In the papers, filed March 7, Wentz also requests both parties pay their own attorney fees, that the court’s juristiction to award spousal support is terminated and states that property rights are to be determined between the couple, who did NOT sign a pre-nup.

As RadarOnline.com previously reported Pete was ‘blindsided’ by Ashlee’s decision to file for divorce last month.

The split also came as a shock in Hollywood, where the pair were thought to have had a happy marriage. They wed at Ashlee’s parents’ Encinco home in May 2008.
