A Letter of Attornment is a legal document that serves to transfer the rights of one party to another. It is generally used in situations where the person or entity relinquishing their rights does not have any other legal recourse to do so, or when the two parties have a complex relationship. There are two main types of Letter of Attornment. A voluntary Letter of Attornment occurs when a person or entity willingly transfers their rights to another. This is often done when a party is selling a real estate property or a business. The other type of Letter of Attornment is involuntary, and occurs when a party is forced to transfer their rights due to a court order. This type of attornment is typically used in cases of bankruptcy, foreclosure, or other legal proceedings. Regardless of the type of Letter of Attornment being used, they all contain the same basic information including the names of both parties, the rights being transferred, the date of the attornment, and any signatures of the involved parties.
