Couple I support: wife on max PIP for multiple conditions including CFS, pain requiring regular Tramadol, mh issues, etc. Previously working and caring husband develops drastic life threatening form of cancer. So due to wife's inability to deal with paperwork on top of now her caring for husband, supporting him at many frequent appointments, managing his multiple medications etc [he is severely dyslexic] despite own fatigue, the UC claim was not submitted for several months after he became unable to work. If the dire circumstances justify requesting a backdating eg to coincide with when he finished work [of course morally they do but we are dealing with the DWP...], what is the best way to present this please? The UC journal award notice does say the backdating date [currently to when the claim was finally submitted] can be challenged. But gives no further details on doing so. Many thanks for any help.
