Most landlords don't register however we can't work on that assumption.
Depends what you mean by 'work'.
Just go with the lady to the offices and ask for receits.
Yes, that is exactly what to do. If she decides to be difficult, well....
Do you mean "friendly" neighbour, Harry? Even the thought despises me. If you want to act act as yourself, don't use some dirty snitching.
I have no idea what you mean by " "friendly" neighbour". My point is that some landlords have a habit of trying to rip off their foreign tenants, and when somebody is trying to steal from you, they forfeit their rights to be treated like a normal person.
