Thank you for your patience. I am an attorney with many years of experience and I hope I can answer your questions
I am sorry that you are having these difficulties at such a young age. You should be enjoying yourself and your friends. I can't imagine how hard it must be without your Mom.
The laws in Colorado do not provide for a Petition for Emancipation. Emancipation is a process where you can ask the Court to give you the authority to make decisions for yourself. BUT unfortunately you don't have that option.
Colordo law DOES give your grandmother some rights to pursue visitation, but unless your Dad agrees she can not get Custody of you through the Courts.
So this means that you can only live with your Grandma IF you father allows it.
I am really sorry that I can't give you the information that you want to hear. I wish I could tell you something different bu that would be lying to you.
Your best bet is to try to get your father to at least let you spend more time with your Grandma. Perhaps if he can understand that as a young women you need the connection to another woman thta you love he will be more understanding. I hope that this is the case.
Also please know that you are growing up fast. Very soon (I know it seems like a long time now but it will pass before you know it). This means that soon you will be an adult and be able to make your own decisions.
I sincerely ***** ***** the best.
