Agree with LH. You should absolutely talk to a lawyer to protect yourself. A dissolution the legal instrument that takes care of dissolving the marriage (think property settlement, etc) and forms the basis of the divorce decree. You should ABSOLUTELY NOT SIGN ANYTHING UNLESS YOU ARE POSITIVE IT IS WHAT YOU WANT, AND THAT THE TERMS ARE ACCEPTABLE TO YOU.
These agreements are binding, and while it's possible to unwind one before a judge approves it, it's not an easy task, and typically requires you show duress or something.
