The four documents to have in place

1. Durable Power of Attorney (Prob. Code §§4000-4545)

California adopted the Uniform Statutory Form Power of Attorney. CA POAs must be signed by the principal and either notarized or witnessed by two adults.1A bank-friendly POA from a CA attorney runs $300–$1,000 and is meaningfully more readily accepted by financial institutions than generic out-of-state or online forms.

2. Advance Health Care Directive (Prob. Code §§4600-4806)

California uses a single document for medical advance planning — the AHCD. Unlike NY (which separates Health Care Proxy from Living Will), CA combines POA for healthcare and living-will provisions in one statutory form (Prob. Code §4701).2

3. POLST (Prob. Code §4780 et seq.)

For patients with serious illness, the Physician Orders for Life-Sustaining Treatmentform — signed by a physician, NP, or PA — carries portable medical orders that EMS and hospital staff will honor. Different from AHCD; both are valuable for advanced-illness patients.

4. Revocable Living Trust

The workhorse of California estate planning. CA’s statutory probate fee schedule plus the 12–18 month typical probate timeline make trust-based planning the default for almost any CA family with non-trivial assets. A typical CA revocable trust package runs $1,500–$4,500.

Prop 19 — the inheritance ambush

Effective February 16, 2021, Proposition 19 substantially narrowed the parent-child property-tax exclusion that had existed under prior law (Prop 58 / Prop 193). Before Prop 19, a child could inherit a parent’s home and keep the parent’s base-year property tax value — often producing decades of below-market property tax.3

Under Prop 19, the exclusion is now limited:

Inherited rental property or vacation homes are fully reassessed to market value at transfer. No parent-child exclusion applies. For a long-held Bay Area rental property with a $200k base-year value and $2M market value, the reassessment can produce property tax that exceeds rental income.

California's probate — and why families avoid it

California probate is expensive and slow. Two factors compound:

Small-estate alternatives are available:

For estates exceeding these thresholds without a trust, full probate is required — which is why nearly every CA family with meaningful assets sets up a revocable living trust instead.

California elder abuse and undue influence statutes

California has the most developed elder-abuse civil framework in the country — the Elder Abuse and Dependent Adult Civil Protection Act (EADACPA, W&I Code §15600 et seq.). Key features:5

If you suspect your parent is being financially exploited, CA elder-abuse statutes give you real legal levers. Many CA elder-law attorneys handle these on contingency given the statutory fee-shifting.
