Bill > HB1874

This bill proposes to add a new legal provision to Missouri state law that allows individuals to sue third parties for "alienation of affection," which is a legal term describing actions that intentionally interfere with or damage a marriage by disrupting the relationship between spouses. Specifically, the bill enables a person to bring a civil lawsuit against a third party who is believed to have negatively impacted their marital relationship, with potential monetary damages to be determined by the court. The bill includes two key limitations: first, such a lawsuit must be filed within three years of the last act that caused the alleged harm, and second, the lawsuit can only be brought against an individual person (not a corporation or other legal entity). This type of legal action is relatively rare in modern times and is only recognized in a few states, typically allowing a spouse to sue someone they believe has intentionally and wrongfully interfered with their marriage, such as by having an affair with their spouse.
