By documented in Florida
I suspect you are not saying that the title was issued by the state. I assume you mean that the home port was Florida
and the owner registered it in Florida to pay taxes
but relied upon the Federal documantation (title).
Now the boat is in Texas-which as I recall
(used to live there) doesn't register documented vessels.
Have the owner reinstate the Federal documentation (forms are online- Google
it) and then transfer it to you. He has to pay a penalty fee, but them is the breaks. It will take a long time to get through the USCG bureaucracy and get a good title.
If you don't go through all of that BS then use a documentation service
to get through this conundrum. They will know how to apply for the reinstatement simultaneously with applying for your new document.
If you go this route
, then I would check with Texas
and Florida for state titles which now that the Federal one has expired, may be valid and for all you know the boat may have been sold
The best way would be to wait until a current
Federal document is in hand. That trumps any state title.
