Shared gifts follow the rules for gifts inter vivos in all matters relating to imputation, calculation of the reserve and reduction.
The action for reduction may only be brought after the death of the disposant who made the sharing. In the case of a shared gift made jointly by the two spouses, the action for reduction may only be brought after the death of the surviving of the disposants, except in the case of a non-common child who may bring the action as soon as his or her author dies. The action is time-barred five years after the death.
The presumptive heir not yet conceived at the time of the shared gift has a similar action to make up or complete his share of the inheritance.
