File a Plenary Guardianship Petition in Florida

File a Plenary Guardianship Petition in Florida: Process & Requirements

A plenary guardianship petition grants a guardian broad authority to manage an incapacitated person’s medical care, living arrangements, finances, and property. If you’re seeking to establish guardianship over an adult or minor who cannot make informed decisions about their own welfare, filing a plenary guardianship petition is the legal path forward in Florida.

This guide walks you through what a plenary guardianship petition is, who needs one, what the filing process entails, realistic timelines, and why working with an attorney matters for getting it right.

What Is a Plenary Guardianship Petition in Florida?

A plenary guardianship petition is a court filing that asks a judge to appoint a guardian with full authority over an incapacitated person’s affairs.

Under Florida Statutes Chapter 744, a plenary guardian can make decisions about the ward’s (the incapacitated person’s) medical treatment, where they live, how their money is spent, and how their property is managed. The guardian acts as a legal representative and is accountable to the court.

Plenary guardianship differs from limited guardianship, which restricts the guardian’s authority to specific areas—for example, financial management only, or medical decisions only—when the incapacitated person retains some capacity to handle other matters.

A plenary guardianship is court-supervised. The guardian must file annual reports with the court, account for the ward’s finances, and follow Florida law regarding the ward’s rights and protections.

Who Needs to File a Plenary Guardianship Petition?

You may need to file a plenary guardianship petition if:

• An adult family member has lost capacity due to dementia, stroke, brain injury, severe mental illness, developmental disability, or another condition that prevents them from managing their person or estate.
• A minor has significant disabilities or special needs that require ongoing guardianship beyond what parental authority provides.
• No power of attorney or healthcare proxy exists, or the person never appointed one before losing capacity.
• The incapacitated person has no spouse or parent able to act on their behalf.
• The person is unable to make informed decisions about their health, safety, housing, or finances.

Common situations include elderly parents with Alzheimer’s disease, adult children with developmental disabilities, and individuals recovering from catastrophic injury or illness.

What Does a Plenary Guardianship Petition Include?

A complete plenary guardianship petition filing contains:

• Petition form — typically Florida Supreme Court Form 12.901(b)(1) or the equivalent required by your county court.
• Physician’s affidavit or medical report — the cornerstone of your petition; it documents specific facts showing the person lacks capacity to manage their person and/or estate.
• Affidavit of incapacity — supporting documentation of the person’s inability to make informed decisions.
• Proposed guardian’s background and qualifications — information about who will serve as guardian.
• Proposed guardian’s oath and acceptance — the guardian’s sworn commitment to serve.
• Notice to interested parties — copies served on the alleged incapacitated person, spouse, adult children, parents, and other family members as required by law.
• Court filing fees and service costs — paid to the court and process server.

Your attorney prepares these documents to comply with Florida court rules and local county requirements.

The Plenary Guardianship Petition Process: Step-by-Step

Step 1: Initial Consultation and Case Assessment

You meet with your attorney to discuss the situation, review medical records, and clarify your guardianship goals. Your attorney assesses whether plenary guardianship is appropriate or whether limited guardianship or another option might fit better.

Step 2: Gather Medical Evidence

Your attorney works with the incapacitated person’s treating physician to obtain a physician’s affidavit. The affidavit must document the diagnosis, functional limitations, and specific reasons the person cannot manage their person or estate. If no treating physician is available, your attorney can arrange an independent medical evaluation.

Step 3: Prepare Petition Documents

Your attorney drafts the petition, proposed guardian oath, and supporting affidavits. All documents are tailored to your county’s local court rules and Florida statutory requirements.

Step 4: File Petition with the Court

The completed petition is filed with the circuit court in the county where the incapacitated person resides. Your attorney handles all filing and ensures proper documentation.

Step 5: Serve Notice

Copies of the petition and notice of hearing are served on the alleged incapacitated person, family members, and other interested parties as required by Florida Statutes §744.331.

Step 6: Attend Hearing (If Required)

In many uncontested cases, the court approves the petition without a hearing. If a hearing is scheduled, you and your attorney present evidence of incapacity. The court may appoint an attorney or guardian ad litem to represent the alleged incapacitated person’s interests.

Step 7: Court Order

The judge issues an order establishing plenary guardianship and naming the guardian.

Step 8: Post-Appointment

The guardian takes oath, receives letters of guardianship from the court, and begins managing the ward’s affairs. The guardian must file annual accountings and reports with the court.

Timeline: How Long Does Filing a Plenary Guardianship Petition Take?

Realistic timelines for each phase:

• Initial preparation and document gathering: 1–2 weeks
• Medical evaluation and physician’s affidavit: 1–3 weeks (depends on physician availability)
• Court filing and service of notice: 1 week
• Waiting period before hearing: 2–4 weeks (varies by county and court schedule)
• Hearing and court decision: same day or within days of hearing
• Total timeline: 6–12 weeks from initial consultation to court order

Emergency situations: If you need guardianship urgently—for example, to authorize medical treatment or prevent harm—you can file for emergency temporary guardianship, which is a faster process and can be filed alongside a plenary petition.

What Are the Requirements to File a Plenary Guardianship Petition?

To file a plenary guardianship petition, you must meet these requirements:

• Incapacity: Medical evidence must show the person lacks capacity to manage their person and/or estate.
• Residency: The incapacitated person must reside in Florida or have property in Florida.
• Proposed guardian: Must be at least 18 years old, of sound mind, and willing to serve.
• No disqualifying factors: The guardian cannot have felony convictions, active substance abuse issues, or conflicts of interest that would prevent them from acting in the ward’s best interest.
• Notice: All interested parties must be notified of the petition and hearing.
• Court jurisdiction: The petition is filed in the circuit court of the county where the incapacitated person resides.

Medical Evidence and the Physician’s Affidavit

The physician’s affidavit is the foundation of your plenary guardianship petition.

The affidavit must document specific facts showing the person lacks capacity to manage their person and/or estate. The physician should detail the diagnosis, functional limitations, and inability to make informed decisions. Under Florida law, the affidavit must be signed and notarized. The physician may be required to testify at the hearing if the petition is contested.

Robinson & Casey works directly with your physician to ensure the affidavit meets Florida court requirements and clearly establishes incapacity. If no treating physician is available, we can help arrange an independent medical evaluation so your petition has the medical foundation it needs.
