Dad has a new friend. The friend drives him to the bank, handles a few errands and leaves with money. Dad says it is none of your business.

Local option: New Plan Care gives families in the St. Louis area in-home help so a parent can stay home: companionship, help with bathing and dressing, meals, and overnight care. Call (314) 405-0887.

He may be right. An adult can spend money badly, give generous gifts and trust somebody you would not trust. Age does not hand the family veto power.

But choice and exploitation can look remarkably similar from the driveway. The useful question is not whether the payment seems foolish. It is whether Dad chose it freely, understood what he was doing and received what he believed he was buying.

Start with the legal line

Missouri law describes financial exploitation in terms of knowingly obtaining control of an older or disabled person’s property through conduct such as deceit, coercion, a false impression or undue influence. The statute defines undue influence as using authority over someone to take unfair advantage of vulnerability, neediness, pain or distress. Improper use of a power of attorney or other fiduciary authority can qualify. (Missouri Revised Statutes, section 570.145.)

That is a higher bar than “Dad paid too much” or “Dad likes this person more than I do.” Failure to deliver a promised service, standing alone, does not establish that the person never intended to perform. The facts around the transaction matter.

This is general information, not a legal conclusion about Dad’s situation. If property, account ownership or signed documents are involved, a Missouri lawyer can review the actual papers.

Look for a control problem, not an annoying friendship

One odd payment is a reason to ask. A pattern of control is a reason to act.

Check for changes you can observe without entering accounts you are not authorized to access:

• The friend answers every question directed to Dad.
• Dad cannot speak with you privately.
• The friend has Dad’s debit card, checkbook, identification, phone or account passwords.
• Bills are unpaid even though Dad says money is available.
• Valuables have disappeared from the house.
• Dad describes a transaction differently each time.
• A new name appears on an account, vehicle title, deed or financial document.
• Dad is frightened that rides, meals, company or care will stop unless he pays.
• The friend is pushing a signature while preventing Dad from getting independent information.
• Dad says money was taken or used for something he did not approve.

Missouri Adult Protective Services identifies unusual withdrawals, missing records, changed names or addresses on accounts, purchases made without consent, newly authorized signatures, missing belongings and sudden changes to a power of attorney, trust, will, account or deed as warning signs. Federal elder justice guidance identifies similar signs, including unpaid bills despite available funds, unexplained transfers and a companion who will not let the older adult speak alone. These are indicators, not automatic proof. See the site’s source desk for the underlying public materials.

Ask Dad questions that leave room for a real answer

Do not begin with “That person is stealing from you.” If Dad chose the arrangement, you have accused his judgment and handed the other person a useful story about the interfering son.

Get Dad alone if you can do so safely. Then ask:

• What did you agree the person would do?
• How much did you agree to pay, and was it a gift or payment?
• Did you choose the amount yourself?
• What has already been delivered?
• Can you stop the arrangement whenever you want?
• Does anyone else have your card, PIN, checks, password or phone access?
• Did anyone tell you not to discuss this with me or the bank?
• Did anyone threaten to leave, stop helping or put you somewhere?
• Did you sign anything?
• Where is your copy?

You are listening for ownership of the decision. Dad should be able to explain, in his own rough way, what he gave, what he expected and whether he can say no. He does not have to give the answer you prefer.

Sort what you find into three buckets

Unpopular but apparently voluntary: Dad understands the arrangement, describes it consistently, can speak privately, has access to his own records and can stop. You may dislike it. That alone does not make it yours to cancel.

Unclear and worth checking: Dad is vague, no one can produce an agreement, services do not match the payments or the other person keeps inserting himself into the conversation. Ask Dad to pause new payments while an independent person reviews the paperwork. His bank may have a fraud or vulnerable-customer team, but the bank decides what it can disclose to you.

Possible exploitation: Dad reports theft, forgery, threats or unauthorized use. The person controls his access to money or communication. Property is moving while Dad appears confused about what he signed. Preserve facts and report the concern.

Do not commit your own access violation

Concern does not authorize you to guess Dad’s password, open his mail, impersonate him, move his money or take his cards. A spare house key is not financial authority. Being named in a power of attorney does not necessarily mean the document is effective, covers the transaction or permits action for your own benefit.

Use access Dad has actually granted. If he agrees, sit beside him while he calls the bank, requests statements or asks what names and permissions are on the account. Let the bank verify him. Ask the representative what the bank needs before it can speak with you later.

Build a clean fact sheet

If the concern survives the conversation, write one page. Record names, relationships, what Dad said, what you directly observed, the property involved, known transactions, documents signed and whether Dad can currently speak privately. Separate fact from inference.

“Dad said Lee took his card without permission” is a fact about Dad’s report. “Lee is a thief” is a conclusion. Agencies, banks and lawyers can work with the first sentence.

Preserve lawful copies of texts, receipts, envelopes, contracts and photographs already available to you. Do not confront the person alone if threats, weapons or physical intimidation are part of the situation.

Choose the next door

If Dad is in immediate danger, someone is threatening him or a theft is happening now, call emergency services.

For suspected exploitation of a Missouri adult who may be unable to protect his own interests, a concerned person can contact the Missouri Adult Abuse and Neglect Hotline at 800-392-0210. You do not have to prove the case before reporting a good-faith concern. Give concrete observations, not a family biography. The St. Louis local help page can help you identify the appropriate local door.

If Dad understands the transaction and wants help unwinding it, start with the bank or institution involved and ask what can still be stopped, recalled, disputed or secured. For a deed, beneficiary change, power of attorney, joint ownership or substantial transfer, ask a Missouri lawyer to review the documents before anybody signs a corrective paper.

Your next move tonight

Write down the three strongest facts you have, then ask Dad for ten private minutes. Use one opening line: “I am not here to take over. I need to know whether this was your deal, whether you understood it and whether you can stop it.” If his answer shows control, deception, fear or unauthorized access, make the report tonight. If it shows a voluntary choice, leave the argument alone and ask whether he will let you keep a copy of the agreement.
