Without prejudice to section 317, the disclaimer of any property in a dwelling house 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 in occupation of or claiming a right to occupy the dwelling house and either—
no application under section 320 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 section was served, or
where such an application has been made, the court directs that the disclaimer is to take effect.
