To protect the money of a parent with dementia from a sibling who may be misusing it, write down what you see, help secure bank accounts, and report suspected exploitation to Adult Protective Services and local police. A power of attorney — a legal paper that lets one person handle another person's money — does not allow personal spending. If misuse continues, only a court can assign new financial control once your parent can no longer make legal decisions.
Dementia can remove the ability to track bills, spot missing cash, or question pressure to sign. That loss of oversight can give a nearby sibling easy access to cards, checks, online accounts, and deeds. Quick records and outside reports create protection your parent can no longer provide alone.

What crosses the line?
A fiduciary — a person legally trusted to manage someone else's money, such as a power-of-attorney agent or court-appointed guardian — must act only in the parent's best interest. The Consumer Financial Protection Bureau explains that duty includes managing property carefully, keeping funds separate, and keeping records in its fiduciary duties guide. Misuse includes theft by ATM, check, or cash, forgery, and using a power of attorney to benefit oneself.
Gifts to the sibling, personal bills paid from the parent's account, and transfers of a house or car are warning signs. A pattern of unusual withdrawals, new "loans," or missing statements also deserves attention. A sibling who uses a parent's power of attorney for personal spending, gifts, or asset transfers violates that duty. Such conduct can lead to a civil order to repay and criminal charges for theft, fraud, or embezzlement.
What can you do right now?
Start by listing accounts, cards, deeds, loans, and regular bills. Save recent bank and card statements and note dates, amounts, and who benefited from each unusual transaction. Keep originals safe and work from copies when you talk to others.
Act calmly and avoid taking money back yourself. Alert the parent's bank to your concern and ask about fraud protections. Keep your notes factual and ongoing, because small details often connect later.
- List every bank, card, loan, deed, and income source
- Flag unusual withdrawals, new payees, and missing mail
- Ask the bank how to add alerts and limit access
- Keep a dated log with receipts, photos, and messages
- Follow the Managing Someone Else's Money guides for agents and guardians
Who should you call for help?
Report suspected sibling exploitation to your state or local Adult Protective Services agency. The Consumer Financial Protection Bureau's reporting guide directs families to find that agency through the federal Eldercare Locator at 1-800-677-1116 in its reporting elder financial abuse guide. Call local police if money is disappearing now or your parent feels threatened.
Call 911 when there is immediate danger. Fraud can also be reported to the Justice Department Elder Fraud Hotline at 1-833-372-8311 and to the FBI online complaint center. Give each agency the same clear packet: dates, amounts, account records, and names of witnesses. Keep the case numbers and the name of each person you speak with.
What if your sibling controls the paperwork?
A parent can revoke or replace a power of attorney only while they still have legal capacity. The Consumer Financial Protection Bureau explains that after dementia removes capacity, no new power of attorney can be signed and only a court can grant financial authority in its guardian of property explainer. A court can name a guardian of property or conservator after finding the parent cannot manage money alone. The court, not the family, chooses who serves and sets their powers, with ongoing court oversight.
This process can be slow and costly. Adult Protective Services investigates and refers cases but does not award custody of money. Preserve records and consult an elder-law attorney about asking the court to remove an abusive agent and recover funds. Keep copies of statements, notes, and letters in one folder for investigators and the attorney.
