I am a mother of 2 girls ages 3 and 2 and about a year ago their father and I split up. I still let him see the girls but one day he decided not to bring them back to me and falsly accused me of beating them ( which I have proof I didn't. He even sent me several text messages saying I never hurt them in any way) and child services has since been involved. I personally feel like the only reason he wants them is for the government assistance money seeing as how the next day he went and applied for it with their names on it. I go visit them as much as I can but I would like to have the child services case closed and have at least half custody. How hard would it be for me to obtain custody and bring them to PR after so long and how would I go about this seeing as how I currently live in Puerto Rico and am in college here? Any advice is greatly appreciated. Thank you.

As soon as you split you should have filed for custody. Now its going to be much harder. You need an attorney.
