Illinois Divorce Details

Use DivorceWriter to complete your own Illinois divorce forms. You'll receive all documents you need to get a divorce in Illinois, ready-to-file, with complete filing instructions. Division of property, debts, alimony, name change, and minor children (including parenting time, Illinois child support calculations, and more) are covered in the DivorceWriter interview and documents.

State Residency Requirement

To file for divorce in Illinois, at least one spouse must be a resident of the state (or stationed in-state while a member of the armed services) for at least 90 days before filing.

Grounds for Divorce

While Illinois has several fault grounds for divorce, the vast majority of divorces in the state are filed on no-fault grounds. If you and your spouse have "irreconcilable differences" that have permanently damaged your marriage, you have met the grounds for no-fault divorce in Illinois.

Time to Complete

Uncontested divorces in Illinois are usually finalized 30-60 days after filing.

Types of Divorce in Illinois

Illinois has two divorce options--simplified and standard. Everyone is eligible for a standard divorce, but you have to qualify for a simplified divorce. The cost and time to complete both types are the same. DivorceWriter makes it easy to choose the right divorce type for you, and if you change your mind at any point, you can switch your paperwork at no additional charge.

Child Support

As of July 1, 2017, the standard child support calculation in Illinois is no longer based on a flat percentage of net income. Instead, the income shares model, which is used in most states, has replaced the flat percentage child support calculation. The income shares model starts by determining the basic child support obligation, which is the total value of child support owed to the children by both parents together. Then, each parent is assessed a portion of the basic support obligation, which is proportionally based on that parent's contribution to the total household net income. The income shares model also takes into account additional expenses and the amount of parenting time each parent has with the children to arrive at the final support obligation for the payor parent. Of course, after seeing the support calculations using the new income shares model, the parents can enter a different amount, if desired.

If you have agreed to a different child support amount than the one calculated under the Illinois Child Support Guidelines, the DivorceWriter interview makes it easy to select your chosen support amount instead.
