It is easy to give any address from any relative or from any friend for making any extra account at google adsense but I have doubt that will google adsense ask for any verification documents to check that this address is my own or not.

The other question is that can I use two different names and a single address for making multiple accounts. Suppose if one account is from me and the other is for my brother and we both give the same address as we both live in same home.
