Can anyone legally fill out a Warranty Deed in the State of Florida? Also, is there a website I can go into to do this from English to Spanish?

Not really, a title company or a real estate attorney, or the person can do their own ( but I would not advice it on a warranty deed)

The issue with a warranty deed is that you are going to warranty things, and in doing this you need to do a title search and be sure things are correct so you don't warranty something you will have to pay off money on.

So if you are doing a warrnty deed I would never do one without a real estate attorney.
