Hi I recently signed a lease in a 2 bedroom 1 bathroom apartment in Somerville. I was taking over the lease from the previous tenant who was leaving the apartment so myself and the other roommate who was already living there and planned on continuing to live there both signed this new lease together with our names both on it. That being said, about three days after we signed this new lease together the roommate pulled out and found a new roommate to take over her room. I never signed a new/different lease with this new roommate. However, the broker sent over an updated lease where it looks like he copied and pasted my electronic signature/name from the old lease with the initial roommate onto this new lease that the new roommate had signed. Is this legal? If not, am I able to break this lease without penalties?
