An Illinois Order For Payment (IFP) is a legal document issued by a court in Illinois to order a person or business to pay a certain amount of money to another individual or business. The IFP is a form of legal enforcement used to collect a debt or resolve a dispute between two parties. There are two types of IFP — an order to pay an overdue debt and an order to pay a judgment or award. An Order To Pay An Overdue Debt can be used to collect an overdue debt such as a loan or a bill, while an Order To Pay A Judgment Or Award is used when a court has decided that one party owes the other a certain amount of money, such as in the case of a divorce or a civil lawsuit.
