there was a law in MD earlier this year that stated 1 year without intercourse can be used as grounds of separation even if couple lived together. is this true?
What you are referring to is not a law, it is an appellate opinion..the case is Rickets v. Rickets, you can review it on the court of appeals website.
it does state that under certain conditions, a divorce can be granted as constructive desertion if one party is refusing to have relations with the other..it does however leave the door open to deny such relief as well.
You would be best to review the specific facts of your case with an attorney before proceeding.
