The Pitfalls of Using AI to Write Your Will

Artificial intelligence has quickly become a tool for writing everything from emails to business plans. It can summarise research, generate ideas, and even draft legal-sounding documents in seconds. With that convenience, it may be tempting to ask an AI to write something as important as your will.

But when it comes to deciding what happens to your assets, your family, and your wishes after you die, relying on AI alone can create serious problems. Here’s why using AI to write a will is a risk to you and your family.

1. Wills Must Follow Specific Legal Requirements

The UK have strict rules about what makes a will legally valid. These rules may include:

• How the will must be signed

• The number of witnesses required

• Who can act as a witness

• What language must be included

• Whether the will must be dated

AI can provide general information, but it cannot reliably ensure your will complies with the exact laws in your jurisdiction. Even a small technical mistake could make the will partially or entirely invalid.

It has been reported in particular in many cases of Wills being written with AI that the witnessing has been done incorrectly, therefore invalidating the Will.

2. Your Situation Is More Complex Than a Template

Most people’s lives involve complexities that generic documents don’t handle well, such as:

• Blended families

• Stepchildren or adopted children

• Pets

• Overseas property

• Business ownership

• Trusts for minors

• Tax considerations

AI often generates documents based on patterns from general examples. It may not identify legal risks unique to your circumstances. A solicitor, however, asks detailed questions to uncover issues you might not have even considered.

3. Ambiguous Language Can Cause Family Disputes

One of the biggest reasons wills end up in court is unclear wording.

AI can produce text that sounds formal but is legally ambiguous. For example, phrases like:

• “My belongings should be shared fairly”

• “My house should go to my family”

These statements leave room for interpretation. Lawyers draft wills carefully to avoid misunderstandings and prevent disputes between heirs.

Poor wording could result in family members arguing over your intentions—sometimes for years.

4. AI Cannot Provide Legal Advice

AI tools generate information, but they cannot provide professional legal advice tailored to you.

A qualified solicitor can:

• Explain inheritance tax implications

• Suggest ways to protect vulnerable beneficiaries

• Help structure trusts for children

• Ensure your estate plan works with your financial situation

AI cannot replace this expertise or responsibility.

5. There Is No Accountability

If an AI-generated will causes legal issues after your death, there is no one responsible for fixing the problem.

When you work with a legal professional, you benefit from:

• Professional standards

• Legal liability

• Insurance protections

• Accountability

With AI, the responsibility falls entirely on you.

6. The Cost of Mistakes Is Much Higher Than the Cost of a Will

People often turn to AI to save money. But the cost of correcting a poorly written will can be enormous.

Possible consequences include:

• Your estate going through lengthy court proceedings

• Assets being distributed in ways you never intended

• Higher inheritance taxes

• Family conflicts that could have been avoided

A properly drafted will is relatively inexpensive compared to the financial and emotional cost of getting it wrong.  As well as the actual cost of litigation and Court time.

The Smarter Way to Use AI

AI can still be useful in the estate planning process. For example, it can help you:

• Create a list of your assets

• Organise questions to ask a solicitor

• Understand basic inheritance concepts

But it should be a starting point—not the final step.

Final Thoughts

Your will is one of the most important legal documents you will ever create. It determines how your life’s work is distributed and how your loved ones are cared for after you’re gone.

While AI is powerful, it isn’t a substitute for qualified legal advice. When it comes to something this important, a trained professional is worth the investment.
