In court filings obtained by ET dated November 30, Quaid blames "irreconcilable differences" for the pair's split, listing their date of separation as October 1, 2012. Joint legal and physical custody has been requested of the former couple's five-year-old twins Thomas Boone and Zoe Grace.

Last March, Kimberly filed for divorce explaining in court papers that the marriage had "become insupportable because of discord or conflict of personalities." A month later she withdrew the divorce papers so they could work on their marriage.

The pair married in 2004. It was the third marriage for Quaid, who was married to Meg Ryan from 1991 to 2001, and actress P.J. Soles from to 1978 to 1983.
