FF to today, they're having issues regarding child support. Both of them are working and the kids are now 7 and 5 years old. Wala silang napagusapan na exact amount para sa suporta dun sa bunso pero pag may kailangan, gaya ng pampagamot or tuition, nagbibigay ang Kuya ko basta itinawag nung wife nya. But recently, they're having issues kasi parang ang gusto nung babae, sagutin ng Kuya ko lahat ng expenses nung bata, halos literal na lahat. We don't really understand the law that's why we wanted to ask here. Also, if my brother's to file an adultery/annulment case and seek child custody, what are the chances that he'll win?
