Loretta Pangelinan and Kathleen Aguero have lived together as a couple for several years, and their lawyer argues there is nothing in Guam law that prohibits the 28-year-olds from entering a matrimonial agreement.
"I am extremely confident of our victory in court. The law is very clear," attorney Bill Pesch said, adding that court documents were being filed.
Co-attorney Todd Thompson said the women were "denied equal protection of the laws" by the department's refusal to accept their application.
Guam Attorney General Elizabeth Barrett-Anderson issued a statement today supporting the Health Department's refusal to process the marriage application.
Guam's marriage statute was based on the 1939 version of California's civil code "on consent to marry between a man and woman", she said.
"Although the definition of marriage is a consent of parties, which implies gender neutrality, Guam law conditions marriage upon the act of solemnization that is only permitted between a husband and wife," she added.
The Guam tax department does allow same-sex couples married elsewhere but living on the Western Pacific island to file joint tax returns.
