I'd like to thank you for the info but the thing that niggles me is , I never knew he claimed a Dutch pension so its a bit late for me to be looking at their laws now, also I never benefited from this Dutch pension so why should I pay it back. On top of that the bank details they give me it would cost me an extra 30 pounds to transfer that money to them, so not only would I be out of pocket for a Dutch pension I never had I'd also be out of pocket by another 30 quid to send them it. Maybe I should bill them for it see how they like it.
I could understand if my dad had left loads of money and there was ample to pay them back but when it's coming out of my pocket its a different matter but thanks for asking your friend anyway.
Appreciate all the answers.
