The review needs a traceable link between the will and the care history. Secure the original or a complete copy of the will, codicils, messages, care notes, medical and support appointments, expense records and statements by people who observed the daily situation.
Arrange the records chronologically. Record when care began, which tasks were agreed or expected, when the health situation changed and whether another arrangement was discussed. The care obligation must be kept separate from a care legacy and from a claim for equalisation for care already provided.
