Peter had been paying child maintenance towards a child who was believed to be his. He has paid the maintenance for 11 years without a maintenance order in place. He just supported the child under the impression that he was the father. After a paternity test, Peter discovered that he is not the biological father of the child and now wants to claim all the child maintenance money back from the mother of the child.
Can Peter legally claim back the child maintenance, and if so, who can he claim the child maintenance from?
