There are several reasons why the name of a child (registrant) on a birth certificate may be changed. Arizona Revised Statute §36-338 and Arizona Administrative Code R9-19-118 allow that within the first year following birth the parents may change the registrant's name. After one year these laws require a court order to make this change.

In the event the registrant's birth certificate is a delayed birth certificate Arizona Administrative Code R9-19-120 applies. These requirements are somewhat different.
Changing a child's name within one year of birth.

The name of the registrant as it is being used is different from what is on the birth certificate

For a child within one year of birth:

In order to change a name a minimum of two things are required. These include an affidavit plus at least one independent factual document corroborating the affidavit. The sufficiency of these documents will be determined by the State Registrar who may require additional documentary evidence. Both parents (or one parent if only one parent is listed on the birth certificate) must notarize the affidavit.

The independent factual document corroborating the registrant's name must have been created within the first six months following the registrant's birth. Examples of what may be accepted include: the registrant's baptismal record, blessing certificate, immunization record, hospital record, medical record, etc. The document must show the registrant's complete and full name, and date the document was created.
