Idaho Guardianship and Conservatorship
When an adult can no longer manage their own care or finances, a Idaho court can appoint someone to decide for them. This guide explains the process, the alternatives to consider first, and the costs.
Based on Idaho Code 15-5-101 through 15-5-435 (Title 15, Chapter 5, Protection of Persons Under Disability and Their Property, in force until January 1, 2027), and Idaho Code 66-401 through 66-414 (Title 66, Chapter 4) for adults with a developmental disability
What guardianship and conservatorship mean here
Guardianship in Idaho is a district court case, heard in the magistrate division of each county, in which a judge gives another person authority to make personal decisions for an adult the court finds incapacitated, or for a minor. Money is handled separately: a conservator manages property under a protective proceeding, and the court can appoint one, both, or neither. Idaho defines incapacity as a legal, not a medical, disability measured by what the person can actually do, and it tells judges to encourage maximum self-reliance and to act only as far as the person's real limitations require. Adults with a developmental disability follow a separate Title 66 procedure with a state evaluation committee. The whole guardianship chapter is being replaced by the Uniform Guardianship, Conservatorship, and Other Protective Arrangements Act on January 1, 2027, so a case filed today runs under the current rules described here.
Idaho uses guardian for decisions about the person and conservator for money and property. The adult who has a guardian is the ward; the person who has a conservator, or is covered by another protective order, is the protected person. A guardian ad litem is different again: in an adult case the court-appointed attorney for the person has a guardian ad litem's powers and duties. Title 66 uses partial and total guardian or conservator for adults with a developmental disability, where Title 15 speaks of limited and general guardianship.
Because guardianship removes legal rights, courts look first at the less-restrictive alternatives below.
Types of guardianship and conservatorship
Conservatorship (Protective Proceeding)
A separate court proceeding over money and property. The court may appoint a conservator, or make another protective order, when a person cannot manage property and affairs effectively for reasons such as mental illness, disability, physical illness, chronic drug use or intoxication, confinement or disappearance, and the property will be wasted without management or funds are needed for support. The conservator holds title to the property as trustee. An order that vests only part of the property creates a limited conservatorship. A protective order does not by itself remove the person's legal capacity.
Idaho Code 15-5-401(b); 15-5-420(a); 15-5-408(b)(5)
Guardianship of an Incapacitated Adult (Limited or General)
The court appoints a guardian to make personal decisions for an adult it finds incapacitated. Idaho measures incapacity by function, not diagnosis: the person must have suffered, be suffering, or be likely to suffer substantial harm because they cannot provide for food, clothing, shelter, health care or safety, or cannot manage property. The evidence has to come from acts, occurrences or statements within the 12 months before the petition, and isolated negligence or a choice made with informed judgment does not count. The petition may ask for a limited or a general guardianship, and the court may limit a guardian's powers at appointment or later, with the limits endorsed on the letters.
Idaho Code 15-5-101(a); 15-5-303(a); 15-5-304(d)
Co-Guardians
Instead of one guardian, the court may appoint no more than two co-guardians if that best serves the person and the two will work together. Parents of an incapacitated person are preferred as co-guardians unless they are unwilling or cannot serve the person's best interests. The order and the letters must say whether the co-guardians may act alone, must act together on named matters, or must always act jointly.
Idaho Code 15-5-304(c)
More guardianship types7 additional arrangements courts use in specific situations, with statute cites
Temporary Guardian of an Incapacitated Adult
Idaho's emergency appointment. After a guardianship petition is filed, the court may appoint a temporary guardian on substantial evidence of incapacity and a finding, by a preponderance of the evidence, that an emergency will likely cause immediate and substantial harm, where no one else can act. The same tool can replace a guardian who is not performing. Authority lasts no more than 90 days unless extended for good cause.
Idaho Code 15-5-310
Temporary Conservator
On an ex parte petition supported by a sworn statement that an emergency exists, the court may appoint a temporary conservator without a hearing, pending the final hearing. The appointment lasts no more than 90 days unless extended for good cause, and it must be filed together with a regular conservatorship petition. The temporary conservator preserves the assets and pays for the person's support and may not move assets out of the court's jurisdiction without a specific order.
Idaho Code 15-5-407A
Guardianship of a Minor (Court Appointment)
The court may appoint a guardian for an unmarried minor if all parental rights of custody have been ended by court order, or on a finding that the child has been neglected, abused or abandoned, or that the parents cannot provide a stable home. Failing to keep up a normal parental relationship without just cause for six months is prima facie evidence of abandonment. The child's best interests are the primary factor. A parent's military deployment is not by itself neglect or abandonment.
Idaho Code 15-5-204
Testamentary Guardian of a Minor
A parent may name a guardian for an unmarried minor in a will, along with alternates in order of priority. The appointment takes effect when the named guardian files an acceptance in the court where the will is probated, if no parent with the right to appoint is alive. If the named guardian does not accept within 30 days after the will is probated, declines, dies or stops acting, the next alternate may accept. A parent whose parental rights were terminated loses the right to name a guardian.
Idaho Code 15-5-202; 15-5-203
Testamentary Guardian of an Incapacitated or Developmentally Disabled Adult
A parent, or the spouse of a married person, may name by will a guardian for an adult who is incapacitated or developmentally disabled. The named guardian gives seven days' written notice to the person and to their caregiver or nearest adult relative, then files an acceptance in the court where the will is probated. A parent's appointment works only if both parents are dead or the surviving parent has been adjudged incapacitated, and a spouse's appointment outranks a parent's. The person can end the appointment by filing a written objection, which does not stop a court from appointing the same nominee after an ordinary proceeding.
Idaho Code 15-5-301
Partial or Total Guardianship of an Adult with a Developmental Disability
A separate track under Title 66, Chapter 4. Idaho's ordinary definition of an incapacitated person excludes a developmentally disabled person as defined in Section 66-402, so these cases follow Section 66-404. The court appoints an attorney and a Department of Health and Welfare evaluation committee of at least three people designated by the department director, which must include a physician (a licensed independent practitioner may stand in for the physician in a 66-404 case), a licensed social worker or licensed professional counselor, and a clinical psychologist or another person with a master's degree in psychology designated by the director (66-402(7)). If the person can manage some affairs, the court appoints a partial guardian or conservator and the person keeps every right the order does not take away. A total guardian is appointed only when a partial one would not be enough. This track is repealed on January 1, 2027, when the new Chapter 5 absorbs it.
Idaho Code 66-404; 66-405; 66-402(7); 15-5-101(a)
Conservatorship for a Minor, Extendable to Age 21
A conservator may be appointed for a minor who owns money or property that needs management, has business affairs minority could jeopardize, or needs funds for support and education. If the appointing order or a supplemental order made before the minor turns 18 says so, the conservatorship can continue to age 21. After turning 18 the young adult may petition to end it early, but must prove by clear and convincing evidence the ability to manage their own finances.
Idaho Code 15-5-401(a); 15-5-433
The Idaho guardianship court process
1Consider the less restrictive options firstIdaho courts must use their guardianship powers to encourage maximum self-reliance and independence and may act only to the extent the person's actual limitations require.
2File the petition in the right countyThe person alleged to be incapacitated, or anyone interested in their welfare, may petition for a finding of incapacity and appointment of a guardian or co-guardians, limited or general.
3Include a care planThe petition must include a plan, in reasonable detail, for what the guardian will do after appointment.
4The court appoints an attorney, an examiner and a visitorOnce the petition is filed the court sets a hearing and, unless the person already has a lawyer of their own choice, appoints an attorney who also has the powers and duties of a guardian ad litem.
5Complete the background check and disclosuresNo one may be appointed guardian of an incapacitated person until they have submitted to, and paid for, a criminal history and background check run through the Department of Health and Welfare, and given the visitor, the guardian ad litem and everyone entitled to notice a report of their civil judgments and bankruptcies.
6Give notice of the hearingThe person alleged to be incapacitated must be served personally.
7Attend the hearingThe proposed guardian must attend unless the court excuses them for good cause.
8Findings and the order of appointmentThe court may appoint a guardian if satisfied that the person is incapacitated and that the appointment is necessary or desirable to provide continuing care and supervision.
9Accept the appointmentBy accepting, the guardian submits personally to the court's jurisdiction in any later proceeding about the guardianship brought by an interested person.
10Open a conservatorship too if money needs managingA guardian may start a conservatorship but may never exercise a conservator's powers.
11Report and account to the courtA guardian reports to the court at least once a year on the person's status, under oath and in the form the Idaho Supreme Court rules require.
12Modify or end the guardianshipThe person, the guardian, or anyone interested may petition to end or change the guardianship if the person no longer needs it or the powers granted are too broad or too narrow.
How long it takes
Idaho's in-force statute does not set a deadline for the adult guardianship hearing, so how long a case takes depends on the county's calendar, on how quickly the attorney, examiner and visitor file their reports, and on whether anyone objects. The fixed intervals give the outline. A temporary guardian can be appointed without notice, with notice to follow within 72 hours and a hearing within 14 days of a request, and serves up to 90 days unless extended. The guardian ad litem's written report is due at least five days before the hearing. If the care plan was not complete at filing, the guardian files it within 30 days after appointment. A conservator's inventory is due within 90 days of appointment and the first annual report follows. A minor guardianship is faster by statute: a hearing on either the temporary or the full petition must be held within 90 days of filing.

Alternatives to consider before guardianship
Durable Financial Power of Attorney
An Idaho power of attorney made under the Uniform Power of Attorney Act is durable unless it says it ends on incapacity. It must be signed by the principal, or by another person in the principal's conscious presence at the principal's direction, and acknowledging it before a notary makes the signature presumed genuine. It can also nominate a conservator, and that nominee ranks second for appointment if a conservatorship is ever needed. A court appointment of a conservator ends the power of attorney unless the court orders otherwise, so the document avoids a conservatorship only while it is working.
Idaho Code 15-12-104; 15-12-105; 15-12-108
Advance Care Planning Document Naming a Health Care Agent
Any competent adult may sign an advance care planning document. It needs only the person's name, date of birth, phone number and mailing address, their signature or that of an authorized agent, and the date. Naming one or more health care agents, witnesses and notarization are all optional. Under Idaho's consent statute a health care agent named in such a document may consent to care for a person who cannot consent, ranking just after a court-appointed guardian, which can make a guardianship for medical decisions unnecessary.
Idaho Code 39-4510; 39-4504(1)
Health Care Consent by Family Without a Guardian
When an adult cannot consent to care and has no guardian or health care agent, Idaho lets a spouse, then an adult child, then a parent, then a person named in a parent's delegation of authority under Section 15-5-104, then another relative, and finally any other competent person who takes responsibility for the person's care, consent in that order, so long as they do not go against the person's own advance care planning document or earlier wishes. Many families never need a guardian for medical decisions for this reason.
Idaho Code 39-4504(1)
Protective Arrangement or Single Transaction Without a Conservator
Where the grounds for a conservatorship exist, the court may skip appointing a conservator and instead authorize, direct or ratify a single transaction or arrangement, such as paying or holding funds, selling or leasing property, buying an annuity or a life care contract, or setting up or adding to a suitable trust, including a special needs trust under Title 68, Chapter 14. The court weighs creditors' and dependents' interests and whether ongoing protection is really needed, and it may appoint a special conservator only to carry the arrangement out.
Idaho Code 15-5-409
Temporary Delegation of a Parent's or Guardian's Powers
A parent, or the guardian of a minor or incapacitated person, may delegate powers over care, custody or property, including medical and educational decisions, by a power of attorney for up to six months, or up to twelve months for military personnel serving outside the United States. The power to consent to marriage or adoption cannot be delegated. A delegation to a grandparent, a sibling of the minor, or a sibling of either parent lasts as long as the document says, or three years if it says nothing. The document does not need to be notarized or recorded.
Idaho Code 15-5-104
Payment of a Minor's Money Without a Conservator
Someone who owes money or personal property to a minor may pay up to $10,000 a year to the minor if 18 or married, to the person with care and custody who lives with the minor, to the minor's guardian, or into a federally insured savings account in the minor's name alone. Whoever receives it must use it for the minor's support and education and turn any balance over at majority. The route closes once the payer knows a conservator has been appointed or a petition is pending.
Idaho Code 15-5-103
Limited Guardianship Instead of a General One
Where some protection is needed, the court may limit a guardian's powers at appointment or later, on its own motion or at the request of the person or anyone interested, and the limits appear on the letters of guardianship. The guardian ad litem is directed to recommend a suitably limited guardianship where that is enough.
Idaho Code 15-5-304(d); 15-5-315(8)
Representative Payee for Benefit Income
When the only money at stake is a government benefit, the paying agency can appoint someone to receive and manage it without any court case. Apply to the agency that pays the benefit, such as the Social Security Administration or the Department of Veterans Affairs.
Planning ahead: naming a guardian in advance
Naming a guardian in advance: Idaho has no separate statutory nomination-of-guardian form, but the law gives an adult three ways to shape the choice in advance. The person the incapacitated adult prefers must be appointed guardian unless there is good cause against it, and if they can no longer say, the court may look at any earlier expression of their wishes, including a durable power of attorney for health care. A health care agent named in that document ranks second for appointment as guardian. For money, a financial power of attorney may nominate a conservator, and that nominee, or the agent if no conservator is named, ranks second for appointment as conservator. Naming a health care agent and signing a financial power of attorney that nominates a conservator are the planning steps that give an Idaho adult the most say over who would serve.
Guardianship costs
- Court filing fee
- $216 to open a guardianship or a conservatorship case for a minor or an incapacitated adult, statewide, under the Idaho Supreme Court's fee schedule. A joint guardianship and conservatorship petition by the same person is also $216; separate petitioners for the two roles pay $262. An objection filed by the minor or the person alleged to be incapacitated carries no fee.
- Annual reporting fees
- $25 for each guardian status report. $41 for a conservator's inventory and $50 for each conservator accounting.
- Background check
- Paid by the proposed guardian, who must also pay for any court-ordered checks on others living in the proposed home.
- Attorney for the person
- The court appoints one unless the person has their own lawyer. The estate pays reasonable fees, and the court may split costs among the parties if the estate cannot bear them. Typically $1,000 to $3,000 nationally for an uncontested appointment.
- Attorney fees for the petition
- $2,500 to $8,000 nationally for an uncontested case, more if contested. A person who brings or defends the case in good faith, win or lose, may recover necessary expenses and reasonable attorney's fees from the estate.
- Medical or capacity evaluation
- $300 to $2,000 nationally, depending on the examiner. The court-appointed physician or examiner is paid reasonable compensation from the estate if not otherwise paid.
- Court visitor
- Paid reasonable compensation from the estate if not otherwise paid. Where court staff provide visitor services, the recovered amounts go to the state guardianship and conservatorship project fund.
- Bond premium
- Only if the court requires a conservator's bond. Roughly 0.5 percent of the bonded amount a year is a common national rate; the Idaho default bond equals the capital value of the property plus one year's income, less restricted deposits and land the conservator cannot sell without an order.
- Annual reporting preparation
- Little beyond the filing fee if the guardian or conservator prepares the report; $500 to $2,500 a year nationally if an accountant or lawyer prepares it.
Costs vary by county and case. Verify current court fees with the local court.
