Hi, my first thought is to contact more than one atty and ask for a free consultation, many do these. Have a list of questions made up before hand.

My stbx is collecting state retirement and he told me the same thing but I know for a fact that with state pension, I am entitled to part of it! The normal formula is the yrs of employment divided by the yrs of marriage DURING his/her employment.
My stbx receives 2400 mo. and was employed for 12 yrs. I was married to him for 6 of those yrs so my share will be 600 mo.
But PLEASE consult w/a few attys before signing ANYTHING!!
Good luck
