Judgment in Ejectment Binding only on Parties

A judgment directing a party to deliver possession of a property to another is in personam. x x x Any judgment therein is binding only upon the parties properly impleaded and duly heard or given an opportunity to be heard. However, this rule admits of the exception, such that even a non-party may be bound by the judgment in an ejectment suit where he is any of the following: (a) trespasser, squatter or agent of the defendant fraudulently occupying the property to frustrate the judgment; (b) guest or occupant of the premises with the permission of the defendant; (c) transferee pendente lite; (d) sublessee; (e) co-lessee; or (f) member of the family, relative or privy of the defendant.
