Thank you. Upon someones death, responsibility for that person's estate including assets and debts that may exist passed to that individual's executor named and their will, or if no will was made, to next of kin in a defined order of priority - e.g. spouse, child etc.
The executor or administrator has all the same rights that your neighbour would have had as against the company - no better and no worse. Accordingly they would have a legal right to return the items or require them to be repaired if for example the did not work properly. Also, they would have a legal right to return the hearing aids if there was any kind of moneyback guarantee as was the case here. Unfortunately, if the moneyback guarantee has expired, that right falls away.
Accordingly if the units are not defective, there would be no legal right to return the units despite the extenuating circumstances. It is of course open to the hearing a company to agree to accept the return despite having no legal obligation to do so though from what you say, they do not appear to be overly keen to do so. There is nothing preventing you continuing to pursue them for a definitive answer on this point though.
I am sorry this is not likely to be the Information you were hoping for but I hope at least it clarifies the legal position and this of some assistance in that respect.
