The quick answer to that question is: you can’t really.
It is true that some states (like California) allow people to file for “Legal Separation” – which allows you to deal with a number of issues without actually obtaining a divorce.
How long do I Have to be Separated before I Can Get a Divorce in Virginia?
The quick answer is that it depends but most likely you will have to be separated for one year. Virginia, like many states and commonwealths, requires that you be separated for a period of time before you and your spouse can get a divorce.
Generally, the required separation period is one year. § 20-91(A)(9) allows parties to obtain a divorce after the parties have lived separate and apart without cohabitation and without interruption for more than one year. It is important to note that you cannot file for divorce on these grounds until the grounds exist.
