My question involves name change laws in the State of: California

I have recently been served with a notice that my ex-wife is petitioning to change our 15 year old daughters last name from her legal name, (mine) to her mothers maiden name. I am in the process of writing an objection to this but am wondering under the following circumstances: (see below) what the mothers chances are and if I should prepare more?

  • The mother has physical custody with reasonable visitation to me.
  • We share legal custody
  • I have always paid the required child support $1300.00 per month and spousal support $1100.00 on time and have never been delinquent.
  • I have limited visits with my daughter by her choice but do stay in contact and try to arrange for time to see her.
  • I do not have any issues with the law or anything in my past that the mother could use against me as far as tmy daughter being embarrassed or teased about her last name.
    • I lived with and raised my daughter with my wife, at the time from her birth until the divorce, so she was 12 years old when we divorced, so I was, and am part of he life.

    Does the mother really have much of a justification legally for this name change?
