I always advise people in your situation to seek the advice of an attorney to advise you based on the specific fact circumstances of your situation. Now, just based on what you've said, if you have been out of a lease for any period of time (even a single day) but still in possession of the premises, you are in what is called a "holdover tenancy". You say though that you have been in a holdover tenancy situation for over a year, and that you want to remind them that you "are not in a lease." Unfortunately, the law in Texas is that even if a lease does not contain a holdover provision (which we don't know whether yours does or not), if the tenant remains in possession and rent continues to be accepted by the landlord, the terms of the expired lease are presumed to continue unless there is an agreement to the contrary. Also, under the common law holdover rule, a landlord may elect to treat a tenant holding over as either a trespasser or as a tenant holding under the terms of the original lease. So, based on the limited information you've provided, you are still bound by the terms of your expired lease until you either sign a new agreement with the landlord, or terminate the holdover tenancy under the terms of the expired lease and then physically vacating the premises. Consult an attorney for your situation, and best of luck.
