Can I Modify My Trust After Signing

I recently met with Emily, a woman devastated because a handwritten codicil to her trust—altering who received her antique jewelry—was deemed invalid. She’d made the changes after a falling out with her niece, the original beneficiary, and attempted to simply attach the codicil to the trust document. Unfortunately, California law is incredibly strict about trust amendments, and a minor deviation from the formal requirements can render those changes worthless, costing her estate thousands in litigation and ultimately distributing the jewelry to the niece she intended to exclude.

What Happens If I Try to Change My Trust Incorrectly?

Emily’s situation highlights a critical point: Trusts, unlike Wills, are generally more difficult to modify once executed. While a Will can be amended with a codicil, a Trust requires a more formal process. Simply writing notes on the original document, even with a signature, is usually insufficient. The amendment must adhere to the same rigorous execution standards as the original Trust—meaning signed in front of a notary and witnesses, and ideally prepared by legal counsel. If you attempt to alter your Trust without following these procedures, the changes are likely unenforceable. If a Trust is invalidated, assets fall under intestacy; however, for deaths on or after April 1, 2025, estates with personal property under $208,850 (per CPC § 13100) may still bypass full probate via affidavit.

Are There Different Ways to Modify a Trust?

There are several accepted methods for altering a Trust. The most common is an Amendment, a separate document that specifically details the changes you wish to make. This Amendment must be executed with the same formalities as the original Trust. Another option is a Restatement, which essentially replaces the entire original Trust document with a revised version. This is often used when there are numerous changes. It’s also possible to create a new Trust entirely, transferring assets from the old one to the new—though this can have significant tax implications. As a CPA as well as an attorney with over 35 years of experience, I can help you navigate these tax considerations, particularly the potential impact on the step-up in basis for inherited assets and minimizing capital gains.

What About Digital Assets in My Trust?

Many of my clients are concerned about digital assets. Ensuring your trustee has the authority to manage these is crucial. Effective 2025, California law (CPC § 871) was expanded to grant fiduciaries power over digital accounts; however, you must still grant explicit RUFADAA powers in your Will or Trust to bypass federal privacy blocks. This wasn’t always the case, and older Trusts often lack these critical provisions. We can amend your Trust to include the necessary language to protect your digital legacy.

Can a Beneficiary Witness My Trust Amendment?

This is a common question, and the answer is often problematic. California Probate Code § 6112 states that an ‘interested witness’ (a beneficiary) triggers a legal presumption of duress or fraud. Unless there are two other disinterested witnesses, the beneficiary may lose their gift, taking only what they would have received under intestacy rules. It’s best to always use neutral witnesses who aren’t beneficiaries to avoid this legal challenge. It’s not worth the risk of invalidating the amendment, or even the entire Trust.

What If I Made a Small Mistake in the Signing?

Occasionally, a minor error occurs during the signing process – a misplaced signature, a missing date. Probate Code § 6110(c)(2) states that the court may validate a signature-defective Will if there is ‘clear and convincing evidence’ of the testator’s intent; however, this requires a costly court petition and is not a guaranteed safety net. Don’t rely on this provision; prevention is far better than cure. It’s much more efficient and cost-effective to ensure the document is executed correctly from the outset. Also, including a self-proving affidavit allows the Will to be admitted to probate without the testimony of the subscribing witnesses, significantly accelerating the court’s approval process, as outlined in Probate Code § 8220.

While California allowed temporary remote witnessing during the pandemic, the law (CPC § 6110) has reverted to requiring strict simultaneous presence; remote signatures are generally invalid for Wills unless they meet the narrow ‘Electronic Will’ standards of AB 298.

What standards do California judges use to determine a will’s true meaning?

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.

To ensure the will functions as intended, the executor must understand their fiduciary obligations, while the family should be prepared for the court supervision required to enforce the document.

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.
