Child support in the United States is a legal obligation that ensures both parents contribute financially to the upbringing of their child after separation, divorce, or when parents live apart. The primary goal of USA child support law is to protect the child’s well-being by ensuring consistent financial support for essential needs such as housing, food, healthcare, education, and daily living expenses.
Child support laws vary by state, but all follow a similar principle: both parents are financially responsible for their child regardless of custody arrangements.
