I have a divorce case pending in San Mateo county, California. I had the divorce papers served on the respondent by substitute service at a UPS store (usual place of mailing) pursuant to California Family Code Section 2331/CCP Code 415.20. The respondent does not have a physical address because he is homeless. My judgment packet was submitted and after waiting several months, the commissioner rejected my judgment due to "improper service". Is there a way to fight this ruling? If so, how?? I'm acting as pro per and do not have the financial means to afford an attorney. Any help would be greatly appreciated.
