Make it a point to ask for a sit-down with an experience lawyer. I once asked for this and got an interview with two very young lawyers who needed to read a book to answer every question I had. It was at that prominent firm's office in Sosua. Yes, consultation is free.
In my experience, lawyers in the DR don't specialize in anything, and that's a problem. After this time, I asked for another meeting and said what it was for, and that given my previous meeting, I wanted to make sure I wasn't getting an inexperience lawyer. We had a meeting with one of the most senior lawyers. He was great, but couldn't answer a simple question that any lawyer would have known: if we own property and community laws apply, then if one of us dies, the 50% belonging to the other party is not part of any inheritance, it's simply ownership, please confirm. He did call me to confirm I was correct several days later.
