The thread at http://www.nicaliving.com/node/20849 has become a bit big and, as is usual, drifted from the original subject. This thread is to discuss one point that has evolved there -- gray areas.
The system in Nicragua encourages the use of and expansion of gray areas. Sometimes it is that there just isn't any right way to make something happen. That is, some regulation translates to "no, you can't". To take a specific example, the Public Registry in the department of Estelí had decided that a non-resident cannot be the owner of an S.A. (corporation). But, other departments (that is, all others that have been tried) don't have an issue with a non-resident owner. So, the solution is to simply do your incorporation in a different department. Perfectly legal and works fine.
My general perception is that if you remain goal oriented, Nicaragua is pretty easy to deal with. If, on the other hand, you want a concrete definition of how to do something which will always work, you will end up very frustrated. So, see this as flexibility others as a pain in the ass. The difference depends more on your attitude than anything else.
To offer a real world example, I know someone who told his lawyer that he wanted the the real purchase price he was paying for his property on the Compra-Venta. His lawyer explained that everyone puts a value significantly lower, virtually always an order of magnitude lower or more, on the paperwork. But, he is a black and white man and insisted.
When he went to pay the transfer taxes the government took the value he declared and doubled it. He protested. But, the government "knows" that number is always a lie and always doubles it.
Here is one more very common example. If the waiter in a restaurant asks "would you like a receipt" it is code for "would you like me to add the IVA (sales tax) to your bill.
Welcome to Nicaragua.
