Greetings. First, let me sympathize how frustrating it is when you pay to have an agreement drafted, send it to your spouse, and then hear NOTHING! It sounds to me like your spouse has all the funds in this situation. Sometimes, all the talking, letter writing, and e-mailing I do in a similar situation is fruitless if the spouse does not care to respond.
First, remember that if the divorce is filed and you have not dealt with the equitable distribution (property division - including the car) in a separation agreement or filed for the same in court, that you LOSE the right to ask the court to divide your marital assets.
Therefore, I advise you to push your X to respond to you quickly about the changes he wants to the separation agreement. Also, the separation agreement with you changes will not work if you file them for a divorce hearing. Look at the documents we provide here on our website concerning filing for divorce. It sounds to me like you need to file for equitable distribution (to get the car in your name). Take note though that it will cost a lot more than the $750.00 you spent. Best of luck!
