I would like to ask regarding my mom in-law's situation. She passed away days ago, and ever since i and my husband got married i have known their family situation that their dad never supported them-his mom, and his two siblings, whether financially or even his presence in important matters. Their dad has been living with different women for the past 18 years, and now that their mom died, he wanted that all their properties (house, money,etc) would go to him and his present "querida". Do my husband and his siblings have the right to own the house? and what lawsuit/s can be filed against their dad, aside from having queridas? what articles and sections of the Philippine Constitution did their dad violate?
