Must I Tell Beneficiaries About a Codicil

Emily just called, frantic. Her mother passed away last week, and Emily discovered a codicil to the will, handwritten and dated only three months before her mother’s death. It completely disinherited Emily’s brother, leaving everything to a new charity her mother had recently embraced. Emily fears her brother will challenge the codicil, and she wants to know if her mother should have told him about the change. The short answer is no, there’s no legal obligation to disclose a codicil during your lifetime. But the potential for family conflict and legal challenges makes it a far more nuanced issue than simply following the law.

What Happens if a Codicil is Contested?

A codicil is a legal document that amends an existing will. While seemingly simple, a codicil can be just as vulnerable to challenge as the will itself – and sometimes even more so. Common grounds for contesting a codicil include lack of testamentary capacity (the mother wasn’t of sound mind when she signed it), undue influence (the new charity somehow pressured her), or improper execution (it wasn’t signed and witnessed correctly). 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. The disruption and expense of litigation can be devastating, even for relatively small estates.

Is Transparency Always the Best Policy?

While legally permissible to keep a codicil secret, maintaining silence can severely damage family relationships. In Emily’s situation, her brother, blindsided by the disinheritance, is understandably upset. Had their mother openly discussed her intentions, even if difficult, it might have mitigated the shock and potential for a protracted legal battle. Some clients ask if proactively informing beneficiaries about a codicil creates an implied contract, potentially opening the door to claims of breach of contract if the estate isn’t distributed as discussed. While it could theoretically create a complex legal issue, the risk is usually outweighed by the benefits of transparency and family harmony.

What About Tax Implications and Estate Planning Updates?

Beyond disinheritance, codicils are often used to update beneficiaries, trustees, or specific bequests due to life changes. For example, a client might use a codicil to fund a trust for a grandchild’s education, or to adjust the distribution of assets after a significant market fluctuation. These updates can have substantial tax consequences, particularly regarding the step-up in basis. As a CPA as well as an attorney, I’m uniquely positioned to analyze these implications. Updating a will or codicil to accurately reflect current valuations minimizes potential capital gains taxes for your heirs. Also, it’s vital to review old will formulas in light of 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.

Protecting Digital Assets and Business Interests

Codicils aren’t just for tangible property. Increasingly, clients need to address digital assets—cryptocurrency, online accounts, and intellectual property—in their estate plans. 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. Similarly, if you own a business, a codicil can update ownership transfers or operating agreements. And be aware that 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.

The Validity of Handwritten Codicils

Some clients attempt to make quick changes with handwritten codicils. While handwritten codicils are valid in California 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. However, even a properly executed holographic codicil is more susceptible to challenge simply because it lacks the formality of a typed and witnessed document.

For over 35 years, I’ve guided families through these complex estate planning issues. My experience as both an Estate Planning Attorney and a CPA allows me to provide comprehensive advice, minimizing legal risks and maximizing financial benefits for your loved ones. Ultimately, the decision of whether to disclose a codicil is personal. But careful consideration of the potential legal and emotional consequences is crucial.

What makes a California will legally enforceable when it matters most?

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.

To distribute property effectively, you must define estate assets, clarify beneficiary roles, and understand how debts and taxes impact the final distribution.

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.
