What's the difference between an LPA and a Will?

They cover different situations and you usually want both. An LPA covers what happens to your decisions while you're alive but can't make them — typically due to dementia, stroke, brain injury, or other capacity loss. A Will covers what happens to your estate after you die. An LPA stops being valid the moment the donor dies — at that point, the executors named in the Will take over. So the two documents fit together: the LPA handles the years (possibly decades) of living without capacity, the Will handles what happens after death. Most people want both. SAMEDAY LPA focuses specifically on LPAs — a Will is a separate document that you'd want to organise separately, ideally at the same time as your LPA.
