6. Conjugal or exclusive property

In 1970, Bob and Issa got married without executing a marriage settlement. In 1975, Bob inherited from his father a residential lot upon which, in 1981, he constructed a two-room bungalow with savings from his own earnings. At that time, the lot was worth P800, 000.00 while the house, when finished cost P600, 000.00. In 1989, Bob died, survived only by his wife, Issa and his mother, Sofia. Assuming that the relative values of both assets remained at the same proportion:

1. State whether Sofia can rightfully claim that the house and lot are not conjugal but exclusive property of her deceased son. [3%]

2. Will your answer be the same if Bob died before August 3, 1988? [2%]
