Once a person reaches age 18, they gain certain civil rights under state and federal law. These rights cannot be taken away by parents, support coordinators, or social workers. For some people with disabilities, this is an exciting time to explore independence. Understanding what happens when your special needs child turns 18 can help you prepare for these transitions.
However, not everyone who reaches the age of majority has the mental capacity to make decisions in their best interest. While many parents of children with special needs consider guardianship first, there are alternatives worth exploring before taking such a significant step. For a deeper exploration of these options, see our guide on guardianship alternatives for adult children with disabilities.
Alternatives to Guardianship
Guardianship carries far-reaching implications, so courts consider it a measure of last resort when no alternative interventions are feasible. Here are some options to consider:
Existing Circle of Support
An informal decision-making assistance network of family and close friends works best when the disability is not severe and the person can make most choices independently. If the person respects their support circle’s input and can be guided toward prudent decisions, formal legal processes may be unnecessary.
This approach is not practical, however, for individuals with significant developmental disabilities.
Power of Attorney (POA)
A POA is a legal mechanism granting a third party (the attorney-in-fact) authority to make decisions on behalf of another person (the principal). A durable POA (DPOA) remains in force even if the principal becomes incapacitated.
Key points: A DPOA does not take away the principal’s right to continue making their own decisions. The principal can revoke a DPOA in writing at any time. A DPOA is automatically revoked upon the principal’s death. DPOAs can be specific (health care, education, or financial only).
Representative Payee (RP)
A representative payee is an agency or individual authorized to receive and manage government benefits on behalf of the recipient. The Social Security Administration (SSA) oversees an RP much as a court supervises a guardian. The RP receives the beneficiary’s SSA payments and must document how funds are used for the recipient’s benefit.
Advance Health Care Directive
An advance directive designates who makes medical decisions when you can no longer do so. Two common types are a living will (for terminal illness or vegetative states) and a health surrogate (for ongoing incapacity decisions).
A health surrogate designation must be signed before two witnesses and comes into effect only when the treating doctor determines the individual is incapacitated. The surrogate can make medical decisions, access health records, and apply for benefits.
Trust
A trust is a legal arrangement where a person or institution manages assets for another’s benefit. Three parties are involved: the settlor (who creates and funds the trust), the trustee (who manages the assets), and the beneficiary (who benefits from the trust). Trusts can be revocable or irrevocable.
-
Revocable trust (or living trust): The settlor can move assets in or out and alter trustee/distribution terms while alive. A living trust becomes irrevocable upon the settlor’s death. Advantage: flexibility. Drawback: limits beneficiary access to SSI, Medicaid, public housing, and SNAP.
-
Irrevocable trust: Cannot be altered once established (though Florida and some states allow exceptions). Favored for long-term care planning. For individuals with disabilities, a special needs trust protects government benefit eligibility. The legal considerations in special needs planning include understanding how trusts coordinate with guardianship and other decision-making structures.
Guardianship
Guardianship is a court process determining whether an individual (the ward) has sufficient capacity to make decisions, then assigning rights to a third party. It aims to protect property, welfare, and health.
Guardian Advocate
Guardian advocacy applies to people with specific developmental disabilities: autism, intellectual disability, cerebral palsy, spina bifida, and Prader-Willi syndrome. The individual must lack capacity for some—but not all—decisions needed for self-care and asset management.
Unlike full guardianship, the court need not determine total incapacity, making it a less intrusive option.
Guardian
Guardianship applies to people with dementia, severe developmental disability, or conditions preventing normal functioning. The court determines incapacity based on expert opinion—a more rigorous process than guardian advocacy.
The court may appoint:
- A guardian of the property (manages delegated property rights)
- A guardian of the person (manages delegated personal rights)
- A guardian of both (manages property and personal rights)
The appointed guardian can be a family member, a professional guardian (paid from the ward’s assets), or a public guardian (if available).
Guardianship terminates when the ward’s rights are restored, the ward cannot be located, the ward’s assets are exhausted (for guardians of property only), or upon the ward’s death.
Next Steps
Laws vary by state and county, so it’s important to seek expert clarification on what’s most applicable to your situation. For a comprehensive view of how guardianship decisions fit into the larger special needs planning framework, see our special needs financial planning guide.
