Child support payments are primarily intended to cover the basic living expenses of the child, including food, clothing, and housing. However, depending on the jurisdiction and the specifics of the child support agreement or court order, child support may also be used to cover additional expenses such as education and extracurricular activities. These expenses are often considered on a case-by-case basis, and parents may need to agree on sharing these costs or seek a modification of the child support order to specifically address them. It's important to consult with a legal professional to understand how these expenses are handled in your case and jurisdiction.
