A Notice of Assignment by Assignor to Debtor is a legal document that assigns the rights of a debt from one party (the assignor) to another party (the debtor). It is used to transfer the rights to collect a debt from one party to another. The document typically includes the name of the assignor, the name of the debtor, the amount of the debt, a description of the debt, and the date of the assignment. The notice of assignment must be signed by both parties to be valid. There are two types of Notice of Assignment by Assignor to Debtor: voluntary and involuntary. A voluntary assignment is when the assignor voluntarily agrees to assign the debt to the debtor. An involuntary assignment is when the assignor is required, by law, to assign the debt to the debtor.
