With a wealth of information available online and inexpensive template kits sold on the high street, it has never been easier to attempt a "Do-It-Yourself" Will.
For individuals with very straightforward circumstances, a DIY Will may appear to be a simple and cost-effective solution.
However, a Will is unique in that it is only ever tested when the person who created it has passed away. If errors exist in the wording, signing process, or structure, they may not come to light until it's too late to correct them.
When deciding between a DIY approach and professional Will drafting, the key difference is not just cost - it's the level of legal protection, clarity, and foresight built into the document.
The Unseen Complexities of DIY Wills
Writing a Will may appear straightforward, but UK estate law relies on strict formalities and precise interpretation.
Here are three of the most common areas where DIY Wills can create unintended problems.
1. Issues with the signing process (execution)
Even a well-written Will may not be valid if it is not signed and witnessed correctly.
Under UK law, a Will must be signed in the presence of two independent witnesses who are not beneficiaries.
Common mistakes include:
- Using a beneficiary as a witness
- Having witnesses sign at different times
- Not completing the signing process in the correct order
These errors may result in parts of the Will being challenged or disregarded during probate.
2. Ambiguous or unclear wording
DIY Will templates often rely on generic language that may not suit more complex family or financial situations.
Everyday wording can sometimes create uncertainty when interpreted during probate.
For example, unclear definitions of "personal possessions" or "estate" can lead to delays or disputes between beneficiaries if expectations differ.
3. Failure to plan for future life changes
A DIY Will is typically a snapshot of your circumstances at the time it's written.
It may not adequately account for:
- A beneficiary dying before you
- Marriage, divorce, or remarriage
- Changes in property ownership
- The arrival of grandchildren or blended family changes
These events can unintentionally alter how an estate is distributed.
What Does a Professional Will Writer Provide?
Many people assume the value of a professional Will writer is simply producing the final document.
In reality, the main value lies in the advice, structure, and safeguards built into the process.
Professional standards and accountability
As a member of a recognised professional body such as the Society of Will Writers (SWW), practitioners are expected to follow a formal Code of Practice and maintain ongoing professional development.
While Will writing is not regulated in the same way as solicitors, these professional standards help ensure consistency, ethical practice, and accountability.
Professional indemnity insurance protection
Professional Will writers typically carry Professional Indemnity Insurance, often up to £2.5 million.
This provides an additional layer of financial protection in the unlikely event of an administrative error or oversight during the drafting process.
In contrast, DIY Will kits do not offer any form of professional safeguard, meaning responsibility for any mistakes rests entirely with the individual and their estate.
Tailored advice for real-life family situations
The most significant difference between DIY and professional Will drafting is the advice process.
A professional Will writer will not simply record instructions, they will assess your overall circumstances, including:
- Blended family arrangements
- Property ownership structures
- Protection for vulnerable or young beneficiaries
- Whether trusts may be appropriate
- Potential future changes that could affect the Will
This allows the Will to be designed not just for today, but with future life events in mind.
Summary: Choosing the Right Approach for Your Family
A DIY Will may be suitable for very simple estates where wishes are straightforward and family circumstances are uncomplicated.
However, where there is property ownership, blended family structures, young beneficiaries, or a desire to ensure long-term control and clarity, professional drafting provides significantly greater structure and reassurance.
The key difference is not just how the Will is written, but how well it anticipates the realities of life after it's created.
