Calculating child support payments is a critical part of any divorce, but how is this handled when there are multiple mothers? Below is essential information to know about this vital subject. Please ask our Chicago child support attorneys at Gordon & Perlut, LLC, if you have questions.
Child Support With Multiple Mothers
The child support model in Illinois was modified recently. It now follows an ‘income shares’ model that considers each parent’s income when deciding the total amount of child support. This is instead of the court ordering one parent to provide child support to the other on a mere percentage basis.
One of the reasons the state shifted in this area is the change in parental responsibility and child custody laws. Instead of giving child custody to one or both spouses and naming one as the primary custodial parent, the family court allocates the responsibilities per the Illinois Marriage and Dissolution of Marriage Act.
Illinois Courts Use The Income Shares Model To Decide Child Support With Multiple Mothers
Under state law today, all child custody cases that come from a divorce or separation require the family court to make decisions about child support. No matter if the parents are a mother and father or a same-sex couple, the court uses the income shares model to decide about child support.
Note that the income shares model is not dependent on the gender or sex of the two parents. Instead, the income shares model is utilized when two or more mothers share a child from their marriage or relationship.
What If the Parent Has Children With Separate Mothers From Different Relationships?
A situation also can arise where a parent has children with two mothers in different relationships. When the parent has a child with two separate mothers, family courts still utilize the income shares model to arrive at the proper child support obligation. However, the court will combine the net incomes of both parents instead of their gross incomes.
To decide the net income for the parent with a child with two separate mothers, the family court deducts the child support amount the parent currently pays for the child shared with the first mother. Next, the total amount of child support for the child shared with the second mother is based on all parents’ net income minus the current child support payment.
Statistics On Child Support With Multiple Mothers
Navigating child support obligations with multiple mothers presents a complex legal and financial landscape, especially as family structures continue to evolve. In the United States, an increasing number of noncustodial fathers have children with more than one mother, creating layered responsibilities across households. Understanding the statistics and legal frameworks surrounding this issue is essential for policymakers, legal professionals, and families alike.
National Child Support Overview
According to the U.S. Census Bureau,
over 21.9 million children had a parent living outside their household in 2018, representing more than one in four children under 21. Of these children, approximately 30.1% lived in poverty, nearly three times the rate of children in two-parent households. Child support is a critical financial lifeline for many custodial parents, particularly single mothers, who disproportionately bear the economic burden of raising children.
Legal Complexities of Supporting Multiple Mothers
When a father has children with more than one mother, courts must allocate child support fairly across households. This is typically done using a prorated method, where the total support obligation is divided based on the number of children and their individual needs. Courts assess the noncustodial parent’s gross income, including wages, bonuses, and other sources, and may impute income if the parent is unemployed or underemployed.
Each state has its own guidelines, but most follow a formula that considers existing support orders before issuing new ones. For example, if a father already pays support for two children from one relationship, that obligation is factored into the calculation for a third child from another relationship. This approach ensures that no child is unfairly disadvantaged, although it can result in lower payments per child as obligations increase.
Impact on Families and Children
The financial strain of supporting multiple households can be substantial. Fathers with limited income may struggle to meet all obligations, leading to arrears, enforcement actions, or even incarceration in extreme cases. Meanwhile, custodial mothers may receive inconsistent or insufficient support, affecting their ability to provide stable housing, nutrition, and education for their children.
Children in these situations often experience economic instability, which research links to poorer health outcomes, lower academic achievement, and increased interaction with the child welfare system. The ripple effects can extend into adulthood, influencing employment prospects and long-term well-being.
Policy Considerations
As family dynamics shift, legal systems must adapt to ensure equitable outcomes. Some experts advocate for standardized national guidelines to reduce disparities across states. Others suggest reforms that emphasize shared parenting responsibilities, not just financial contributions. Ultimately, child support involving multiple mothers is not just a legal matter—it’s a social one. Ensuring that every child receives adequate support, regardless of family structure, is vital for promoting fairness, stability, and opportunity.
