Idaho: Challenging a Sibling’s Use of a Deceased Parent’s Bank Account Before an Administrator Is Appointed

Detailed Answer

Short answer: Yes, you can challenge a sibling’s use of your deceased parent’s bank account before an administrator is formally appointed, but what you should do next depends on how the account was titled and what the sibling did with the money. Idaho probate law treats funds in an account held only in the decedent’s name as estate property. If someone other than the authorized personal representative withdrew or used those funds for their own benefit (or without court authorization), you may have remedies in probate court and possibly in civil court. If the account was a joint account or payable-on-death (POD) with your sibling named, your sibling may have legal access to the funds automatically.

How Idaho law generally treats bank accounts after death

– Solely in the decedent’s name: Funds belong to the decedent’s estate and are subject to probate. Only a duly appointed personal representative (executor or administrator) or someone with court authority should distribute estate funds. Idaho probate is governed by the Idaho Probate and Estates statutes (Title 15). For an overview of the statutes, see the Idaho Legislature’s Probate and Estates section: Idaho Code Title 15 (Probate and Estates).

– Joint account with right of survivorship: The surviving co‑owner generally becomes owner of the funds immediately on death and can legally access them without probate.

– Payable-on-death (POD) or transfer-on-death: The named beneficiary can claim the funds directly, bypassing probate.

Was your sibling’s use lawful?

Key questions to determine whether you can successfully challenge their actions:

• How was the account titled (sole name, joint, POD)?
• Did the sibling use the money to protect estate interests (for example, to stop foreclosure on the family home) or for personal gain?
• Were there any communications or written authorization from the deceased (rare but relevant) or any court authorization?

If the account was solely in the decedent’s name and your sibling withdrew funds without court authority or letters of administration, those withdrawals are treated as taking estate property. If the sibling used the funds to pay a mortgage on property owned by the decedent’s estate, a court may view mortgage payment as a necessary expense of preserving estate assets—but the sibling must account for and justify the payments to the court. If the sibling used funds for their own personal expenses, you can challenge that use as improper and seek recovery.

Practical steps you can take right now in Idaho

1. Preserve evidence. Save bank statements, mortgage statements, emails, texts, and any other records that show withdrawals, transfers, or directions about the account or the mortgage payments.
2. Contact the bank. Provide a copy of the death certificate and ask whether the bank froze the account or requires letters testamentary/letters of administration before allowing further withdrawals. Many banks will freeze accounts or place a hold until the probate court issues authority.
3. Consider filing for appointment of a personal representative (administrator) promptly. If there is no estate representative yet, any interested person (including heirs) may petition the Idaho probate court to be appointed. The appointed representative will obtain letters that give legal authority to manage estate assets. See the Idaho courts’ self-help and probate resources for filing procedures: Idaho Courts – Self-Help (Probate).
4. If the estate is at risk of asset loss, ask the court for emergency relief. You can ask the probate court for temporary orders (for example, to appoint a temporary administrator, to restrain further withdrawals, or to require an immediate accounting) to preserve estate assets. Courts can issue interim remedies to prevent dissipation of estate property while the administration proceeds.
5. File a petition for accounting and surcharge if needed. Once a personal representative is appointed, the court can require the sibling (or anyone who handled estate assets) to provide an accounting. If the court finds wrongful taking or misuse, it can order repayment, surcharge the person’s share, or remove them from any role of authority over estate assets.
6. Consider civil claims (conversion, unjust enrichment) or criminal referral. If the sibling knowingly took estate funds for personal use, you may have a civil claim for conversion or unjust enrichment. In extreme cases, criminal theft may apply—contact local law enforcement if criminal conduct is suspected.

What courts look at

The court will examine the title of the account, the nature of withdrawals, whether the payments benefited the estate, and whether actions taken were reasonable to preserve estate assets. Honest, documented payments to protect estate property (for example, mortgage payments to avoid foreclosure) are more likely to be treated differently than payments used for the sibling’s personal benefit without accounting.

Timing and typical outcomes

Act promptly. Probate courts prefer to preserve estate assets and may act quickly when an interested person shows a risk of dissipation. Common outcomes include: the bank freezing the account until a representative is appointed; the appointment of a temporary or permanent personal representative; orders requiring the sibling to account for and repay improper withdrawals; removal of a person who misused estate assets; and civil remedies for conversion or restitution.

Idaho law gives probate courts the tools to protect estates and to remedy improper handling of estate property under Title 15 of the Idaho Code.

Helpful Hints

• Determine account title immediately: joint, POD, or solely in the decedent’s name—this usually decides who has access.
• Get a certified copy of the death certificate—banks and courts will require it.
• Call the bank and ask whether the account is frozen; if not, ask them to preserve records and place a temporary hold until probate begins.
• File a petition for appointment of a personal representative if one has not been appointed—this gives legal standing to manage and protect estate assets.
• If the sibling spent money to prevent foreclosure, document the timing and purpose of those payments; the court will want to know whether the payments protected estate property.
• Keep detailed copies of all communications with the sibling, the bank, mortgage lender, and the court—every message can be useful evidence.
• Act quickly—courts are more likely to grant emergency protection if you show a present risk to estate assets.
• Talk to a probate attorney in Idaho if the amounts are significant or the facts are contested; an attorney can file emergency motions and guide you through local rules and deadlines.
