California Amendment To Complaint is a legal document that can be used to make changes to a complaint that has already been filed with the court. The amendment must be filed and served prior to the court hearing the original complaint. The amendment must be in writing and signed by the party or attorney filing the amendment. There are three types of California Amendment To Complaint: 1. Unilateral Amendment: This type of amendment is filed when a single party wants to make changes to the complaint without the consent of the other party. 2. Bilateral Amendment: This type of amendment is filed when both parties agree to make changes to the complaint. 3. Amendment by Order: This type of amendment is filed when the court orders changes to a complaint.
