Tip: it's an inheritance limitation (4)
I believe the answer is:
tail
I believe this clue is a double definition.
'tip' is the first definition.
(thesaurus)
'an inheritance limitation' is the second definition.
(historical term for a limitation on ownership)
'it's' is the link.
(Other definitions for tail that I've seen before include "Hindmost part" , "Follow (a suspect)" , "Caudal fin" , "Animal's elongated appendage" , "Back end; follow secretly" .)
