarcerated, both in treatment, one deceased and one missing), your standing under the statute is stronger because there is no competing parental authority. Schools and clinics are more likely to process your enrollment or consent without hesitation.

If one parent objects to the arrangement — actively showing up and demanding the child back — that creates a custody dispute that goes beyond what any consent statute can handle. At that point, you may need to consider a guardianship petition or consult Legal Aid of Arkansas.

Getting Started

The first visit to the school or doctor's office is the hardest. After that, your name is in the system and subsequent visits are routine.
