It's kinda like living in Louisiana. Let me explain. The USA is under Civil Law Code. Except Louisiana. They are still under Napolian Law. Viva la France! My home state. The banana republic of the US.  Not unlike Nica. Every time I do a lease in Nica I get a lawyer. I am still not sure if a degree is required. Lotsa files and a desk full of papers spread about is a dead giveaway that this person is a lawyer. Most have a wooden, chain hung and swinging sign saying Lawyer outside there door. Now if you wish to verify this fella, go and see the nearest priest at the local church in the town square. Ask him for a lawyer reference. Preferably a parishenor who attends his mass every Sunday. This will possibly keep you away from the lawyers who graduated from the "Doey, Cheatem & Howe" school of law.
One other thing. It would be a plus for you to bring along a trusted bilingual person A bilingual priest would be great. Of course a $25 or so donation will seriously aid your in this endevor.
Don't let the lawyer use his translator. Use someone you trust.
