(a) Oklahoma Child Support Services (OCSS) objects to a paternity challenge proceeding when:

• (1) there has been an acknowledgment of paternity executed in Oklahoma or another state and not rescinded within the allowable time, which is 60 days;  [45 CFR § 303.5 and 10 O.S. §§ 7700-301 through 7700-307]  • 1 & • 2
• (2) the child has a presumed father and a party initiates a challenge more than two years after the child's birth;
• (3) paternity has been established by a district or administrative court order.  [10 O.S. § 7700-636]  • 1

(b) OCSS does not object to a paternity challenge proceeding when:

• (1) the parties neither cohabited nor engaged in sexual intercourse and the husband never held out the child as his own; or
• (2) the mother, legal father, and biological father agree to adjudicate paternity.  [10 O.S. § 7700-607]

(c) When a paternity challenge proceeding is brought by a child under 10 O.S. § 7700‑637, the state’s attorney reviews the facts of the case and determines whether or not an objection is appropriate under the circumstances.
