When most people are considering estate planning and protecting their future, they focus on one thing: writing a Will. It’s a classic tick-box exercise. You write down who gets the house, who gets the savings, and maybe who looks after the kids. You sign it, put it in a drawer, and think, “Sorted. My family is fully protected.”
But here is a major estate planning reality check: A Will only protects your family after you die. It does absolutely nothing for you while you are still alive.
If you suffer a sudden illness, a bad accident, or cognitive decline, a Will cannot help you. To truly secure your life, your assets, and your family, you must combine your Will with a Lasting Power of Attorney (LPA). This is where mental capacity planning becomes vital for true incapacity protection.
Here is why these two legal documents are the ultimate power couple—and why having one without the other leaves a massive, dangerous gap in your security.
The Handover: Why They Must Work Together
Think of a Will and an LPA as runners in a relay race. They are designed to pass the baton smoothly from one to the other, covering different stages of your life and beyond in your estate planning.
- Your LPA is your lifetime bodyguard. It only operates while you are alive. If you lose the mental capacity to make your own decisions, your chosen “attorneys” step in to manage your bank accounts, pay your bills, and make medical choices for you.
- Your Will is your post-death shield. It only wakes up the exact moment you pass away.
This is where the handover happens: The very second you die, your LPAs instantly self-destruct. Your attorneys lose all legal power to touch your bank accounts or make decisions. At that exact moment, your Will takes over, and your named Executors step in to distribute your estate according to your wishes.
If you only have one of these documents in your estate planning, your relay team is missing a runner.
What are the Dangers of Having a Will but No LPA?
Let’s look at a common scenario. You have a professionally drafted Will. But tomorrow, you suffer a stroke or are involved in a serious car accident that leaves you temporarily or permanently incapacitated.
Because your Will has no power during your lifetime, your family faces immediate chaos and a decision vacuum :
- Locked Accounts: Banks will routinely freeze bank accounts—even joint ones in some circumstances—if they find out an account holder has lost mental capacity and there is no registered LPA in place.
- The Care Home Trap: Your spouse or partner has no automatic legal right to choose where you receive care, what medical treatments you undergo, or whether to sell your house to fund care fees.
- The Court of Protection Nightmare: To pay your mortgage or buy groceries, your family will have to apply to the Court of Protection for a “deputyship.” This process is incredibly stressful, takes many months, and can cost thousands of pounds in ongoing fees.
What are the Dangers of Having an LPA but not a Will?
Now, let’s look at the flip side. You have set up your LPAs, ensuring you are fully protected during your lifetime. But your estate planning is incomplete and you never get around to writing a Will.
When you pass away, your LPAs instantly expire. Because you died without a Will (known as dying “intestate”), your family faces a whole new set of hurdles :
- The Government Decides: Since you have no Will, the strict and rigid UK intestacy laws decide who gets your assets. Unmarried partners could inherit absolutely nothing, and your home could be split in ways you never wanted.
- No Guardians for Minor Children: If you are a parent and die without a Will, you have not legally appointed guardians for your children. The state will decide who raises them.
- Sideways Disinheritance: If you are married or remarried and leave everything to your spouse under intestacy laws, your children from a previous relationship could easily be disinherited entirely if your surviving partner later remarries.
Special Protection for Business Owners
If you run a business, combining these documents is even more critical. You need a specialized Business LPA alongside your Will.
If you are incapacitated without a Business LPA:
- The bank can freeze your corporate accounts.
- Your staff and suppliers cannot be paid.
- You cannot agree on dividend payments (which often make up the bulk of small business owners’ income).
A Business LPA keeps your company running while you are ill , while your Will (and potentially a trust structure) ensures that the value of your business and your Business Property Relief (BPR) tax benefits are passed down safely to the next generation when you are gone.
How to Protect Yourself Completely
Despite the high stakes, only 41% of UK adults currently have a Will , and far fewer have registered LPAs. Many people—especially those under 40—wrongly assume they are “too young” for this kind of planning. But illness and accidents do not care about your age.

Think of them as a relay team for your affairs. A Will is your post-death shield, ensuring your assets are distributed according to your wishes after you pass.
