Declaring a Marriage Invalid

Illinois family law attorney, declaring a marriage invalidUnder certain circumstances, an individual may wish to request that a court declare his or her marriage invalid. Invalidity of a marriage, which was formerly known as annulment, is a distinct process from divorce. In order to have a marriage declared invalid, the marriage must have occurred under specific circumstances as described by law.

Invalid Marriages

Under Illinois law, a marriage may be found invalid if it was entered into under one of the following conditions:

  1. One party did not have the ability to consent at the time of the marriage, which can occur because of a mental incapacity, or through the use of alcohol, drugs, or other substances, or because the party entered the marriage against his or her will (for example, because of the use of force);
  2. One party does not have the ability to engage in sexual intercourse due to a physical condition and, therefore, cannot consummate the marriage;
  3. One party was 16 or 17 years of age at the time of the marriage and did not have parental consent or judicial approval; or
  4. The marriage is against the law or otherwise not allowed.

Importantly, there are time limits placed on when a marriage can be declared invalid. For marriages that involve a lack of the capacity to consent, a petitioner (the person seeking the marriage to be declared invalid) has 90 days after he or she becomes aware of the described condition. For the inability to consummate the marriage, the petitioner has one year after becoming aware of the condition. For a person who married while 16 or 17, the underage party (or his or her parent or guardian) has until the time when the underage party reaches the age at which he or she could have married without needing to satisfy the requirement that was not fulfilled.

A critical issue is what happens to children that the couple had together when the marriage is declared invalid. Any children that were born or adopted during the marriage become the lawful children of the parties. Similarly, any children whose parents marry after their birth also become the lawful child of both parents.

An individual who goes through a marriage ceremony and subsequently cohabits with the person he or she married with the good faith belief that they are married becomes a putative spouse until knowledge of not being legally married terminates that status and prevents the acquisition of any further rights. A putative spouse is conferred the same rights that a legal spouse is granted, including the right to maintenance following the termination of his or her status.
