My question involves a child custody case from the State of: FLORIDA.
I'm not the biological father but i signed the birth certificate 8yrs ago and have been in the child's life ever since. We split 7yrs ago. She tried to put me on child support about 4 yrs ago but I fought it and won. Because I told the judge that I didn't want to be on child support if I have already been taking care of the child financially. I asked for a DNA test and told the judge that i would continue to take care of the child regardless of the DNA results. The judge granted me a DNA test which came back as the child not being mine. She's is married now and i have been unemployed for a year and a half and I'm in school full time to get myself together to better myself so i can provide better for my child.I'm married now. But normally if I don't get the child on thanksgiving i get the child on Christmas. Well when I picked the child up we verbally agreed for me to bring the child back Tuesday after Christmas.She demanded she was gonna pick him up Christmas (Saturday) in which i refused to let her get him because of our verbal agreement. She threatened to call the police on me if i didn't bring the child to her. I then called and consulted with a police officer friend of mines. He informed me that there was nothing she could do about the issue. She called the police on me and they told her they could do nothing about the issue . Now that I have returned the child on the agreed upon verbal date, she say's she will not let me see the child unless I have a court order. I she tries to control me and what I do by always threatening to not let me see the child who is now 8yrs old he calls me Dad because I'm all he knows.
My questions are:
Do I have any legal rights to file for joint custody?
IF I do have rights, with me filing for joint custody can she try to come after me for child support again?
Will I have to pay child support if a judge has already ruled I didn't have to pay child support?
