Thanks for posting the plat, Local.
Hmmm. I looked at the Walton County Property Appraisers web site and saw that Lot 3, which is gulf front on the lower right corner of the plat, is the only one in the subdivision that shows lot lines to the water. Looked at the Clerk's documents linked to the appraiser's site, and the older of the sales show transfer of Lot 3 Beach Highlands subdivison, etc., with no legal description of the lot. The most recent sale however shows an attached legal description which describes the lot as bounded by "to the water's edge of the Gulf of Mexico" as a part of the legal description.
I have seen this before. Can anyone tell me how lots in subdivisions with a plat that clearly shows the beach as not a part of the lot suddenly include similar language and now 'own' the beach??
