Documents that are authenticated by a notary public are almost always for use overseas. This raises the question of how to send them to the destination. The options are ordinary airmail, Royal Mail “Tracked and Signed” and courier services such as FedEx and DHL, which deliver to the addressee. If I am instructed to send a document overseas for a client, I will only use FedEx or DHL. This is because they reliable and fast. Sadly, each year a number of of my clients send their documents by some form of mail which fails to deliver and causes the client, delay, extra cost and sometimes consequences of missing a deadline. All systems are fallible, but the courier services very rarely fail to deliver and the cost is usually much less than having to repeat the document formalities.
