The Agreement Concerning the Shipwrecked Vessel RMS Titanic is a treaty open to all states regarding the protection of the shipwreck of the RMS Titanic. Following the passage of the RMS Titanic Maritime Memorial Act in 1986, the United States began negotiations in 1997 with the United Kingdom, France, and Canada toward an agreement to protect the wreck. The agreement was signed by the UK in 2003 and by the US in 2004. It was not until 2019 that the US ratified the agreement, bringing it into effect on 18 November, the day of deposit of the instrument of ratification.
