What DD said, and it MUST be an Atty. VERY familiar with FEDERAL Pensions........... the 50/50 thing is nigh impossible to get past..........
But there is a way that it does NOT carry over into the monthly pension benefit.................
Find the Lawyer that knows about that...............
I worked with a guy that left the specific wording out of the final agreement, he now pays 50% of his retirement check until she passes or marries................. the later, of which, she will likely never do!!!
