Marriage laws vary by state, but all states prohibit some kinds of marriages. Some people start the divorce process only to find out that their marriage is actually invalid. Conversely, a couple may want to marry but later find out that they cannot. It is important to understand the laws in Illinois and what marriages are prohibited.
Invalidity and Prohibition
In Illinois, marriages that are not permitted are termed invalid. In order for a marriage to be declared invalid, Illinois law allows certain people to file a petition for a Declaration of Invalidity of Marriage. Depending on the circumstances, certain aspects of the marriage may still apply.
