Lincslass, having divorced, remarried - and taken several years off work, bringing up children, I somehow managed to have acquired two different NI numbers. By chance, an employer found out. I may have lost all my earlier pension contributions otherwise!
The same happened with a family member, served in Armed forces, then left went to live in Germany. No trace of that service on Uk Pension records, but when claiming German pension, they found her Army records. Either our side didn’t really try, or didn’t know how to access them. Sometimes I wonder how many have missed out on money owed.
