Legal Question in Family Law in North Carolina

It sounds like you did your own legal work - if so, the time to have gotten help was in the beginning and you likely could have avoided all of this - it is very doubtful an attorney would have advised you to use an October date if in fact February was the actual separation date (which based on the statements in your question February is NOT the actual separation date and you are likely not yet eligible for divorce). Anyhoo, depending on the exact wording of the agreement, potentially either the divorce complaint or the separation agreement contains information that is at best false and at worst an out right lie - neither of which is good. Using a different separation date on the divorce complaint will not invalidate the separation agreement (assuming it is properly drafted and valid) nor will the fact that it was never 'filed with the Court' because there is no filing requirement. Further, there is no such thing as 'legally separated' in NC. You simply either meet the requirements to be separated or you do not. A formal written separation agreement is not required in order to be separated. There is a very long time between February and October. It makes absolutely no sense to claim an October date on your agreement if you in fact separated in February so if you incorporate that Agreement into your divorce and a Judge catches it, you may find yourself in the proverbial hot seat having to answer up as to exactly why someone would choose to do such a silly thing. If you don't have the right answer, you could be facing a perjury charge. As to the car issue if the agreement is valid and you didn't do what you said you would do - he has a lot of leg to stand on. Of course, if he also hasn't done what he is supposed to do, you have a case against him as well. So all that said, if you did have an attorney, hire another one because your current one seems to have you very much misinformed (unless you simply just didn't pay attention). If you didn't have an attorney (which is what I expect is the case given your question) - hire one ASAP before you muck things up any more than they already are and / or end up in jail for filing a potentially perjured divorce complaint.
