Seeking Guardianship of a Relative's Children in Idaho

Attorney Answer

You can file, and as an aunt or uncle you are exactly the kind of person Idaho law lets petition. But be clear about the standard before you spend money on it: an Idaho court cannot appoint you guardian simply because your home is better. The statute requires that the children have been neglected, abused, or abandoned, are without a stable home, or that parental rights have already been terminated.

Idaho Code § 15-5-207 lets a relative of a minor petition for appointment of a guardian — as may any interested person, and as may the minor personally if fourteen or older, which your fifteen-year-old niece and nephew are. The petition requires notice to the minor, to whoever has had the minor's principal care and custody during the preceding sixty days, and to any living parent. The court may appoint on findings that the proposed guardian is qualified, that venue is proper, that notice was adequate, and that the appointment serves the minor's best interests. Idaho Code § 15-5-204 adds the threshold that actually decides most of these cases: a guardian may be appointed for a minor only where parental rights have previously been terminated, or the child has been neglected, abused, abandoned, or is without a stable home. It also permits appointment of a temporary guardian to protect a child's health, safety, or welfare while the petition is pending.

One administrative warning. These section numbers are correct today but are replaced effective January 1, 2027, when Idaho's new guardianship act takes over Title 15, Chapter 5. The new § 15-5-204 is an entirely different provision about appointment of an attorney, so anyone who looks up the number after that date will land on the wrong text.

In Murray v. Dalton the Idaho Supreme Court set out the standards that govern these proceedings. It held that the burden of proof in a permanent guardianship case is preponderance of the evidence, not the clear-and-convincing standard used for terminating parental rights, because a guardianship changes who cares for a child during minority rather than permanently severing the relationship. It held that Idaho Code § 15-5-212 must be read together with § 15-5-204, so the same threshold harm finding is required. It held that the parental-preference presumption limits best-interests review unless the nonparent shows abandonment, unfitness, or that the child has been in the nonparent's custody for an appreciable period. And it applied the best-interests factors in Idaho Code § 32-717. The Court affirmed a refusal to end a grandmother's guardianship over the mother's objection — that case arose on a petition to terminate an existing guardianship rather than to create one, so treat those holdings as the standards for guardianship proceedings generally.

You should also see how these cases go when the threshold is not met. In In re Guardianship of Copenhaver the Idaho Supreme Court reversed a permanent guardianship and ordered the children returned to their mother, because she had made her whereabouts known and was willing and able to care for them. The nonparents lost. Copenhaver remains good authority for the parental-preference presumption and its three escape hatches, and for the point that a guardianship is not a termination of parental rights — a parent can come back and ask for custody to be restored. Its older statutory language about appointment has since been superseded, so do not rely on it for the appointment standard itself.

On cost: there is a filing fee set by the court, and Idaho courts have a process for waiving fees for people who cannot afford them. Beyond that, the real variable is whether the mother contests. An uncontested guardianship where the parent consents is comparatively inexpensive. A contested one — with hearings, possibly a guardian ad litem or attorney appointed for the children, and costs that can be charged to the parties — is a different order of expense. The magistrate court clerk in the county where the children live can give you the current filing fee and the fee waiver form.

What you can do

1. If the children are in immediate danger right now, call law enforcement or report to the Idaho Department of Health and Welfare. Do that before anything else and do not wait for a court process. 2. Write down the specific facts, with dates: what you have seen, what the children have told you, missed school, missed medical care, who else was in the home, any police contact. Idaho Code § 15-5-204 turns on neglect, abuse, abandonment, or the absence of a stable home, and general concern about the mother's parenting will not get you through that gate. Specific dated incidents will. 3. Talk with the twins. At fifteen they can petition on their own behalf under Idaho Code § 15-5-207, and they must receive notice of any petition. What they want and what they will say matters. 4. Go to the magistrate division in the county where the children live. Ask the clerk for the guardianship of a minor packet, the current filing fee, and the fee waiver application. 5. Ask specifically about a temporary guardian under Idaho Code § 15-5-204 if the situation cannot wait for a full hearing. 6. Identify every person entitled to notice, including both living parents and whoever has had the children's principal care in the last sixty days. Defective notice is the most common reason these petitions stall. 7. Talk to a family law attorney about whether the facts you have actually meet the § 15-5-204 threshold before you file. That one conversation is the cheapest part of this and may save you the rest.
