Law / Temporary residence in Poland (registration, legal title for apartment) [5]

Hi! I'm an SGH student and I have a question for the people that applied to temporary residence. All the documents make sense to me except the following:

-Confirmation of registration for temporary residence
-Legal title to the apartment

Anyone has some experience on how to prepare these documents? I'm renting a studio so the owner can help me. I just need to tell him what I need. I have a 1 year national visa, so I'm not in a hurry, but nevertheless it's better for me to have. a resident permit because I get more rights.

From what I read, for the confirmation of residence, I need to go with the landlord to the local town hall. Is that right? how much does this document cost? what about the legal title to the apartment?

Regards
