A codicil is a legal term you might hear in discussions about wills, estates, or inheritance, but many people aren’t sure what it actually means. In simple terms, a codicil is an official document used to make changes or additions to an existing will without rewriting the entire document. Understanding what a codicil is—and how it’s used—is essential for anyone planning their estate or managing legal matters related to inheritance. Updated for 2026, this guide will explain the codicil meaning, provide practical examples, and explore the contexts in which it’s commonly used, helping you navigate this legal tool with confidence.
What Does “Codicil” Mean? (Definition & Origin)
A codicil is a legal document that modifies, adds to, or revokes parts of an existing will without replacing the entire will. Think of it as an amendment or a legal “update” to a previously written will.
Origin of the Word
The word codicil comes from the Latin word codicillus, which means “a small writing” or “note.” Historically, codicils allowed individuals to make changes to their wills without rewriting the entire document—an essential convenience before digital word processors existed.
Key Points About Codicils:
- They are legally binding when properly executed.
- They must reference the original will.
- They can add, delete, or clarify instructions in a will.
How to Use “Codicil” in Legal Contexts
Using a codicil might seem complicated, but it’s actually straightforward if you follow these steps:
- Reference Your Original Will
A codicil must clearly mention which will it is modifying. - Specify the Changes
Be precise—state exactly what part of the will you are changing or adding. - Sign and Witness
Like your will, a codicil requires your signature and usually at least two witnesses to be legally valid. - Keep It With Your Will
Store the codicil together with the original will to avoid confusion.
Pro Tip: In 2026, many people also register digital codicils with online estate planning platforms to ensure they’re recognized legally.
Examples of “Codicil” in Conversations
To make the codicil meaning crystal clear, here are a few real-life scenarios:
Example 1:
Mom added a codicil to her will so that her favorite niece gets the antique necklace she always admired.
Example 2:
If you’re updating your estate plan, consider whether you need a codicil or a completely new will.
Example 3:
He drafted a codicil to include his new property after buying a vacation home last year.
These examples show how codicils are used to adjust existing instructions without rewriting the whole will—a practical solution for ongoing life changes.
Common Mistakes or Misunderstandings
Even though a codicil is a useful legal tool, people often misuse it. Here’s what to watch out for:
- Mistaking a Codicil for a Will
A codicil cannot stand alone; it always modifies an existing will. - Not Signing or Witnessing Properly
Missing signatures or witnesses can make a codicil invalid. - Losing Track of the Original Will
If the codicil is separated from the will, its instructions may be ignored. - Overcomplicating Changes
Some changes are so extensive that drafting a new will is simpler than adding a codicil.
Related Legal Terms and Abbreviations
Understanding codicil in context is easier if you know some related terms:
- Will/Testament – The main document outlining your final wishes.
- Executor – The person responsible for carrying out the instructions in a will or codicil.
- Trust – A legal arrangement for managing assets, often referenced in wills.
- Bequest/Legacy – A gift left to someone in a will.
Tip: If you’re familiar with online legal tools or estate planning apps, you might also see abbreviations like POA (Power of Attorney) and PDF codicil forms—these are often digital equivalents of the traditional paper codicil.
Why Codicils Are Still Relevant in 2026
Even with digital estate planning tools, codicils remain a convenient, legally recognized way to update your will without rewriting everything. They’re especially helpful if you:
- Acquire new assets
- Add or remove beneficiaries
- Want to make minor corrections
for 2026, codicils can now even be drafted, signed, and stored digitally in some jurisdictions—making them faster and safer than ever.
Conclusion

Understanding its meaning and proper use can save time, prevent confusion, and ensure your wishes are clearly documented. Whether you’re making minor adjustments, adding new beneficiaries, or correcting details, a codicil helps keep your estate planning flexible and up-to-date.
