Its probably too late, but you really need to set an appointment with a Lawyer that deals with this stuff before you arrive. I suggest you get everything done all at once. This is not a one time, 10 minute visit. Having names to appoint to the positions is very important, you are better off to have separate people serve in the different functions, and you need all their information. You also need to be sure they want the responsibility and are people you can trust.

For us, the process involved 3 separate visits with the Lawyer.
The 1st was to determine what we wanted in the paper work.
The 2nd was after the lawyer had written everything up to be sure it was the way we wanted.
The 3rd was with the completed documents to be sure they were correct. If corrections would have been required in either the 2nd or the 3rd visit, a 4th visit would have been necessary to be sure the finished documents were correct.
The whole process was spread over about 3 months time, and we were less then a mile from the Lawyer. The cost here was just over $1,000, 2 years ago. Gene
