unrightful

Lacking legal claim

Unrightful means not legitimate, just, or lawful—lacking proper authority or entitlement: an unrightful claim to the throne, unrightful possession of the property.

The word is somewhat formal and appears most often in legal or political contexts where questions of legitimacy arise.
