Bon Jovi guitarist Richie Sambora is calling for a pre-nuptial agreement, signed the day before he wed Heather Locklear 11 years ago, to be considered as he battles his divorce. The rocker has filed new court papers as divorce proceedings heat up, insisting the pre-nup be "enforced."

In addition, the rocker insists that he and Locklear share joint custody of their eight-year-old daughter Ava. Locklear is seeking sole physical custody.

In the papers, filed in Los Angeles Superior Court last week and obtained by TV show “Extra,” Sambora also lists December 26 as the official separation date.
