Options Available When a Yahoo Account Owner Passes Away
Although Google may grant access to the contents of a deceased user’s account in some instances, Yahoo, on the other hand, will not.
If you need to contact Yahoo about a deceased user’s account, you can do so by mail, fax or email including a request letter, the Yahoo ID of the deceased user, proof that you have been authorized to act as the personal representative of the deceased and a copy of the death certificate.
