Money is usually where families get this wrong. A parent pays an adult child for help at home, everyone calls it "just helping out," and later Medicaid or other heirs may treat those payments as gifts, not wages. That can trigger tax problems, family disputes, or a penalty period that delays long-term-care coverage. A caregiver agreement is a written contract that sets out the services one person will provide for another, how often, and how much will be paid.

Despite the casual name, this is not a handshake deal with scribbled notes. A solid agreement usually identifies the parties, lists tasks such as meals, transportation, bathing, or medication reminders, states the pay rate, explains when payment is due, and shows that the rate is reasonable for the work. It may also address backup care, mileage, recordkeeping, and when the arrangement ends. If the caregiver is being treated as an employee, wage and tax rules can apply.

For an injury claim or elder-care case, the agreement can help prove the value of care after a fall, crash, or other serious event. Without one, insurers and opposing parties may argue the help was free or exaggerated.

In Iowa, this can directly affect Medicaid eligibility. Payments made without a valid care contract may be treated as transfers for less than fair market value under Medicaid transfer-of-assets rules, creating a penalty period under federal law, 42 U.S.C. § 1396p, as applied by the Iowa Department of Health and Human Services.
