Assuming that the Separation Agreement was correctly done, your boyfriend can file without waiting any longer.
The preparation of the Divorce Papers should be done by an experienced attorney to make sure that it is correctly prepared.
These matters are too important to leave to self-help, and mistakes may come back to haunt you many years down the road.
If you’re living in the New York City metropolitan area, I strongly suggest you call me at 212-370-1660 to discuss preparing the papers.
