After my partner's death, how long do I have to file for succession?

There is no time limit established by law for the succession to be carried out. However, it is suggested to do it as soon as possible in order to avoid difficulties in relation to the administration of the assets and the possibility of one or more of the heirs taking possession of the assets. 

Note: In the case of couples in common-law marital union (UMH), the process of declaring the UMH and/or liquidation of the patrimonial partnership must be initiated in the year following the death of the partner. Although there is no time limit for initiating the succession, in the case of the UMH there is one (1) year to claim the right to the 50% of the patrimonial partnership.
