Both parents are responsible for contributing to a child’s living costs, even if one doesn’t have any contact with the child.
Child contact arrangements are treated as a completely separate matter from child maintenance, which is usually dealt with by the Child Maintenance Service rather than the courts.
You can, if it’s safe and appropriate, come to an agreement with the other parent about how much they pay and when.
However, if you’re leaving an abusive relationship, you may not want to be in touch with the other parent.
Instead, you can use the Child Maintenance Service, which will make the necessary arrangements for you.
