An adjustable latch assembly used in a lever lock comprises a shell, a shelf, a rotator, an actuating arm, a positioning and pulling assembly, and a bolt. The shell is attachable to a door. The shelf has a first position and a second position within the shell. The rotator is mountable on the shelf. The actuating arm co-operates with the rotator, so as to be actuated by the rotator when the rotator rotates. The positioning and pulling assembly positions the shelf in the first position or the second position and pulls the bolt inward. The adjustable latch assembly has a first backset when the shelf is at the first position and a second backset when shelf is at a second position.
