Wisconsin: Adult Guardianship and Conservatorship Petition Requirements

Requirements one by one

Proceeding and state terminology

Wisconsin's involuntary Chapter 54 case may appoint a guardian of the person,
a guardian of the estate, or both. One person may hold both roles, or the court
may appoint separate people.

Wis. Stat. § 54.76(1)-(5) creates a different, voluntary estate conservatorship. An adult
resident applies personally, the court examines the applicant, and appointment
depends on the applicant's desire and the nominee's suitability. It is not an
incompetency adjudication.

Who may file and where

Under § 54.34(1), any person may petition for guardianship. Section
§ 54.30(1)-(2)
places the case in circuit court. A resident's petition may be filed in the
county of residence or physical presence. For a nonresident, venue may follow
the adult, Wisconsin assets, or the county where the petitioner proposes the
adult will live.

Only the adult resident may initiate the voluntary § 54.76 conservatorship, in
the circuit court for the adult's county of residence.

What the petition must contain

Section 54.34(1) requires the adult's identity and residence; the specific
alleged incapacity; property, income, benefits, and public-benefit status; any
current guardian; proposed guardian; interested parties and custodian; and the
petitioner's interest or official authority. The petition identifies health-care
and financial POA agents, specifies full or limited authority and rights sought,
and discloses related proceedings elsewhere.

The petition may combine person and estate relief. If the filer seeks limited
guardianship, the requested authority or rights to be removed or transferred
must be specific rather than left to a general request.

Proof required for appointment

Wis. Stat. § 54.10(3)(a)-(e) requires clear and convincing proof. For a person
guardian, impairment must prevent the adult from effectively receiving and
evaluating information or making or communicating decisions to the point that
essential physical-health and safety requirements cannot be met. For an estate
guardian, the same functional decision-making problem must threaten property
dissipation, self-support, or protection against financial exploitation.

The court must also find that accepted and reasonably available supports cannot
meet the need effectively and less restrictively. Unless the adult cannot
communicate decisions in any way, mere old age, eccentricity, poor judgment,
physical disability, or the existence of a supported decision-making agreement
cannot establish incompetence.

Alternatives the court must address

Section 54.10(3) makes alternatives part of the appointment gate. The express
list includes training, education, support services, health care, assistive
devices, supported decision-making, and other means the adult will accept. The
court also considers health-care and durable powers of attorney, trusts, joint
accounts, and other reliable resources.

The mandatory guardian ad litem reinforces that review. Under § 54.40(1),
(3)-(4), the GAL examines advance planning, interviews agents, and reports
whether it is adequate to avoid guardianship.

Notice, service, and hearing timing

Wis. Stat. § 54.38(1)-(2) requires personal service on the adult at least 10 days
before the hearing. The petition accompanies the notice, and the process server
must explain the complete contents and certify that explanation. Existing
guardians, interested persons, POA agents, custodians, and aid agencies receive
the same 10-day lead time by the methods the statute specifies.

Under § 54.44(1)-(5), the ordinary petition must be heard within 90 days after
filing. A petition involving admission under the identified nursing-home or
community-based-residential-facility procedure has a 60-day ceiling. The
examiner's report goes to the GAL and the adult's attorney at least 96 hours
before hearing.

Counsel and hearing rights

The court always appoints an attorney guardian ad litem, but that lawyer
advocates the adult's best interests rather than the adult's expressed position.
Separate advocate counsel is required when the adult requests counsel, someone
reports opposition to the petition, or the interests of justice require it;
§ 54.42(1)-(3), (5)-(6) directs appointed counsel to advocate the adult's
expressed wishes.

The adult, counsel, or GAL may demand a jury, but the demand is waived unless
made at least 48 hours before the hearing. They may present and cross-examine
witnesses. The adult has a right to be present and to an accessible hearing;
the petitioner must ensure attendance unless the GAL waives it under the
statutory factors. Hearings are closed unless the adult, or counsel acting with
the adult's consent, asks that the hearing be open.

Medical evidence or court evaluator

Under § 54.36(1), a physician or psychologist, or both, examines the adult and
reports on the presence and likely duration of the condition causing incapacity.
The statute sets no fixed prefiling age for that report; instead, the court
considers recency in deciding whether it describes the adult's current state and
how much weight to give it. Before examination, the adult is warned about use of
statements and the right to refuse participation absent a court order.

The GAL is also a mandatory investigation layer. The GAL interviews the adult
and proposed appointees, explains rights, checks advance planning, reports
suitability and adequacy, and may request additional evaluation. The adult may
obtain an independent medical or psychological examination, at county expense
if indigent.

Limits on the order

Section 54.10(3)(e) permits only powers needed for personal needs and property
management, exercised appropriately and as the least restrictive intervention.
Wis. Stat. § 54.25(2)(a)-(b), (d) makes the allocation explicit: the person guardian
has only specifically authorized powers, and every other right remains with the
adult unless the court separately removes or transfers it on clear and
convincing evidence.

Temporary guardianship under § 54.50(1)-(3) is a separate immediate-need route.
The order identifies the permitted acts and lasts no more than 60 days, with one
additional 60-day good-cause extension. The hearing ordinarily cannot occur
earlier than 48 hours after filing, and the petitioner provides physician or
psychologist evidence of a reasonable likelihood of incompetence.

What trips people up

The automatic GAL is not the adult's advocate counsel. The GAL represents best
interests; counsel appointed under § 54.42 represents expressed wishes. A case
can therefore have both lawyers, and opposition is one of the triggers for
advocate counsel.

Wisconsin's conservatorship label should not be used for the involuntary estate
track. Section 54.76 is voluntary, initiated by the adult, and does not itself
prove either competence or incompetence. An involuntary financial case uses a
guardian of the estate and the clear-and-convincing § 54.10 standard.

Common questions

Can the petition request only financial authority?

Yes. The petitioner may seek a guardian of the estate without seeking a guardian
of the person, but must prove the estate-specific functional and risk findings.

Does the adult automatically get a jury trial?

The right exists, but it is waived unless the adult, counsel, or GAL demands a
jury at least 48 hours before the hearing.

Can the adult refuse the medical or psychological examination?

Absent a court order, the adult has a right to refuse participation. The
examiner still reports, and the petitioner or GAL may ask the court to order an
examination.

Is every right transferred once a guardian is appointed?

No. The guardian receives only powers specifically authorized by statute, rule,
or order. Rights not separately removed or powers not transferred remain with
the adult.
