Successor in interest: what it means

A successor in interest is, under Regulation X, a person who receives ownership of a mortgaged home from the borrower in certain cases: on the death of a joint tenant, when it passes to a relative on the borrower's death, when the borrower's spouse or children become owners, through a divorce or legal separation, or by transfer into the borrower's living trust. When the loan servicer learns of a potential successor, it must say which documents it needs to confirm that person.

In Spanish it is

Sucesor en interés (successor in interest)

Also written as: confirmed successor in interest

The full explanation

A confirmed successor in interest counts as a borrower under the mortgage servicing rules.

An example

When her mother dies, Nora inherits the house, which still has a mortgage. She writes to the loan servicer, sends the death certificate and a copy of the will, and asks to be confirmed as a successor in interest.

You will see it in…

The servicer's letter listing the documents it needs to confirm you
Mortgage statements and notices, once you are confirmed
