Adult Children with Disabilities

The eighteenth birthday is supposed to be a celebration. For families raising a child with a disability it is also a legal cliff, and most parents find the edge by accident: a nurse who will not give you the test results, a bank that will not talk to you, a school that suddenly needs your adult child's written permission to speak with you. Nothing about your child changed that morning. Florida's view of who decides did.

What changes on the eighteenth birthday

• Your authority as a natural guardian ends. Your child is an adult who makes their own medical, financial and educational decisions.
• Doctors, schools and colleges need your child's permission to speak with you.
• Social Security reviews a child recipient under the adult disability rules, which ask about the ability to work.
• Your income and resources stop counting against your child the month after the birthday. Many families see the check go up.

First question: can your child sign?

Many young adults with disabilities can sign their own documents, with support. If yours understands what they are signing, the least restrictive path is also the fastest: a durable power of attorney signed before two witnesses and a notary, a designation of health care surrogate signed before two subscribing witnesses, a HIPAA release, and written permission for the school to keep talking with you. No court, no judge, no annual reporting. It is the same set we recommend for any eighteen year old leaving for college.

Guardian advocacy, Florida's lighter path

When your child cannot make some decisions safely, Florida offers guardian advocacy under section 393.12. A guardian advocate can be appointed without an adjudication of incapacity, and the court delegates only the decisions your child lacks the ability to make. Everything else stays your child's own.

It is available for a developmental disability as Florida defines it: intellectual disability, cerebral palsy, autism, spina bifida, Down syndrome, Phelan-McDermid syndrome or Prader-Willi syndrome, appearing before age eighteen. Your child is appointed an attorney within three days. The person asking to serve does not need an attorney unless the court requires it or the petition asks for property powers beyond acting as representative payee.

When full guardianship is the answer

If the disability is not one of those seven conditions, or it began after age eighteen, the route is a guardianship under chapter 744: a petition to determine incapacity, an examining committee of three professionals, an attorney for your child, and a court that supervises the guardian with annual reports. It is the right tool sometimes, and it is heavier, which is why we look at the lighter paths first.

The money rules that undo good intentions

Supplemental Security Income allows about $2,000 in countable resources, and the 2026 federal benefit is $994 a month for an individual, a figure that changes every January. A grandmother's $10,000 bequest, a life insurance form with your child's name on it, or a settlement paid directly to your child can suspend the check and disturb the Medicaid that comes with it. No one in those stories did anything wrong. They just did it in the child's name.

The third-party special needs trust: the one you build

This is the trust you fund with your money, never your child's. It pays for what benefits do not cover, the trustee holds the assets rather than your child, and because your child never owned the money there is no repayment to the state. You name who receives what is left. Your will, your trust and every beneficiary form should point here instead of to your child by name.

Tell the grandparents. A loving beneficiary designation signed at a bank branch has undone more special needs plans than any other document.

First-party and pooled trusts: the ones that fix a problem

When money is already in your child's name, from a settlement, a direct inheritance or back pay, a first-party special needs trust holds the assets of a disabled person under sixty-five, established by your child, a parent, a grandparent, a legal guardian or a court. The tradeoff is the payback: at your child's death the state is repaid up to what Medicaid spent.

A pooled trust does the same work through a nonprofit managing many subaccounts together, which suits smaller amounts. Federal law sets no age limit there, but whether funding one at sixty-five or older triggers a Florida transfer penalty is genuinely unsettled. Ask us before anything moves.

ABLE accounts, the everyday tool

Florida's program is ABLE United. The money is spent on qualified disability expenses, the first $100,000 does not count against the SSI resource limit, and ABLE savings are disregarded for Medicaid. For 2026 the annual contribution limit is $20,000, and a working account owner may add their own earnings up to a federal limit. Since January 1, 2026, eligibility reaches disabilities that began before age 46, raised from age 26.

Money withdrawn for housing has to be spent in the month it comes out or it counts as a resource, and these figures change most years. The account is the checking account of the plan. The trust is the vault.

Waiver services, and your own plan

In Florida, the Agency for Persons with Disabilities administers the iBudget waiver. After APD finds a person eligible, APD may place the person in pre-enrollment for waiver services if immediate enrollment is not available. Waiver offers are made according to statutory priority categories and available funding, rather than simply by application date, and many families experience long waits. Apply as soon as eligibility is reasonably established, and keep APD informed of material changes in diagnosis, functioning, caregiving, safety, housing, or service needs; updated records can support eligibility and a request to reassess priority, but they do not by themselves guarantee enrollment.

Separately, for Medicaid long-term-care planning, federal law generally exempts transfers to a parent's blind or disabled child, and transfers to a trust established solely for that child's benefit, from the Medicaid transfer-penalty rules. An outright transfer may avoid a penalty for the parent but can jeopardize the child's SSI or means-tested Medicaid if the funds become the child's countable resource. For that reason, a properly drafted third-party special-needs trust is often the safer option, but the choice and trust terms should be reviewed with a Florida elder-law and special-needs-planning attorney before any transfer.

The letter of intent

A letter of intent is not a legal document, but it may be the most practical document you leave for the people caring for your child.

It explains the things a will or trust cannot capture: what your child's typical day looks like, how they communicate, what helps them feel safe, what causes stress, which routines matter, who their doctors and providers are, and who knows them well. It can also describe your hopes for their housing, relationships, activities, health care, education or work, and overall quality of life.

Write it in plain, practical language. Include enough detail that a new caregiver, trustee, guardian, or family member could understand your child as a person, not just as a diagnosis or a list of services.

Review and update it at least once a year, and whenever there is a major change in health, medications, school, work, benefits, living arrangements, or support people. A trustee may manage money, but they cannot make good decisions about your child's needs and preferences without this kind of guidance.

Before the eighteenth birthday

• Decide which path fits: signed documents, guardian advocacy, or a chapter 744 guardianship.
• Gather the diagnosis, the school evaluations and the records that describe how your child functions.
• If a court filing is needed, start at seventeen years and six months.
• Apply for Supplemental Security Income and prepare for the age eighteen review.
• Apply to the Agency for Persons with Disabilities and get on the pre-enrollment list.
• Open an ABLE United account.
• Redirect your will, your trust and every beneficiary form to the special needs trust.
• Name a trustee, a successor trustee, and who should serve as guardian advocate after you.
• Write the letter of intent.
