Good day, I would like to have an advice, my parents separated for years. My father have another family now and have 2 children. The problem is my father doesn't support us financially even though were the legal children. Please help us. Thank you.

Your mother needs to go to court for child support. She should have done that when they first divorced.

How old are you and your siblings? Are the 2 children in his other family step children?

Are the other two children step children? Or are they biologically his as well? I have to ask because it makes a huge difference. How old are you and your siblings? This also makes a huge difference in whether he would be ordered to pay child support. Also, what is your general location? We don't need your exact address but state or country if not in the U.S.
