(a) Every person in possession of land out of which any rent is due, whether it was originally demised in fee, or for any other estate or freehold, or for any term of years, shall be liable for the amount of proportion of rent due from the land in his possession, although it is only a part of what was originally demised.
(b) Such rent may be recovered in an action, and the deed or demise, or any other instrument in writing, if any, showing the provisions of the lease, may be used in evidence by either party to prove the amount due from the defendant.
(c) Nothing contained in this section shall deprive landlords of any other legal remedy for the recovery of their rents, whether secured to them by their leases or provided by law.
