Subject to the provisions of this section and section 48 below, the terms of the tenancy or joint tenancy to which a direction under section 39(5), (6) or (9) above entitles the person or persons concerned shall be the same as the terms on which the holding was let immediately before it ceased to be let under the contract of tenancy under which it was let at the date of death.
If on the date of death the holding was held by the deceased under a tenancy for a fixed term of years, subsection (1) above shall have effect as if the tenancy under which the holding was let at the date of death had before that date become a tenancy from year to year on (with that exception) the terms of the actual tenancy as far as applicable.
If the terms of the tenancy to which such a direction entitles the person or persons concerned would not, apart from this subsection, include a covenant by the tenant or each of the tenants not to assign, sub-let or part with possession of the holding or any part of it without the landlord's consent in writing, subsection (1) above shall have effect as if those terms included such a covenant.
