When does a general power of attorney (springing) end?
It ends at your death. You can’t give your attorney-in-fact/agent/donee authority to handle things after your death by way of a springing power of attorney (e.g. paying your debts, making funeral or burial arrangements or transferring your property to the people who inherit it). If you want your attorney-in-fact/agent/donee to have the authority to wind up your affairs after your death, use a will to name that person as your executor.
