The term used legally for the amount of money paid or deposited to the court clerk by the person, who owes that money to the party of the lawsuit ( he himself is not the party) but is not sure whom should he pay. The court holds the funds till the dispute between the two party is resolved and it is decided who is to receive the accounts receivable. Generally such cases occur when say the firm collecting the rent have their partners fighting a case over dissolving the firm and dividing the property. In such case the tenant does not know whom to pay the rent, but knows that he owes the monthly rentals. He goes to the court and deposits the rent with the clerk as if stating that I have fulflled my debts thus keep me out of your arguments. Whoevers wins may collect the rent from the court.
