Upon death, succession is initiated.
At this point, on the one hand, the effects retroactively transferring inheritance rights take place, and on the other, the moment is identified from which the statutory deadlines begin for completing the various formalities prescribed by the Civil Code and tax laws.
There are two types of succession: intestate succession (without a will) and testamentary succession (with a will).
Intestate succession occurs only if the deceased did not make a valid will or, even if a will was made, if it did not cover the entire estate.
Within this framework lies the so-called necessary succession, which does not represent an additional or distinct method for the deceased to dispose of their property. Rather, it identifies a specific legal regime designed to protect certain categories of individuals, known as heirs with a reserved portion—namely, the spouse, children, and legitimate ascendants—by granting them a predetermined share of the estate or other rights in the succession.
