I have recently set up a superannuation self trust deed which we have received two registered copies from our accountant. One registered copy has now gone missing in the mail when our settlement agency sent it back in the mail (not registered). Should we be concerned that a copy has gone missing in the mail???? We are worried the trust deeds may get in the wrong hands. Not sure what to do as we still retain our one and only copy. Any advise would be much appreciated as I don't know how valuable these trust deed documents are.
