A Security Instrument Addendum is a legal document that is added to a mortgage or deed of trust, which outlines the terms and conditions of a loan security instrument. It serves to modify, clarify, or supplement existing terms, and is typically created to provide additional details about the security instrument. Security Instrument Addendums can also be used to add or remove parties from the agreement. Common types of Security Instrument Addendums include: • Subordination Agreement: This type of addendum outlines the priority of the security instrument in comparison to other liens or mortgages. • Assignment of Mortgage: This type of addendum assigns the right to collect payments on the loan to another party. • Waiver of Subrogation: This type of addendum waives the right of the mortgagee to seek reimbursement from another party for any losses as a result of the loan. • Power of Attorney: This type of addendum authorizes another party to act on behalf of the borrower in transactions related to the loan. Serviceer Change: This type of addendum outlines the terms and conditions of a change in the service of the loan. • Escrow Agreement: This type of addendum outlines the terms and conditions of an escrow account, if one is established.
