Brierley. John Robert, otherwise Robert, otherwise Joseph, of 258 Ridgway Street East, Manchester, died on 15 August 1974. Administration granted 9 September. £2827.
You could apply for a copy of the Letters of Administration which might have been granted to a family member, or perhaps a firm of solicitors. Letters of Administration are issued when there is no valid will, or one not able to be executed. The estate is then distributed in accordance with criteria laid down in law.
