Grace just received a devastating phone call. After her mother passed away, the attorney handling probate discovered a critical typo in the original will – a misspelled beneficiary name. Now, a simple correction could have prevented years of litigation, but because of the error, the court may invalidate that portion of the will, potentially distributing assets according to outdated intestacy laws. This oversight could cost Grace’s family tens of thousands of dollars in legal fees and lost inheritance.
Many clients believe a minor spelling error in a will is a trivial matter, easily overlooked. However, even seemingly insignificant mistakes can create significant problems during probate, leading to delays, increased expenses, and unintended consequences. A codicil is the standard method for correcting errors, but it must be executed with the same formality as the original will. What happens if that codicil itself has issues?
What Happens When a Will Contains Errors?

Errors in a will, even typographical ones, can open the door to legal challenges. While a court may overlook obvious clerical errors if the intent is clear, ambiguities arising from misspellings or inconsistencies can be grounds for a beneficiary to contest the document. This contest can significantly delay the probate process, drain estate assets with legal fees, and ultimately result in a court imposing its own interpretation of the testator’s wishes – which may not align with what they actually intended.
The severity of the issue depends on the nature of the error. A simple misspelling of a beneficiary’s name might be corrected if their identity is still reasonably discernible. However, a more substantial error, such as an incorrect asset description or an unclear distribution scheme, could invalidate that specific provision of the will, potentially leading to a default distribution under state intestacy laws. If a codicil is invalidated, assets may force full probate; however, for deaths on or after April 1, 2025, estates under $208,850 (per CPC § 13100) may still qualify for simplified procedures. This limit is set until 2028.
How Can a Codicil Correct Mistakes?
A codicil is a legal document that amends an existing will. It allows you to make changes or corrections without completely rewriting the entire estate plan. To be valid, a codicil must meet the same requirements as the original will: it must be in writing, signed by the testator (the person making the will), and witnessed by two adults. The codicil should specifically identify the provisions of the will it intends to modify or revoke, and clearly state the corrected language.
However, a poorly drafted or improperly executed codicil can create more problems than it solves. If the codicil is ambiguous, conflicting with other provisions of the will, or fails to meet the legal requirements for execution, it can be challenged in court just like the original will. This is where meticulous attention to detail and expert legal counsel are crucial.
What About Errors in the Codicil Itself?
This is the scenario I see far too often. Clients attempt to self-correct, using online templates or outdated forms. They execute a codicil, only to discover it contains its own errors – a missing signature, an improperly completed witness statement, or ambiguous language. Now, you have not only the original will’s error but a flawed attempt to fix it. This exponentially increases the risk of a successful challenge. In California, handwritten codicils are valid under Probate Code 6111, but only if the signature and material provisions (who gets what) are in your own handwriting. No witnesses or notary are required for this specific format.
Protecting Your Estate from Tax Implications and Business Concerns
As both an Estate Planning Attorney and a CPA with over 35 years of experience, I emphasize the importance of considering the tax implications of any changes to your will or codicil. For example, changes to trust provisions can impact the step-up in basis of assets, affecting capital gains taxes for your heirs. Proper valuation of assets is also critical. We routinely handle these complex issues for our clients, ensuring their estate plans are both legally sound and tax-efficient.
Furthermore, if your estate includes a business or an LLC, any changes to the will or codicil must also address ownership transfers and potential liabilities. As of March 2025, FinCEN has exempted domestic U.S. LLCs from BOI reporting; however, foreign-registered entities in the U.S. still face mandatory filing requirements and potential penalties.
Don’t Forget Digital Assets
In today’s digital world, a comprehensive estate plan must also address digital assets – online accounts, cryptocurrency, and other electronic holdings. A standard codicil often fails to include the specific RUFADAA language (CPC § 870) required to bypass federal privacy laws, potentially leaving your heirs locked out of crypto-wallets and email accounts.
Finally, remember the 2026 ‘tax cliff’ was averted by the OBBBA, which permanently increased the Federal Estate Tax Exemption to $15 million per person effective Jan 1, 2026. Old formula clauses should be reviewed to ensure they don’t over-fund trusts under these new limits.
How do California courts decide whether a will reflects true intent or creates ambiguity?
In California, a last will and testament operates within a probate system that emphasizes intent, clarity, and procedural compliance. When properly drafted, a will does more than distribute property—it creates legally enforceable instructions that guide courts, fiduciaries, and beneficiaries through administration with fewer disputes and less uncertainty.
- Clarity: Avoid vague terms that trigger interpretation fights.
- Health: verify mental state at signing.
- Errors: check for codicils often.
When a will is drafted with California probate review in mind, it becomes a stabilizing roadmap rather than a source of conflict. Clear intent, proper authority, and compliant execution protect both families and estates.
