Truancy and child support are two separate issues. You must continue to pay child support, however you can file for custody modification either by seeking custody or increasing custody, thus reducing your child support obligation, if you can prove the mother is not acting in the best interests of the child by enabling his or he truancy.
A person who wags school is often referred to as a truant.
Truancy refers to a student's deliberate absence from school without a valid excuse. From an educational point of view, truancy can negatively impact a student's academic performance, social development, and overall success in school. It is a concern for educators as it can lead to missed learning opportunities and disengagement from the educational process.
