Kimberly Buffington first filed for divorce from estranged husband Dennis Quaid in March 2012. Ironically, she withdrew the petition, only to file for legal separation in October. However, Dennis made the final move by filing for divorce on Nov. 30.

Let the Spousal Support & Custody Battle Begin

Dennis, 57, reportedly requested joint custody of the couple’s twin sons, Thomas and Zoe, both 4, and has offered to pay Kimberly spousal support, according to Radar Online.

Apparently, the couple could not officially divorce until now, because they moved to California over the summer, and the state requires a 6-month residency before someone can file for divorce — according to TMZ.

This will be Dennis’ third failed marriage.

You know the old saying “the third time’s the charm?” Apparently, that doesn’t apply to Dennis Quaid‘s marriages. His third wife Kimberly Buffington has filed for divorce, TMZ is reporting, and says their marriage “has become insupportable because of discord or conflict of personalities.”

The couple has a temporary custody plan in place for their children — twins Thomas Boone and Zoe Grace – which will grant them equal time together. While Kimberly is now in possession of the couple’s main home as well as their Mercedes, Dennis gets to keep the Escalade and a condominium they share.

UPDATE: After much back-and-forth between both parties, Dennis has filed for divorce from Kimberly.
