I have contents insurance with some added jewellery and art clauses. But after I added it all up today I found out that this does no longer cover all the things that I own. The value of my books, CDs, records, watches and all the other stuff I own exceeds what I am covered for now. I have to apply for an upgrade and that means that I have to provide a record of those belongings. Photographs of the watches, serial numbers, etc. How does this work in your countries? I will do it because I will be hit twice in the case of loss if I don't. Quite the undertaking for sure.
