Sibling Disputes Over Power of Attorney in Iowa: Legal Options Under § 633B.116

Your brother has financial power of attorney for your mother. Last month, $12,000 disappeared from her savings account. He says it was for "home repairs" but can't produce a single receipt. You're suspicious — and you have no idea what legal options exist when a POA agent may be abusing their authority in Iowa.

Iowa Code § 633B.116 provides a specific statutory mechanism for exactly this situation. It's the relief valve for families where the designated agent may not be acting in the principal's best interests.

Who Can Challenge a POA Agent in Iowa?

Under § 633B.116, the following individuals have standing to petition the Iowa District Court regarding a power of attorney:

• The principal (your parent) — if they retain some capacity
• The agent named in the POA
• A person nominated as successor agent
• A spouse, parent, or descendant of the principal
• A presumptive heir of the principal (anyone who would inherit if the principal died today)
• A person who has an interest in the principal's estate
• A caregiver providing services to the principal
• A governmental agency with regulatory authority

This means any sibling — regardless of whether they were named in the POA — can petition the court to review the agent's conduct. You don't need to be the designated agent or successor to challenge.

What the Court Can Do

When you file a petition under § 633B.116, the court can:

Demand a full accounting: The court can compel the agent to produce a complete financial record of every transaction made under the POA — bank statements, receipts, contracts, disbursements. The agent bears the burden of proving each transaction served the principal's interests.

Construe the POA: If the scope of the agent's authority is disputed ("Does the POA allow them to gift assets to themselves?"), the court interprets the document's terms and rules on what the agent is and isn't authorized to do.

Review the agent's conduct: The court evaluates whether the agent is fulfilling their fiduciary duty — acting in the principal's best interests, avoiding conflicts of interest, keeping the principal's funds separate from their own, and making decisions the principal would have made.

Remove the agent: If the court finds breach of fiduciary duty, self-dealing, or neglect, it can revoke the agent's authority entirely. The successor agent (if named) steps in, or the court can appoint a guardian/conservator if no successor exists.

Award damages and attorney fees: The court can order a bad-acting agent to reimburse the estate for misused funds, and may award reasonable attorney fees to the petitioning party.

Grounds for Challenging an Agent

Courts generally sustain challenges when the evidence shows:

• Self-dealing: The agent is using POA authority to benefit themselves rather than the principal (paying themselves excessive "management fees," gifting estate assets to themselves, using the principal's funds for personal expenses)
• Failure to account: The agent refuses to share financial information with other family members or cannot explain where funds went
• Commingling: The agent has mixed the principal's funds with their own personal accounts
• Neglect of duty: The agent isn't paying the principal's bills, isn't managing necessary care, or is ignoring the principal's known wishes
• Conflicts of interest: The agent has a financial interest that conflicts with the principal's (selling the principal's home to themselves at below market value)

The Practical Process

1. Gather evidence first. Before petitioning the court, document everything you can access: bank statements showing suspicious activity, property records, communications where the agent refused to provide information, and any witnesses to concerning behavior.

2. Send a written demand for accounting. A formal letter requesting that the agent provide a full financial accounting of all transactions made under the POA. If they refuse, this refusal becomes evidence in your petition.

3. File the petition. Submit your petition to the Iowa District Court in the county where your parent resides. Include your evidence and specify what relief you're requesting (accounting, removal, damages).

4. Court hearing. The judge hears both sides. The agent must justify their actions. The court makes findings of fact and issues an order.

Prevention: Structuring POAs to Reduce Sibling Conflict

The best time to prevent disputes is when the POA is first drafted:

• Require annual accountings in the POA document itself — not just when a court orders it
• Name an independent third party (an accountant, attorney, or trust company) as a monitoring agent who can demand records
• Include explicit gift limitations — prevent the agent from making gifts to themselves or family members without prior written consent from the principal
• Designate a successor clearly — so removal of a bad agent doesn't leave a vacuum
• Add co-signature requirements for transactions above a threshold (e.g., any withdrawal over $5,000 requires a second signature)

When Disputes Escalate to Dependent Adult Abuse

If you believe the financial exploitation rises to the level of criminal conduct — systematic theft, coercion, or fraud against a vulnerable adult — you have a parallel reporting option. File a dependent adult abuse report with Iowa HHS (1-800-362-2178). The state investigates independently of any civil court action.

Founded reports of financial exploitation can result in criminal charges against the agent, in addition to the civil remedies available under § 633B.116.
