(1) An unchallenged acknowledgment of paternity shall be ratified under KRS Chapter 213 without the requirement for judicial or administrative proceedings. If a genetic test is required, the court shall direct that inherited characteristics be determined by appropriate testing procedures, and shall appoint an expert qualified as an examiner of genetic markers to analyze and interpret results and to report to the court.
(2) In a contested paternity case, the child and all other parties shall submit to genetic testing upon a request of any such party which shall be supported by a sworn statement of the party, except for good cause.
(3) Genetic test results are admissible and shall be weighed along with other evidence of the alleged father's paternity.
(4) Any objection to genetic testing results shall be made in writing to the court within twenty (20) days of receipt of genetic test results. If the results of genetic tests or the expert's analysis of inherited characteristics is disputed, the court, upon reasonable request of a party, shall order that an additional test be made by the same laboratory or independent laboratory at the expense of the party requesting additional testing. If no objection is made, the test results are admissible as evidence of paternity without the need for foundation testimony or other proof of authenticity or accuracy.
(5) Verified documentation of the chain of custody in transmitting the blood specimens is competent evidence to establish the chain of custody.
(6) A verified expert's report shall be admitted at trial unless the expert is called by a party or the court as a witness to testify to his or her findings.
(7) Except where the Office of the Attorney General administratively orders genetic testing, all costs associated with genetic testing shall be paid by the party who requested that the action be brought pursuant to KRS 406.021.
(8) When administratively ordered, the Office of the Attorney General shall pay the cost of genetic testing to establish paternity, subject to recoupment from the alleged father when paternity is established. The Office of the Attorney General shall obtain additional testing in any case if an original test is contested, upon request and advance payment by the contestant.
