Plenary Guardianship Attorney in Florida

Plenary guardianship grants a guardian broad legal authority to make personal, medical, and financial decisions on behalf of an incapacitated person across nearly all areas of life. If a loved one has lost the capacity to make decisions due to dementia, brain injury, stroke, or severe mental illness, plenary guardianship may be the legal framework your family needs to protect them and manage their affairs.

Robinson & Casey handles plenary guardianship petitions and ongoing administration for families across South Florida and statewide. We guide you through the process, explain your options, and help you understand whether plenary or limited guardianship is appropriate for your loved one’s situation.

What Is Plenary Guardianship?

Plenary guardianship is a court-ordered arrangement in which a guardian is appointed to make all significant decisions for a person (called the “ward”) who lacks the capacity to make those decisions themselves. The guardian’s authority covers personal care, medical treatment, financial management, and legal matters—essentially all areas where decision-making is required.

This differs from limited guardianship, where the guardian’s authority is restricted to specific areas the court identifies based on the ward’s remaining abilities. Plenary guardianship is appropriate when the court finds clear and convincing evidence that the person lacks capacity across all major life domains.

Plenary guardianship in Florida is governed by Chapter 744 of the Florida Statutes, which establishes the legal requirements, procedures, and ongoing duties for guardians.


Who Needs Plenary Guardianship?

Plenary guardianship is appropriate for adults who lack decision-making capacity across all significant life areas. Common situations include:

  • Severe dementia or Alzheimer’s disease – when cognitive decline prevents all meaningful decision-making
  • Severe intellectual or developmental disabilities – when a person has never had the capacity to manage personal, medical, or financial affairs
  • Catastrophic brain injury or stroke – when injury results in loss of capacity across multiple domains
  • Advanced mental illness – when mental health conditions prevent decision-making in all major areas
  • Elderly individuals with multiple incapacities – when an older person lacks capacity and has no advance directives (power of attorney, healthcare proxy) in place
  • Persons unable to communicate or express preferences – when severe illness or injury prevents meaningful communication

The court determines whether plenary guardianship is necessary based on medical evidence of the person’s capacity. The American Bar Association Commission on Law and Aging recommends that courts consider less-restrictive alternatives before imposing full guardianship, including limited guardianship, power of attorney, and healthcare proxy arrangements.


What Plenary Guardianship Covers

A plenary guardian has authority to make decisions in the following areas on behalf of the ward:

Personal Decisions – Where the ward lives and the type of living arrangement (home, assisted living, facility) – Daily care, nutrition, hygiene, and social activities – Education or vocational training, if applicable

Medical Decisions – Choice of healthcare providers and medical facilities – Consent to medical treatment, surgery, and medication – End-of-life care decisions, including hospice and palliative care – Mental health treatment and psychiatric medication

Financial Decisions – Income management and bill payment – Asset protection and investment decisions – Real property transactions and contracts – Tax filings and benefit applications

Legal Matters – Lawsuits on behalf of the ward – Property transactions and contracts – Estate planning and probate matters

Ongoing Court Duties – Filing annual accountings showing how the ward’s money was spent – Submitting annual status reports to the court – Maintaining records of all decisions and transactions – Acting always in the ward’s best interest

The Plenary Guardianship Process: Step-by-Step

Establishing plenary guardianship in Florida involves a formal court process designed to protect the alleged incapacitated person’s rights while ensuring proper legal authority is granted.

Step 1: Petition Filing Your attorney prepares and files a guardianship petition with the court. The petition names the proposed ward, the proposed guardian, and the reason guardianship is needed. You’ll gather documents including medical records, financial information, and family background.

Step 2: Medical Evaluation The court appoints a physician to examine the proposed ward and evaluate their capacity. The physician submits a written report to the court detailing the person’s mental and physical condition and whether they lack capacity to manage their affairs.

Step 3: Notice and Service All interested parties—including the proposed ward, family members, and others identified by law—receive formal notice of the guardianship proceeding. The proposed ward has the right to know about the case and to respond.

Step 4: Hearing The court holds a hearing where evidence of incapacity is presented. The proposed ward has the right to attend, to be represented by an attorney, and to contest the guardianship. The judge considers the medical evaluation, testimony, and other evidence.

Step 5: Court Order If the court finds clear and convincing evidence of incapacity, it enters an order establishing plenary guardianship. The order specifies the guardian’s powers and any limitations the court imposes.

Step 6: Letters of Guardianship The guardian receives official court documents (letters of guardianship) that authorize them to act on the ward’s behalf. Banks, healthcare providers, and other institutions recognize these letters as proof of authority.

Step 7: Ongoing Administration The guardian manages the ward’s personal, medical, and financial affairs. Each year, the guardian files an accounting with the court showing income, expenses, and assets. The guardian also submits a status report on the ward’s condition and care.


Timeline and What to Expect

The plenary guardianship process typically unfolds as follows:

  • Initial consultation to petition filing: 1–2 weeks (depends on how quickly you gather medical records and financial documents)
  • Petition filing to hearing: typically 4–8 weeks in Florida courts
  • Hearing to court order: same day or within a few days if the case is uncontested
  • Total process: 2–3 months for straightforward cases; longer if the case is contested or if the medical evaluation is delayed
  • Ongoing: annual accountings and status reports are required each year the guardianship remains in effect

If the proposed ward contests the guardianship or if there are disputes among family members, the timeline may extend. We keep you informed at each stage and prepare you for what to expect.

Common Questions About Plenary Guardianship

Can a family member serve as guardian?

Yes. Any competent adult can serve as guardian. Family members are often appointed, though the court may also appoint a professional guardian if no suitable family member is available or willing to serve.

What if the proposed ward objects to guardianship?

The proposed ward has the right to contest the petition. The court will hold a hearing and consider the ward’s objection, their wishes, and the evidence of capacity. The ward may be represented by an attorney. The court must find clear and convincing evidence of incapacity before ordering guardianship.

How much does plenary guardianship cost?

Attorney fees vary based on the complexity of the case. Uncontested cases are typically less expensive than contested ones. Court filing fees and the cost of the medical evaluation also apply. We discuss fees and costs in your initial consultation.

What are the guardian’s responsibilities?

Guardians must act in the ward’s best interest, manage finances prudently and honestly, file annual accountings with the court, maintain records, and ensure the ward’s safety and well-being. Guardians are accountable to the court.

Can plenary guardianship be ended?

Yes. If the ward regains capacity, either the guardian or the ward may petition the court to terminate guardianship. The court will hold a hearing and, if satisfied that capacity has been restored, will end the guardianship.

What are alternatives to plenary guardianship?

Depending on the person’s capacity and needs, alternatives include limited guardianship (authority over specific areas only), power of attorney (if the person can still understand and sign the document), healthcare proxy (for medical decisions only), and mental health guardianship (for mental health treatment decisions). We review all options with you.

Yes. Any competent adult can serve as guardian. Family members are often appointed, though the court may also appoint a professional guardian if no suitable family member is available or willing to serve.

What if the proposed ward objects to guardianship?

The proposed ward has the right to contest the petition. The court will hold a hearing and consider the evidence and arguments presented by both sides before deciding whether to establish guardianship.

What is the difference between plenary and limited guardianship?

Plenary guardianship grants broad authority over all personal, medical, and financial decisions. Limited guardianship restricts the guardian's powers to specific areas, allowing the ward to retain decision-making rights in other matters.

How long does a plenary guardianship last?

A plenary guardianship continues until the ward regains capacity, the guardianship is terminated by the court, or the ward passes away. Annual reporting to the court is typically required.
