Los Angeles, CA family law attorney Robyn Santucci talks about whether or not you will continue paying child support after your ex remarries. She mentions that if an ex-spouse remarries, child support is unlikely to be affected. Child support is determined based on the needs of the child, the income of both parents, and the amount of time each parent spends with the child. These are the primary factors used in calculating support. Whether either parent remarries generally has no impact on the child support obligation.
