Sol, never met or fished with you,but you seem like just another one of us caught in the trap. I will share with you one thing that I was told by an older,wiser guy I worked with years ago. When I was in the same boat as you. He said no matter what you do in the settlement, buy her out of your pension now or regret it later. He did this and I did too and never regretted it. I told my ex like he did his, "you can agree to this or I guarantee you that you will be getting 1/2 of nothing because I will not continue to add to this pension and I will NEVER draw a dime from it as long as you are alive." You have to let her lawyer know you are dead serious about that. You are about the same age as I was and can still put together a good retirement and fish all you want starting now.It will be tight and a little difficult to start with, but like a new mortgage it will be a very good investment down the line. Even if they call you on it, you will take less of a hit now and it will help towards starting over on a new retirement.
Good Luck Bill
