§ 3111.12.

(A) In an action under sections 3111.01 to 3111.18 of the Revised Code , the mother of the child and the alleged father are competent to testify and may

be compelled to testify by subpoena.  If a witness refuses to testify upon the ground that the testimony or evidence of

the witness might tend to incriminate the witness and the court compels the witness

to testify, the court may grant the witness immunity from having the testimony of

the witness used against the witness in subsequent criminal proceedings. (B) Testimony of a physician or certified nurse-midwife concerning the medical circumstances

of the mother's pregnancy and the condition and characteristics of the child upon

birth is not privileged. (C) Testimony relating to sexual access to the mother by a man at a time other than the

probable time of conception of the child is inadmissible in evidence, unless offered

by the mother. (D) If, pursuant to section 3111.09 of the Revised Code , a court orders genetic tests to be conducted, orders disclosure of information regarding

a DNA record stored in the DNA database pursuant to section 109.573 of the Revised Code , or intends to use a report of genetic test results obtained from tests conducted

pursuant to former section 3111.21 or 3111.22 or sections 3111.38 to 3111.54 of the

Revised Code, a party may object to the admission into evidence of any of the genetic

test results or of the DNA record information by filing a written objection with the

court that ordered the tests or disclosure or intends to use a report of genetic test

results.  The party shall file the written objection with the court no later than fourteen

days after the report of the test results or the DNA record information is mailed

to the attorney of record of a party or to a party.  The party making the objection shall send a copy of the objection to all parties. If a party files a written objection, the report of the test results or the DNA record

information shall be admissible into evidence as provided by the Rules of Evidence.  If a written objection is not filed, the report of the test results or the DNA record

information shall be admissible into evidence without the need for foundation testimony

or other proof of authenticity or accuracy. (E) If a party intends to introduce into evidence invoices or other documents showing

amounts expended to cover pregnancy and confinement and genetic testing, the party

shall notify all other parties in writing of that intent and include copies of the

invoices and documents.  A party may object to the admission into evidence of the invoices or documents by

filing a written objection with the court that is hearing the action no later than

fourteen days after the notice and the copies of the invoices and documents are mailed

to the attorney of record of each party or to each party. If a party files a written objection, the invoices and other documents shall be admissible

into evidence as provided by the Rules of Evidence.  If a written objection is not filed, the invoices or other documents are admissible

into evidence without the need for foundation testimony or other evidence of authenticity

or accuracy. (F) A juvenile court or other court with jurisdiction under section 2101.022 or 2301.03 of the Revised Code shall give priority to actions under sections 3111.01 to 3111.18 of the Revised Code and shall issue an order determining the existence or nonexistence of a parent and

child relationship no later than one hundred twenty days after the date on which the

action was brought in the juvenile court or other court with jurisdiction.
