Can a will control jointly owned assets

I recently had a client, David, come to me in a complete panic. His father had passed away with a seemingly valid will, but a significant portion of his estate – a beachfront property held jointly with his sister – was completely outside of it. David had assumed the will would dictate what happened to the entire estate, and he was devastated to learn that wasn’t the case. He’d spent months preparing for a smooth transition, and now faced a complicated and potentially costly legal battle with his sister over the property. It’s a surprisingly common misunderstanding, and often leads to unintended consequences and family conflict.

What Happens to Assets Held in Joint Tenancy?

The core principle is this: a will does not control assets that pass by operation of law. Jointly owned assets, particularly those held in joint tenancy with right of survivorship, bypass the probate process entirely and transfer directly to the surviving owner(s). This means that regardless of what your will says about that property, the surviving joint tenant automatically becomes the sole owner. It’s a powerful feature of joint ownership, but it requires careful planning. David’s father believed his will addressed the beachfront property, but because it was held jointly, the will simply had no legal effect over it.

How Does This Differ From Tenancy in Common?

It’s crucial to distinguish between joint tenancy with right of survivorship and tenancy in common. With tenancy in common, each owner holds a distinct share of the property, and their share is governed by their will. Upon death, that share passes to their designated beneficiaries. However, even in tenancy in common, the will only controls the deceased’s interest – the surviving co-owners retain their respective shares. The confusion arises because both scenarios involve multiple owners, but the legal consequences are dramatically different.

What About Community Property?

In California, community property – assets acquired during marriage – presents another layer of complexity. While a will can direct the disposition of a spouse’s half of the community property, the surviving spouse automatically owns their half regardless of the will’s instructions. Furthermore, if a property was acquired before the marriage, or as a gift or inheritance during the marriage, it is considered separate property. Separate property is also controlled by the will, unless it is held in joint tenancy.

The CPA Advantage: Understanding Step-Up in Basis

As both an Estate Planning Attorney and a Certified Public Accountant (CPA) with over 35 years of experience, I see firsthand how critical it is to consider the tax implications of asset ownership. One significant benefit of inheriting assets, whether through a will or directly, is the potential for a step-up in basis. This means the inherited asset’s tax basis is adjusted to its fair market value at the time of the owner’s death. This can dramatically reduce capital gains taxes when the asset is later sold. Properly structuring ownership – whether joint tenancy, tenancy in common, or as part of a Trust – impacts not only who receives the asset, but also how much tax is ultimately paid. Understanding this valuation aspect is where my CPA background provides immense value to my clients.

What About Bank Accounts and Digital Assets?

The same principles apply to bank accounts, brokerage accounts, and increasingly, digital assets. Accounts with “pay on death” or “transfer on death” designations – often referred to as TOD accounts – pass directly to the named beneficiary, bypassing probate and the will. Similarly, without specific RUFADAA language (Probate Code § 870) in your Trust or Will, service providers like Coinbase and Google can legally deny your executor access to your digital assets. Jointly held accounts function similarly to real estate held in joint tenancy; the surviving account holder gains immediate access.

What If The Estate Is Large Enough to Trigger Federal Estate Tax?

For larger estates, even assets passing outside of probate are counted towards the federal estate tax. However, the OBBBA permanently increased the Federal Estate Tax Exemption to $15 million per person effective Jan 1, 2026. While this provides a high threshold, careful planning is still essential. If combined ‘probate assets’ (excluding the AB 2016 residence) exceed $208,850 (the threshold effective April 1, 2025), they are subject to formal probate; a Will alone does not allow you to bypass this limit.

Protecting Your Assets With a Comprehensive Estate Plan

The key takeaway is that a will is not a one-size-fits-all solution. It’s essential to understand how different ownership structures impact your estate plan. For real property, distinguish between the Small Estate Affidavit (strictly for real property <$69,625, used for timeshares/vacant land) and AB 2016. 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). Remember this is a "Petition" requiring a Judge’s Order, NOT an "Affidavit." A comprehensive estate plan should consider all types of assets, and proactively address issues like joint ownership, community property, and digital assets. We work closely with clients to determine the most appropriate ownership structures, ensuring their wishes are not only reflected in their will but legally enforceable.

What standards do California judges use to determine a will’s true meaning?

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.

• Preparation: Review estate planning regularly.
• Validation: Check statutory rules.
• People: Update testator details.

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.

Resources for Asset Management & Transfer

• Property Tax Reassessment: California State Board of Equalization (Prop 19)
  This page details the “Base Year Value Transfer” rules. It explains that heirs can only avoid a property tax reassessment if the inherited home becomes their primary residence and the Homeowners’ Exemption is filed within one year of the date of death.
• Real Estate Probate (AB 2016): California Probate Code § 13151 (Petition for Succession)
  The specific statute for the AB 2016 process. It outlines the requirements for using a court-approved “Petition” (not an affidavit) to transfer a primary residence worth $750,000 or less (gross value) for deaths occurring after April 1, 2025.
• Small Estate Affidavit: California Probate Code § 13100 (Personal Property)
  Access the statutory language for the “Small Estate Affidavit.” This procedure is strictly for Personal Property (cash, stocks, vehicles) and is limited to estates with a total value of $208,850 or less (effective April 1, 2025).
• Federal Estate Tax Exemption: IRS Estate Tax Guidelines
  The authoritative federal resource for estate valuation. It reflects the 2026 exemption increase to $15 million per person, which is critical for high-net-worth asset planning and determining if an IRS Form 706 is required.
• Unclaimed Assets: California State Controller – Unclaimed Property
  The primary portal for executors and heirs to search for “lost” assets—such as forgotten bank accounts, uncashed dividends, and insurance benefits—that have been remitted to the State of California for safekeeping.
• Business/LLC Compliance: FinCEN – Beneficial Ownership Information (BOI)
  The official portal for corporate transparency reporting. Most domestic and foreign entities (LLCs, Corps) must file a report. Executors must verify compliance, as failure to update control information within 30 days of death can result in federal civil penalties.
