Ohio: Adult Guardianship and Conservatorship Petition Requirements

Requirements one by one

Proceeding and state terminology

Ohio's ordinary involuntary adult case is guardianship under Chapter 2111. The
probate court may appoint a guardian of the person, estate, or both, and may
limit the powers and duration under § 2111.02.

Ohio uses conservatorship for a different, voluntary arrangement. Under
§ 2111.021, a competent but physically infirm adult petitions in the county of
residence and identifies the person, property, powers, limits, duration, and
proposed conservator. Filing or establishing that conservatorship is not
evidence of mental impairment.

Who may file and where

Section 2111.02(A) permits any interested party to apply and lets the probate
court act on its own motion. The nonexclusive interested-party examples include
a person nominated in a durable power of attorney or guardian-nomination
writing. For an adult guardianship, the respondent must reside or have legal
settlement in the county, subject to the interstate-jurisdiction rules the
section incorporates.

What the petition must contain

Section 2111.03 requires the estate's probable value and real-property rents,
the applicant's specified criminal charge or conviction history, whether a
limited guardianship is requested and its powers and duration, and the adult's
name, age, residence, supporting facts, and next of kin.

Supreme Court Standard Probate Form 17.0 adds the practical statewide filing
shape: guardian of person, estate, or both; limited or non-limited; necessity;
personal and real property, rents, and other annual income; applicant
relationship; any guardian nomination; attached next-of-kin list; and attached
Statement of Expert Evaluation. Local probate courts may require additional
forms.

Proof required for appointment

Section 2111.02(C)(3) assigns clear and convincing evidence to the finding of
incompetency. Under § 2111.01(D), the question is whether mental impairment caused by the
listed illness, disability, intellectual-disability, or chronic-substance-abuse
categories leaves the adult incapable of proper self or property care or of
providing for people the adult is legally required to support.

That finding does not end the analysis. Section 2111.02(A) authorizes
appointment only "[i]f found necessary," and subsection (C) separately makes
less restrictive alternatives part of the hearing. The statute does not assign
the necessity finding a separate burden of proof.

Alternatives the court must address

Under § 2111.02(C)(5), evidence of a less restrictive alternative may be
introduced and must be considered when it is. Subsection (C)(6) permits denial
of guardianship when an alternative exists. The probate investigator must also
recommend either guardianship or a less restrictive alternative under
§ 2111.041.

A limited guardian is one statutory alternative to broader authority. The
order and letters must state the reasons and specific powers, and the adult
retains every right outside those powers. Pending SB 35 would create a formal
supported-decision-making plan for adults with developmental disabilities and
expressly make its use admissible as a less restrictive alternative.

Notice, service, and hearing timing

Except for interim and emergency appointments, § 2111.04 requires at least
seven days between court-caused written notice and appointment. The adult must
receive personal service, ordinarily through a probate investigator, and the
boldface notice must explain the hearing, the right to attend and contest, the
right to counsel, and the other § 2111.02(C)(7) rights. Known Ohio-resident next
of kin also receive notice.

The adult cannot waive notice. After service, the court may shorten the
seven-day period only for good cause.

Counsel and hearing rights

The adult may attend and contest and has a right to independent counsel of the
adult's choice, a chosen friend or family member at the hearing, and evidence
from an independent expert. If indigent, the adult receives counsel and an
independent evaluator at court expense on request, along with appointed
counsel and necessary transcripts for an appeal.

The investigator reports whether counsel should be appointed, and § 2111.031
also permits the court to appoint a qualified person to represent the adult.
The appointment provisions list no jury-trial right.

Medical evidence or court evaluator

Form 17.0 attaches Standard Probate Form 17.1. For a new application, Form 17.1
says the evaluation must be completed before filing by a licensed physician or
licensed clinical psychologist. The current form records the evaluation date
and history, diagnosis and functional observations, medication effects,
personal-care and medical-decision ability, financial-management ability,
recommended living situation, prognosis, and an opinion whether guardianship
should be established or denied. The form expressly says it is evidence, not a
declaration of competency or incompetency.

The court may appoint physicians, advanced-practice nurses, or other qualified
people to examine, investigate, or represent the adult under § 2111.031. At
service, § 2111.041 separately requires a probate investigator to investigate,
communicate the rights in an understandable way, describe observed condition,
and recommend guardianship or an alternative and whether counsel is needed.
The court must consider that report before establishing guardianship.

Limits on the order

A limited guardian's order and letters must explain the reasons and specify the
powers. The adult retains all rights in areas the order does not affect. The
court may deny any guardianship if a less restrictive alternative exists.

Emergency guardianship under § 2111.02(B)(3) is separate. It requires reasonable
certainty that immediate action is needed to prevent significant injury,
limits powers to those necessary to prevent that injury, and lasts no more than
72 hours. After notice and hearing, the court may extend it for good cause by no
more than 30 additional days.

What trips people up

The expert evaluation does not decide the case. Form 17.1 expressly says it
is evidence. The probate court still applies the statutory clear-and-convincing
standard and decides necessity and alternatives.

Appointed counsel is request-triggered for an indigent adult. The statute
protects chosen independent counsel for everyone, but court-expense counsel and
an independent evaluator arise when an indigent respondent requests them.

Ohio conservatorship is not a softer finding of incompetency. It is a
voluntary petition by a competent, physically infirm adult who defines the
powers and may terminate the arrangement in writing.

Common questions

Can the adult oppose the application? Yes. The personal notice must explain
the right to contest, and § 2111.02 protects counsel and independent-expert
evidence.

Can a friend attend the hearing? Yes. The adult has the right to have a
chosen friend or family member present.

Does the adult keep rights under a limited guardianship? Yes. Every area not
affected by the limited order remains with the adult.
