I was awarded full, sole custody of my grandson in Sept. 2011. He is 3yrs. old now. Both the mother (my daughter, lives in Annandale, va) and father (who lives in s. Carolina) continue to have drug problems. Because custody is "temporary" they may file a petition with the court to regain custody when they feel the are able to take care of him. My husband and I plan to move to Florida in 3-5 yrs. We live in Gainesville, VA. Are we able legally to move with our grandson?
