The heir has means to claim any part of the estate from whoever has it because they are the heir.
Although it seems obvious that such property must be returned to the heir, the law provides for the acquisition of property through usucaption, that is, without having any title, that property or properties have been possessed for a legally determined long time, uninterruptedly and peacefully.
The Department of Proceedings of GABARRÓ ADVOCATS –HERÈNCIES- defends heirs who claim a property of the inheritance or, conversely, the right of the holders of property who consider it to be theirs and therefore need not return it to the heir.
