I hope you have read all of the California regulations regarding marriages. It is really, really important that the officiate be authorized in the State of California to conduct the ceremony for you, and that you have at least one witness other than the officiate to sign the license. Otherwise, the local county will not recognize the marriage as being valid.

Hopefully, you have read all of the information:

There has been a lot of anecdotal information posted here (which might not be accurate); be certain of the facts and requirements before proceeding.

Have you contacted the Inyo County Clerk's office? They will be a better source of information for you than second-hand reports in this forum, however well intentioned.
