Okla. Stat. tit. 10, § 10-7700-622: Enforcement of order for genetic testing - Default

A. An order for genetic testing is enforceable by contempt.

B. If an individual whose paternity is being determined

declines to submit to genetic testing ordered by the court, the

court for that reason may adjudicate parentage contrary to the

position of that individual.

C. If a defendant fails to answer, or to appear for hearing or

genetic testing after being ordered to appear, and all other duly

served defendants have been excluded as possible fathers by genetic

testing, the court shall enter an order establishing the defendant

who failed to answer or appear as the father.

D. Genetic testing of the mother of a child is not a condition

precedent to testing the child and a man whose paternity is being

determined. If the mother is unavailable or declines to submit to

genetic testing, the court may order the testing of the child and

every man whose paternity is being adjudicated.
