SERVITUS TIGNI IMMITTENDI, civil law. The name of a servitude which consists 
in requiring him who owes it, to permit his neighbor to place his joists on 
his wall. It differs from the servitude Oneris ferendi. (q.v.) in this, that 
in the former the owner of the servient building is bound to repair and 
rebuild the wall; whereas, in the latter he is not. Dig. lib. 8, Sec. 2.
