Legal Question in Disability Law in California

You should have been served with an Order to Show Cause re: minor name change (Form NC-120). You need to provide a written statement opposing the name change and file it with the local court where the matter was originally filed no later than 2 days from the date of hearing. You may request to make a telephonic appearance, however you may very well want to oppose the name change in person.

Presuming you still retained your parental rights, including shared legal custody, you will most likely prevail. However, loss of legal custody while still retaining your parental rights is not sufficient to your right to be heard, and you still stand a good chance of opposing the matter since you are current in your support and are active in your child's life.
