Wyoming Grandparent Raising Grandchild Legal Rights

The Short Answer Most Grandparents Don't Want to Hear

A grandparent raising a grandchild in Wyoming does not gain legal custody or health-care decision authority merely because the child lives in the grandparent's home. A child who qualifies under McKinney-Vento has separate federal enrollment rights. Outside that rule, a caregiver generally needs a court order or a parental authorization that the institution accepts. Without a court order or valid parental delegation, you are, in the eyes of schools and clinics, a third party.

This isn't a technicality. It determines whether a registrar will enroll the child, whether a doctor will see them for a wellness visit, and whether you can sign a permission slip for a field trip.

What You Can Do Without a Court Order

Wyoming law doesn't completely leave informal caregivers without options. The level of authority depends on parental cooperation:

If a parent is available and willing to sign, a notarized parental consent letter can authorize you to handle school enrollment, medical appointments, and daily decisions. This is a contractual agreement — the parent voluntarily delegates specific powers to you. Schools and clinics are not legally required to accept it, but many do when the document is properly executed with notarization and witness signatures.

If the child qualifies under McKinney-Vento — lacking a fixed, regular, and adequate nighttime residence, including when sharing housing because of loss of housing, economic hardship, or a similar reason — federal law requires immediate school enrollment without guardianship papers. The school's homeless education liaison processes this — you usually have to ask for them by name.

For sufficiently urgent care, W.S. § 14-1-101(b)(iii) allows a minor to consent to health care treatment as an adult when the parents or guardian cannot with reasonable diligence be located and the need for treatment is sufficiently urgent to require immediate attention. This does not give a caregiver general consent authority for routine care.

What Requires a Court Order

Certain decisions and institutions will not move forward without formal legal authority:

• Elective surgeries and invasive medical procedures: Nearly all require consent from a parent or court-appointed guardian, not an informal caregiver.
• WYDOT driver's permit applications: Under W.S. § 31-7-112, a parent or guardian having custody must sign. If there is no parent or guardian, the minor may petition the circuit court judge in the county of residence; the judge may sign after finding the minor sufficiently mature to handle driving responsibilities.
• U.S. passport applications for children under 16: Under 22 C.F.R. § 51.28, both parents or guardians generally must consent; exceptions apply, including when one parent has sole custody.
• Adding the child to your health insurance: Most insurers require a court order establishing legal guardianship.
• Court-appointed authority: A temporary guardian appointed under W.S. §§ 3-2-301 through 3-2-303 has authority for the educational, medical-care, and dental-care decisions specified in the statute.

Wyoming's Temporary Guardianship for Relatives

The path specifically designed for grandparents and relatives is temporary guardianship under W.S. §§ 3-2-301 through 3-2-303. To qualify, you must be at least 18, be the child's primary physical custodian, and be a qualifying relative other than a natural parent or legal guardian (stepparent, grandparent, great-grandparent, sibling, stepsibling, half-sibling, uncle, or aunt).

The court order grants authority over school enrollment, educational decisions, and medical and dental consent. An ex parte order without notice to the parents requires the court to find by a preponderance of the evidence from the petition and any testimony that it is in the child's best interest, is not detrimental to others, and that no other person appears to have authority and willingness to act. Except upon a showing of good cause, an ex parte order lasts no more than one year. It can be renewed.

This is less than full guardianship — it doesn't give you authority over the child's estate or permanent custody — but it covers the two things most grandparents need immediately: school and healthcare.

Full Guardianship

For long-term arrangements, full minor guardianship under W.S. §§ 3-2-101 through 3-2-109 can provide legal and physical custody until the child turns 18 or the court terminates the guardianship. It requires a district court petition (GMCP packet), service on each living parent whose rights have not been terminated, a court hearing, and a $160 filing fee (waivable with an Affidavit of Indigency). If the parents oppose the guardianship, the court must also find that they are unfit or unable to care for the child, not merely that another caregiver would be better.

Full guardianship carries more weight — and more procedural requirements — than temporary guardianship. Legal Aid of Wyoming (1-877-432-9955) provides free assistance to eligible caregivers filing either type.

The Rights You Already Have

Even without a court order, grandparents raising grandchildren can:

• Apply for Medicaid, Kid Care CHIP, SNAP, and POWER benefits on behalf of the child through the Wyoming Self-Service Portal
• Contact Wyoming 211 for referrals to kinship support services
• Access the Older Relative Caregiver (ORC) program through the Aging Division if you're 55 or older and in a participating county (Johnson, Laramie, or Sheridan)
• File for temporary or full guardianship pro se (without an attorney) using the court's self-help packets
