In Spain, under Regulation (EU) No 650/2012, when planning an international or cross-border succession, consideration should be given to the possibility of choosing the law applicable to the succession, a choice known as professio iuris.
The choice may only be made in favour of the law of the State whose nationality the person making the choice possesses, either at the time of making the choice or at the time of death.
Where a person has more than one nationality, he or she may choose the law of any of the States whose nationality he or she possesses at the time of making the choice or at the time of death.
The choice must be made expressly in a declaration in the form of a disposition of property upon death or be demonstrated by the terms of such a disposition.
