Texas Property Code - PROP § 82.056. Leasehold Condominiums

(a) Any lease the expiration or termination of which may terminate the condominium or reduce its size must be recorded.  The lessor shall sign the declaration, and the declaration must state:

(b) After the declaration for a leasehold condominium is recorded, neither the lessor nor the lessor's successor in interest may terminate the leasehold interest of a unit owner who makes timely payment of the unit owner's share of the rent and otherwise complies with all covenants that, if violated, would entitle the lessor to terminate the lease.  A unit owner's leasehold interest is not affected by failure of any other person to pay rent or fulfill any other covenant.

(c) Acquisition of the leasehold interest of a unit owner by the owner of the reversion or remainder does not merge the leasehold and fee simple interests unless the leasehold interests of all unit owners subject to that reversion or remainder are acquired.

(d) If the expiration or termination of a lease decreases the number of units in a condominium, the allocated interests shall be reallocated as though those units had been taken by condemnation unless otherwise provided by the declaration.  Reallocation shall be confirmed by an amendment to the declaration prepared, executed, and recorded by the association.
