Nevada ? Nevada Gov. Jim Gibbons filed Friday for a divorce from his wife, Dawn, and asked for a court order to determine whether the governor or first lady will live at the governor’s mansion.

A complaint filed in Carson City District Court by Gibbons’ lawyer, Gary Silverman, lists incompatibility as grounds for ending the couple’s marriage of more than 21 years.

Silverman also said he’s seeking “a court ruling concerning the living arrangements” at the mansion in Carson City. Dawn Gibbons is staying at the taxpayer-supported mansion while the 63-year-old governor lives in their home in Reno.

The complaint is the latest development in a series of difficulties for Gibbons – including a still-pending corruption investigation by the FBI and claims by a Las Vegas cocktail waitress that he assaulted her in a parking garage after she rebuffed his advances just before his 2006 election. Police later said they found insufficient evidence to support the woman’s claim.
