Wisconsin Guardianship: Petition, Hearing, and Duties

Wisconsin guardianship is a court-supervised arrangement in which a judge appoints someone to make personal, medical, or financial decisions for an adult or minor who cannot make those decisions safely on their own. For an adult, the judge must be convinced by clear and convincing evidence that the person’s impairment leaves them unable to evaluate information or communicate decisions well enough to meet their own needs.¹ Because the order can strip away significant civil rights, Wisconsin treats guardianship as a last resort and requires the court to look first at whether a less restrictive arrangement would work.

When Guardianship Is Appropriate

Chapter 54 of the Wisconsin Statutes governs guardianship for both adults and minors.² For an adult, the petitioner has to show a qualifying condition — such as a developmental disability, a degenerative brain disorder, or a serious and persistent mental illness — that produces a functional impairment severe enough that the person cannot meet their own needs for physical health or safety.³ The clear-and-convincing standard sits above the usual “more likely than not” test used in most civil cases.¹

For minors, guardianship typically comes up when a parent has died, is unavailable, or cannot provide care. Children in child-protection proceedings generally move through Chapter 48, while other minor guardianships are handled under Chapter 54.⁴

Guardian of the Person vs. Guardian of the Estate

Wisconsin courts can grant authority over the individual, over their finances, or over both. The duties, powers, and reporting obligations differ in each.

A guardian of the person makes decisions about medical care, housing, education, employment, travel, and daily needs. The guardian can consent to medical treatment if the ward does not protest and can consent to involuntary medical treatment, with one key exception: psychotropic medication can only be administered involuntarily under a separate court order.⁵

A guardian of the estate handles the ward’s income, investments, debts, and property. If the court requires a bond, the guardian must post it before receiving letters of guardianship.⁶

One person can serve in both roles, or the court can split them between two people. Every guardian must place the least possible restriction on the ward’s personal liberty and promote the greatest possible integration into the community.⁵

Who the Court Will Appoint

Anyone can file the petition, but the judge follows a statutory priority order when deciding who actually gets the job. The court considers the proposed ward’s own preferences and the views of family members, though the ward’s best interests ultimately control when those preferences conflict.⁷

In rough order of preference:

An agent already serving under a durable power of attorney. If the proposed ward previously named a financial power of attorney agent, the court must appoint that person as guardian of the estate unless it would harm the ward’s interests. The same rule applies to a health care power of attorney agent for guardianship of the person.⁷
A person the proposed ward nominated in writing, following the same formalities as a will. A minor age 14 or older can also nominate their own guardian in writing before the court.
A suitable and willing parent, for a minor or for an adult with a developmental disability or serious persistent mental illness.
A guardian named in a deceased parent’s will.

The court also screens for conflicts of interest. If a prospective guardian’s employment or relationships create a potential conflict, the judge can pass over that person regardless of priority.⁷

How to File a Guardianship Petition

The process begins with Form GN-3100, the Petition for Temporary and/or Permanent Guardianship Due to Incompetency, available through the Wisconsin Court System.⁸ The petition must describe the proposed ward’s condition, living situation, and financial standing, including bank accounts, real estate, and income sources such as Social Security or pensions. You also list the “interested persons” — typically the ward’s spouse, adult children, parents, and close heirs — so the court can give them notice.

Filed with the petition is Form GN-3130, the Examining Physician’s or Psychologist’s Report.⁹ A licensed physician or psychologist examines the proposed ward and documents the nature and extent of the impairment. The report must reach the court, the guardian ad litem, and the ward’s attorney at least 96 hours before the hearing.¹⁰

Where to File and What It Costs

File with the Register in Probate in the county where the proposed ward lives. For a guardianship of the estate where the ward’s property is worth $50,000 or less, the filing fee is $20. Above $50,000, the fee is 0.2 percent of the property’s value after subtracting debts and liens.¹¹ Guardianship-of-the-person petitions may carry separate fees; check with your county’s Register in Probate for current amounts. Attorney fees, guardian ad litem costs, and evaluation expenses are additional, and a contested case can run into several thousand dollars.

Serving the Proposed Ward

Wisconsin requires personal service on the proposed ward. A sheriff or process server must hand-deliver the petition and notice of hearing at least 10 days before the court date, explain the full contents to the proposed ward, certify that they did so, and return the certificate to the court.¹² If the proposed ward is in a nursing home or other facility, service can go through the custodian, who then personally serves the individual.

What Happens at the Hearing

Before the hearing, the court appoints a guardian ad litem, an attorney who independently investigates the situation and advocates for the proposed ward’s best interests.¹³ The guardian ad litem interviews the proposed ward, explains the petition and the hearing process, advises them of their rights in writing and orally, reviews any existing powers of attorney or advance directives, and reports to the court on whether those documents already provide enough protection to make guardianship unnecessary.

The proposed ward has several protections at the hearing:

The right to be present. If a disability or facility residence makes travel to the courthouse impossible, the court must hold the hearing wherever the ward can attend, if requested.¹
The right to a lawyer. If the proposed ward asks for counsel, opposes the petition, or the judge decides justice requires it, the court must ensure the individual has an attorney. If they cannot afford one, the county pays.¹⁴
The right to a jury trial. The proposed ward, their attorney, or the guardian ad litem can demand one, but the demand must come at least 48 hours before the hearing.¹⁵
The right to an independent medical or psychological evaluation, at county expense if the ward is indigent.

If the court finds the individual incompetent by clear and convincing evidence, it issues letters of guardianship. That court-sealed document is what the guardian shows to banks, hospitals, and other institutions to prove their authority.⁶

Temporary Guardianship for Urgent Situations

When someone faces an immediate safety risk and cannot wait for the full process, the court can appoint a temporary guardian. The petitioner must show that the particular situation requires an immediate appointment.¹⁶

A temporary guardianship lasts up to 60 days and can be extended once for another 60 days if the extension request is filed before the first period ends. After the temporary order and any extension expire, the court cannot impose another temporary guardianship on the same individual for at least 90 days.¹⁶ The temporary guardian’s authority is limited to what the court order spells out, and they cannot sell real estate or spend more than $2,000 without specific court approval.

A hearing can happen as quickly as 48 hours after filing. The petitioner must present a physician’s or psychologist’s report showing a reasonable likelihood of incompetency. The court also appoints a guardian ad litem, who must meet with the proposed ward within seven days of the hearing if that meeting could not happen beforehand.¹⁶

Which Rights the Ward Keeps and Which They Lose

A guardianship order does not automatically erase every civil right. The judge must specifically identify, right by right, which capacities the ward lacks. The court can declare incapacity in each of these areas only after making a specific finding:¹⁷

Voting, only if the ward is incapable of understanding the purpose of the election process.
Marriage, only if the court specifically removes the right to consent to marriage.
Making a will, only if specifically removed.
Jury service, only if specifically removed.
Driver’s license or professional licenses, only if the ward cannot understand the nature and risks of the licensed activity.
Sterilization or organ donation, only if specifically removed after the court finds the ward cannot understand the nature, risks, and benefits.

Some rights can never be taken away through a guardianship order. The ward retains the right to free speech, freedom of association, and the free exercise of religion, along with any other rights reserved by statute or by the state and federal constitutions.¹⁸ The court tailors the order to the individual’s limitations rather than wiping out everything at once.

Ongoing Duties After Appointment

Appointment is the start of the work, not the end. A guardian of the person files Form GN-3480, the Annual Report on the Condition of the Ward, each year.¹⁹ The report updates the court on the ward’s health, living situation, and whether the ward is in the least restrictive environment consistent with their needs.

A guardian of the estate has a heavier paper trail. Within 60 days of appointment, the guardian must file an initial inventory cataloging every asset, debt, and income source.²⁰ After that, annual accounts are due each April 15, with sworn detail on income received, investments made, and money spent on the ward’s behalf. The court can shift the annual reporting period to the anniversary of the appointment instead.²¹ Guardians who miss filings, mismanage funds, isolate the ward, or neglect the ward’s needs can be removed by the court on petition.²²

Changing or Ending a Guardianship

Guardianship is not necessarily permanent. If the ward’s condition improves, they or someone acting on their behalf can petition the court to restore specific rights or terminate the guardianship entirely.²³ A review petition can generally be filed 180 days after the most recent hearing, or at any time if the court finds exigent circumstances such as new evidence of harm.

At the hearing, the ward has the right to counsel at county expense if indigent and can demand a jury trial. The court may restore some rights while keeping others in place, or end the guardianship outright. If the court finds the ward is no longer incompetent, the guardianship of the person automatically ends.²³

Less Restrictive Alternatives to Consider First

Before filing, it is worth asking whether a less restrictive option can meet the person’s needs. Wisconsin courts are required to consider alternatives, and the guardian ad litem’s job specifically includes reporting on whether existing planning documents already provide adequate protection.¹³ Common alternatives include:

A power of attorney for health care, which lets a competent person name an agent to make medical decisions later. Wisconsin gives these agents priority if guardianship ever becomes necessary.
A durable power of attorney for finances, which lets a named agent manage money, pay bills, and handle property without court involvement unless someone challenges the agent’s actions.
Supported decision-making agreements, in which family and friends help the individual understand complex decisions without stripping legal authority. The agreement must be signed by two adult witnesses or a notary.
A Social Security representative payee, who can manage benefit payments for someone unable to handle their own finances without the cost of a full guardianship.
A special needs trust, in which a trustee manages funds for a person with a disability, often while preserving eligibility for public benefits such as Medicaid.

Powers of attorney and supported decision-making agreements only work when they are set up while the person still has capacity. Once someone has already lost that capacity and has no planning documents in place, a court guardianship may be the only remaining option.
