Tenant can’t pay rent so he plans to sublet

[Jem J.]

Hello BP,

I have a rental property with student renters. The lease is signed by all 3 of them and they split the monthly lease. The lease is a collective lease and not individual lease. One student informed me yesterday that he is studying abroad and his parent refused to pay the rent. He said he won’t be able to pay it by himself so he will sublet.  He is asking me what is the process for subletting? I am dumbfounded...the  lease states no subletting but I can’t take the chance to not have the full rent or to take another person without screening. If I say yes, then the responsibility falls on me as far as safety of the others. Any advice is appreciated. Thank you.
