Your Child Is Turning 18: Decision-Making Options for Florida Parents of Adults with Disabilities

At 18, a parent's automatic authority ends. Florida law offers a range of tools to continue helping, and requires the least restrictive one that works.

What Changes at Age 18

While your child is a minor, you are the natural guardian and can make decisions for them. At 18, the law treats your child as an adult, and that automatic authority ends. Fla. Stat. §§ 744.301(1), 743.07(1). Doctors, banks, schools, and agencies may no longer share information with you or accept your decisions unless you have legal authority from one of two sources: documents your adult child signs naming you to help, or a court order appointing you.

One way to picture it: documents are like a house key your adult child hands you; they keep a key too and decide who else gets one. A court appointment is a key the court hands you; the court keeps a copy and checks each year how it is being used.

Florida law requires the least restrictive option that meets the adult child's needs. A court may not appoint a guardian if documents or other arrangements are enough, and any order must be the least restrictive appropriate alternative. Fla. Stat. §§ 744.331(6)(b), 744.2005(3). That principle organizes everything below: the options form a ladder, and the law starts at the bottom rung.

Two related points are worth knowing at the outset. If your child received a settlement or other property managed through a guardianship of a minor, that guardianship ends at 18; if the child cannot then manage the property, a petition to determine incapacity is required, and the existing guardian should ask the court for leave to keep control of the assets until it is resolved. Fla. Stat. § 744.521. And turning 18 does not necessarily end a parent's obligations: a court may require a parent to support a dependent adult child whose mental or physical incapacity began before majority. Fla. Stat. § 743.07(2).

Options That Do Not Require Court

These work only if your adult child understands what they are signing. The adult child keeps all of their rights under each.

• Supported decision-making agreement. Your adult child keeps making their own decisions; you can receive information (including medical information) and help communicate. You cannot sign or decide for them. The agreement is executed in the manner of a power of attorney. Fla. Stat. § 709.2209.
• Durable power of attorney. Names you as agent to handle the financial and benefits matters listed in the document, such as banking and government benefits applications. The agent acts only within the powers expressly granted, and certain powers (such as gifts, trusts, and beneficiary designations) must be separately initialed. It is signed before two witnesses and a notary and takes effect when signed; Florida has not permitted “springing” powers created since October 1, 2011. Fla. Stat. §§ 709.2201, 709.2202. Your adult child keeps the power to act too; the agent's authority runs alongside it.
• Health care surrogate designation. Names you to make health care decisions and receive medical information, and allows you to apply for benefits such as Medicaid. It is signed before two witnesses; the surrogate cannot be a witness, and at least one witness may not be a spouse or blood relative. It can take effect immediately, and while your adult child can make their own decisions, those decisions control. Fla. Stat. §§ 765.202, 765.204.
• Declaration naming preneed guardian. Names who your adult child wants as guardian if a guardianship is ever needed. It gives no authority now, but it creates a rebuttable presumption that the named person serves, so the court must generally honor it later. Fla. Stat. § 744.3045. Your adult child's competence at the time of signing is the core question if the declaration is ever challenged.

Options That Require Court

• Guardian advocacy. For an adult with a qualifying developmental disability who can make some decisions but not others. Under the statute, a qualifying disability is one such as intellectual disability, cerebral palsy, autism, spina bifida, Down syndrome, Phelan-McDermid syndrome, or Prader-Willi syndrome, manifesting before age 18 and expected to continue indefinitely. Fla. Stat. §§ 393.063, 393.12. The court gives you authority only over the specific areas where your adult child needs help; they keep every other right. There is no finding that your adult child is incapacitated, and no examining committee. The standard of proof is clear and convincing evidence. If your adult child receives services from the Agency for Persons with Disabilities, the State has already found a developmental disability. If an adult lacks the ability to make decisions in every area, guardian advocacy is not available and formal guardianship is required.
• Limited guardianship. The court finds that your adult child cannot exercise certain rights and gives you authority over only those rights. This requires an adjudication of incapacity by clear and convincing evidence, an examination by a three-member committee, and a hearing. Fla. Stat. § 744.331.
• Plenary guardianship. For an adult who cannot exercise any of the rights the court can delegate. The process is the same as limited guardianship; you make all delegable decisions, and your adult child keeps certain basic rights the law protects from delegation. Fla. Stat. § 744.3215(1).
• Standby (backup). With a guardian advocacy or guardianship, you can ask the court to name a backup who takes over if you can no longer serve.

In every court case, the court appoints a separate attorney for your adult child whose job is to represent your adult child's own wishes, even if those wishes are to oppose the petition. Fla. Stat. §§ 744.331(2), 393.12(5). That is a normal part of the process, not a sign anything has gone wrong.

Comparing the Options

Court options carry court costs, including filing fees and the fee of the attorney the court appoints for the adult child; guardianship also carries examining committee fees. Managing property through the court adds a bond or a restricted depository account, an inventory, yearly accountings, and clerk audit fees.

How the Options Interact with Existing Documents

The tools above are not isolated; Florida law specifies how they work together, and the interactions matter.

• Filing a petition suspends an agent's authority, with a family exception. Filing a petition to determine incapacity or to appoint a guardian advocate suspends the authority of an agent under a power of attorney, but not if the agent is the adult's parent, spouse, child, or grandchild, unless a separate verified motion is also filed. Health care provisions continue. Fla. Stat. §§ 709.2109(3), 744.3202.
• A finding of incapacity ends a power of attorney unless the court preserves it. If any power should survive, the order must affirmatively state which powers remain. Fla. Stat. § 709.2109(1).
• A health care surrogate's authority generally survives. If a valid designation exists when a guardian is appointed, the order must state what authority the guardian and the surrogate each keep; unless the court orders otherwise, the surrogate's health care authority continues. Fla. Stat. §§ 744.3115, 765.205(3).
• Guardian advocacy defers to sufficient documents. The court must determine whether an existing advance directive or durable power of attorney sufficiently addresses the adult's needs; if it does, no guardian advocate may be appointed, and if one is appointed anyway, the agent's powers may be suspended only if the instrument is invalid or abused. Fla. Stat. § 393.12(7).

Government Benefits and Money

Many adults with disabilities receive Supplemental Security Income (SSI) and Medicaid. These points apply whichever option you choose. Dollar figures change each year, so current amounts should be confirmed before acting.

• SSI and Medicaid. SSI is based on financial need. The adult child can own no more than $2,000 in countable assets; the home, one car, and personal belongings do not count. In Florida, receiving any SSI makes the adult child eligible for Medicaid automatically.
• Housing and gifts. If the adult child lives with you rent-free, Social Security treats the free housing as income and reduces the SSI payment. Cash given directly to the adult child also reduces it. Money left to the adult child outright, such as an inheritance or settlement, can affect eligibility.
• Representative payee. Social Security can appoint you to receive and manage the adult child's benefits. This is handled by the Social Security Administration, not the court, and courts recognize it as a less restrictive alternative that in some cases avoids the need for a guardianship. Fla. Stat. § 744.331(6)(b). You keep the benefits in a separate account and use them for the adult child's needs. A yearly report to Social Security is usually required, though parents whose adult child lives with them are generally excused.
• Special needs trust. A trust that holds money for the adult child's extra needs without counting against SSI or Medicaid. 42 U.S.C. § 1396p(d)(4). A trust funded with your money, often through your own estate plan, is not counted as the adult child's asset. A trust funded with the adult child's own money must repay Medicaid at the adult child's death; a nonprofit “pooled” trust is another option for the adult child's own money. A parent can set up these trusts without a guardianship; a guardian, by contrast, needs court approval to create or fund a trust with the ward's own money. Fla. Stat. § 744.441.
• ABLE account. A tax-advantaged savings account owned by the adult child, for a person whose disability began before age 46 (a threshold that took effect in 2026). 26 U.S.C. § 529A; Fla. Stat. § 1009.986. You, other family members, or the adult child can contribute up to a yearly limit. The account does not count against Medicaid, and it does not count against SSI unless it grows above $100,000. It can pay housing costs without reducing SSI, and Florida does not seek Medicaid recovery from the account at death. A parent can open it without a guardianship.
• Fewer court reports. If you are a guardian or guardian advocate and are also representative payee, and the adult child's only income is Social Security, the court generally excuses the yearly accounting. Fla. Stat. § 744.3678(5).

What the Court Process Looks Like

1. The petition is prepared and filed, along with the application to serve. In guardian advocacy, the verified petition must state the exact areas in which the adult lacks decision-making ability, the areas the adult can handle, any existing documents, and why they are insufficient. Fla. Stat. § 393.12(3). The prospective guardian completes a credit check and fingerprint background screening unless the court waives them. Fla. Stat. §§ 744.3125, 744.3135.
2. The court appoints an attorney for the adult child (in guardian advocacy, within three days of filing), and the adult child and close family members receive notice. Fla. Stat. §§ 393.12(4)–(5), 744.331(2).
3. Guardianship only: a three-member examining committee evaluates the adult child and files reports; if a majority finds no incapacity, the petition is dismissed. Fla. Stat. § 744.331(3)–(4).
4. A hearing is held. The adult child generally attends, and the standard of proof is clear and convincing evidence. In guardian advocacy, the court considers support plans, individual education plans, and professional reports.
5. If the court grants the petition, the order states its findings, including the specific areas of authority and whether less restrictive alternatives suffice; the guardian takes an oath, and the court issues letters confirming the authority. Fla. Stat. §§ 393.12(8), 744.331(6), 744.345.
6. The guardian completes an education course (a minimum of eight hours) within four months, unless the court waives it. Fla. Stat. § 744.3145.

Who May Serve

A guardian advocate must meet the same qualifications as a guardian. Fla. Stat. § 393.12(10). In general, a person 18 or older who is a Florida resident may serve, and a nonresident may serve if related to the adult child by blood, marriage, or adoption within the categories the statute lists. Disqualifications include a felony conviction, certain disqualifying offenses, a judicial finding of abuse, abandonment, or neglect of a child, incapability of performing the duties, and conflicts of interest. Fla. Stat. § 744.309. The court must give preference to relatives, though the preference is not binding, and the court also considers the adult child's own expressed wishes about who should serve. Fla. Stat. § 744.312.

Your Duties If Appointed

• File an initial plan for the adult child's care within 60 days, then a yearly plan that includes a report from a physician or advanced practice registered nurse. Fla. Stat. §§ 744.363, 744.3675.
• If you manage property: file an inventory within 60 days, then a yearly accounting that the clerk audits, and keep the adult child's money separate from your own. Fla. Stat. §§ 744.365, 744.3678. A bond is generally required for a guardian of the property unless waived; a restricted depository account can replace or reduce it, though withdrawals then require court orders. Fla. Stat. §§ 744.351, 69.031.
• Get court approval before certain actions, such as moving the adult child to a non-adjacent county or out of Florida, or selling property. Fla. Stat. §§ 744.1098, 744.3215(4). A move out of Florida generally requires establishing a guardianship in the new state before the Florida guardianship closes.
• File reports on time. The court can impose penalties for late reports, including fines that may not be paid from the adult child's assets, so request more time before a deadline if needed. Fla. Stat. § 744.367.

These arrangements are also not necessarily permanent. In guardian advocacy, any interested person may file a suggestion of restoration if the adult gains the ability to make decisions in a delegated area, and a guardianship is subject to review if an alternative is later shown to meet the person's needs. Fla. Stat. §§ 393.12(12), 744.462.

Questions Families Often Consider First

• Can the adult child understand and sign a document naming someone to help?
• Which decisions can the adult child make alone, with help, or not at all?
• Does the adult child have documents already, and do doctors and banks accept them?
• What income, benefits, and assets does the adult child have, and is an inheritance or settlement expected?
• Who would serve, and who would be the backup?
• Do other family members agree, and what does the adult child want?

Frequently Asked Questions

Can I still make decisions for my child with a disability after they turn 18 in Florida?

Not automatically. Parents are natural guardians only while a child is a minor. At 18, that authority ends, and doctors, banks, schools, and agencies may no longer share information or accept a parent's decisions unless the parent has legal authority from documents the adult child signs or from a court order. Florida law requires the least restrictive option that meets the adult child's needs.

What is the difference between guardian advocacy and guardianship in Florida?

Guardian advocacy, under Fla. Stat. section 393.12, is for an adult with a qualifying developmental disability who can make some decisions but not others. There is no finding of incapacity and no examining committee; the court delegates only the specific areas where help is needed. Limited and plenary guardianship under chapter 744 require an adjudication of incapacity by clear and convincing evidence after a three-member examining committee evaluation and a hearing.

What options avoid court entirely when a child with a disability turns 18?

If the adult child understands what they are signing, four documents can provide authority without any court involvement: a supported decision-making agreement, a durable power of attorney, a health care surrogate designation, and a declaration naming a preneed guardian. The adult child keeps all of their rights under each. A representative payee arrangement through Social Security can also manage benefits without a guardianship.

Does a guardianship mean my adult child loses all rights?

No. In guardian advocacy and limited guardianship, the adult child keeps every right except those the court specifically assigns or removes. Even in a plenary guardianship, Florida law protects certain basic rights that cannot be delegated to a guardian. A court will not appoint a guardian at all if documents or other arrangements sufficiently meet the person's needs.

Do I need a guardianship to set up a special needs trust or ABLE account?

No. A parent can establish a special needs trust and open an ABLE account without a guardianship. A trust funded with the parent's own money is not counted as the adult child's asset for SSI and Medicaid. An ABLE account does not count against Medicaid, does not count against SSI until it grows above $100,000, and can pay housing costs without reducing SSI.

What are a guardian's ongoing duties in Florida?

A guardian of the person files an initial plan within 60 days and then a yearly plan including a physician's report. A guardian who manages property files an inventory within 60 days and a yearly accounting that the clerk audits, keeps the adult child's money separate, and needs court approval for certain actions such as moving the person out of Florida or selling property. Courts can impose penalties for late reports, and an extension should be requested before a deadline.
