What principle underlies the legal duties of both parents concerning child support?

The principle underlying the legal duties of both parents concerning child support is primarily centered around the financial ability of the parents and the needs of the child. This principle acknowledges that both parents have a legal obligation to contribute financially to the upbringing of their child, ensuring that the child's needs are met regardless of the parents' relationship status or living arrangements.

In family law, courts assess the financial capabilities of each parent, including income and resources, alongside the specific needs of the child, which can include basic necessities such as food, clothing, education, and healthcare. This evaluation aims to strike a fair balance that supports the child's welfare while also taking into consideration the parents' financial situations.

This framework is designed to promote the child's best interests, ensuring that they receive the support needed to thrive. It moves beyond emotional attachments or the extent of time spent with the child, focusing instead on the practical and financial roles that each parent plays in supporting their child.
