if we both agree how long will it take

If you have already been separated the required amount of time, then the divorce itself can be done in a few weeks, if you are both cooperating fully.  You would have to add time for any delay caused from mailing documents back and forth.  If you don't have any kids you can get divorced after only a six months separation, but in order to do that you must have a written property settlement agreement.  That must be signed BEFORE you can file the divorce, so add some time to complete that process.  If you do have kids then you must be separated a whole year in order to file a no-fault divorce. 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.
