The IRS only recognizes legal separation if it required separate maintenance (similar to alimony) and cannot be easily undone - about the same process as a divorce and requires a court order. Only a few states recognize legal separation. Legal separation allows you to file as single which is much better then Married filing separately.
Why would you want to file MFS if you can file single - no advantage and a lot of disadvantages?
