Will my child support obligation go down if my ex-wife gets remarried?
While I am not licensed to practice law in your state and am unable to give you legal advice, I can give you some general observations on this issue based on the jurisdiction where I practice.
Where I do practice in Virginia, child support is based on the relative income of the parents. This does not included their spouses. So, if the party who receives child support marries a very wealthy individual, it will not lower the amount of child support to be paid.
There are ways to modify child support if you can prove that there has been a substantial and material change. That would include changes to income and changes in the amount of time that the child spends with the non-custodial parent.
Child support is very jurisdiction-specific and requires a specialized knowledge of local law. For these reasons I would suggest you contact an attorney who specializes in family law matters in your jurisdiction.
Remember, I am unable to provide you with anything more than tips on these matters, so please contact an attorney in your jurisdiction to obtain specific advice as to the laws of your state and how they impact your case.
