How to Get Guardianship of an Adult in Wisconsin

To get guardianship of an adult in Wisconsin, you file a petition in the circuit court for the county where the person lives, submit a physician’s or psychologist’s report on their capacity, serve notice on the proposed ward and other interested parties, and prove at a hearing by clear and convincing evidence that the person cannot receive and evaluate information or communicate decisions well enough to keep themselves safe or manage their finances. The court appoints a guardian ad litem to investigate, holds the hearing within 60 or 90 days of filing depending on the ward’s living situation, and issues Letters of Guardianship if it grants the petition.

Decide Whether Guardianship Is the Right Tool

Wisconsin Chapter 54 sets a specific standard. For a guardian of the person, the adult’s impairment must leave them unable to meet the basic requirements of their own physical health and safety. For a guardian of the estate, it must leave them unable to manage property or finances to the point that assets face dissipation, they cannot support themselves, or they cannot prevent financial exploitation.¹ The statute is not tied to any particular diagnosis. What matters is functional impact.

Before filing, check whether the adult already signed a power of attorney for health care or a durable financial power of attorney. Those documents survive a later incompetency finding, and the court can revoke or limit them only for good cause. If existing advance planning already covers the person’s needs adequately, the court must dismiss a guardianship petition entirely.² A guardianship you did not need can cost weeks of time and hundreds of dollars in fees.

Choose the Type and Scope You Will Ask For

Wisconsin recognizes two guardian roles that can be sought together or separately. A guardian of the person handles healthcare, housing, and social services decisions, and must visit the ward regularly and consult with care providers.³ A guardian of the estate takes possession of the ward’s property, pays debts, files tax returns, manages investments, and accounts for every dollar.⁴

You also have to decide between full and limited guardianship. The petition itself must state which you are requesting and, if limited, which specific powers the guardian would receive or which rights of the individual the petitioner wants transferred.⁵ Courts are required to grant only the authority the situation actually demands. Every right the order does not transfer stays with the ward.³ Ask for what you can prove is needed, and no more.

Confirm You Can Serve as Guardian

The court weighs the proposed ward’s own preferences and family opinions in choosing a guardian. Priority goes to people the ward previously nominated in a power of attorney or similar document, followed by parents and other family. If no suitable individual is available, the court may appoint a private nonprofit corporation organized under Wisconsin law that the Department of Health Services has approved as a suitable guardian.⁶

You will need to disclose your background. Before the hearing, the proposed guardian must file a sworn, notarized statement covering any criminal charges or convictions, any bankruptcy filings, and the status of any professional licenses. The court also considers potential conflicts of interest from your employment or other relationships.⁶ A criminal record does not automatically disqualify you, but the judge weighs the nature of the offense.

Prepare the Documents

Standardized forms are available through the Wisconsin Court System website and your local Register in Probate office.

Petition for Guardianship (Form GN-3100)

The petition collects the proposed ward’s name, date of birth, residence, and a description of the specific incapacity. It also requires the approximate value of the ward’s property, the names and addresses of all interested parties, information about any existing advance directives, and whether you are seeking full or limited guardianship.⁵ You must also identify any public benefits the proposed ward receives and disclose whether guardianship proceedings are pending in another state.⁷

Statement of Acts by Proposed Guardian (Form GN-3140)

This is the background disclosure form. It must be filed with the court at least 96 hours before the hearing.⁶

Physician or Psychologist Report

A licensed physician or psychologist must examine the proposed ward and produce a written report stating a professional opinion about the presence and likely duration of any condition causing incapacity. Before the exam, the examiner must warn the proposed ward that their statements may be used as a basis for a finding of incompetency and that they have a right to refuse to participate.⁸ Copies go to the proposed ward or their attorney, the guardian ad litem, and the petitioner’s attorney. This report is the single most important piece of evidence at the hearing, so its quality matters.

File the Petition and Pay the Fee

File the petition package with the Register in Probate in the county where the proposed ward lives. For a guardianship of the estate, the filing fee is $20 if the estate is worth $50,000 or less, or 0.2% of the property’s value minus debts if it exceeds that threshold.⁹ Guardianship of the person alone carries a separate, generally modest filing fee. You can petition the court for a waiver if you cannot afford the fee.

Once the petition is filed, the court appoints a guardian ad litem. This is an attorney whose job is to represent the proposed ward’s best interests. The guardian ad litem interviews the proposed ward, explains their rights, investigates the situation, and gives the judge a recommendation on whether guardianship is warranted and what form it should take. Their fees are typically paid from the ward’s assets if the court finds them reasonable.

Serve Notice on the Right People

The proposed ward must receive personal service of the petition at least 10 days before the hearing. The same 10-day notice goes by personal service or certified mail to any existing guardian, and by regular mail or personal service to the ward’s attorney, presumptive heirs, the agent under any existing power of attorney, and anyone else the court designates.¹⁰ Missing a required recipient can delay the hearing.

Attend the Hearing

A standard guardianship petition must be heard within 90 days of filing. If the proposed ward has been admitted to a nursing home or community-based residential facility, the timeline tightens to 60 days.¹¹ The proposed ward must attend unless the guardian ad litem waives attendance. You, as the proposed guardian, must appear in person, and any proposed standby guardian must appear as well.

The court must find incompetency by clear and convincing evidence. That is more demanding than a simple preponderance but less than the beyond-a-reasonable-doubt standard used in criminal cases.¹¹ If the evidence falls short, or if existing advance planning already addresses the person’s needs, the court dismisses the petition.²

When the court grants the petition, it issues an order specifying the guardian’s powers and any actions that will require further court approval. It then issues Letters of Guardianship. That document is what you show banks, hospitals, government agencies, and other institutions to prove your authority to act.

What You Take On After Appointment

The appointment is the start, not the finish. Guardians who treat it as a one-time event get in trouble.

A guardian of the person must file an annual report with the court and the county department covering the ward’s location, health, and whether the ward is living in the least restrictive environment consistent with their needs. Beyond paperwork, the guardian must visit the ward regularly in person, review health care records, attend care-planning meetings at any facility where the ward lives, and consult with providers before making treatment decisions.³

A guardian of the estate must prepare an inventory of all the ward’s property, take possession of it, and then manage it with the care a prudent person would use with their own finances. Annual financial accountings are required, and the guardian files tax returns and pays debts from the ward’s income and assets. If the ward receives government benefits that require a representative payee and no one else holds that role, the estate guardian must apply for it.⁴ Late or inaccurate accountings can be grounds for removal.

Two federal steps often get missed. First, file IRS Form 56 to notify the government of the fiduciary relationship; this tells the IRS you are now responsible for filing returns and paying taxes on the ward’s behalf.¹² Second, a court appointment does not automatically make you the representative payee for the ward’s Social Security or SSI benefits. The Social Security Administration runs its own process; start it at your local Social Security office or by calling 800-772-1213.¹³

The Guardianship Is Not Necessarily Permanent

A Wisconsin guardianship continues for the ward’s lifetime unless the court terminates it, but it can be reviewed. The ward, anyone acting on the ward’s behalf, or the guardian can petition for a review of incompetency, a change of guardian, or a restoration of specific rights. The petition can be filed any time after 180 days from the last hearing, or sooner if the court finds urgent circumstances such as new medical evidence. The court appoints a new guardian ad litem, sets a hearing, and gives the ward the right to a jury trial and to counsel, with the county paying if the ward is indigent.¹⁴ If the ward’s condition improves, revisit the order. The framework is built on the principle that a guardianship should be no broader than necessary.
