Hello,
Is this in the UK?
If it is ...
I had a quick look online and came up with the `heir hunters association`
Might be worth contacting them if you`re concerned.
http://www.heirhunters-association.org.uk/index.phpBut i would also perform your own search - I searched for "Heir Hunters asking for id"
Read through the results and make a decision from there.
Best Wishes
Jacki
