Hello Mr. Gawinski,
First, your ex-wife's new husband's income does not come into consideration when making child support decisions. The courts have generally held that only the mother and father are expected to contribute to the support of their child.
In rare cases a stepfather who assumes a large and long-lasting role in the life of a child may be required to continue to provide support even if he were to divorce the mother, but these cases are, by far, the exception.
The idea is that this man is not the biological father and therefore should not be expected to provide financial support to the child. Exceptions occur when the stepfather adopts the child and the biological father terminates his parental rights. These situations are rare, however, as the father who terminates his parental rights loses all rights of visitation or contact permanently.
In calculating your actual income, discretionary bonuses and profit sharing plans that allow for your use of the funds are normally included.
In general, the courts will include all income including tips, commissions, interest on savings, capital gains on investments, etc. as in the case of a married couple, all of these funds would be used for the care of the household and the children. So it they are all included when calculating child support.
Please let me know if you have any other questions about this.
