Me. Stat. tit. 19-A § 1608
When it appears to the department that there may be more than one alleged father, the department may maintain proceedings against each alleged father, simultaneously or successively. Failure to serve a notice on an alleged father does not bar the department from maintaining a proceeding under this chapter against any other alleged father. [1995, c. 694, Pt. B, §2(NEW); 1995, c. 694, Pt. E, §2(AFF).]
When the department initiates proceedings against one alleged father when there may be more than one alleged father, the department may require the parties to submit to blood or tissue-typing tests prior to accepting an acknowledgment of paternity from the alleged father. If the alleged father refuses to participate in testing, the department may file the action in court. [2001, c. 554, §5(NEW).]
