How is child support determined in Illinois?
Child support in Illinois is primarily calculated using a formula based on the income of both parents. The amount of support is determined by the combined income of both parents and the number of children they have. The Illinois Department of Healthcare and Family Services provides specific guidelines, which include a percentage of combined parental income assigned for child support based on the number of children. Factors such as additional medical costs, child care, and extracurricular activities may also affect the final amount. If the parents have significant income differences or if there are special needs for the child, the court may adjust the standard guidelines. The goal is always to ensure that the child’s needs are met, and the financial responsibilities are fairly shared.
Can I modify my divorce or custody agreement in the future?
Yes, it is possible to modify your divorce or custody agreement, but it requires showing a significant change in circumstances. In Illinois, both child custody (parenting time and decision-making) and child support arrangements can be modified if there is a material change in circumstances that justifies the change. For example, a parent may want to modify the parenting plan if they have a significant change in their work schedule, if the child’s needs change, or if there is a move out of state. Similarly, if the financial situation of either parent changes, it could affect child support obligations.
To modify an order, you must file a petition with the court, and the judge will review the case to determine whether the requested changes are in the best interests of the child.
How long does the divorce process take in Illinois?
It depends on several factors. The fastest route is an uncontested divorce, where both spouses agree or work to agree on all key issues—property division, spousal support, parenting, etc. In those cases, the process can take as little as 2–3 months, especially if all paperwork is in order.
A contested divorce, where there are disagreements that need to be resolved through negotiation, mediation, or litigation, will take longer—often 6 months to over a year. The timeline can vary based on:
- How complex your financial situation is
- Whether there are disputes over parenting or support
- The level of cooperation between you and your spouse
- The court’s current caseload and availability
Even in contested cases, working with an experienced attorney can often help move things forward more efficiently by narrowing the issues and staying organized.
How is child custody determined in Illinois?
In Illinois, child custody is legally referred to as the “allocation of parental responsibilities.” This includes two main parts: decision-making authority (who makes major choices about the child’s education, healthcare, religion, etc.) and parenting time (where the child lives and how time is split between parents).
The court decides custody based on what’s in the child’s best interests. That includes looking at factors like:
- Each parent’s involvement in the child’s life up to now
- The ability of the parents to cooperate
- The child’s relationship with each parent
- Any history of violence or substance abuse
- The child’s preferences, depending on age and maturity
There is no automatic assumption that the mother or father will get more time; the court’s goal is to create an arrangement that supports the child’s emotional, physical, and developmental needs.
What is a parenting plan, and do I need one?
Yes. If you have children and are getting divorced in Illinois, you are legally required to submit a parenting plan. This document lays out how you and your co-parent will handle parenting time and decision-making after the divorce is finalized.
A parenting plan must cover:
- Who will make major decisions for the child
- A detailed schedule for parenting time (weekdays, weekends, holidays, vacations)
- How future disagreements will be resolved
- Transportation arrangements and communication guidelines
If both parents agree on everything, they can submit one joint plan. If not, each parent submits their own version, and the court decides. Having a detailed plan in place helps prevent confusion and conflict down the road—and keeps both parents aligned around what’s best for the child.
