Lasting Power of Attorney vs Deputyship — Which Do You Need?

The differences between a Lasting Power of Attorney and a Court of Protection Deputyship, when you need each, costs, and how to set them up.

By PocketWise · · 4 min read

If you lose the ability to make your own decisions — through illness, accident, or age — someone needs legal authority to act for you. The two routes are a Lasting Power of Attorney (set up in advance) and a Deputyship (arranged after the fact). Setting up an LPA while you can is far easier, cheaper, and gives you control.
