If your divorce is going to be quick and easy, I would definitely go the easiest route possible.
I can see where hiring a lawyer would create animosity. Since they are working for you and representing you, it will seem as if you are the one being abrupt and forward. I hired a piranha who was willing to do anything and everything for me. We wheeled and dealed, but I think I came out with the better end of the stick. Our case never went to court.
I know this sounds weird, but I requested to be served. My lawyer friend (not my lawyer) adviced me not to waive any rights to include being served. When my ex's lawyer called me to arrange a time for me to go to his office and sign the waiver, I informed him that I wanted to be served. Of course, his lawyer accused me of "stalling." In the end, do what is best for you. Every case is different.
Good luck to you.
All my best, alamogirl
