"No guarantees", "might" and "iffy"?
Nothing quite as safe as being noncommittal. Right, ajax? Totally uninformative, but free from repercussions. Then perhaps you really had nothing to add to the thread but added it anyway.
The fact is, ajax that New York is comparatively liberal in awarding post divorce maintenance, durational or nondurational as well as pendente lite. All depending on a number of various factors.
And here the OP's circumstances are favorable with respect to two of the major factors. (1) Two decades as intermarried husband and wife. (2) The unlikelihood of her ability to become self supporting.
Moreover, if there are any states that do not allow the family court to assess the husband with the wife's legal costs (or at least assist her in defraying those costs) when a disparity of income or sources could result in prejudice to the wife, perhaps you could name them.
Can we talk gobbledy-gook? Fact is - even the best, most experienced attorney (in ANY discipline of law) will not provide a guarantee of a particular outcome. One who does is, at best, a charlatan. Is SS POSSIBLE? Yes. LIKELY? Yes. But never guaranteed.
Nor are legal fees GUARANTEED. They MAY be awarded. It may be very likely they will be awarded. But it is not DEFINITE. To even imply otherwise is more than foolish, lattie-boy. It is misleading and unfair to the OP.
OP- Hope for the best, plan for the worst. The more you educate yourself, the better. At very worst, if you have to pay for your own attorney? S/he will not have to explain every piece of minutia to you, lessening the amount of time you use. Also spend some time calling lawyers to see who may offer a free consult and/or work with payment plans. As difficult as this is, now is the time to steel yourself and learn all that you can. Read posts here, search state statutes, make copies of all important paperwork - especially financial, titles, anything to do w/assets.Learn what your rights are. You are in a unique position in terms of having the time to spend while he is at work. Take advantage of that.
