Can I get a child support order without getting a legal separation or divorce?

If the persons have never been married, yes. You may file a petition directly with the court; a private attorney may file on your behalf; or the local Division of Child Support Services may help you establish a support order, as well as paternity, if that is an issue in the case. If you are currently married, you will need to contact an attorney or research the Arizona Revised Statutes to determine if child support can be ordered without filing a separation or divorce proceeding in court. For information regarding child support while married, contact the Division of Child Support Services.
