When a person passes away, is the ownership of his/hers internet accounts such as email, Facebook, etc. inherited by the next of kin (or whoever is named in the will, if any) or reverted to internet service provider? Similarly, if the same internet account is used by two spouses, but the name on the account and the avatar correspond to the deceased, can the surviving spouse (who has all the credentials such as passwords) keep using the account?
Subject to the specific contract and the terms of the will
For example, at present, both Apple’s and Amazon’s contracts are terminated on the death of the user so they are not inheritable.
Facebook will delete or memorialize (freeze) an account at the request of the legal representative. Twitter will only deactivate an account but won’t delete it.
