Pertinent
58-2504. Termination of tenancy
at will; notice. Thirty days' notice
in writing is necessary to be given
by either party before he or she can
terminate a tenancy at will, or from
one period to another of three months
or less; but where in any case rent
is reserved payable at intervals of
less than thirty days, the length of
notice need not be greater than such
interval between the days of payment:
Provided, however, That when premises
are furnished or let by an employer
to an employee, said tenancy shall
cease and determine ten days after
written notice to vacate: Provided
further, That not more than fifteen
(15) days' notice in writing by a
tenant shall be necessary to
terminate any tenancy as described in
this section of persons in the
military service of the United States
in which the termination of tenancy
is necessitated by military orders.
