(1) a party lacked capacity to consent to the marriage at the time the marriage was solemnized, either because of mental incapacity or infirmity or because of the influence of alcohol, drugs or other incapacitating substances, or a party was induced to enter into a marriage by force or duress or by fraud involving the essentials of marriage;

(750 ILCS 5/303) (from Ch. 40, par. 303)

(750 ILCS 5/304) (from Ch. 40, par. 304)
Sec. 304. Retroactivity. Unless the court finds, after a consideration of all relevant circumstances, including the effect of a retroactive judgment on third parties, that the interests of justice would be served by making the judgment not retroactive, it shall declare the marriage invalid as of the date of the marriage. The provisions of this Act relating to property rights of the spouses, maintenance, support of children, and allocation of parental responsibilities on dissolution of marriage are applicable to non-retroactive judgments of invalidity of marriage only.
(Source: P.A. 99-90, eff. 1-1-16.)

(750 ILCS 5/305) (from Ch. 40, par. 305)
Sec. 305. Putative Spouse.) Any person, having gone through a marriage ceremony, who has cohabited with another to whom he is not legally married in the good faith belief that he was married to that person is a putative spouse until knowledge of the fact that he is not legally married terminates his status and prevents acquisition of further rights. A putative spouse acquires the rights conferred upon a legal spouse, including the right to maintenance following termination of his status, whether or not the marriage is prohibited, under Section 212, or declared invalid, under Section 301. If there is a legal spouse or other putative spouse, rights acquired by a putative spouse do not supersede the rights of the legal spouse or those acquired by other putative spouses, but the court shall apportion property, maintenance and support rights among the claimants as appropriate in the circumstances and in the interests of justice. This Section shall not apply to common law marriages contracted in the State after June 30, 1905.

(750 ILCS 5/306) (from Ch. 40, par. 306)
Sec. 306. Commencement of Action.) Actions for declaration of invalidity of marriage shall be commenced as in other civil cases.
