What is a codicil to a will? It’s a formal legal amendment: a separate document that changes one or more provisions of your existing will without replacing the whole thing. If something in your estate plan no longer fits your life, a codicil lets you update it while leaving everything else intact.
That’s the basic answer. In Louisiana, there’s more to it.
Louisiana is a civil law state with succession rules that exist nowhere else in the country. Those rules affect how a codicil works, when it makes sense, and what can quietly go wrong if it isn’t drafted correctly. What follows is a plain-English explanation of the whole picture.
What a Codicil to a Will Actually Does
A codicil attaches to your original will, references it by date, and spells out exactly what is changing. Everything not mentioned in the codicil stays in effect as written in the original. When the two documents are read together, they function as a single instrument.
Common reasons people execute a codicil to a will:
- Changing the executor named in the original
- Adding or removing a specific bequest
- Updating a beneficiary after a divorce or a death in the family
- Providing for a child born or adopted after the original will was drafted
- Adding a charitable gift that wasn’t part of the original plan
These are the situations where a codicil earns its place. The change is limited, the original document is otherwise solid, and drafting a whole new will would be unnecessary time and expense.
What Louisiana Law Actually Requires
Louisiana’s execution requirements are stricter than any other state in the country, and this is where informal attempts most often fail.
To execute a valid codicil to a will in Louisiana, the document must be:
- A separate, written instrument, not handwritten changes in the margins of the original
- Signed by you in front of two witnesses and a notary public
- Drafted so it clearly cross-references the original will and identifies what is being changed
Louisiana is the only state that requires a notary for wills and codicils. A document that would hold up in Mississippi or Texas does not automatically meet Louisiana’s standard.
Handwritten changes, sticky notes, crossed-out lines, and informal letters have no legal effect on a Louisiana will. If you marked through a name in your original document and wrote in a different one, the original language still controls. The change does not exist in the eyes of the law.
This also means there is no shortcut when circumstances become urgent. Louisiana takes these formalities seriously because the stakes are serious. A codicil that isn’t properly executed can be challenged, and a successful challenge can unwind not just the amendment but the underlying will as well.
Codicil vs. New Will: Which Makes More Sense?
A codicil to a will works well when the change is narrow and clearly defined. One new executor. One different beneficiary for a specific asset. A single bequest to add. If you can describe what needs to change in a sentence or two, a codicil is probably the right tool. It costs less than drafting a new will, and the process is faster, often resolved in a single meeting.
A new will makes more sense when:
- Multiple provisions need updating at once
- Your family situation has changed substantially: remarriage, a blended family, the death of a spouse
- The original document is more than ten years old, and large portions no longer reflect your wishes
- You’ve already added one codicil and now find yourself needing to change something else
Multiple codicils layered on top of an old will create interpretation risk at the 22nd Judicial District Court. When a judge or your family has to reconcile provisions across three documents to figure out what you intended, the probability of dispute goes up. One current, well-drafted will eliminates that problem.
Charlton’s general rule: if the amendment touches more than two or three provisions, or if the original was drafted more than a decade ago, the cleaner path is usually a new will.
Forced Heirship: The Complication Most People Miss
If your estate involves children, forced heirship is the issue that deserves the most careful attention when amending a will in Louisiana.
Louisiana law protects the rights of forced heirs: children 23 years old or younger, and children of any age who are permanently incapable of self-care. These heirs are entitled to a guaranteed minimum share of your estate, called the legitime, regardless of what your will or any amendment to it says.
A codicil that inadvertently reduces a forced heir’s protected share, or that attempts to disinherit one without a legally recognized cause, can be challenged after your death. The amendment could be nullified, or the challenge could spill into scrutiny of the original will. Either outcome costs your family time and money in succession court.
What looks like a simple executor change on the surface sometimes touches beneficiary provisions in ways that matter when forced heirs are part of the picture. Charlton reviews every proposed amendment for forced heirship implications before anything is drafted.
When a Codicil to a Will Isn't the Right Tool at All
There are situations where neither a codicil nor a new will is the right answer, and knowing the difference matters.
If you transferred assets into a Revocable Living Trust, those assets pass outside your will entirely. A codicil to a will does not affect them. Trust amendments require a separate trust amendment document.
Retirement accounts, life insurance policies, and payable-on-death accounts pass directly to whoever is named as beneficiary on file at the financial institution, regardless of what your will says. If you want those assets to go to someone else, the fix is an update to your beneficiary designation at the institution, not a change to your will.
Charlton regularly encounters estates where the will is perfectly current, but a retirement account still lists an ex-spouse or a beneficiary who died years ago. Those mismatches cause real complications when succession opens. A codicil that doesn’t account for the full asset picture is only a partial solution.
How This Works in Practice with Charlton
When a client comes in wanting to make changes to an existing will, the conversation starts with two questions: what has changed, and how much of it? Those answers determine whether a codicil makes sense, whether a new will is the cleaner path, or whether the issue is actually with a trust or a beneficiary designation rather than the will itself.
If a codicil to a will is the right call, Charlton drafts it to meet Louisiana’s execution requirements, using language that avoids ambiguity and aligns with the original document. If a new will makes more sense, he walks through the full picture to ensure everything is captured correctly the first time.
Most amendment engagements are straightforward and resolve quickly. If the circumstances are more complicated than a one-clause fix can address, that initial conversation sometimes broadens into a fuller review. That’s not a pitch; it’s just what tends to surface when documents haven’t been touched in several years, and a lot of life has happened since.

Frequently Asked Questions
What is a codicil to a will, exactly?
A codicil is a formal legal document that amends your existing will. It attaches to the original, identifies what is being changed, and leaves everything else in place. In Louisiana, it must be signed before two witnesses and a notary public to be legally valid.
Does a codicil have to be notarized in Louisiana?
Yes. Louisiana is the only state in the country that requires a notary for wills and codicils. A codicil executed without one is not legally valid here, regardless of how clearly it states your intentions.
Can I just write in changes on my existing will?
No. Handwritten edits, crossed-out lines, and margin notes have no legal effect on a Louisiana will. To change a will in Louisiana, you need either a formally executed codicil or a new will entirely.
How many codicils can I add to a Louisiana will?
There’s no legal limit, but more is rarely better. Multiple amendments layered on a single original will create the risk of conflicting provisions and interpretation problems at succession. If you’re looking at a third amendment to the same document, a new will that consolidates everything is almost always the cleaner choice.
When does a codicil to a will make sense vs. writing a new will?
A codicil works well for narrow, isolated changes: one new executor, one updated beneficiary, one additional bequest. A new will makes more sense when multiple provisions need updating, when the original document is significantly outdated, or when the family situation has changed substantially since the original was drafted.
