In Louisiana, there are two potential time periods that apply. For "open accounts" the prescriptive period is three years. An open account is a revolving account used to obtain goods and services - usually a credit card. For contracts, the prescriptive period is ten years. Now, if you have not been billed for 22 years, and you or your father have not made a payment in over 10 years, it seems unlikely they can do anything from a legal standpoint. They likely will need a power of attorney before they discuss your father's debt with you. Further, there are certain actions you will want to take to prevent this company from harassing you.
