I've been married 8 1/2 yrs, but marriage has never been consummated. Can marriage be annulled? How long would it take?

Annulments must be filed within two years of the date of marriage, so that is no longer an option for you.  And you would have to show medical impotence in order to sustain an annulment, not just that you did not have sex for some other reason.  But you can seek a divorce.   To file for divorce you must have grounds for divorce.  The most common ground is living apart for a year.  Or if you can prove fault against the other party, you can file right away.  The most common fault grounds are adultery, cruelty, and desertion.  It sounds like you may have a claim for cruelty. This answer is given in accordance with the laws of Virginia and may not be applicable in any other state.  It should not be construed as legal advice, as that would require a more thorough analysis of all of the facts involved in a specific case.  If you need further information or assistance, please feel free to contact my office for a consultation. Case results depend upon a variety of factors unique to each case. Case results do not guarantee or predict a similar result in any future case.
