Many people believe that once the judge signs a divorce decree or parentage order, the legal battle is over. Unfortunately, real life rarely stays frozen in time. Jobs change, parents relocate, children grow, and sometimes one party simply stops following the court’s orders. When that happens, former spouses and co-parents often find themselves back in court.
This process is known as post-judgment litigation, and it is one of the most common reasons people hire a family law attorney years after their divorce or parentage case has ended.
If you live in Cook County, DuPage County, or Lake County, understanding how post-judgment litigation works in Illinois can help you protect your rights and your family.
What Is Post-Judgment Litigation in Illinois?
Post-judgment litigation refers to any legal action filed after the court has already entered a final judgment. In a divorce or parentage case, the judgment might include orders related to:
- Parenting time and decision-making
- Child support
- Spousal maintenance (alimony)
- Division of property
- Enforcement of court orders
When circumstances change or one party fails to comply with the judgment, either party may file motions asking the court to modify, enforce, or clarify the existing order.
Illinois courts recognize that families evolve, and the law provides several mechanisms to address those changes.
Below are five of the most common types of post-judgment litigation in Illinois family law cases.
1. Modification of Parenting Time or Parental Responsibilities
Parenting plans are designed to reflect the child’s best interests at the time the Allocation Judgment is entered in a divorce or parentage case. However, life circumstances can change dramatically, making the original parenting time schedule or allocation of parental responsibilities no longer workable.
Generally, under Illinois law, a parent may seek a modification of parenting time or decision-making responsibilities when there has been a substantial change in circumstances and the modification is in the child’s best interests.
Examples include:
- One parent relocates to another city or state
- A parent’s work schedule changes significantly
- The child’s needs change as they grow older
For example, a parent who now works night shifts may seek to modify the parenting schedule to ensure the child is cared for appropriately during those hours.
There are other factors and timing requirements to consider, so it is important that you consult experienced family law attorneys about modifying your Allocation Judgment.
2. Child Support Modification
Child support orders are based on the Illinois income-shares model, which considers both parents’ incomes and the amount of parenting time each parent exercises.
If a parent experiences a significant change in financial circumstances, the court may modify the child support order.
Common reasons for modification include:
- Job loss or substantial decrease in income
- A significant increase in one parent’s income
- Changes in the child’s expenses
- A shift in parenting time
For instance, if a parent receives a major promotion that substantially increases their income, the other parent may petition the court for a modification of child support to reflect the new financial reality.
3. Enforcement and Contempt Actions
Unfortunately, not everyone follows court orders. When a party refuses or fails to comply with the terms of the divorce judgment, the other party can ask the court to enforce the order.
This is typically done through a Petition for Rule to Show Cause, which asks the court to find the non-complying party in contempt of court.
Examples include:
- Failure to pay child support
- Refusing to follow the parenting schedule
- Not transferring property awarded in the divorce
- Ignoring maintenance obligations
If the court finds the party in contempt for willful disregard of its orders, the judge can impose penalties such as fines, attorney’s fees, or even jail time until compliance occurs.
4. Relocation Cases
When a parent wants to move with a child outside certain geographic limits, Illinois law requires court approval or the other parent’s consent.
Relocation disputes arise when a parent wants to move:
- More than 25 miles from the child’s current home in one of the “collar counties” such as Cook, DuPage, or Lake County
- More than 50 miles in other counties in Illinois
- Out of state entirely if it is more than 25 miles
If the other parent objects, the court will evaluate whether the relocation is in the best interests of the child.
For example, if a parent is offered a new job in California and wants to move there with their child, they will need to file a relocation petition and demonstrate how the move benefits the child if the other parent does not consent to the move.
5. Maintenance (Alimony) Modification or Termination
A court may modify maintenance when there has been a substantial change in financial circumstances, such as:
- Sudden unemployment
- A major increase in income
- Retirement
For instance, if the former spouse paying maintenance is laid off from their job, they could seek to modify maintenance to reflect their new income. This may result in a lower maintenance payment or maintenance may stop until the paying spouse gets a new job or a new motion to modify is adjudicated.
Additionally, under Illinois law, maintenance may be terminated if specific statutory triggers occur, including the remarriage of the receiving party, or if that party is engaged in a resident, continuing conjugal relationship—commonly referred to as cohabitation.
For example, if a maintenance recipient moves in with a new partner and begins sharing expenses and daily life in a marriage-like relationship, the paying spouse may file a petition to terminate maintenance.
Because these cases are highly fact-intensive and often contested, strong legal representation is essential to gather evidence, present a compelling case, and protect your financial interests.
