In Virginia - if both parties agree about a divorce, does there have to be any waiting period.

Short answer:  No.  If both parties are in agreement as to all potential issues, as divorce can be granted after a six-month separation, as long as there are no minor children and the parties sign a written property settlement agreement.  If there are minor children or no written agreement, the parties must wait for a one-year separation period before filing for 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.
