Does Moving to San Diego Change Where I Probate

Emily recently called, frantic. Her mother passed away with a seemingly simple will, but Emily had moved to San Diego just six months prior. Her mother remained in Sacramento. Now, Emily’s aunt is challenging the will, claiming Sacramento is the proper venue for probate. Emily is facing potentially tens of thousands in legal fees just battling where the case should be heard – a heartbreaking situation easily avoided with proper planning.

As an Estate Planning Attorney and CPA with over 35 years of experience, I’ve seen this scenario play out far too often. Clients assume a change of address is straightforward, but it significantly impacts complex legal processes like probate. The question isn’t just can you move, but how does that move affect your estate plan, particularly regarding the location of probate proceedings?

What Determines the Proper Venue for Probate?

Probate jurisdiction isn’t automatically tied to your current residence. It’s based on domicile – a legal term meaning your primary, fixed home where you intend to return, even if temporarily absent. Simply 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. Establishing a new domicile requires more than just a mailing address; it necessitates a demonstrable shift in your life’s center.

How Does a Move Impact an Existing Will?

A will remains valid even after a move, provided it doesn’t create conflicts with the laws of your new domicile. However, a change in domicile can impact where the will is probated. Generally, probate occurs in the county where the decedent was domiciled at the time of death. If Emily’s mother remained a California resident with a fixed Sacramento address and intent to return, Sacramento remains the proper venue, despite Emily’s move. This doesn’t mean Emily is excluded from the process, but it does dictate the logistical and potentially legal hurdles she faces.

What if I Update My Will After Moving?

Updating your will after a move is crucial. While not strictly required, explicitly stating your new domicile within the document can solidify your intent. More importantly, consider a “portable will” – a will drafted to be recognized across state lines, should you relocate again. However, simply having a will isn’t enough; you must also ensure your beneficiary designations on accounts like 401(k)s and IRAs align with your estate plan and domicile.

What About Real Estate and the New AB 2016 Law?

California law surrounding smaller estates has changed dramatically. 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). This is a significant development, offering a simplified process compared to traditional probate. However, you must remember that this is a Petition that requires a Judge’s Order, NOT an “Affidavit.” It’s critical to distinguish this from the Small Estate Affidavit (strictly for real property <$69,625, used for timeshares/vacant land). Furthermore, to qualify, the decedent's other non-real estate assets (cash, stocks, etc.) must typically remain below the separate $208,850 Small Estate limit.

The CPA Advantage: Step-Up in Basis & Capital Gains

As a CPA as well as an attorney, I see many clients overlooking the tax implications of a move. A change in domicile can impact the step-up in basis of assets, potentially reducing capital gains taxes for your heirs. Properly documenting your domicile is vital should the IRS or FTB scrutinize your estate. Auditors 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. We proactively address these issues during estate planning, minimizing potential tax liabilities and ensuring compliance.

What About Business Assets and Income Sourcing?

If you own a business, moving doesn’t automatically shift the income source. Under updated Regulation Section 25136-2 (effective Jan 1, 2026), California sources asset management fees based on the domicile of the underlying investors, not the fund itself. This is a complex area, and proper structuring is essential to avoid unwanted California taxation.

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

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.
