I travel often for work and my daughter is starting school. We have determined that it would better for her to move with my parents in Rochester, NY. In order for her to register to the schools in NY state I must provide proof that I am giving legal guardianship to my parents. How do I do that, and in which state do I file the papers. She was born in NY and our permanent residence is MD. Also, her father is not on the birth certificate and plays no role in her life.
