Is it Better to Make a Codicil or New Will

Emily just called, frantic. Her mother passed away last month, and Emily discovered a codicil to her mother’s will… dated after the original will. The problem? The codicil was improperly witnessed – one witness signed it on the same day the will was originally executed, not when the codicil was signed. Now, the entire estate is potentially heading for probate litigation, costing her thousands in legal fees and delaying the distribution of assets to the rightful beneficiaries. Emily’s situation highlights a common, costly mistake: assuming a codicil is a quick fix when a complete will replacement might be the safer route.

Many clients ask whether it’s simpler to amend an existing will with a codicil or draft a new one. There’s no one-size-fits-all answer, but several factors strongly favor rewriting the entire document. The first, as Emily’s case illustrates, is execution formality. A codicil must adhere to the same strict witnessing and notarization requirements as the original will. Even a minor error – a signature out of order, a witness who isn’t present during the signing, or an improperly completed attestation clause – can invalidate the entire codicil, potentially reverting to the terms of the original will or, in some cases, triggering intestacy (dying without a will).

The complexity of the changes you’re making is also crucial. A codicil is best suited for minor adjustments – changing an executor, updating a specific bequest, or adding a small beneficiary. If you’re significantly altering beneficiaries, adding substantial assets, or dealing with complex family dynamics (like a divorce or a new child), rewriting the entire will provides clarity and reduces the potential for ambiguity. Attempting to cram complex changes into a codicil can create internal inconsistencies, leading to future disputes.

What Happens if a Codicil is Invalidated?

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. A complete rewrite, while more work upfront, can preempt these issues entirely. Furthermore, consider the impact on blended families. Codicils often fail to adequately address the unique challenges of stepchildren or second marriages, potentially disinheriting intended heirs due to poorly drafted language or unforeseen circumstances.

How Do Tax Laws Affect Will Updates?

Tax laws are constantly evolving, and an outdated will can lead to unintended tax consequences. For example, 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. As a CPA as well as an estate planning attorney, I frequently encounter wills drafted years ago that rely on outdated exemption amounts, resulting in unnecessary estate taxes. A comprehensive review and rewrite can optimize your estate for current tax laws, preserving more assets for your beneficiaries.

What About LLCs and Business Ownership?

If you own a business, especially an LLC, updating your will requires extra care. 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. Your will should clearly outline how your business interests will be transferred, considering buy-sell agreements, succession plans, and potential tax implications. A codicil might not adequately address these complexities, potentially leaving your business vulnerable during a transition.

Don’t Forget Digital Assets

In today’s world, digital assets – cryptocurrency, online accounts, social media profiles – are often significant parts of an estate. 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. A properly drafted will should include specific provisions authorizing your executor to access and manage your digital assets, complying with both legal and technological requirements.

I’ve been practicing estate planning and tax law for over 35 years, and I’ve seen firsthand how seemingly small mistakes can lead to significant legal battles and financial losses. The cost of a complete will rewrite is often modest compared to the potential expenses of litigating a flawed codicil. A comprehensive estate plan isn’t just about distributing assets; it’s about providing peace of mind, protecting your family, and ensuring your wishes are carried out exactly as you intend. A new will allows for a fresh, holistic review of your entire estate, ensuring it aligns with your current circumstances, tax laws, and family dynamics.

• Consider the Complexity: Minor changes? Codicil. Major revisions? New Will.
• Check Execution: Ensure all signing and witnessing requirements are met.
• Account for Tax Laws: Review for current federal and state tax implications.
• Address Business Interests: Outline transfer of ownership and succession plans.
• Include Digital Assets: Specify access and management of online accounts.

What does a California probate court look for when interpreting testamentary intent?

In California, a last will and testament is reviewed under probate standards that focus on intent, capacity, and execution. Clear drafting reduces ambiguity, limits misinterpretation, and helps families avoid unnecessary conflict during estate administration.

For California residents, understanding how intent, authority, and compliance interact is one of the most effective ways to protect family harmony and estate integrity. A will that anticipates probate scrutiny is far more likely to be honored as written and far less likely to become the source of unnecessary conflict.
