Lease Renewal - Cosigner Signature Required? Massachusetts

[Anthony Sherman]

Hello all,

We have a young couple as a great tenant who is looking to renew.  One of them is in college and her parent is on the original lease as a cosigner.  I have searched through the forums, MA law, etc. but cannot get a clear answer.  

Does anyone have experience in this process?  Specifically in Mass, but all input is welcome!

If anyone is aware of a clause in the MA rental laws that addresses this, linking it would be most appreciated!

Thanks!

Anthony
