Legal Question in Real Estate Law in California

Re: How to obtain relief from default judgement in unlawful detainer case

Your best path for relief will depend upon whether the action is in small claims or municipal court, whether the landlord has already applied for entry of default and/or a writ of execution.

There is a limited possibility of relief from default, especially if you have solid reasons for defaulting and for breaching your lease (if you did). Carrying out any action for relief will at least require consultation with a local lawyer, and maybe you'll have to retain one, unless it's a small claims action.
