I live in Los Angeles and have been unable to resolve issues with my roommate who is not on the lease. I have lived on this property for many years and am now on a month to month lease. My roommate has paid rent directly to the landlord and has some utilities in his name, but is not on the lease as the agreement is in my name. I have asked him to leave, but he is not agreeing. My landlord doesn't want to be involved.

From what I understand, I basically became his landlord as I am the one who is responsible per the original lease. I am willing to give him 60 days to find alternate living arrangements as he has been here for over a year. I just want to make sure I am interpreting things correctly before I proceed further.

Thank you so much!

The part that confuses me, is that he pays directly to the landlord, which gives him a basic verbal rental agreement with the landlord not you.
So has the landlord basically rented the same place to two people?

This would be my defense if I was him and went to court, and I wuld show where I paid the landlord ( not you) and that the landlord is not evicting me.

Who found this renter, who made the rental agreement with him, and why is he paying the landlord not you

Now yes the way you stated is how it should work

I was living between NY and LA for a while for work, so I brought him in to stay in the extra room to help supplement the rent when I was out of town. I also did not want to give the place up. The landlord stated that he didn't want a new lease as he would have to go up on th rent and didn't know my friend at the time.

To make it simpler while out of town, he made deposits directly in to the landlord's account, although the rental agreement was made in my name several years before I brought him in.

Your roommate actually has a written agreement with the landlord if he has paid by check/money order etc. I would go to housing authority website
