385. In respect to a right, such as right of usufruct, the duration of existence of which is uncertain, such portion as can be bequeathed is determined by appreciating the value such right has at the time of succession.
Where the value of such right exceeds the portion which can be bequeathed, the heir can either carry out the legacy of the ancestor or retake such right by giving the entire right of ownership of such portion as can be bequeathed.
