20 C.F.R. § 255.12
(b) For purposes of this section, income includes any funds which may reasonably be considered available for the individual's use, regardless of source, including inheritance prospects. Income to the individual's spouse or dependents is available to the individual if the spouse or dependent lived with the individual at the time waiver is considered. Types of income include but are not limited to:
(c) For purposes of this section, resources may include:
(d) Whether an individual has sufficient income and resources to meet ordinary and necessary living expenses depends not only on the amount of his or her income and resources, but also on whether the expenses are ordinary and necessary. While the level of expenses which is ordinary and necessary may vary among individuals, it must be held at a level reasonable for an individual who is living on a fixed income. The Board will consider the discretionary nature of an expense in determining whether it is reasonable. Ordinary and necessary living expenses include:
(f) This section may be illustrated by the following examples:
Example (1).A remarried widow, W, is overpaid $6000 due to receipt of benefits on the wage records of both her late husbands. It has been determined that she is without fault. Her financial disclosure statement reveals monthly income greater than monthly expenses, and assets of $12,000, $10,000 of which is in cash. She claims to be saving these funds for future medical expenses, because she has a progressive disease. While it is not necessarily contrary to the purposes of the Act to recover the overpayment in these circumstances, the legitimate medical expenses associated with the disease must be considered.
Example (2).A disability annuitant, D, is overpaid $33,000 because of simultaneous entitlement to workers' compensation payments. He is determined to be without fault. He claims he has assumed financial responsibility for his adult child and her children. A claimed expense for which the annuitant has no legal obligation to pay does not make recovery contrary to the purposes of the Act.
