UK pensioners living overseas need to stay on top of their paperwork, or they'll lose their state pension. On a regular basis, expats aged over 75 receive forms from the Department of Work and Pensions, asking them to prove they are still alive. Each time, they have just nine months to complete forms and send them back. If they miss the deadline, the government will assume they have passed away, and their pension will be cut off. (AOL)
