For many couples. the opinion of Maryland Attorney General asserting the equal treatment of out-of-state same-sex marriages has led to an unhappy inquiry into state divorces statutes, to ensure that marital rights are not enforced by an estranged spouse.  While the statutory requirement of 12 months' residence in the state is not unusual, the particular claims required of a divorce filing are.  For starters, Maryland provides for no amicable divorce–couples must be living apart for at least a year or one party must be charged by the other with abuse, neglect, or adultery.  And when it comes to adultery, the definition is limited to heterosexual extramarital contact, thereby putting that charge out of the reach of spouses betrayed by same-sex extramarital affairs.
