Plenary Guardianship Petition in Florida: What It Is, How It Works & How We Help
A plenary guardianship petition is a formal request to a Florida court to grant one person (the guardian) broad legal authority to make all major decisions for another person (the ward) who cannot make them. The guardian gains power over medical care, finances, living arrangements, and legal matters—everything the ward can no longer handle independently.
This is different from limited guardianship, which restricts authority to specific areas. Plenary guardianship is the most comprehensive form of legal guardianship, used when incapacity affects all areas of decision-making.
If you're caring for an incapacitated loved one and need full legal authority to make medical, financial, and personal decisions, a plenary guardianship petition is the path forward—and families in your situation can reach out to us. Talk it through with our team — the first consultation is free, confidential, and carries no obligation.

What Is a Plenary Guardianship Petition?
A plenary guardianship petition is a court filing that seeks to establish full legal guardianship over an incapacitated adult or minor. The petition asks the judge to declare the person incapacitated and to appoint a guardian with sweeping decision-making power.
Scope of authority. Once approved, the guardian can make decisions about:
- Where the ward lives and what daily care they receive
- Medical treatment, surgery, medication, and psychiatric care
- Bank accounts, investments, real estate, and bills
- Legal documents, contracts, and claims on behalf of the ward
- Educational choices (for minors)
- Social and recreational activities, within the ward’s best interests
When it’s used. Families file plenary guardianship petitions when an adult or minor can no longer manage their own affairs due to dementia, severe mental illness, traumatic brain injury, advanced illness, or other incapacity. Unlike limited guardianship—which preserves some rights and autonomy—plenary guardianship transfers nearly all decision-making authority to the guardian.
Court involvement is mandatory. The petition doesn’t take effect until a judge approves it after reviewing evidence and hearing testimony. The ward has the right to attend, object, and be represented by an attorney.
Who Needs a Plenary Guardianship Petition
Plenary guardianship petitions are filed for:
- Incapacitated adults with dementia, Alzheimer’s disease, severe mental illness, traumatic brain injury, stroke, or end-stage illness who can no longer make any significant decisions
- Minors without capable parents when both parents are deceased, incapacitated, or unfit to care for the child
- Situations requiring comprehensive authority where the person needs a guardian to handle medical emergencies, manage substantial assets, arrange living care, and represent them legally all at once
- Family members and caregivers already providing hands-on care but lacking the legal right to sign medical forms, access bank accounts, or make binding decisions
If you’re already acting as a caregiver but hitting walls—hospitals won’t discuss treatment without legal authority, or you can’t access the person’s accounts—a plenary guardianship petition removes those barriers.
What a Plenary Guardianship Petition Covers
The scope of authority granted by a plenary guardianship petition is broad. Here’s what a guardian can do:
Personal and medical decisions: – Decide where the ward lives (home, assisted living, nursing facility) – Consent to surgery, hospitalization, medication, and psychiatric treatment – Choose healthcare providers and make end-of-life care decisions – Arrange daily care, meals, transportation, and hygiene support
Financial and property management: – Access and manage bank accounts and investments – Pay bills, file taxes, and handle debt – Buy, sell, or lease real estate – Manage insurance, retirement accounts, and estate matters
Legal authority: – Sign documents on the ward’s behalf – Enter contracts necessary for the ward’s care or benefit – Pursue legal claims or settle disputes – Represent the ward in court proceedings
Educational choices (for minors): – Enroll the minor in school – Make special education decisions – Authorize medical or psychological evaluations
Social and recreational decisions: – Subject to the ward’s best interests and court oversight
All of these powers are exercised under court supervision. The guardian must act in the ward’s best interest, not their own, and must report to the court annually.
The Plenary Guardianship Petition Process: Step-by-Step
Filing a plenary guardianship petition in Florida follows a structured legal process. Here’s what happens:
Step 1 – Initial consultation. You meet with an attorney to discuss the ward’s circumstances, capacity, medical history, family situation, and your goals. The attorney determines whether plenary guardianship is appropriate or if limited guardianship or another option might serve you better.
Step 2 – Gather documentation. You collect medical records, psychiatric evaluations, financial statements, the ward’s identification, and family background information. These documents support the petition and prove incapacity.
Step 3 – Physician evaluation. Florida law requires a physician’s affidavit confirming the ward’s incapacity. The attorney coordinates with a doctor who has examined or treated the ward (or arranges an independent evaluation) to obtain this mandatory affidavit. Under Fla. Stat. § 744.331, the affidavit must state the physician’s opinion on the ward’s ability to manage property and personal affairs.
Step 4 – Petition preparation. The attorney drafts the formal petition with all required allegations, information about the ward, proposed guardian details, and supporting documentation. The petition must comply with Florida probate court rules and local court requirements.
Step 5 – File with the court. The petition is filed in the probate division of the circuit court in the county where the ward lives. Filing fees apply and vary by county. Other costs may also apply.
Step 6 – Serve notice. The ward, family members, and other interested parties must be notified of the petition. Your attorney can explain the notice requirements that apply to your case.
Step 7 – Adjudication hearing. The court schedules a hearing where the judge reviews evidence, hears testimony from you and the physician, and may speak with the ward. The ward has the right to be represented by an attorney and to object. The judge considers the ward’s wishes, the evidence of incapacity, and whether plenary guardianship is in the ward’s best interest.
Step 8 – Court order and appointment. If the judge approves, the court issues an order establishing plenary guardianship and appointing the guardian.
Step 9 – Guardian oath and accounting. The guardian takes an oath of office and receives letters of guardianship (official proof of authority). Depending on the ward’s assets, the guardian may be required to file annual accountings with the court showing how the ward’s money was spent.
Timeline & What to Expect
Initial consultation to petition filing: 1–3 weeks, depending on how quickly you gather documents and schedule the physician evaluation.
Court processing after filing: 2–6 weeks before the hearing date is set.
Contested cases: If the ward or an interested party objects, the process may extend 6 months or longer.
Ongoing obligations: After appointment, the guardian files annual accountings (or more frequently if the court orders it) and must comply with all court reporting requirements for as long as the guardianship is active.

Common Questions About Plenary Guardianship Petitions

Costs vary based on case complexity, but typically include attorney fees, court filing fees, physician evaluation fees, and publication costs. We discuss fees transparently during your consultation.
Q: Will my loved one have a say in the guardianship hearing?
Yes. The ward has the right to attend the hearing, be represented by an attorney, and present evidence. The court considers the ward’s wishes and best interests.
Q: What happens after the guardianship is approved?
The guardian takes an oath, receives letters of guardianship, and assumes legal authority. Guardians must file annual accountings and report to the court regularly.
Q: Can a plenary guardianship be challenged or modified?
Yes. Interested parties can petition the court to modify or terminate guardianship if circumstances change or the guardian fails to act appropriately.

Plenary vs. Limited Guardianship
Plenary guardianship grants broad authority over all personal, medical, and financial decisions. Limited guardianship restricts the guardian's powers to specific areas—for example, medical decisions only—while the ward retains rights in other areas. Understanding which form fits your situation is essential.

While self-representation is possible, plenary guardianship petitions involve complex legal and medical requirements. Working with an attorney can help with documentation and with the Florida law requirements that apply to the petition.
What does a plenary guardian's authority cover?
A plenary guardian has authority over the ward's personal care, medical decisions, and financial and property matters. This broad scope requires careful adherence to court orders and fiduciary duties.

Timeline varies based on court schedules, the complexity of the case, and whether the petition is contested. Robinson & Casey will guide you through each stage and keep you informed.
