Chicago, Illinois Child Support Lawyer

In Illinois, child support is based upon statutory guidelines as a percentage of the payors net income, unless the court finds that application of the guidelines would be inappropriate. Child custody is always an important issue during a divorce, but it is equally important to ensure that the person with custody has the necessary financial means to provide for the child in the same manner that they were provided for during the marriage. In most cases, child support is paid by one parent to the other parent and is typically paid to the parent who has primary custody of the child.

The amount of child support is established by factors that are specified by Illinois law, along with the Illinois’ statutory “guideline” percentages of the payer’s net income. This percentage increases based on how many children need to be supported. Child support is always modifiable, upward and downward. However, modification only applies to child support payments following the filing of a petition to modify support.

In most cases, child support stops when a child turns 18 years old, but there are some exceptions to this, which include a child with a disability or a child who has not yet graduated from high school.

Divorce attorney, Martin Osinski, has vast experience in helping clients in child support matters and figuring out how much child support needs to be paid and for how long the payments will continue.
