Yes. This had occurred to me. Don't like to tell lies but not married in England so might be possible, could cause more headaches than its worth.
My own estimate of my pension was about 100 pounds so when their estimate came in at 165 it was a nice surprise but I'm pretty sure that when it comes to eat my estimate will be nearer to the actual. In any event, better than a poke in the eye with a sharp stick.
