What personal data am I obliged to provide?

Questioner

My 23-year-old son has accepted a room in Rotterdam, where he has now also moved in. He moved within Rotterdam, where he had another room. He has now received the concept contract, which states that his parents must act as guarantor, otherwise it will not go ahead. Despite the fact that he has a good job, only no permanent contract. It is not clear, but it seems that we not only have to act as guarantor for the rent, but also for any damage. There is no maximum amount linked to this. This does not seem right to me, and I get the feeling that I am signing a blank check. The landlord also asks for our personal details. In addition to the usual details such as name, address, age, they also want to know: employer, bank account number and BSN number, with a copy of the passport. It seems to me that providing all this information is susceptible to fraud. I would like to hear from you what I should and should not provide. In addition, my son is not allowed to register with the municipality at the address in question, because the space he rents has an office destination (half of the residents in the building rent such an office space). He must then register again at my address in another municipality. According to the landlord, this is legal, but I have my doubts about that.

Lawyer

Dear, This is a murky situation. Especially, everything that is requested by the landlord. This concerns a residence with full risk payment, renting a room without registration. As a rule, the guarantor is responsible for all rental debts and possible damage to the property/room. This with substantial amounts as a deposit and rental payment, as well as administration costs. If desired, I would like to review the rental contract for you to provide you with further information. You may also contact me directly. Hereby.
