HUSBAND and WIFE have a child, SON. SON is 30 years old but he still lives with his parents. SON is jobless and lazy so the couple sued him for unlawful detainer in order to eject him from the premises of their home. They argue that their son is old enough to be evicted and he should find his own house. Will the action for unlawful detainer prosper?
