I was married to a military man for over 10 years he remarried I didn't he is now deceased can I still claim any military pension

How was this handled in your divorce?

Here is some info. A lot more is available on the website:

"In most divorces, one spouse or the other has a pension. The pension is a actual chunk of money that is being held in an account somewhere. A person could actually remove the money from this special account, although, I wouldn't recommend it, since there are severe tax consequences for doing it. But, my point is that this money exists now. If the person died, the money would still exist and go to his heir.

Not so the military pension. In fact, to be truly accurate, there is not such thing as a military pension. There is no chunk of money sitting anywhere. Instead, when a person retires from the military, he gets "retired pay." Every year, the Congress votes on a budget. As part of that budget money is set aside to pay military retirees. The retiree gets paid as long as he is alive. Once he dies, the right to be paid dies with him. There is no chunk of money going to his heir."
