Conservatorship vs Guardianship Texas: Why They're Not the Same Thing

Texas Uses These Terms Differently Than Most States

If you're researching guardianship in Texas, you'll quickly notice that "conservatorship" means something completely different here than it does in California, New York, or most other states. This isn't just a naming quirk — the legal structures are entirely separate, governed by different codes, and serve different populations.

Conservatorship: A Family Law Concept for Minors

In Texas, conservatorship is a family law arrangement under the Texas Family Code that governs custody, care, and decision-making for children under 18. When parents divorce or separate, the court establishes a conservatorship — typically a joint managing conservatorship where both parents share rights and duties, or a sole managing conservatorship where one parent holds primary authority.

Every conservatorship in Texas terminates automatically on the child's 18th birthday. It doesn't matter whether the child has a disability — once they reach the age of majority, the Family Code stops applying to them entirely. A conservatorship order cannot be extended, renewed, or modified to cover an adult.

Guardianship: A Probate Law Concept for Incapacitated Adults

Adult guardianship operates under Title 3 of the Texas Estates Code and is handled by the probate court system — a completely separate jurisdiction from the family courts that manage conservatorships.

A guardianship is established through a judicial proceeding where the court finds, by clear and convincing evidence, that an adult lacks the capacity to manage their own personal affairs, financial matters, or both. Unlike conservatorship, guardianship doesn't exist by default — someone must file an application, provide medical evidence of incapacity (via a Physician's Certificate of Medical Examination or a Determination of Intellectual and Developmental Disability), and attend a hearing.

The court can appoint a guardian of the person (responsible for personal care, housing, and medical decisions), a guardian of the estate (responsible for finances and property), or both.

The Critical Gap Between 17 and 18

This distinction creates a practical problem for families of disabled teens. On the day before your child's 18th birthday, you have whatever conservatorship authority the court order gives you — including authority to sign IEP paperwork, authorize medical treatment, or manage bank accounts if the order grants it. The next day, that authority vanishes. Your child is a legal adult, and the law presumes they can make their own decisions regardless of disability.

If you need to re-establish legal authority, you must start the guardianship process from scratch through the probate court. There is no automatic conversion from conservatorship to guardianship, no carryover of rights, and no grace period.

Why This Confusion Matters

The conservatorship-guardianship confusion leads families to make two common mistakes:

Assuming conservatorship continues. Some parents believe their existing custody arrangement somehow extends past 18. It doesn't. Schools, hospitals, and banks will stop recognizing your authority on the 18th birthday. You'll be locked out of medical portals, unable to sign IEP documents at ARD meetings, and legally barred from managing your child's finances.

Searching for the wrong thing. Parents who Google "Texas conservatorship for disabled adult" often find family law resources that don't apply to their situation. The correct search path leads to the Texas Estates Code and probate court — not the Family Code.

Do You Actually Need Guardianship?

Before filing for guardianship, Texas law requires courts to verify that less restrictive alternatives won't work. Many families discover that a combination of voluntary arrangements handles everything they need:

• Supported decision-making agreement lets your adult child designate you as a supporter who helps them gather information and communicate decisions — without giving up any of their legal rights
• Medical power of attorney authorizes you to make healthcare decisions, but only when a physician certifies your child can't
• Durable power of attorney lets your child delegate financial management authority
• Representative payee designation through the SSA lets you manage SSI benefits without court involvement

The Texas Adult Guardianship & Alternatives Guide includes a capability evaluation worksheet that helps families determine which combination of tools fits their specific situation — and whether guardianship is actually necessary.
