I have set up the legal documents of Lasting Power Of Attorney with my daughters, but I still have control. Once I no longer feel comfortable, the system is all set up ready for them. The worst bit of all the paperwork has been done. (Lasting Power of Attorney (LPA) is a legal document that lets you appoint one or more people to help you make decisions or to make decisions on your behalf if you cannot make your own decisions. This gives you more control over what happens to you.
