No. A "legal" name change of a minor requires the consent of the other parent and a court order.My question involves name change laws in the State of: Missouri and kansas. Can a ex legally change the name of a child without notifying the father?
However, it is common for the custodial parent to have the child use the parent's last name without consent and can get away with it as long as the child's last name is accepted by schools and government. Eventually, there will be issues when some entity or other requires a birth certificate as identification and then the parent will have to address the requirement of consent for a court ordered name change.
Run the child's current last name or your ex's married name through the court records of whatever counties they have been living in and see if there is a case file for a name change.She left me sitting a friends house with a broke leg and never came back. She told me she had to choose between them or me. She picked them. I never heard from her again. We were never married but the child had/has my last name. The child now uses her mother's married name. I could never find her. The child told me that she has always used that name. That is the name her mother told her it was. How can I find out if she changed her name.
