Ruling 2761 — Inheritance (Irth)

If the deceased has full brothers and full sisters as well as paternal half-brothers and paternal half-sisters and one maternal half-brother or one maternal half-sister, the paternal half-brothers and paternal half-sisters do not inherit. In this case, the estate is divided into six parts: one part is received by the maternal half-brother or maternal half-sister, and the remainder is divided among the full brothers and full sisters, with every brother receiving twice the share of every sister.
