Lasting Power of Attorney or also known as LPA in short, is a legal document or deed which we crafted with our client to suit his or her needs to prepare them for the day if they were to lose their mental capacity to make decisions. To create their own LPA, client must be at least 21 years of age. LPA involves voluntarily appointment of one or more persons to make decisions and act on client behalf when they lose their mental capacity to make decisions.
