The Hidden Risks of an Outdated Will
Many people take the important step of making a will and then file it away and never revisit it again. It’s easy to think of a will as a “one-time job” that will stand for life. But in reality, life is rarely static. Families grow, relationships change, assets shift, and unexpected events happen.
If your will isn’t updated to reflect those changes, it can cause serious problems. In some cases, outdated wills can lead to unintended heirs inheriting everything, loved ones being excluded, and lengthy disputes between family members.
At Town & Country Law, our experienced legal experts often see the consequences of outdated wills. This guide explores what happens if you don’t update your will after major life events, which situations demand a review, and how to protect your family from unnecessary stress.

Why Wills Must Be Reviewed Regularly
A will is not a static document. It is meant to reflect your personal circumstances and wishes at the time of your death. If you’ve had major life changes since writing your will, there’s a high chance it no longer reflects what you want.
Without updates, an old will may:
- Leave out new children or grandchildren.
- Still include an ex-spouse or estranged partner.
- Name executors who have since passed away or moved away.
- Fail to deal with new property or assets.
This is why experts recommend reviewing your will every few years or after key life events.

Life Events That Demand a Will Update
Below is a table that summarises common life events and their effect on wills.
| Life Event | Impact on Your Will | Action Needed |
|---|---|---|
| Marriage or Civil Partnership | Usually revokes an existing will unless made in contemplation of marriage | Create a new will immediately after marriage |
| Divorce or Separation | Ex-spouse may still inherit if not removed | Review and update to avoid unintended inheritance |
| Birth/Adoption of Children | New children may be excluded if not named | Add children or create trusts for them |
| Death of Beneficiary/Executor | Beneficiary/executor may no longer be alive | Update will to include replacements |
| Buying/Selling Property | Old property may be included, new property left unmentioned | Revise to reflect current assets |
| Inheriting Wealth | Significant changes in estate value | Update to distribute fairly and clearly |
| Moving Abroad or Foreign Property | UK will may not be recognised abroad | Consider additional local wills |
Marriage or Civil Partnership
Marriage is one of the most common reasons why wills are unintentionally revoked. Under UK law, getting married cancels your existing will unless the document was specifically written “in contemplation of marriage”.
This means that if you marry and forget to update your will, your spouse could automatically inherit everything and potentially leaving children from previous relationships without any protection.
Divorce or Separation
Divorce does not automatically cancel your will. Instead, the law treats your ex-spouse as though they died before you. That means they cannot inherit, but other unintended consequences may arise, such as leaving gaps in the distribution of your estate.
If you separate without divorcing, your ex-partner may still inherit under your will. This is a common source of disputes and is one of the most important reasons to update your will.

Birth or Adoption of Children or Grandchildren
Adding new family members changes your responsibilities. An outdated will may unintentionally exclude children or grandchildren who were born after it was written.
Updating your will ensures that all children are recognised and protected. For more complex family structures, you may wish to explore trusts — learn more in our Family Trusts Guide.
Death of a Beneficiary or Executor
If someone named in your will dies before you, it can cause legal uncertainty. For example, if your executor dies, who will manage your estate? If a beneficiary has died, who should receive their share?
Failing to update after these events can leave your estate partially intestate.
Buying or Selling Property
Property is usually the largest asset in an estate. If you buy a new property, especially abroad, or sell your main residence, your will may not match your current circumstances.
For guidance on international estates, read our blog on Foreign Property in a UK Will.
Receiving an Inheritance or New Assets
If you acquire significant new assets, your old will may not distribute them correctly. This can lead to unfair outcomes or disputes between family members.
Trusts can be a powerful way to manage inherited assets for future generations. Explore our Trust and Trustee Services for more details.
Common Mistakes People Make with Outdated Wills
Even people who take estate planning seriously can fall into traps with outdated wills. Some of the most common mistakes include:
- Assuming a will written decades ago still reflects their wishes.
- Forgetting to name backup executors.
- Overlooking digital assets such as email accounts, social media, or online banking.
- Using DIY will kits that don’t adapt to complex family changes.
- Not informing executors or beneficiaries about updates.
How Often Should You Review Your Will?
At Town & Country Law, we advise clients to review their wills every three to five years, or sooner if they experience major life changes.

FAQs
Does marriage cancel a will in the UK?
Yes. Marriage usually revokes your will unless it was written in contemplation of that marriage.
Can an ex-spouse inherit if I don’t update my will?
If you divorce, your ex is treated as though they died before you. However, this can create gaps in your estate plan. If you separate without divorcing, your ex may still inherit.
Do stepchildren inherit if not named in a will?
No. Stepchildren do not automatically inherit unless they are specifically included in your will.
How do I change executors in my will?
You must make an official amendment (codicil) or write a new will. It’s important to ensure this is legally valid.
Is a will still valid after 20 years?
Yes, but it may be badly outdated. Laws and your personal circumstances are likely to have changed.
