Spouses pay alimony, or spousal support, only when one spouse can show a need for financial help. You're always free to work out an agreement with your co-parent about child support. Learn about the types of alimony available in Virginia, how it's calculated, and the factors courts consider when awarding spousal support. You can seek a child support order for any and all children who live with you, whether you are married or unmarried. Alimony, also called "maintenance" or "support," is financial support paid by, or to, your spouse. In Virginia, child support obligations normally last until the child turns 19-years-old, but can continue past that age if the child is still in high school. A person making qualified alimony payments can deduct them.
