we are both on state retirenment disibility . the state allows gays to marry if we do, will either one of us loose funds?

Typically, the State disability retirement would not change if you married. (sexual orientation is irrelevant). So just because two former State employees, collecting a disability retirement, met and married, there would be no impact on the pension. The State is very helpful if you call them.
If you are receiving social security disability benefits, than you are probably receiving a reduced disability pension amount. I am not certain if your marriage would have any affect on the social security benefit. A change in your social security benefit, could end up having an affect on the pension. A quick call to social security would answer your question. Good Luck.
