No default may be entered in any proceeding unless a request has been completed on a Request to Enter Default (form FL-165) and filed by the petitioner. However, an Income and Expense Declaration (form FL-150) or Financial Statement (Simplified) (form FL-155) are not required if the petition contains no request for support, costs, or attorney's fees. A Property Declaration (form FL-160) is not required if the petition contains no request for property.
For the purpose of completing the declaration of mailing, unless service was by publication and the address of respondent is unknown, it is not sufficient to state that the address of the party to whom notice is given is unknown or unavailable.
