Los Angeles, CA family law attorney Robyn Santucci talks about whether or not you will continue paying child support after your ex remarries. If an ex-spouse remarries, it is unlikely that child support will be affected. Child support is determined by the child’s needs and is based on the income of both parents, as well as the time each parent spends with the child. Consequently, factors such as the remarriage of either parent are not significant in calculating child support.
