Hi all just looking for some advice please. My child was picked up by his grandparent ready for his weekend access to his father. His father has now decided to keep him and won't return him back home. His father has PR but child has lived with me full time for the last 4 years since our relationship breakdown. He has my child every other weekend normally but he has now decided to keep him and has changed his schooling without my permission. Can he legally do this and what can I do to get my child back please.
