California Estate Law · Prop 19
California Prop 19 Planning — Inherited Property and Trust Review.
Proposition 19, effective February 2021, fundamentally changed how California families plan for real property transfers. Trusts drafted before 2021 may no longer achieve what they were designed to do.
For families who own California real estate — especially multigenerational San Gabriel Valley and San Marino households — understanding and planning for Prop 19 is now a critical part of any estate plan review.
What Changed in 2021
The old rules no longer apply to most inherited property.
Before Prop 19
- Children could inherit a primary residence without reassessment — no limit on value
- Up to $1 million of other property (e.g., rentals, vacation homes) could be transferred without reassessment
- Children were not required to use the inherited property as their primary residence
- Existing trusts were widely used to preserve low property tax bases across generations
After Prop 19 (Feb 2021)
- $1 million exclusion for non-primary-residence property is eliminated entirely
- Primary residence exclusion requires the child to actually move in within one year
- Exclusion is capped — if the assessed value plus $1M is less than market value, partial reassessment occurs
- Trusts drafted before 2021 may not be optimized for the new rules — a review is essential
Who This Affects
Prop 19 affects nearly every California family with real property.
The impact is particularly significant for multigenerational families, homeowners in high-appreciation markets, and families whose estate plans were drafted before the 2021 effective date.
Families with rental or investment property
The $1M exclusion for non-primary-residence property is gone. Rental properties, vacation homes, and investment real estate are now fully subject to reassessment when transferred to children.
Trusts drafted before February 2021
Many existing revocable trusts were designed around the old exclusion rules. Without a review, they may inadvertently trigger reassessment — or miss planning opportunities the new law allows.
Blended families with stepchildren
Prop 19's exclusion only applies to biological or adopted children — not stepchildren. Blended families need specific planning to address this gap.
Families with a surviving spouse
Spousal transfers are not subject to reassessment, but transfers from a surviving spouse to children are. Trust structures that pass property through a surviving spouse can have unintended Prop 19 consequences.
Children who want to keep the family home
To claim the exclusion, a child must establish the inherited property as their primary residence within one year. Missing this window can result in full reassessment going forward.
High-appreciation San Gabriel Valley properties
Properties in San Marino, Arcadia, Pasadena, and the broader SGV have appreciated dramatically. The tax impact of reassessment on these properties is substantial — making planning especially valuable.
What a Trust Review Covers
A Prop 19 review is more than reading the document.
A genuine trust review for Prop 19 purposes requires understanding both the legal document and the family's actual circumstances — who the beneficiaries are, which properties are held, what their assessed versus market values are, and how the children intend to use inherited property.
In many cases, trust language can be updated to take advantage of legitimate Prop 19 planning strategies. In others, the most important step is simply ensuring the family understands what the current rules mean for them — and making any needed updates before a transfer occurs.
Review of current trust provisions
Analyzing how property is held, how it passes, and whether the existing language aligns with post-Prop 19 rules.
Property tax exposure assessment
Identifying which properties may be subject to reassessment, and the estimated financial impact.
Beneficiary and usage analysis
Understanding which children, if any, are likely to claim the primary residence exclusion — and what steps are needed.
Updated distribution and trust language
Revising trust terms where beneficial — to provide clarity, preserve optionality, and reduce unintended tax triggers.
Coordination with financial advisors
For properties with significant tax implications, we coordinate with CPAs and financial planners as needed.
"A trust drafted five years ago isn't a plan for today. California's property rules changed fundamentally in 2021 — and families who haven't reviewed their documents since then may be holding significant, invisible risk."
