The Care Act defines four areas where a person may find it difficult to be involved in the care and support planning or safeguarding processes. These are substantial difficulties in: understanding relevant information; retaining that information; using or weighing that information and communicating the person’s views, wishes or feelings (whether by talking, using sign language or any other means). Where a person has substantial difficulty in any of these areas, then they will need assistance from either an advocate or other person (such a family member) to be fully involved in the care and support processes.
