Dissomaster and the California Guideline Child Support Calculator [as well as any of the other certified calculators that exist in the market] are merely tools for the application of the guideline formula contained in the California Family Code. Child support is based on the relative income of the parents as well as the amount of time each parent has physical custody of the child. Each parent has an obligation to support the child and the mere fact that the custodial parent is able to provide a higher standard of living then the non-custodial parent is not a valid consideration in setting what that support obligation should be. Any claim that the custodial parent does not need your contribution will most likely fall on deaf ears as the Court will rightly point out that you have both a legal and moral duty to contribute to the support of your child and the relative wealth of the other parent does not obviate you obligation.
