No. A complete estate plan should consider what happens both during your lifetime and after your death.
Your will governs how your estate is administered when you die, but it does not authorise anyone to manage your finances or make decisions for you while you are alive. Lasting Powers of Attorney can appoint trusted people to make financial or health and welfare decisions if you lose the capacity to make those decisions yourself.
Lifetime estate planning may also include gifting, trust arrangements, tax planning, succession planning for a family business and reviewing how property or other assets are owned.
Considering lifetime and death planning together helps prevent gaps. For example, your will may contain clear instructions, but your family could still face difficulties if no one has authority to manage your affairs during a period of illness or incapacity.
