I don't know whether the book I recommend will fit your criteria - but regardless .... I nominate "The law of the sea" by Dave Gerard (aka Dov Preminger). It was published in August 2021 (hence my questioning whether it fit your criteria) but I just found out about it recently.
The story centers around the mysterious death of a deep sea diver who found a centuries old shipwreck and the courtroom drama that ensues as to owns the found. It's a great read!
