I am in NY and was wrapped up in a horrible case (still am actually) for close to three years.
Something is not right here.
First of all, there is no criteria for spousal support; instead it is based on a list of factors established by the courts.
Second of all... if your H filed a divorce petition he MUST include a statement to support the grounds he has filed under.
It seems you are talking about disclosure when you say "drafts" and what you are saying is NOTHING like I had to fill out and trust me I had to fill out a ton of stuff (started as a divorce then went to a Separation Agreement almost 18 months later).
What do you mean by mediation? A pre-trial hearing?
If your H refused to provide supporting documents for financial disclosure you can either (A) both waive your rights to full disclosure or (B) judicial intervention will be requested on YOUR behalf by YOUR attny for your H's non compliance.
I have binders and binders of info on this BS and something is not right with what you are understanding.
