Dennis Quaid's wife, Kimberly Buffington-Quaid, is ending their marriage.According to court papers obtained by TMZ.com first breaking the story, Buffington-Quaid says she is filing for divorce because things have "become insupportable because of discord or conflict of personalities."
The couple, who wed in 2004, have 4-year-old, Thomas Boone and Zoe Grace together.
Born in 2007, the babies nearly died when they were given an overdose of heparin at a Cedars-Sinai Medical Center in Los Angeles. The Quaids later sued the hospital and drug manufacturer and were awarded $750,000.
A temporary custody order indicates that the couple will share custody of the twins.
Buffington-Quaid has been granted possession of the family's main house and a Mercedes, while Quaid, 57, gets a condo and a Cadillac, according to the filing. The couple will share a Range Rover.
Last October, Quaid put his 418-acre Montana property on the market for $14 million.
In a response to his wife's filing, Quaid has requested that she get nothing in their eventual settlement.
Quaid divorced Meg Ryan in 2001 and actress P.J. Soles in 1983.
