My question involves a marriage in the state of: California

I'm separated and we are divorcing. I have many items at my old home (furniture, clothes, family memorabilia, etc.) that are clearly NOT community property. My wife refuses me access to the property to get some of the things, even under supervision. The locks have been changed. The value of the items is not large, only to me. How can I recover my stuff quickly? Can I file an "order to show cause" and force her to appear in Court to explain her refusal / actions?

Thanks
