Do step-parents pay support?
Although parents have the primary responsibility to pay child support, other guardians and step-parents may be responsible for paying child support.
A step-parent’s duty to pay child support is secondary to that of a parent or guardian. As well, it is limited by consideration of how long the step-parent lived with the child and the standard of living the child had during the relationship between the step-parent and parent.
A step-parent may be responsible for child support if they have lived with and contributed to the support of the child for at least one year.
