• Felony or Other Infamous Crime If either party are convicted of a felony during the marriage.
• Habitual Drunkenness for One Year
• Cruelty
• General Indignities These grounds are the most often cited reason for divorce. This includes such indignities to the person as shall render the spouse’s condition intolerable.
