Virginia law outlines how child support works in the state. It’s quite important that you understand your rights and obligations in this process. If you’re not sure, reach out to a Fairfax child support lawyer for clarification. The law makes it clear that both parents are obligated to provide financial support (and other forms of support) for the benefit of their child. It does not matter if the couple is married.
