My friends husband use as a cosigner for a apt lease without her knowledge and they use another name with the husband last name and thet want to get out of the lease what is the procedure to go tru this the landlord said that the husband can be out off the lease if the other tenant will find another cosigner is that true? Help

If the parties signed names which are not theirs to a legal document - in this case a lease, which is a contract - they have committed an illegal, criminal act.

I don't know what "cut off the lease" means.

Do they want to get out of the lease? The landlord has the right to sue them for the entire cost of the entire lease - when I say "them" I mean the people who did sign.

And, again, landlord could go to the Police with this. It is identity theft, an attempt to avoid rent and several other things, depending on the State.
