With more than 36 years of family law experience, we understand how important child support issues are for both parents and children. Our goal is to help clients achieve fair outcomes that comply with Illinois law while protecting their financial future.
Understanding Child Support in Illinois
Illinois uses an Income Shares Model when calculating child support. This approach is designed to estimate the amount parents would have spent on their children if they had remained together and then allocate that responsibility between both parents.
Several factors may influence child support calculations, including:
- Each Parent's Income
- Parenting Time Allocation
- Number of Children
- Health Insurance Costs
- Childcare Expenses
- Educational Expenses
- Special Needs Expenses
- Existing Support Obligations
Because every family's circumstances are different, child support calculations often require careful financial analysis and accurate documentation.
Establishing Child Support Orders
Whether child support is being determined as part of a divorce, legal separation, paternity case, or custody proceeding, it is important to ensure the support order accurately reflects both parents' financial circumstances.
Our attorneys assist clients with:
- Initial Child Support Determinations - We help parents establish fair child support obligations based on Illinois guidelines and relevant financial information.
- Income Verification - Accurate income reporting is essential to achieving a proper support calculation. We work to ensure all relevant sources of income are identified and considered.
Allocation of Child-Related Expenses
In addition to monthly support payments, parents may share responsibility for expenses such as:
- Health Insurance
- Uncovered Medical Costs
- Childcare
- School Expenses
- Extracurricular Activities
We help clients address these financial obligations clearly and fairly.
Child Support Modifications
Life circumstances can change significantly after a child support order is entered.
Illinois law allows child support orders to be modified when there has been a substantial change in circumstances.
Common reasons for modification include:
- Job Loss or Reduced Income - A significant decrease in earnings may justify a review of existing support obligations.
- Increased Income - Substantial increases in income may impact support calculations and lead to adjustment requests.
- Changes in Parenting Time - If parenting schedules change significantly, support obligations may need to be recalculated.
- Changes in a Child's Needs - Educational costs, medical expenses, and other financial needs may increase over time.
- New Employment Opportunities - Career advancements or employment changes may affect the financial circumstances of one or both parents.
Our attorneys help clients evaluate whether modification is appropriate and guide them through the legal process
Enforcement of Child Support Orders
When a court issues a child support order, both parents are legally required to comply with its terms.
Unfortunately, some parents fail to make required payments, creating financial hardship for both the child and the receiving parent.
We help clients enforce child support orders through legal remedies such as:
- Income Withholding Orders
- Wage Garnishment
- Contempt Proceedings
- Collection Actions
- Recovery of Past-Due Support
- Court Enforcement Motions
Our goal is to ensure children receive the support they are entitled to under the law.
Defending Against Unfair Child Support Claims
Not every support request is accurate or appropriate.
If you believe a support calculation is based on incorrect financial information or does not reflect your circumstances, our attorneys can help protect your rights.
We assist clients with:
- Reviewing Financial Disclosures
- Verifying Income Information
- Challenging Inaccurate Calculations
- Responding to Modification Requests
- Protecting Against Unreasonable Claims
A careful review of financial records is often essential to ensuring a fair outcome.
Child Support and Shared Parenting Arrangements
Many modern parenting plans involve substantial parenting time for both parents.
Because parenting schedules can significantly affect support calculations, it is important to ensure support orders accurately reflect the actual division of parenting responsibilities.
Our attorneys work closely with parents to evaluate:
- Overnight Parenting Time
- Shared Parenting Arrangements
- Transportation Costs
- Healthcare Responsibilities
- Childcare Obligations
By addressing these factors properly, we help clients pursue support arrangements that are both fair and practical.
Child Support in Paternity Cases
Child support issues frequently arise in paternity matters involving unmarried parents.
Once parentage is established, the court may enter orders regarding:
- Child Support
- Parenting Time
- Allocation of Parental Responsibilities
- Medical Expenses
- Educational Costs
We represent both mothers and fathers in paternity-related support matters and work to ensure children's needs are properly addressed.
Resolving Child Support Matters Through Negotiation
While some support disputes require court intervention, many issues can be resolved through negotiation, mediation, or collaborative family law processes.
Benefits of negotiated agreements may include:
- Reduced Conflict
- Lower Legal Costs
- Faster Resolution
- Greater Flexibility
- Improved Co-Parenting Relationships
Because our firm has Collaborative Law Training, we help clients explore practical solutions whenever possible while protecting their legal rights.
