How do I evict someone who has alease from my house in memphis tn?

Depends on why you are evicting. I would suggest going to the local housing court to get the exact process. This site might help:

But generally you serve notice that you are terminating the tenancy. How much notice depends on the reason for terminating and local laws and what's written in the lease.

If the tenant doesn't vacate by the deadline, then you go to court for an eviction order. This will usually involve a hearing. After the hearing, an eviction order will be issued with a deadline for vacating. If the tenant still hasn't vacated, you need to hire a sheriff to physically remove them.

You give them notice of the reason for their default of the terms of the lease ( they have to have broken one of the conditions of the lease) The amount of time to give notice depends on what the default is, payment, illegal activity, and other conditions you may or may not have put into the lease.
