Section 25

Where rent due by any tenant, otherwise than for a term certain to a landlord thereof has remained unpaid for not less than 14 days after payment thereof became due and still remains unpaid, then, in the absence of an express agreement between the parties to the contrary, any notice to quit given by the landlord to the tenant shall, if the length thereof be otherwise sufficient, expire on such day as may by the terms of the notice be appointed for the expiration thereof, whether such day coincides with the termination of some period of the tenancy or not.
