Kidd married his first wife, Joumana, in 1997. In January 2001, he was arrested and pleaded guilty to a domestic abuse charge for assaulting his wife Joumana. As part of his plea, Kidd was ordered to attend anger management classes for six months. Kidd completed the mandatory counseling and continued to attend on his own. He and his wife were both active in their church and were thought to have completely reconciled. The incident, however, would be considered a catalyst for the Suns to trade Kidd to the Nets that year. On January 9, 2007, Kidd filed for divorce, citing "extreme cruelty" during their relationship. He contended intense jealousy, paranoia, and the threat of "false domestic abuse claims" to the police as reasons for the divorce. On February 15, 2007, Joumana Kidd filed a counterclaim for divorce,[84] claiming that the NBA star—among countless instances of abuse—"broke her rib and damaged her hearing by smashing her head into the console of a car". The couple have three children: Trey Jason (T.J.), born October 12, 1998, and twins Miah and Jazelle, born September 26, 2001.[85][86]
On September 10, 2011, Kidd married Porschla Coleman, a former model.[87] They have two children.
On July 15, 2012, Kidd was arrested by Southampton Town police and charged with a misdemeanor of driving while intoxicated.[88] According to police, around 2 a.m. Kidd's vehicle struck a telephone pole and ended up in the woods a few blocks away from his home.[89]
