Multiple Tenants Problem

[Andrew Yu]

I have a rental with 2 tenants on lease. They were an engaged couple. But something happened, the girl moved out. Now the guy isn't paying November rent. I served 3 Day Notice to Pay Rent to him yesterday. In this case, when I file Writ of Possession, are both of them responsible? We never did any additional paperwork after the girl moved out. The guy just texted me saying he wanted to stay and continue paying rent. I acknowledged... Should I go after the girl for the rent too? The lease isn't expired until May next year
