Determine the proper venue. Georgia law requires that a child must have lived in Georgia for the past six months for Georgia to be the proper venue for a custody proceeding. File in the family division of the superior court in which the child currently resides. Typically this will be the same county where you or the current custodial parent live. If you are filing for divorce at the same time, fill out the petition for divorce with minor children. Parents can file for custody at any time, including if they were never married to the child's other parent, so if you are not getting divorced you need to file a separate custody petition. If you and your ex already have a custody order from a judge, you will need to file for a modification. While you can do this yourself, custody modifications are notoriously complex in Georgia, so consider having the lawyer who handled your original custody proceedings file your modification petition.
Fill out a petition for custody or petition for temporary custody. In most cases, you should complete the custody petition, which you can obtain from the family division of the superior court. If you are requesting temporary custody due to the other parent's illness, deployment or other extenuating circumstances, you must file a petition for temporary custody. Both forms require information about your child's current living arrangement and basic information about both parents. Ensure that you provide all requested information. In most counties in Georgia, you will also be required to file a child support worksheet along with the forms but some counties allow you delay filing this document until your case is before a judge. If you have a specific custody arrangement in mind, attach a parenting plan to the filing. Many Georgia counties offer blank parenting plans along with custody petitions.
Return the forms to the clerk and pay the filing fee. If the child's other parent contests your custody petition, he will file an answer and parenting plan of his own. In Georgia custody cases, parents are required to attend a parenting seminar before a judge will hear their case. Sign up to attend this parenting seminar as soon as you file your custody petition.
