You signed a trust to make things easier for your children. But if one child wants to keep the house and another wants a share of its value, who gets to decide—and how will the others be treated fairly?

A trust is paperwork. Planning is what makes it work.

The purpose is to give the trustee appropriate authority to decide which child receives the house, together with a duty to balance the other children's shares through the remaining assets. That can reduce future friction and the risk of an avoidable sibling transfer. The restatement itself does not guarantee protection from reassessment.

Why the order of the transfers matters

Suppose two children first receive a one-half interest in the home. One then decides to keep it and acquires the other's half. The county assessor can generally reassess the acquired half as a sibling-to-sibling transfer, even though the child taking the house intends to live there. Occupancy does not turn that later sibling transfer into an inheritance directly from the parent.

Where the trust permits it, a successor trustee may instead allocate the home directly to one child and use other assets to satisfy the other child's share. Supporting documents and assessor review matter. Marin County Assessor: trusts and sibling transfers.

The Board of Equalization's current guidance recognizes a qualifying non-pro-rata distribution when the home's market value does not exceed the receiving child's share of the entire estate. The other Proposition 19 requirements still apply. BOE Letter 2026/026, Questions 41–42.

Authority to allocate, with a duty to equalize

After a death, the county assessor may request the trust to identify the beneficial ownership and review the transfer. Clear allocation powers and equalization instructions help document what the successor trustee is authorized and required to do. The actual beneficial interests and distribution still control the tax analysis. Marin County Assessor: review of trust documents.

A well-considered restatement can authorize the successor trustee to make that allocation and direct how the beneficiaries' shares should be balanced. Equal shares do not always require each child to receive the same fraction of every asset.

Consider an estate with a $1.2 million home and $1.2 million in other distributable assets, divided equally between two children. Allocating the home to one child and the other assets to the second may accomplish the intended balance. If the home represents nearly the entire estate, the same approach may not be feasible without a different funding arrangement.

The instructions should address who may receive the home, how the trustee makes that decision, the valuation process, available assets, expenses and any conflicts. The trustee must follow the actual trust terms and applicable duties. Review the proposed distribution before recording deeds or committing to a buyout.

Proposition 19 remains a separate eligibility question

For the family-home exclusion, the property must qualify as the parent's principal residence and become an eligible inheriting child's principal residence. At least one qualifying child must establish residence within one year; every beneficiary need not move in. The trust need not specifically name an occupant to meet a Proposition 19 title requirement. Continuing qualifying residence matters. BOE Letter 2026/026, occupancy guidance and Question 40.

The ordinary filing periods are one year for the homeowners' or disabled veterans' exemption and three years—or before a third-party transfer, if earlier—for the intergenerational exclusion claim. Special late-filing rules exist. Confirm the transfer date and deadlines promptly rather than assuming the clock begins when the trustee distributes the property. BOE Proposition 19 overview and filing checklist.

The exclusion also has a value limit

For transfers from February 16, 2025 through February 15, 2027, the cap equals the property's factored base year value plus $1,044,586. Value above the cap can increase the taxable assessment even when the other exclusion requirements are met. The applicable adjustment depends on the transfer date. BOE Letter 2025/009; BOE Letter 2026/026, New Taxable Value.

Review the instructions before your family needs them

Ask whether your trust gives the successor trustee suitable allocation authority and a clear equalization obligation. Then ask whether the assets and your children's likely intentions make those instructions workable.

An existing trust may already provide useful authority. A full restatement may be appropriate when substantial changes are needed. The recommendation should follow a review of the documents and facts.

If you are considering a new estate plan or full restatement, request an Estate-Planning Briefing. Complete the required Risk Exposure Mapping Form before the meeting.
