Me. Stat. tit. 32 § 13194
Licenses expire on December 31st, or at such other times as the Commissioner of Professional and Financial Regulation may designate, of each biennial period for which it was issued, except those licenses issued under section 13200. The director shall issue a renewal license for each ensuing biennial period in the absence of any reason or condition that might warrant the refusal of granting a license, upon receipt of the written request of the applicant, the biennial fee as set under section 13007 for the license and upon the applicant presenting evidence of compliance with the requirements of section 13197. The director shall deny a renewal license to any applicant whose license has lapsed for more than 90 days, unless the renewal license applicant passes the license examination designated by commission rule for this purpose. [2007, c. 402, Pt. BB, §23(AMD).]
