Social security from ex...question...

I was married for 20 years, had one daughter with the ex. A divorced substitute teacher told me today that I would be entitled to a portion of my ex's social security benefits when he starts receiving them. Since I allowed him to write the divorce himself, not touching any of his investments or retirement, I am wondering if I also relinquished any rights to Social Security as well. The lawmaster who presided over the divorce agreement even questioned me about the amount I was relinquishing to him, and I just sheepishly agreed and signed the papers, so happy to finally be free.
The substitute teacher today says it's the "law" that I receive a portion of his SS benefits, but I'm not sure. Anyone else here know about this?

I guess... I will say very vauguely.. that I remember this.. based on length of time married and such... and I don't think you can have "signed" your rights away.. not on social security... other yes..

you can call and ask.. but I would ask more than once ask SSI.. as I have gotten "different" answers.. from different folks.. and they have a web site too..

in my state if the marriage is over 10 yrs and you do not remarry then you are entitled to his ss if you become disabled or reach retirement age. now if you would get more from his or yours would determine which one you would or could draw from.
