Parent Rights After Your Child Turns 18 in Wyoming

What Changes at 18

Wyoming's age of majority is 18. On that birthday, your child gains the legal right to vote, marry, enter into binding contracts, choose where they live, consent to or refuse medical treatment, and manage their own finances. Every one of those rights transfers from you to them automatically — no court action required, no transition period.

For parents of children with disabilities, the practical consequences hit immediately. Hospitals can't tell you test results. Schools can bar you from IEP meetings. Banks can freeze you out of accounts you helped set up. Your child's therapist can refuse to discuss treatment plans.

None of this requires your child to request it. The default shifts, and institutions follow the law.

What You Still Have

You don't lose everything. Wyoming's surrogate consent statute (W.S. § 35-22-406) places parents third in the priority list — after spouses and adult children — for making medical decisions when a patient lacks capacity and hasn't designated a healthcare agent. In an emergency where your child can't communicate, the hospital can accept your consent for treatment.

Under IDEA, your adult child can invite you to IEP meetings as someone with knowledge or special expertise about them. You don't need any legal documents for this — just your child's verbal or written invitation.

And if your child lives with you, you maintain practical involvement in daily decisions simply through proximity and relationship. The legal authority is gone, but the relationship isn't.

How to Maintain Legal Involvement

The gap between what you lose at 18 and what you can reclaim with voluntary documents is surprisingly small. Five targeted authorizations cover nearly everything:

HIPAA Authorization — Your child signs a form authorizing their healthcare providers to share medical information with you. Without it, doctors are legally prohibited from telling you anything.

Advance Health Care Directive — Names you as healthcare agent under W.S. § 35-22-403. Typically activates when the primary physician certifies your child lacks capacity to make a medical decision.

Durable Financial Power of Attorney — Authorizes you to manage banking, contracts, and benefits under W.S. § 3-9-101. Durable by default in Wyoming since 2018, meaning it survives subsequent incapacity.

Educational Power of Attorney / FERPA Consent — Delegates IEP decision-making authority and authorizes schools to share educational records with you.

Representative Payee Designation — If your child receives SSI, apply directly to the Social Security Administration to manage their benefit payments. No court involvement.

What These Documents Don't Cover

Voluntary authorizations depend on two things: your child's capacity to sign them and third-party willingness to honor them. If your child can't understand what a power of attorney does, they can't legally execute one. And third-party acceptance can still be an issue — particularly with banks that have their own internal policies about POA acceptance.

If your child's impairment is severe enough that voluntary tools don't work, or if they're vulnerable to exploitation by others who might manipulate them into revoking their authorizations, court-ordered guardianship or conservatorship becomes the remaining option.

The Wyoming Adult Guardianship & Alternatives Guide walks through each document with Wyoming-specific requirements and includes a capacity assessment worksheet to help you determine which tools your child can sign.
