Section 14-3-414 - Service of process; order of custody(a) In proceedings under this act, service of order to appear or other process within the state shall be made by the sheriff of the county where service is made, by his undersheriff or deputy or by any law enforcement officer or responsible adult not a party to the proceeding and appointed by the clerk.(b) Within the state, service of order to appear is made by personally delivering a copy of the order together with a copy of the petition to the person ordered to appear, provided that parents of a child may both be served by personally delivering to either parent two (2) copies of the order and petition, one (1) copy for each parent. A child under the age of fourteen (14) years is served by delivering a copy of the order together with a copy of the petition to the child's parents, guardian, custodian or other adult having the actual physical custody and control of the child or to a guardian ad litem or attorney appointed for the child.(c) If it appears to the court by affidavit that the parents, guardian or custodian of the child cannot be found within the state, the court may order personal service outside the state or service by certified mail with return receipt requested signed by addressee only. The state agency having custody of the child shall also file an affidavit with the court explaining the efforts made to locate the missing parent when the address of the child's parents, guardian or custodian is unknown and cannot with reasonable diligence be ascertained, and the court shall appoint a guardian ad litem to represent the child and to receive service of process.(d) Service by certified mail is complete on the date the clerk receives the return receipt signed by addressee. Personal service either within or outside the state is complete on the date when copies of the order to appear and petition are delivered to the person to be served.(e) When personal service of order to appear is made within the state, service shall be completed not less than two (2) days before the hearing and when made outside the state, service shall be completed not less than five (5) days before the hearing. However, notwithstanding any provision within this act, the court may order that a child be taken into custody as provided in W.S. 14-3-413 or that a child be held in shelter care pending further proceedings as provided in W.S. 14-3-409, even though service of order to appear on the parents, guardian or custodian of the child is not complete at the time of making the order.(f) If the person's residence is unknown, service may be had by constructive service or by publication as provided in the Wyoming Rules of Civil Procedure.
