Am I entitled to any money from the sale of a jointly owned vessel, which was sold with my name forged on the documents and without my knowledge?

My ex-husband's second wife forged my signature on a USCG documented vessel title (1986 Ocean Yacht SS Value when new $250,000.00) that was jointly owned by me and my ex-husband. Then my ex-husbands second wife committed suicide. I believe this was about 2004. I also believe my ex-husband had my name removed from all documents around this time. When my ex-husband's father died, my ex was to inherit his father's vessel at witch time he would sell the vessel he and I owned. I found out his father died in late 2012 or early 2013. When my ex-husband never contacted me for my signature, I realized his second wife had forged my name. I checked with NOAA/USCG sight (http://www.st.nmfs.noaa.gov/st1/CoastGuard/VesselByName.html) and found that my ex-husband did sell our vessel without me ever signing anything.
