Can my 12 year old son be my witness in court to prove my daughters father unfit
I have a 2 month old and a 20 month old , their father has not lived with me for longer than 1 month in a stretch of 4 years. I got enough strenth to get him away from my home for good, due to his very abusive behavior. He kept me very iscolated from friends and family, so no one ever seen the things he has done or that he made me do for things like formula and diapers. My 12 year old son lives with me and knows a lot. My ex is now taking me to court with a lawyer that his parents are paying for, to try and get custody and or visitations. His parents have not wanted anything to do with my babies until now, because they don't like me. Now that we are broke up they want to be grandparents, they also have contributed to neglect and or abuse, my 15 year old son was living with me all but 1 year, can they be used as witnesses in court?
