Can My Executor Decide Where I Was Domiciled

Barry lost everything. Not to creditors, not to a bad investment, but to a misplaced codicil. He’d painstakingly updated his estate plan, intending to move his domicile to Nevada for tax purposes. But the revised document, signed and witnessed, never made it into his safe deposit box. His executor, unaware of Barry’s intentions, filed probate in California, triggering a hefty estate tax bill he could have avoided. The cost? Nearly $800,000 in taxes that could have been saved with proper domicile planning.

As an Estate Planning Attorney and CPA with over 35 years of experience here in Escondido, I’ve seen this scenario play out far too many times. The critical issue isn’t just having an estate plan; it’s ensuring it’s executed flawlessly and that your domicile is established beyond reproach. Your executor doesn’t get to decide where you were domiciled; they must prove it based on solid evidence. And the burden of proof is significant.

What Exactly Is Domicile, and Why Does It Matter?

Domicile isn’t simply where you happen to live. It’s your true, fixed home—the place you intend to return to, even if you’re temporarily elsewhere. It’s the state whose laws govern your estate, and it has enormous tax implications. For California residents, this means potential estate taxes and adherence to California’s unique probate rules. Establishing domicile in a state like Nevada, Texas, or Florida can significantly reduce or even eliminate state estate taxes.

However, simply intending to move isn’t enough. The Franchise Tax Board (FTB) looks at a multitude of factors to determine your true domicile. It’s a detailed investigation, and your executor will have to present compelling evidence to overcome any presumption that you remained a California resident.

What Kind of Evidence Will the FTB Examine?

The FTB isn’t interested in a simple statement from your executor. They’ll conduct a thorough review of your life, looking for concrete evidence to support your claimed domicile. This is where the details matter. They’ll examine things like:

• Location of your primary residence: Where did you spend the majority of your time?
• Physical presence in the state: How many days per year were you actually residing in the claimed domicile state?
• Location of your bank accounts and investments: Where are your financial assets held?
• Location of your doctors, dentists, and other healthcare providers: Where did you receive medical care?
• Location of your club memberships and social connections: Where were you actively involved in community life?
• Location of your voter registration and driver’s license: These are key indicators of your intent.

It’s easy to see how a seemingly minor detail—like continuing to see a California-based specialist—can undermine your efforts to establish domicile elsewhere. This is where my CPA credentials prove invaluable. I can help you proactively structure your affairs to support your desired domicile, minimizing the risk of a costly audit.

How Does California Probate Law Impact Domicile?

If your estate is complex, or your real property exceeds certain thresholds, understanding California’s probate procedures is crucial. For deaths on or after April 1, 2025, a Petition for Succession under AB 2016 (Probate Code § 13151) will be available for a primary residence valued up to $750,000. However, remember that to qualify, your total non-real estate assets must typically remain below the separate $208,850 Small Estate limit. This is a significantly different process than attempting to use the Small Estate Affidavit which is strictly for real property valued under $69,625 like timeshares or vacant land. Your executor needs to be prepared to navigate this legal landscape effectively.

What if I Spend Less Than 183 Days in California?

Spending less than 183 days in California does not automatically terminate residency; the FTB uses the ‘Closest Connection’ test (evaluating 19 factors like your primary doctor and social ties) to determine domicile. Many clients assume that simply becoming a ‘snowbird’ shields them from California taxes, but that’s a dangerous misconception.

Protecting Your Estate: Proactive Planning is Essential

Don’t let Barry’s fate be yours. Proactive domicile planning is a critical part of a comprehensive estate plan. It’s not enough to simply sign a new will or trust. You need to actively align your life with your chosen domicile, and ensure your executor has access to all the necessary documentation to support your claim. We’ll meticulously document your intentions and create a clear audit trail, including gathering evidence that may be requested by the FTB, such as Form 4600 (Residency Questionnaire), which scrutinizes every aspect of your life. Remember, the One Big Beautiful Bill Act (OBBBA) permanently increased the Federal Estate Tax Exemption to $15 million per person effective Jan 1, 2026, but state estate tax laws remain a significant concern.

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.

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.

Controlling Legal Standards for Establishing Domicile and Residency

• Residency Guidelines: FTB Pub 1031 (Guidelines for Determining Resident Status)
  This is the primary resource for the “Closest Connection” test. In 2026, it details how the FTB evaluates 19 factors—including the location of your healthcare providers and social ties—to determine if your presence in the state is “permanent” or merely “transitory.”
• Voter Registration: California Secretary of State – Voter Registration
  Updating your voting address is a critical indicator of intent. For the June 2, 2026, Primary Election, the deadline to register online is May 18, 2026. This serves as a public declaration of your primary home.
• Federal Estate Tax: IRS Estate Tax Overview
  While domicile determines state tax, this resource outlines federal guidelines. It reflects the 2026 OBBBA update, which permanently set the federal estate tax exemption at $15 million per person ($30 million for couples), indexed for inflation.
• Proof of Residency: California DMV – REAL ID Checklist
  Since the federal enforcement deadline passed in 2025, a REAL ID is mandatory for domestic flights. This page lists the specific residency documents (e.g., utility bills, tax returns) that the state accepts as proof of a permanent California address.
