Often in the real world people are unable to sign documents because they are away on holiday or some other important business. In situations like this there is normally a possibility for some other suitably authorised person to sign on behalf of the original signer. Within SigningHub we have built support for delegated or so called PP signatures. Set-up is simple, just identify the person who can sign on your behalf and the date range when this is allowed (e.g. whilst you are on leave).
