Plenary Guardianship Attorney in Florida: Process, Requirements & How to Start
Plenary guardianship gives you full legal authority to make medical, living, and financial decisions for an incapacitated adult family member, subject to court oversight and annual reporting requirements under Florida law. If a loved one can no longer manage their own affairs due to dementia, severe mental illness, addiction, or other incapacity, plenary guardianship is often the legal path families take to protect their interests and ensure proper care.

What Is Plenary Guardianship and Who Needs It?
Plenary guardianship is a court-ordered arrangement in which one person (the guardian) assumes full legal responsibility for another adult (the ward) who is unable to care for themselves or manage their affairs.
You may need plenary guardianship if your family member is experiencing:
- Advanced dementia or Alzheimer’s disease
- Severe mental illness or psychiatric disability
- Significant cognitive decline from stroke, brain injury, or illness
- Chronic addiction affecting their judgment and ability to function
- Developmental disability or intellectual impairment
- Other medical or psychiatric conditions rendering them incapacitated
Plenary guardianship differs from limited guardianship, which restricts the guardian’s authority to specific areas (such as medical decisions only, or financial matters only), and from emergency temporary guardianship, which provides immediate, short-term authority (typically up to 60 days) pending a full guardianship hearing.
The court retains oversight throughout the guardianship. You must file annual reports, seek court approval for major decisions, and act in the ward’s best interest at all times.
What Plenary Guardianship Covers
Plenary guardianship typically grants two types of authority: guardianship of the person and guardianship of the estate. Many cases involve both.
Guardian of the Person
As guardian of the person, you may:
- Make medical decisions and consent to treatment
- Choose the ward’s living arrangements (home, assisted living, facility)
- Arrange daily care, meals, and supervision
- Make educational or vocational decisions if applicable
- Determine social and recreational activities
Guardian of the Estate
As guardian of the estate, you may:
- Manage the ward’s financial accounts and assets
- Pay bills, taxes, and living expenses
- Buy, sell, or lease property (with court approval for major transactions)
- Invest or protect assets in the ward’s name
- Handle insurance and benefits
Court Approval & Annual Accounting
Major decisions—especially large financial transactions, sale of real property, or extraordinary medical care—require court approval. You must file an annual accounting with the court documenting how you’ve managed the ward’s finances and affairs. This protects the ward and creates a transparent record of your stewardship.
The Plenary Guardianship Process in Florida: Step by Step
The path to plenary guardianship in Florida involves several defined steps. Understanding the timeline and requirements helps you prepare and move forward with confidence.
Step 1: Initial Consultation
Contact Robinson & Casey to discuss your family member’s situation. We review their medical condition, financial circumstances, family dynamics, and your goals. We explain your options—plenary guardianship, limited guardianship, or alternatives—and answer your questions about cost, timeline, and what to expect.
Step 2: Petition Preparation & Filing
We prepare a formal petition to the court naming your family member as the alleged incapacitated person and yourself (or another qualified person) as the proposed guardian. The petition includes factual details about incapacity and requests the court to establish guardianship. We file the petition with the appropriate Florida circuit court.
Step 3: Medical Evaluation & Physician’s Affidavit
Florida law requires a physician’s affidavit as evidence of incapacity. We coordinate with your family member’s physician (or arrange an independent evaluation) to obtain a detailed medical report documenting their condition and inability to manage their affairs. This affidavit is a cornerstone of your petition.
Step 4: Notice to Interested Parties
The court requires notice to the alleged incapacitated person, their spouse (if any), adult children, parents, and other heirs or interested parties. We ensure proper notice is served so all parties have an opportunity to respond or object.
Step 5: Court Hearing & Examination
The judge holds a hearing. Your family member has the right to be present and to be represented by an attorney. The judge may examine your family member to assess their capacity. We present medical evidence, testimony, and documentation supporting incapacity. If there is no objection, the hearing may be brief; if someone contests the petition, the hearing may be more involved.
Step 6: Judge’s Order
If the court finds clear and convincing evidence of incapacity, the judge issues an order establishing plenary guardianship. The order names you as guardian and defines your authority.
Step 7: Oath, Bond & Assumption of Duties
You take an oath before the court. If required, you post a bond (though courts often waive this for family guardians). You then assume your duties as guardian, managing the ward’s person and/or estate according to the court’s order.
Timeline
Most plenary guardianship cases move from petition filing to court order in 60 to 90 days, depending on court schedule, case complexity, and whether anyone objects. Straightforward cases with no opposition may resolve faster; contested cases may take longer.

Legal Requirements for Plenary Guardianship in Florida
Florida law sets clear requirements to establish plenary guardianship. Understanding these helps you prepare and ensures your petition is complete.
Proof of Incapacity
You must present clear and convincing evidence that your family member is incapacitated—meaning they lack the capacity to manage their person or property or to make informed decisions about their care. Medical records, physician testimony, and clinical documentation are essential.
Petitioner Qualifications
The petitioner (the person filing) must be a Florida resident or have a significant connection to the case. Adult children, spouses, parents, and other family members commonly serve as petitioners.
Notice Requirements
You must provide notice to the alleged incapacitated person, spouse, adult children, parents, and other heirs. Notice ensures all interested parties know about the petition and can respond or object.
Right to Counsel & Court Hearing
The alleged incapacitated person has the right to be present at the hearing and to be represented by an attorney. The court conducts an examination and hears evidence before making a determination.
Guardian Qualifications
The proposed guardian must be qualified: no felony convictions (certain convictions disqualify you), no conflicts of interest, and court approval. The court considers whether the guardian is fit to act in the ward’s best interest.
Bond
The court may require a bond to protect the ward’s assets. However, courts often waive the bond requirement if the guardian is a close family member, though circumstances vary.

What Plenary Guardianship Covers
Full Legal Authority

Court Oversight
The court retains supervisory authority. Guardians must file annual accountings and reports, and the court can modify or terminate the guardianship if circumstances change.
Eligibility & Disqualifications
Not everyone can serve as guardian. Certain felony convictions and other factors may disqualify a person. We review your situation and advise on eligibility.
Petition Requirements
Florida law requires specific documentation, physician evaluations, and proper notice to the proposed ward and interested parties. We handle the filing and court process.
Plenary vs. Limited Guardianship
Plenary guardianship gives the guardian broad authority over all decisions. Limited guardianship restricts the guardian's powers to specific areas, leaving the ward with more independence in others.
