In divorces and separations, child support is always handled as a completely separate issue by the courts.
At no time is child support affected by another issue, including child custody.
Alimony and spousal support payments are also unaffected by the amount of child support or the number of children.
Alimony is usually determined by factoring in the number of years married, the income of each spouse, and their role in the marriage.
For example, one stay-at-home spouse may receive a much larger alimony payment than a spouse that has always worked.
