B8-4-01, Riders and Addenda (06/05/2018)

There are special conditions that require modification of a security instrument (usually by a rider) or a note (usually by an addendum).

There are uniform Fannie Mae/Freddie Mac riders to security instruments, as well as some Fannie Mae-specific riders. There are also some situations in which Fannie Mae requires a rider to security instruments, but Fannie Mae has not developed a specific form.
