Actor Dennis Quaid is steeling himself for a divorce battle after his wife filed documents to end their marriage.

The Day After Tomorrow star Quaid's third wife, Kimberly Buffington-Quaid, has filed for divorce and is demanding spousal support, her lawyers' fees, and a share of the actor's assets.

However, the split could be a drawn-out affair as Quaid wants Kimberly to get "nothing," according to TMZ.com.

In her divorce petition, Kimberly's representatives state, "The marriage has become insupportable because of discord or conflict of personalities... that destroys the legitimate ends of the marriage relationship and prevents any reasonable expectation of reconciliation."

Editors at the website report Quaid is resisting Kimberly's demands for regular payments and a fair division of the couple's assets.

A temporary order has been put in place giving the couple joint custody of its four-year-old twins.

Quaid and Kimberly wed in 2004. He was previously married to actresses Meg Ryan and P.J. Soles. Both unions ended in divorce.
