No, a new spouse of a payor is not responsible for making support payments. And usually the income and assets of a new spouse (of either a payor or a recipient) aren’t considered when child support amounts are being worked out.
The amount of child support is based on:
- how much the payor earns,
- how many children they have to support, and
- where they live.
If one parent makes a claim of undue hardship, each parent's household income is considered. That includes the incomes of new spouses. But that still doesn't mean that a payor's or recipient’s new spouse becomes responsible for making child support payments. See Child support for more information about this.
If a child's parent separates from their new spouse, the new spouse might have to pay child support if they're considered to be a step-parent to the children under the BC Family Law Act. See Step-parents' rights and responsibilities for more about this.
