As moderators we can only deal with queries laid down by the site owner which are listed underneath the forum name :
Share questions and results for DLA & ESA claim forms, medicals and appeals. PLEASE NOTE: this forum is provided as a courtesy for members to share experiences, we don’t guarantee an answer to your query.
Therefore, I'm locking this thread as it is not within our remit, plus the original post is nearly two years old.
I will say that it's not uncommon for the DWP to make mistakes when a claimant dies, or to inform relatives that a claimant is dead, when they are very much alive.
