Making Your Estate Plan Legal in California

Dax just lost his mother, Evelyn. She had a meticulously handwritten codicil altering her trust, but it wasn’t witnessed or notarized according to California law. Now, his family faces a costly and protracted probate battle, easily exceeding $50,000 in legal fees, just to determine how Evelyn intended her assets to be distributed. A properly executed estate plan, even a simple one, could have saved them this heartache and expense.

What Happens If My Will Isn’t Properly Witnessed in California?

California has very specific requirements for the validity of wills and trusts. A holographic will (entirely handwritten) is permissible, but even then, it must demonstrate testamentary intent – meaning it clearly expresses the intent to transfer assets at death. However, most wills are typed or printed, and these require two adult witnesses who are present when the testator (the person making the will) signs the document, and who then sign the will themselves in the testator’s presence. A codicil, which amends an existing will, has the same strict witnessing requirements. Failure to adhere to these rules renders the will (or codicil) invalid, and the estate will be distributed according to California’s intestate succession laws – which may not align with the deceased’s wishes.

How Does Proposition 19 Affect Inheritance of Property in California?

Proposition 19 significantly altered the rules regarding property tax transfers. Under Proposition 19, heirs only keep a parent’s low property tax base if they move into the home as their primary residence within one year. Critically, for 2026, the tax-free ‘basis boost’ is capped at $1,044,586 over the original taxable value; any value exceeding this adjusted cap results in a partial reassessment even if the child moves in. This impacts high-value properties in particular, and proper estate planning can mitigate these potential tax liabilities through strategies like irrevocable trusts or carefully structured gifting.

What is the Small Estate Threshold in California and How Does it Work?

Many Californians are surprised to learn that not all estates require formal probate. For deaths occurring on or after April 1, 2025, assets exceeding $208,850 generally trigger full probate. However, per Probate Code § 13050, this calculation MUST exclude all California-registered vehicles (regardless of value), boats, and up to $20,875 in unpaid salary. Furthermore, AB 2016 now allows a simplified ‘Primary Residence’ petition for homes valued up to $750,000, significantly expanding probate shortcuts. Utilizing these provisions can save substantial time and expense for qualifying estates.

What Happens to Digital Assets After Death?

The digital world presents unique estate planning challenges. Per the Revised Uniform Fiduciary Access to Digital Assets Act (RUFADAA), custodians like Apple or Google are legally prohibited from granting executors access to the content of emails or private messages without ‘explicit written direction’ in the will or trust. Metadata (the ‘catalog’) may be accessible, but the private content remains locked without this specific legal trigger. A dedicated digital asset clause, clearly outlining access permissions and preferred handling, is crucial to avoid disputes and ensure these valuable assets are managed according to the deceased’s wishes.

What Role Does a CPA Play in Estate Planning?

As an attorney and a CPA with over 35 years of experience, I bring a unique perspective to estate planning. It’s not just about transferring wealth; it’s about transferring it efficiently. A CPA understands the implications of step-up in basis for inherited assets, minimizing capital gains taxes. We can also accurately value complex assets like business interests or real estate holdings, essential for accurate tax reporting. Ignoring the tax consequences can inadvertently diminish the inheritance your loved ones receive, and a proactive approach is always best.

What if I Become Incapacitated – How Does That Affect My Estate Plan?

A comprehensive estate plan includes more than just a will or trust. Advance Healthcare Directives, including a Durable Power of Attorney for Healthcare and a HIPAA Release, are essential to ensure your wishes are honored if you become unable to make medical decisions. Under both federal HIPAA and the California Confidentiality of Medical Information Act (CMIA), medical providers are strictly barred from sharing details with family unless a HIPAA Release is integrated into the Advance Healthcare Directive. Without this, a spouse may be forced to obtain an emergency court-ordered conservatorship just to speak with a surgeon.

What are the Requirements for Businesses in My Estate Plan?

If you own a business, your estate plan requires specific attention. Under the Corporate Transparency Act (CTA), all non-exempt small businesses must maintain active BOI Reports with FinCEN. Upon the death of a member, the estate or successor has exactly 30 days from the date the estate is settled to file an updated report; failure to meet this window triggers non-waivable fines of $500 per day. Failing to address business succession planning can lead to disruption, loss of value, and even legal liabilities.

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.

• Planning: Review future needs regularly.
• Validation: Check statutory rules.
• Parties: Update personal information.

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.

• Property Tax Reassessment (Prop 19):
  California State Board of Equalization (Prop 19)
