Eg if you give the paper wallet to a lawyer, to pass on, how can you stop them spending it....and they just run off.

The key can be split into multiple parts, so the family receives one part and the trustee/attorney another:

What many are waiting anxiously for is the inclusion of encrypted paper wallets. So the trustee/attorney gets the decryption password and the family receives the encrypted paper wallets:

I changed the colour to blue for encrypted paper wallets to provide distinction between encrypted/unencrypted paper wallets - a version in the original yellow is included in case you really like yellow, just delete 'note_encrypted.png' and rename 'note_yellow.png' in its place.

This solution (encrypted paper wallets) probably isn't ready for prime time, but give it a few weeks and that will probably become a very good method for offline / long term savings that is secure.

And apparently a commercial paper wallet product (based on an open source tool) is now available with this:
