Heather Locklear's estranged husband, rocker Richie Sambora, is asking that the prenuptial agreement signed by the couple before they were married in 1994 be "enforced," according to legal papers filed last Friday in Los Angeles Superior Court.
In his filing, Sambora, the guitarist for Bon Jovi, seeks joint custody of the couple's 8-year-old daughter, Ava Elizabeth. He also requests that he not be required to pay spousal support. His papers list the couple's separation date – Dec. 26, 2005 – the first time that the day has actually been revealed.
Last Feb. 2, the same day divorce papers were filed, Locklear's rep told PEOPLE: "After 11 years of marriage Heather Locklear has filed for divorce from Richie Sambora. … This is a private matter and there will be no further comment at this time."
In the filing, Locklear alone requested physical custody of daughter Ava, with visitation rights for Sambora. The actress cited "irreconcilable differences" as the reason for the split. The divorce petition also cited a prenuptial agreement for determining how their assets would be divided.
The couple became engaged seven months after they met through a friend.
The day after Sambora's proposal, Locklear, who was then starring on Melrose Place, proudly flashed her pear-shaped diamond engagement ring from Cartier while attending the Emmys. They soon set up house in Locklear's airy, four-bedroom home in L.A.
This was the second marriage for Locklear, 44, who split from Motley Crue drummer Tommy Lee in 1993 after nearly eight years of marriage. This was the first marriage for Sambora, 46, who previously dated Cher.
Locklear's TV credits include Spin City, Dynasty and T.J. Hooker. She recently starred opposite Hilary Duff in The Perfect Man.
