I gave my mom my two boys so I can try to get a better life for my boys . I moved to anther state and I'm going to school. But know she won't let me talk to the boys or know how they are she. Only has a paper that I worte can shetake away my boys from me ?

First its not a good idea to piggyback your question on someone else's. This can lead to confusion. You should start a new thread. So I've moved your question to its own thread.

One cannot just "give" children. If a court did not grant custody or guardianship, then your mom has no legal right to provide care for the children. Either you or the father should be able to take the children back at any time.
