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 or agent
• A guardian, conservator, or other fiduciary acting for the principal
• A person authorized to make healthcare decisions for the principal
• The principal's spouse, parent, or descendant, or a presumptive heir
• A beneficiary with a financial interest in the principal's estate or a trust created by or for the principal
• A governmental agency with regulatory authority to protect the principal's welfare
• A person aware of pending criminal charges or an investigation of dependent-adult abuse related to the agent
• The principal's caregiver, or another person with sufficient interest in the principal's welfare
• A person asked to accept the POA or designated by the principal in the POA

A sibling may petition if they qualify as a presumptive heir or another statutory category applies; being named or not named in the POA is not by itself dispositive.

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, and disbursements — and review the agent's conduct.

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 following the principal's known expectations.

Suspend the agent in an abuse proceeding: If the petition concerns pending criminal charges or an investigation of dependent-adult abuse related to the agent, the court may suspend the agent's power of attorney and appoint a guardian ad litem. A permanent change in authority may require revocation by the principal or a guardianship/conservatorship proceeding.

Award reasonable attorney fees and costs: The court may award reasonable attorney fees and costs to the prevailing 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, suspension where authorized, or other available relief).

4. Court hearing. The judge hears both sides, reviews the evidence, 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.
