FAQ: Does A New Spouse's Income Count Towards Child Support in Arizona?

If your ex has remarried (or you have), a question that is commonly asked is: does a new spouse’s income affect child support? In Arizona, the short answer is no.

The Rule: Applying the Arizona Child Support Guidelines

Under the Arizona Child Support Guidelines, child support is calculated based on the income of the child’s parents only. A new spouse, whether yours or your ex’s, is not a legal parent of the child and therefore their income is not included in the child support calculation.

Why Not?

Arizona law focuses on the financial responsibility of the child’s biological or adoptive parents. A stepparent has no legal duty to financially support a stepchild (absent adoption), so their earnings are not considered when determining support.

Are There Any Exceptions?

While a new spouse’s income is not directly counted, it may come up in limited ways:

• Deviation requests: In rare cases, a court may consider overall financial circumstances when deciding whether to deviate from the standard guideline amount—but even then, the spouse’s income itself is not treated as part of the parent’s income. (Everyone's case is different. To evaluate your likelihood of deviating from the guidelines, consult an attorney).

  
  

Bottom Line

Your new spouse’s income—and your ex’s new spouse’s income—does not count toward child support in Arizona. Support is based on what the child’s legal parents earn, not their new partners.
