When a LiveJournal user is reported as deceased, their account can be placed in "memorial" status. This disables future entries by the account, and disallows to comment on existing entries for users not included in author's Friends list. It also prevents the journal from being deleted for inactivity in the future.
Friends or relatives of a deceased LiveJournal user can send a support request
with subject "%username% acct memorial" specifying the username of the deceased. To prevent false memorial status requests, it is advisable to include additional facts which may be helpful to check the information about the decease such as social networks accounts addresses, links to discussions, news, etc. Members of the LiveJournal Customer Care Team will then carry out an internal examination and place the account in memorial status.
Regardless of relationship, for privacy reasons it is not possible for LiveJournal to grant access to a LiveJournal account or release the contents of any protected entries without a valid court order.
