about this permit rule
Lawyers know chit,its the Notariusz.Just make sure you have your own Notariusz and not the one by the developer ...cuz just in case.Lawyers will just bleed zlots which you could save for dinners.Notariuz is the one who has to register your property in the gmina land register so he will not close if he/she cant.They will also check if there is a loan on the property.
lol just like your own lawyer and the developers lawyer have 2 diff opinions,dont waste money on em pigs in Poland.Go for the real deal:NOTARIUZ
Also an advice for Polish lawyers,before the meeting always ask them that you are meeting him for consultation or presentation.I dont meet a lawyer for consultation just for there presentation what they can do if I hire them.For consulations they ask you hundreds.presentations has to be free.
