Husband claimed he filed Divorce Papers

You should check with the office of the clerk of the court in your county. The filing would be public record.

I agree with my colleague.  You need to check with the applicable court.  Don't assume anything.

Here's link to a site that will provide applicable phone numbers and other information for the various Superior Courts: http://www.courtinfo.ca.gov/courts/find.htm.  Also, if you still have trouble in locating the filing, there are companies that you can hire that can perform a search for this kind of information.
