If you're this paranoid you could require two unrelated parties do it
together.

Thanks tracy. In the event that i die, what stops someone with access
to my digital certification pose as me? Does someone have to revoke MY
certificate in the even of my death?

Regards

Munya

Another question from yours truly. When someone has a digital
certificate, and then passes away (dies) how does the Revocation
authority get to know about this so as to disallow further use of that
persons digital cert?

The authority needs to be sent a revocation request signed by the
certificate being revoked. It is good practice to generate this
revocation request at key generation time and keep it in a safe
place. This is because if the signing key is lost such that no signed
revocation certificate can be generated it becomes impossible to
revoke.

Similarly, if the private signing key is encrypted and the owner of
the key takes the password to their grave it is impossible to generate
a revocation certificate.
