II. Dr. Lopez, a 70-year old widower, and his son Roberto both died in a fire that gutted their home while they were sleeping in their air-conditioned rooms. Roberto’s wife, Marilyn, and their two children were spared because they were in the province at the time. Dr. Lopez left an estate worth P20M and a life insurance policy in the amount of P1M with his three children --- one of whom is Roberto --- as beneficiaries. Marilyn is now claiming for herself and her children her husband’s share in the estate left by Dr. Lopez, and her husband’s share in the proceeds of Dr. Lopez’s life insurance policy. Rule on the validity of Marilyn’s claims with reasons. (4%)
