You do not always need to start over. If you want to make a small change to your will, a legal tool called a codicil lets you do that. But there are times when writing a new will makes more sense. The right answer depends on how much is changing and why.
What Is a Codicil?
A codicil is a legal paper that amends your current will. It must point to the original will and clearly state what is being changed. Under state law, a codicil must be signed and witnessed with the same care as the will itself. In Arizona, that means two witnesses. Ideally, it should also include a notarized statement to make it self-proving.
You can use a codicil to update a beneficiary (the person who gets your assets). You can change the person named as your personal representative. Or you can adjust a certain gift. If the rest of your will still fits your wishes, a codicil handles the job fast and at lower cost.
When to Add a Codicil
A codicil works best for simple, standalone changes. Common cases include:
- Changing who gets a certain item or dollar amount
- Naming a new personal rep or backup rep
- Adding or removing a small gift
- Fixing a minor error, like a wrong name or address
If you are making just one or two small tweaks, a codicil is the right tool. Simple as that.
When to Write a New Will
A new will makes more sense when the changes are big or when you have many updates. Common triggers include:
- Getting married or divorced
- The birth or adoption of a child
- A major change in what you own
- You want to reshape how your assets are split up
- Your named personal rep can no longer serve
If you try to stack several codicils onto one will, you create a mess of papers. Codicils can clash with each other. They can cause confusion. A new will wraps everything into one clean paper.
Risks of Making Changes the Wrong Way
Some people try to write changes by hand right on their will. Crossing out a name and writing in a new one does not work. Those changes are not legally valid. They can even raise doubts about the whole paper.
If a codicil is not signed and witnessed the right way, it can be thrown out. If more than one codicil exists and they clash, the court must guess which one you meant. That guessing can lead to results no one wanted.
How Codicils and New Wills Fit Into Estate Planning
Whether you add a codicil or write a new will, the goal is the same. You want a paper that clearly states who gets what. It should name who is in charge. And it should say what happens if your first choices are not around. An estate planning attorney can review your current will and tell you which option fits.
For a single, simple update, a codicil works well. For anything bigger, a fresh will gives you a clean start. Either way, the paper must be properly signed and witnessed. Skipping that step is the one mistake that can undo everything.
