You first need to look at the deed to the property you have that has an ocean view to see if there is a "view easement" in favor of your property which would allow you to have a view easement. If there is one, you need to read the scope of the easement, ascertain which neighboring properties are subject to the view easement and then if you have a view easement for the ocean over the neighbor's property who has let it go wild with weeds and vegetation, you can write a letter seeking that it be cleaned up to protect your view.Most likely the deed to your property does not have a view easement in its favor. If so, you could contact your neighbor and offer to pay to have the vegetation removed or trimmed back to have a betetr view of the ocean. If the neighbor is unwilling to do so, you might want to see if the local fire marshall deems the excess vegertation a fire hazard where the neighbor would be reuired to reduce the growth of weeds and other vegetation which in the end could open up your view of the ocean.It is always best to work with a neighbor to resolve an issue as opposed to making the neighbor not want to help you.
