What is the 120day survival rule for inheritance

Emily called, frantic. Her mother, Beatrice, passed unexpectedly last month, and Emily discovered a codicil – a change to Beatrice’s Will – leaving a cherished antique necklace to Emily’s sister, Clara. The problem? The codicil was dated just 118 days before Beatrice’s death. Emily fears Clara will be denied the gift, and rightfully so. California law, specifically Section 6110 of the Probate Code, dictates a strict 120-day rule for testamentary changes. A codicil, or even an entirely new Will, executed within 120 days of the testator’s death creates a rebuttable presumption of undue influence.

This isn’t an automatic disqualification, but it throws the entire inheritance into potential legal jeopardy. The court isn’t necessarily saying Beatrice was unduly influenced, but the timing is so suspicious it requires the beneficiary – Clara, in this case – to prove the document reflects Beatrice’s true, voluntary intent. It’s a heavy burden. We’ve seen cases drag on for years, eroding estate assets with legal fees, simply because of this timing issue. The presumption operates to protect vulnerable individuals from coercion during a period when they may be particularly susceptible.

The rule isn’t about who influenced Beatrice, but when. Even if Clara and Beatrice had a long-standing agreement about the necklace, the proximity of the codicil’s execution to Beatrice’s death will trigger scrutiny. Proving lack of undue influence requires demonstrating Beatrice was of sound mind, acted freely, and fully understood the implications of the change. This often involves procuring testimony from the drafting attorney (if any), witnesses to the signing, and even medical evaluations contemporaneous with the document’s execution. Without robust evidence, the court may invalidate the codicil, reverting to the terms of the prior Will, or to intestate succession if no prior Will exists.

For deaths occurring on or after April 1, 2025, the small estate threshold for personal property is $208,850 (per CPC § 13100). This allows heirs to skip full probate via affidavit. This rate is fixed and will not adjust again until April 1, 2028. However, even a small estate won’t escape this rule if a late-dated testamentary change is contested. The 120-day rule applies regardless of the estate’s overall value.

I’ve been practicing estate planning and tax law for over 35 years, and I’ve repeatedly seen the consequences of overlooking this seemingly technical rule. As a CPA, I’m uniquely positioned to advise clients not just on document preparation, but also on the tax implications of those decisions – crucial when dealing with assets that may receive a step-up in basis. Proper valuation, combined with proactive estate planning, can minimize challenges and maximize benefits for your heirs.

What happens if the Will is challenged due to undue influence?

A challenge to a Will based on undue influence claims the testator’s free will was overcome by another. This isn’t about simple persuasion; it requires proof of coercion, manipulation, or overbearing pressure that resulted in a testamentary document not reflecting the testator’s true wishes. Evidence might include isolation of the testator, control over their finances, threats, or a confidential relationship coupled with suspicious circumstances, like the 120-day rule triggering the presumption. The burden of proof typically falls on the contestant, though the burden can shift depending on the specific facts and relationship between the parties.

How does AB 2016 affect the timeline for transferring assets?

Under AB 2016, primary residences valued at $750,000 or less qualify for simplified transfer for deaths on or after April 1, 2025. In 2026, this remains active law, allowing qualifying homes to bypass formal probate via a simplified petition rather than a 12-month court process. While AB 2016 streamlines the process for eligible properties, it doesn’t override the 120-day rule. A late-dated change affecting the transfer of that residence would still be subject to challenge.

What is the timeframe for creditors to make claims against an estate?

Probate cannot be closed until the mandatory 4-month creditor claim period expires under Probate Code § 9100. This window begins the day ‘Letters’ are issued to the representative, serving as a mandatory cooling-off period even if the estate has no known debts. This period runs concurrently with the 120-day challenge window, so any challenges to the Will must be resolved before the estate can be finalized and distributed.

Are surety bonds always required in probate?

Unless explicitly waived in the Will or by all beneficiaries in writing, the court mandates a Surety Bond per Probate Code § 8482. This bond protects the estate’s value; the premium is calculated based on the total value of personal property plus annual income, often costing the estate thousands in non-refundable fees. A contested Will, particularly one challenged under the 120-day rule, increases the likelihood the court will require a bond to safeguard the assets during the litigation.

What impact will the OBBBA have on estate tax planning?

The 2026 ‘TCJA Sunset’ was officially averted by the One Big Beautiful Bill Act (OBBBA). As of January 1, 2026, the Federal Estate Tax Exemption is permanently set at $15 million per person ($30 million for married couples), effectively eliminating the federal ‘Death Tax’ for nearly all families. While the OBBBA mitigates federal estate tax concerns, it doesn’t diminish the importance of addressing the 120-day rule and ensuring testamentary documents are executed well in advance of any health crisis.

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

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.

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.
