Littoral Rights

It is a type of legal right given to waterfront property. Romans have a distinct legal definition for such land rights and it was carried by British in the 1500s.

Every coastal property owner enjoys the littoral rights where they are allowed to access a public road or coastal property and they are given exclusive rights to access navigable water from his/ her property.

One can carry out property works on it like constructing a dock or launching a boat directly into the water or by mooring or by constructing a dock and such real estate investing may increase the commercial property value. 
The owner gets unrestricted access to the water but only to the median high water market, after which the government has rights to it.

One can seek opportunities in such beachfront properties or water to diversify as population growth and climate change have been threatening the quality of freshwater.
