MERCHANT SHIPPING ACT 1995
""All wreck material which comes from UK territorial waters, and any wreck which is landed in the UK from outside UK territorial waters must by law (Section 236 of the Merchant Shipping Act 1995) be declared to the Receiver of Wreck.
Wreck is defined as anything which is found in or on the sea, or washed ashore from tidal water. All items which are raised, regardless of age or importance, must be reported to the Receiver of Wreck.
Finders who report their finds to the Receiver of Wreck have salvage rights. The Receiver of Wreck acts to settle questions of ownership and salvage.
This part of the 1995 Merchant Shipping Act is administered by the Maritime & Coastguard Agency through the Receiver of Wreck.""
