The only thing I can really suggest is to educate yourself on the laws of your state in the area of divorce and/or separation.
In my state, a divorce or separation decree MUST be accompanied by a settlement offer. Of course one is not required to agree to the settlement but it must be included with the separation/divorce decree.
I live in a "fault" state so things are a bit different than "no fault" states. Here though even a separation agreement requires division of assets. And there are very specific timelines on how long you have to respond to the filing.
Forms are available at the courthouse or online for most states but even if an individual (not legal counsel) files them they still must be filed correctly. That is why I suggest you educate yourself on the particulars of your state (or get a consult with a family law attny).
