I often receive questions from people about unpaid child support. Can I still collect on unpaid child support? Does interest accrue on unpaid child support? The answers to both of these questions are yes.
California law provides that a child support judgment is enforceable until paid in full or otherwise satisfied — even after the child reaches age 18. This includes interest and penalties computed thereon. (California Family Code Sections 291(a) and 4503). See also Marriage of Hamer (2000) 81CA4th 712, 718, 97 CR2d 195, 199.
