I don’t know where you got that information from, I am surprised to read it…., I have been doing conveyancing for many years and I understand that a proffesional lawyer MUST check documents like building license, bank guarantees, first occupation license, etc, etc. and obviouly make sure that you sign a fair contract for the buyer.
No matter which area of Spain you are buying in, your lawyer should check those documents in advance. checking all that in advance and being strict with the developer AND the agency avoids many future problems, I know by experience…
I hope this helps you understand what is our job , regards, and good luck,
