Renters Insurance Requirements

[Nicholas Sanchez]

Hello!

I was asked this question from a friend who is renting, so I told him that I would try to get some info. He currently has renters insurance and is living in Minneapolis until July 31. He will be moving in with girlfriend on this date; however, she will be moving into the new place in Madison starting June 1 (i.e. two months prior to him officially moving). They have both signed lease and the landlord asked for proof of insurance. 

So, my question. If he already has renters insurance through current home in Minneapolis (and will not be officially moved into Madison until July 31), does he need to have insurance on both homes during this two month window where the lease will overlap? Or is it sufficient for his girlfriend to have insurance on the Madison home and then he can update the address when he moves in on July 31? 

Any help is appreciated!
