Acceptance may be express or tacit.
An express acceptance must be made in a public or private document.
A tacit acceptance is one resulting from acts by which the intention to accept is necessarily implied, or which one would have no right to do except in the capacity of an heir.
Acts of mere preservation or provisional administration do not imply an acceptance of the inheritance if, through such acts, the title or capacity of an heir has not been assumed. (999a)
