Article 890

The legitime reserved for the legitimate parents shall be divided between them equally; if one of the parents should have died, the whole shall pass to the survivor.

If the testator leaves neither father nor mother, but is survived by ascendants of equal degree of the paternal and maternal lines, the legitime shall be divided equally between both lines. If the ascendants should be of different degrees, it shall pertain entirely to the ones nearest in degree of either line. (810)
