Adult Guardianship in Ohio

Reviewed by DocDraft Legal Team - Ohio - Last updated October 9, 2026

In Ohio the probate court of the county where the person resides or has a legal settlement appoints a guardian of the person, the estate, or both for an adult the statute calls an "incompetent" (R.C. 2111.02(A)). The application goes on Standard Probate Form 17.0 and is accompanied by a physician's or clinical psychologist's statement, such as the Statement of Expert Evaluation (Form 17.1) completed before filing, or by a statement that the person refused to be examined (Sup.R. 8.31(A)). The burden of proving incompetency is clear and convincing evidence (R.C. 2111.02(C)(3)). A probate court investigator personally serves notice and reports to the court, and no guardian may be appointed until at least seven days after notice of the hearing is served, unless the court finds good cause after service; the wait does not apply to interim or emergency guardians. In Ohio a "conservatorship" under R.C. 2111.021 is a separate voluntary arrangement, not the court process for an adult who cannot decide for themselves.

How does a court decide an adult needs a guardian in Ohio?

The probate court must find the person is an "incompetent" under R.C. 2111.01(D)(1): so mentally impaired, from a mental or physical illness or disability, intellectual disability, or chronic substance abuse, that the person is incapable of taking proper care of self or property or fails to provide for those the person must support. The burden of proof is clear and convincing evidence.

Which court and which form start an adult guardianship in Ohio?

The application is filed in the probate court of the county where the person resides or has a legal settlement. The Supreme Court of Ohio's Standard Probate Form 17.0, Application for Appointment of Guardian (an Alleged Incompetent), is the statewide form. Ask the probate clerk about local requirements, because the court's own rules control what it accepts.

Does Ohio require a doctor's report for an adult guardianship?

Under Sup.R. 8.31(A), an application on the ground of mental incompetency must be accompanied by a statement of a physician or clinical psychologist, or by a statement that the prospective ward refused to be examined. Form 17.1 says the evaluation must be completed before the application is filed. It is evidence for the court, not a ruling on competence.

What rights does the person have in an Ohio guardianship case?

An investigator personally serves notice stating the rights to attend, contest and have an attorney, generally at least seven days before appointment; after service the court may act sooner for good cause, and interim or emergency guardians are exempt. Notice cannot be waived. The person may choose counsel; if indigent, on request, counsel and an independent expert are court-paid.

Ohio's incompetent standard, Form 17.1 evaluation, and seven-day notice

Ohio uses its own vocabulary. The adult is the "incompetent" (also called the ward or alleged incompetent), and the probate court appoints a guardian of the person, the estate, or both under R.C. Chapter 2111. A limited guardian with specific limited powers is also available, and the ward keeps all rights in areas the order does not affect (R.C. 2111.02(B)(1)). The statute defines an incompetent as a person so mentally impaired, as a result of a mental or physical illness or disability, intellectual disability, or chronic substance abuse, that the person is incapable of taking proper care of self or property or fails to provide for the family or others the person is charged by law to provide for, and the burden of proving incompetency is clear and convincing evidence (R.C. 2111.01(D)(1); R.C. 2111.02(C)(3)). Under Sup.R. 8.31(A), an application on the ground of mental incompetency must be accompanied by a statement of a physician or clinical psychologist or a statement that the prospective ward refused to be examined, and Form 17.1 says the evaluation must be completed before the application is filed. A probate court investigator serves notice on the person, communicates the person's rights in an understandable way, and files a report with a recommendation on the necessity of guardianship or a less restrictive alternative (R.C. 2111.041). No guardian of an incompetent may be appointed until at least seven days after the court has caused written notice of the hearing to be served, although after service the court may appoint earlier for good cause, and that wait does not apply to interim or emergency guardians. The person has the right to independent counsel of their choice and, if indigent and on request, to counsel and an independent expert evaluator at court expense (R.C. 2111.02(C)(7)). Ohio's "conservatorship" in R.C. 2111.021 is different: a competent, physically infirm adult may petition to place their own person or property under a conservatorship. Guardian reports are due two years after letters issue and biennially after that.

Petition form

Standard Probate Form 17.0, Application for Appointment of Guardian (an Alleged Incompetent), with Form 15.0 for next of kin. Check with the probate clerk, because the court's requirements control.

Incapacity standard and proof

"Incompetent" means a person so mentally impaired, as a result of a mental or physical illness or disability, intellectual disability, or chronic substance abuse, that the person is incapable of taking proper care of self or property or fails to provide for the family or others the person is charged by law to provide for (R.C. 2111.01(D)(1)). Burden: clear and convincing evidence (R.C. 2111.02(C)(3)).

Medical or evaluator report

Application must be accompanied by a statement of a physician or clinical psychologist, or a statement that the prospective ward refused to be examined (Sup.R. 8.31(A)). Form 17.1 must be completed before the application is filed. A probate court investigator also reports (R.C. 2111.041).

Notice and service

Written notice of the hearing, personal service on the alleged incompetent by a probate court investigator, and notice to next of kin known to reside in Ohio. No appointment until at least seven days after notice is served; the person cannot waive notice. After service the court may appoint earlier for good cause, and the wait does not apply to interim or emergency guardians (R.C. 2111.04).

Right to counsel

Independent counsel of the person's choice. If indigent, upon request, counsel and an independent expert evaluator at court expense (R.C. 2111.02(C)(7)). The court may also appoint an attorney under R.C. 2111.031.

Less restrictive alternatives

Evidence of an alternative that is introduced must be considered; the court may deny a guardianship on a finding that one exists (R.C. 2111.02(C)(5)-(6)). Limited guardianship is considered before plenary (Sup.R. 8.34(A)).

Emergency guardian

If the person is not already under guardianship, an emergency exists, and it is reasonably certain that immediate action is required to prevent significant injury to the person or estate: maximum seventy-two hours, extendable after notice and hearing for good cause by no more than an additional thirty days (R.C. 2111.02(B)(2)-(3)).

Bond and reports

Court-fixed bond before letters issue; a guardian of the person only need not give bond unless the court finds good cause (R.C. 2109.04). Estate inventory within three months (R.C. 2111.14(A)(1)). Guardian's report two years after letters and biennially after that, with an expert evaluation within three months before the report (R.C. 2111.49(A)(1)).

Suggested Compliance Checklist

Weigh less restrictive alternatives

Before filing days after starting

Ask whether a durable power of attorney or healthcare power of attorney, or a limited guardianship, would meet the need. A written nomination of guardian under R.C. 2111.121 does not replace guardianship but is considered by the court. The court must consider evidence of a less restrictive alternative once it is introduced, and may deny a guardianship on a finding that one exists.

Document: durable-power-of-attorney

Obtain Form 17.1 from a physician or clinical psychologist

Before filing the application days after starting

Ask a licensed physician or licensed clinical psychologist to complete Form 17.1, Statement of Expert Evaluation. It must be completed before the application is filed; Sup.R. 8.31(A) alternatively allows a statement that the person refused to be examined. The probate court will not pay the evaluation fee unless it orders otherwise.

File Form 17.0 with the probate court

At filing days after starting

File Standard Probate Form 17.0 with the Form 17.1 evaluation (or a refusal statement) and Form 15.0 (next of kin) in the probate court of the county where the person resides or has a legal settlement. Ask the clerk about local forms and the filing fee.

Confirm notice and prepare for the hearing

Generally at least seven days before appointment days after starting

No guardian of an incompetent may be appointed until at least seven days after written notice of the hearing is served, unless the court finds good cause after service (interim and emergency guardians are exempt). Confirm the investigator has served the person and that next of kin known to reside in Ohio receive notice. The person may choose counsel; if indigent, on request, counsel and an independent expert are appointed at court expense.

Calendar bond, inventory and reports

After letters issue days after starting

File the court-fixed bond before letters issue (a guardian of the person only need not unless the court finds good cause). A guardian of the estate files an inventory within three months after appointment. The guardian's report is due two years after letters issue and biennially after that, with an expert evaluation within three months before the report.
