Illinois Joint Simplified Dissolution of Marriage (SD) is a type of divorce available to couples who meet certain eligibility requirements. It is a short and simplified process that is faster and less expensive than a traditional divorce. Couples must meet the following requirements to be eligible for a SD: both parties must agree to the divorce, both parties must consent to the simplified dissolution process, both parties must have lived in Illinois for at least 90 days and must agree to the division of marital property and debts, and both parties must have a valid marriage license. There are two types of SD available in Illinois: Regular SD and Express SD. Regular SD is the standard process, which begins with the filing of a joint petition, and requires a court hearing. Express SD is a faster process, which requires the filing of an express petition and a simplified hearing. Both types of SD allow couples to resolve their issues without the need for a trial.
