Avoid These Common Mistakes When Writing Your Own Will
Writing a will is one of the most important things you can do to protect your loved ones and your estate. Yet, many people in the UK attempt to write their own wills (often using templates or online tools) only to discover later that something vital was missed or worded incorrectly.
At Coastal Legacy, we’ve seen how small mistakes can cause big problems. Here are the most common pitfalls to avoid when preparing your will.
1. Not Signing or Witnessing the Will Correctly
For a will to be legally valid in England and Wales, it must be signed and witnessed properly.
This means:
- You must sign the will yourself.
- Two witnesses must be present when you sign it.
- They must also sign the document in your presence.
A will that’s not signed or witnessed correctly could be ruled invalid, leaving your estate to be handled under intestacy laws — meaning the state decides who inherits what.
2. Leaving Out Key Details
A will should clearly identify all assets, beneficiaries, and executors. Common oversights include:
- Forgetting to include bank accounts, pensions, or investments
- Failing to name all beneficiaries fully
- Omitting digital assets such as online accounts or cryptocurrency
Even small errors can lead to confusion, delays, or disputes between family members.
3. Using Ambiguous Language
Legal language might sound formal, but clarity is essential. Phrases like “I leave my savings to my children” can be misinterpreted if you have multiple accounts or complex family circumstances.
Professional will writers ensure your wishes are stated clearly and precisely, removing any risk of misunderstanding.
4. Forgetting to Name an Executor
An executor is the person responsible for carrying out your wishes. If you forget to appoint one, the courts may need to step in and assign someone, which can cause unnecessary stress and delay.
Most people choose a trusted relative, friend, or professional to act as executor. Coastal Legacy can help you decide who’s most suitable based on your circumstances.
5. Failing to Update the Will
Life changes — your will should, too. Marriage, divorce, having children, or buying property are all good reasons to review your will.
An outdated will can cause just as many problems as not having one at all. Regularly reviewing it ensures your wishes still reflect your current life.
6. Not Getting Professional Advice
DIY wills may seem cheaper, but mistakes often go unnoticed until it’s too late. Professional will writers not only ensure everything is legally correct but also guide you through complex issues such as:
- Joint ownership of property
- Guardianship of children
- Tax implications and inheritance planning
The small cost of professional advice can save your loved ones time, money, and stress in the future.
