Hey! You do understand that there are rules for the building, right? There are also a law that says you must have a rental contract for minimum 30 days for every tenant. The documents she ask for is all about that, and you are bound by law to provide them. If you do not do, she will change code, which is also well within her rights, for protecting other owners and residents as well as upholding both the rules of the internal rules that you have signed as well as the laws of Thailand.
So, at the end it IS her damn business and you will be the one standing with a long nose with tenants having to leave your god damn condo.
