Legal Question in Civil Litigation in California

Your question is way to simplistic to answer and the answer would depend on a large number of facts that you do not even begin to provide. Just for example, if you are suing a landlord and you made your rent checks out to a management company and sue in the name of the management company for something that is the landlord's responsibility, sure your case will be dismissed. If you are suing your landlord whose name is Jonathan Smith and you always made your rent check out to Jon Smith, it probably won't. Obviously few dismissal motions are that simple, and with no information or context for your situation there is no way to answer you.

You should file an opposition to their motion, and make the legal points necessary.
