This means they have the right to inherit from them with or without a Last Will and Testament.
Children are of course considered illegitimate if they are conceived and born outside a valid marriage.
But do they also have the right to inherit from the legitimate children and relatives of their parents?
If it is an intestate succession, that is, when a person dies without a will, they have no right to inherit from the legitimate children and relatives of their parents.
The legitimate children and relatives of their parents in turn also have no right to inherit from them.
This is in consonance with what is known in law as “The Iron Curtain Rule,” which bars illegitimate children from inheriting from the legitimate children and relatives of their parents and vice-versa.
It was made part of our laws in order to avoid further grounds of resentment between the legitimate and illegitimate family given the intervening antagonism and incompatibility that is presumed to exist between them.
But the rule finds no application in a testate succession, that is, when a person dies with a will.
This is so because it is based only on the presumed and not on the express will of the decedent.
Bear in mind that it is the express will of the decedent that will matter most and will be respected, if not followed, in a testate succession.
