Most spouses are embroiled in nasty divorce cases once relations have worsened beyond pair. In such situations, partners engage in several court battles with the sole purpose of retaining child custody. The child's wellbeing is the most important factor to consider, despite the constant bickering witnessed by feuding spouses. Once the dust has settled, and child custody has been awarded, parents need to develop a comprehensive plan that outlines child support mechanisms. In California, the law clearly stipulates that both parents need to be involved in the child support modification process to promote their wellbeing.
