Hello everyone. I want to ask those who understand the law. My father says he will find all strong lawyers and judges, take my children from me and never show them again. He says "I don't care what you do, even if you die." And when I was still in the maternity ward and got discharged, my grandfather said "give me the girl. I want to give them proper upbringing, they need to be watched" and so on. I didn't understand, did she mean that I can't raise my own children or something?! He also says "I want them to see the world, develop and have everything" and so on. Everything revolves around money. ?
