Rather than type out the treasure act by hand I have posed a link here for you to follow which will take you to the official web site on the subject. The documents are of course protected by copyright and it would probably take an age to clear all the red tape if I were to post a copy here.
The Treasure Act 1996
There is a shortened and easier to read leaflet version of the Treasure Act 1996 which you can obtain from most rallies and other officially supported metal detecting events. It is also important to check the laws regarding treasure trove items on a regular basis as the law has a habit of changing when you least expect it and it is always nice to know exactly where you stand.
