Can I Be Domiciled in Riverside If I Travel Often

Lillian just received a devastating phone call. Her mother, Rose, passed away unexpectedly while snowbirding in Arizona. Rose meticulously prepared a codicil to her trust, attempting to update beneficiary designations and address the Arizona property. Unfortunately, the codicil wasn’t properly witnessed, rendering it invalid. Now, Lillian faces probate, significant legal fees, and a prolonged process, all because of a technicality that could have been avoided with proactive estate planning. This situation highlights the critical importance of ensuring your estate plan is not only created but also legally sound and continuously reviewed, especially when residency becomes complex due to travel.

Determining domicile—your true, fixed home for legal purposes—is far more nuanced than simply having a mailing address. For many of my clients in Temecula and the surrounding Riverside County, frequent travel creates uncertainty about where they’ll be considered legally resident, impacting everything from estate taxes and income tax to probate proceedings and even jury duty. It’s not about the number of days you spend in California, but the totality of your connections.

The biggest misconception I encounter is that spending less than 183 days in California automatically terminates residency; the FTB uses the ‘Closest Connection’ test (evaluating 19 factors like your primary doctor and social ties) to determine domicile. Clients often believe a simple calendar count will suffice, but the Franchise Tax Board (FTB) delves much deeper. They’re looking for evidence of your intent—where you genuinely consider home.

Many assume that owning property establishes domicile, but that’s not necessarily true. Rose owning a home in Arizona didn’t automatically make her an Arizona resident for all purposes, nor did maintaining a home in Riverside guarantee California residency. It’s a combination of factors, and the FTB’s scrutiny can be intense.

As an Estate Planning Attorney and CPA with over 35 years of experience, I’ve seen firsthand how a poorly defined domicile can lead to unintended tax consequences and probate complications. My clients benefit from this dual perspective; I can navigate the legal and tax ramifications of their travel habits to ensure their estates are protected. Specifically, understanding the ‘step-up in basis’ for assets like real estate—a crucial capital gains benefit—requires a clear understanding of domicile at the time of death. Proper valuation is also heavily dependent on this determination.

Consider the scenario where you’re a snowbird. You spend six months in California and six months in Arizona. The FTB will look beyond the equal time split. They’ll examine where your driver’s license is issued, where you’re registered to vote, where your bank accounts are held, and where you receive your mail. Even seemingly minor details, like the location of your dentist or where you have your car serviced, can factor into their decision.

• Driver’s License and Vehicle Registration: Maintaining a valid California driver’s license and registering your vehicles in California are strong indicators of residency.
• Voting Registration: Being registered to vote in California and actively voting in elections demonstrates a connection to the state.
• Financial Accounts: The location of your primary bank accounts and investment accounts is a significant factor.
• Healthcare Providers: Your primary care physician and specialists should be located in California.
• Social Ties: Maintaining close relationships with family and friends in California strengthens your claim to residency.

Furthermore, the FTB will use Form 4600 (Residency Questionnaire) to scrutinize your life, including the location of your dentist, the registration of your pets, and where you keep your safe deposit boxes. This form requires meticulous documentation and a clear, consistent narrative of your connections to California.

What Happens if My Domicile is Unclear?

If your domicile is ambiguous, the FTB—or a probate court—will make a determination based on the evidence presented. This can lead to unintended consequences, including:

• Estate Tax Liabilities: If you’re considered a resident of a state with an estate tax (currently not California, but rules can change!), your estate may be subject to that state’s tax laws. The 2026 ‘Sunset’ was averted by the One Big Beautiful Bill Act (OBBBA), which permanently increased the Federal Estate Tax Exemption to $15 million per person effective Jan 1, 2026. However, understanding your domicile remains crucial for proper estate tax planning.
• Income Tax Issues: You could be subject to income tax in a state where you don’t intend to reside.
• Probate Jurisdiction: The probate process may be initiated in the wrong state, leading to delays and increased costs.

How Can I Establish and Maintain California Domicile While Traveling?

Proactive planning is essential. Here’s what I advise my clients:

• Maintain Strong California Ties: Continue to actively participate in California life—vote, bank, and receive healthcare here.
• Document Everything: Keep records of your travel, financial transactions, and any other evidence supporting your California connections.
• Review Your Estate Plan Regularly: Update your trust and other estate planning documents to reflect your current situation and intentions.
• Formalize Your Intent: Consider creating a declaration of domicile, a formal statement affirming your intention to remain a California resident.

It’s also crucial to understand the distinction between the Small Estate Affidavit (strictly for real property <$69,625, used for timeshares/vacant land) and AB 2016. For deaths on or after April 1, 2025, a primary residence valued up to $750,000 qualifies for a 'Petition for Succession' under AB 2016 (Probate Code § 13151). Remember this is a "Petition" that requires a Judge's Order, NOT an "Affidavit." To qualify, the decedent's other non-real estate assets (cash, stocks, etc.) must typically remain below the separate $208,850 Small Estate limit.

Establishing and maintaining a clear domicile is not simply a legal formality; it’s about protecting your assets, ensuring your wishes are honored, and avoiding unnecessary complications for your loved ones. If you frequently travel and are concerned about your domicile, I strongly recommend consulting with an experienced estate planning attorney and CPA to develop a plan tailored to your specific circumstances.

How do probate courts in California evaluate intent when a will is challenged?

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 create a valid document, you must ensure the signer has testamentary capacity, strictly follow will legal requirements, and ensure you are correctly identifying the will maker to prevent identity disputes.

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.

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 permanent federal estate tax exemption of $15 million per person ($30 million for couples), effective Jan 1, 2026.
• 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.
