Sunny, Sorry you got blindsided. Remember, you will be just fine, even if this is not what you wanted. Also, it ain't over til the fat lady sings, so hang in there.
My $.02: I would talk to your L immediately. The laws are totally different in every state and you will risk a lot more than an hour fee with a L if you make a mistake.
That said, in FL, you can either A. both sign the paper work and then turn it in to the court or
B. one spouse can file and have the other one served.
Either way is legit. For option A I'm not sure if the L has to put in a notice with the court in advance and get a case no. assigned. Not much help, but just reinforces that you need to see a L.
Take care of yourself, SD
