Adult Guardianship and Conservatorship Petition Requirements in Idaho

At a glance

Requirements one by one

Proceeding and state terminology

Through December 31, 2026, Idaho uses a guardian for the adult's personal affairs and a conservator or other protective order for property and financial affairs. Section 15-5-102 permits the district court to consolidate both proceedings for the same person, but their petitions, counsel rules, and evaluation structures remain different.

The terminology and numbering change on January 1, 2027. S 1240 replaces the existing chapter with the Uniform Guardianship, Conservatorship, and Other Protective Arrangements Act. The new act preserves separate personal and financial tracks and adds express protective arrangements instead of either appointment.

Who may file and where

Current § 15-5-303(a) lets the allegedly incapacitated person or anyone interested in that person's welfare seek a limited or general guardianship. Current § 15-5-404(a) lets the person to be protected, someone interested in the person's estate, affairs, or welfare, or someone adversely affected by ineffective property management seek a conservator or another protective order.

Current guardianship venue under § 15-5-302 is where the adult resides or is present, with an additional option in the county of a court that ordered an institutional admission. Current conservatorship venue under § 15-5-403 is the adult's Idaho residence or, for a nonresident, a place where property is located.

What the petition must contain

Current guardianship law focuses on the proposed care plan. Section 15-5-303(a) requires a reasonably detailed plan for the guardian's proposed actions to the extent known at filing. If the necessary health, emotional, and care information is not known or the petitioner is not the proposed guardian, the appointed guardian supplies the completed plan within 30 days after appointment.

Current § 15-5-404 requires the conservatorship petition to identify the petitioner, adult, existing guardian, nearest known relative, property and estimated value, compensation, insurance, pension or allowance, necessity, and the proposed conservator and priority basis. It also requires a financial plan to the extent known, with a completed version submitted with the 90-day inventory when necessary.

Effective January 1, 2027, §§ 15-5-302(2) and 15-5-402 replace those shorter requirements with detailed checklists. Both petitions disclose close family, caregivers, counsel, representative payees, guardians and conservators, trustees, veterans fiduciaries, health and financial agents, routine decision supporters, proposed appointees, alternatives considered, limited-versus-full relief, property, income, and communication supports.

Proof required for appointment

Current § 15-5-101(a) treats incapacity as a legal, functional condition rather than a medical label. It requires substantial-harm risk and material functional evidence from the 12 months before filing. Isolated simple negligence, improvidence, lack of resources, and acts based on informed judgment do not establish inability.

Current § 15-5-304(b) asks whether guardianship is necessary or desirable for continuing care and supervision. Current § 15-5-401(b) asks whether the adult cannot effectively manage property and whether property will be wasted or dissipated or protected funds are needed. Those current appointment sections do not state a specific evidentiary burden.

On January 1, 2027, the new standards in §§ 15-5-301 and 15-5-401(2) become expressly clear and convincing. Both test the adult's ability to receive and evaluate information or make or communicate decisions even with supports, the need or risk in the relevant domain, and the insufficiency of a protective arrangement or other less restrictive alternative.

Alternatives the court must address

Current § 15-5-303(a) calls for the form of guardianship that least interferes with legal capacity. Section 15-5-304(a) limits orders to actual mental and adaptive limitations. For property, § 15-5-409 allows a transaction, trust, payment, sale, contract, or other protective arrangement without appointing a conservator when continuing administration is unnecessary.

The 2027 act makes the alternatives screen a required element. Sections 15-5-301 and 15-5-401 prohibit guardianship or conservatorship when a protective arrangement, supported decision-making, appropriate technology, supportive services, or another less restrictive alternative can meet the identified need. Full authority is unavailable when limited authority will work.

Notice, service, and hearing timing

Current §§ 15-5-309 and 15-5-405 require personal service on the adult for both tracks. The same provisions identify the spouse or next listed relatives, existing guardian or conservator, caregiver or custodian, closest adult relative when necessary, and people who requested notice. The adult-personal- service provision states no numeric lead time. Other recipients ordinarily receive mail or personal delivery at least 14 days before the hearing under § 15-1-401, subject to the court's good-cause authority.

Effective January 1, 2027, §§ 15-5-303 and 15-5-403 require personal service of the petition and a notice explaining hearing rights and the nature, purpose, and consequences of appointment. Those new sections likewise state no numeric personal-service lead time.

Counsel and hearing rights

Current guardianship counsel is automatic unless the adult already chose a lawyer. Under § 15-5-303(b), appointed counsel also has guardian-ad-litem powers and duties. Subsection (c) gives the adult an in-person hearing right, access to the evidence, and rights to present evidence, subpoena witnesses and documents, examine the examiner and visitor, participate, and request closure for good cause.

Current conservatorship is different. Section 15-5-407(b) makes appointment of counsel discretionary and does not provide the parallel express attendance and participation list found in the guardianship section. The current initial- appointment provisions do not state a jury-trial right.

Starting January 1, 2027, § 15-5-305 keeps automatic guardianship counsel but makes the representation client-directed. Section 15-5-406 keeps conservator- ship counsel discretionary but imposes the same client-directed duties when a lawyer represents the adult. Sections 15-5-307 and 15-5-408(1)–(5) ordinarily require attendance, allow an alternative location or real-time audiovisual appearance, provide communication supports, and permit absence only on specified clear- and-convincing findings.

Medical evidence or court evaluator

Current guardianship uses three mandatory roles under § 15-5-303(b): counsel with GAL duties, a court-appointed physician or other qualified examiner who reports in writing, and a court visitor who interviews the adult, filing source, and proposed guardian, visits current and proposed residences, and reports. The court may add a mental-health professional.

Current conservatorship is less automatic. Section 15-5-407(b) says the court may appoint counsel, may order a physician examination for listed grounds, and may send a visitor.

The 2027 act changes the architecture again. Sections 15-5-304(1)–(2) and 15-5-405(1)–(3) require a visitor for an adult without a developmental disability or a developmental-disability evaluation committee for an adult with one, in both tracks. Sections 15-5-306 and 15-5-407 separately authorize a professional functional evaluation when requested or when the court needs more information.

Limits on the order

Under current §§ 15-5-304 and 15-5-408, personal and property orders promote maximum self-reliance and independence and extend only to actual limitations. The court may endorse limits on a guardian's letters. A current protective- order finding also has no effect on the adult's capacity under § 15-5-408(b)(5).

On January 1, 2027, §§ 15-5-301, 15-5-401, and 15-5-310(1), (3), (4) expressly bar full authority when limited authority or a protective arrangement works. A full guardianship order must explain, with specific clear-and-convincing findings, why a limited guardianship would not meet the adult's functional needs.

Temporary relief stays separate. Current § 15-5-310 requires substantial incapacity evidence, an emergency likely to cause immediate and substantial personal harm, and no available person able and willing to act; ex parte notice follows within 72 hours and temporary authority ordinarily cannot exceed 90 days. Current § 15-5-407A uses a separate emergency temporary conservator, 72-hour notice, and a 14-day hearing on request.

What trips people up

The current and future statutes are printed together. Idaho's official pages show one rule effective through December 31, 2026 and a different rule effective January 1, 2027. A 2026 filing uses the current text, not the new section with the same number.

Current counsel and evaluator rules differ by track. Guardianship requires counsel, an examiner, and a visitor. Conservatorship makes all three discretionary. The 2027 act keeps the counsel difference but requires a visitor or developmental-disability committee in both tracks.

The current guardianship plan and conservatorship financial plan are not the same document. The first addresses proposed personal care and decision-making; the second addresses assets, income, expenses, debts, and other financial concerns.

Common questions

Does the January 2027 act apply now?

No. S 1240 is enacted, but its effective date is January 1, 2027. The provisions labeled "effective until January 1, 2027" govern before then.

Is a diagnosis enough under current Idaho law?

No. Section 15-5-101(a) calls incapacity a legal, not medical, disability and requires recent functional evidence tied to substantial harm. It excludes isolated negligence, improvidence, lack of resources, and informed choices.

Is appointed counsel automatic in both current proceedings?

No. Current § 15-5-303(b) requires counsel in guardianship unless the adult has chosen counsel. Current § 15-5-407(b) says the court may appoint counsel in a conservatorship.

Can one financial problem be addressed without a conservator?

Yes. Current § 15-5-409 permits a protective arrangement or single transaction without appointing a conservator. The 2027 act expands and formalizes protective arrangements instead of conservatorship.
