Service of copy of notice of disclaimer on interested persons
69.—(1)  The trustee of a bankrupt’s estate disclaiming any onerous property must, within 14 days after the date of the notice of disclaimer, serve a copy of the notice to —
(a)in a case where the property is an unprofitable contract under section 373(2)(a) of the Act — any person who, to the trustee’s knowledge, is a party to the contract or has an interest under the contract;
(b)in a case where the property is of a leasehold nature mentioned in section 374 of the Act — any person who is claiming under the bankrupt as sub-lessee or mortgagee mentioned in section 374(1) of the Act; and
(c)in any case — any person who (to the trustee’s knowledge) —
(i)claims an interest in the disclaimed property; or
(ii)is under a liability in respect of the disclaimed property, not being a liability discharged by the disclaimer.
(2)  If subsequently, it comes to the trustee’s knowledge that any person has such an interest in the disclaimed property that would have entitled the person to receive a copy of the notice of disclaimer under paragraph (1), the trustee must then as soon as reasonably practicable serve on that person a copy of the notice.
