The disclaimer of any property of a leasehold nature does not take effect unless a copy of the disclaimer has been served (so far as the trustee is aware of their addresses) on every person claiming under the bankrupt as underlessee or mortgagee and either—
no application under section 320 below is made with respect to the property before the end of the period of 14 days beginning with the day on which the last notice served under this subsection was served, or
where such an application has been made, the court directs that the disclaimer is to take effect.
Where the court gives a direction under subsection (1)(b) it may also, instead of or in addition to any order it makes under section 320, make such orders with respect to fixtures, tenant's improvements and other matters arising out of the lease as it thinks fit.
