I am prior military and my STBXW is still active. I don't believe it is possible for you to lose more than 50% of your pension to her. I don't know what state you are in, but most states I do know about use the same formula basing it on the number of years the non-military spouse was married to the military member while they were on active duty divided by the total years of service times 50%. For example if you served 20 years and you were married to your W for those entire 20 years she would get 50% (20/20 X .50). If you served 20 years and were married for 15 of those years she would get 37.5% (15/20 X .50).
