In almost every situation, joint tenancy does override a trust. When property is held in joint tenancy with right of survivorship, the deceased owner’s share transfers to the surviving owner automatically at the moment of death, before a trust, a will, or any other estate planning document has a chance to act. If your plan assumes your trust controls a jointly held asset, it almost certainly does not.
Why Survivorship Beats the Trust
Joint tenancy is co-ownership in which each owner holds an equal, undivided interest in the whole property.1Legal Information Institute. Joint Tenancy The feature that matters here is the right of survivorship: when one owner dies, the surviving owners absorb the deceased owner’s share by operation of law. No court filing, no probate, no waiting.
A revocable living trust works differently. It only controls assets that have been formally retitled into the trust’s name, a step called funding the trust. If you sign a trust that gives your house to your daughter, but the deed still lists you and your brother as joint tenants, the trust’s instructions are irrelevant. Your brother inherits by survivorship, and the trust never touches the property. Title on the asset, not language in the trust document, decides what happens.
This is where most estate plans quietly fail. People draft a trust, list the property in it, and never change the deed. They assume mentioning the property is the same as transferring it. It isn’t. A trust is only as strong as its funding, and jointly held assets sit outside its reach.
Why a Pour-Over Will Doesn’t Fix This
Many estate plans include a pour-over will as a backstop. The idea is that anything you forgot to move into your trust during life gets poured over into the trust at death. That works for assets titled in your individual name that would otherwise pass through probate.
It does not work for joint tenancy property. Because the surviving owner takes the deceased owner’s share automatically, the property never enters the probate estate. A pour-over will only operates on assets that pass through probate. Jointly held assets skip probate by design, and the pour-over will has nothing to catch. If you were counting on it to redirect a jointly held house into your trust, that safety net isn’t there.
How to Actually Put Jointly Held Property Into a Trust
If you want your trust to control property currently held in joint tenancy, you have to change how the property is titled. The straightforward approach is for all joint tenants to sign a new deed transferring the property out of their individual names and into the trust’s name. If you and your spouse own a home as joint tenants, you would sign a deed conveying it to yourselves as trustees of your revocable living trust. Once the deed is recorded, the trust owns the property and its terms govern what happens at death.
Recording the new deed with the county recorder’s office is required. Government recording fees vary by jurisdiction and typically run between $25 and $125. Some jurisdictions also require supplemental forms describing the nature of the transfer. Moving property into your own revocable trust is generally not treated as a taxable sale or a change in beneficial ownership, so it usually will not trigger transfer taxes or, in most states, a property tax reassessment. Check your state’s rules before filing, because a few jurisdictions handle this differently.
Don’t Do It Alone
If only one joint tenant transfers their interest into a trust, the consequences can be significant and unintended. Courts in several states have held that when one joint tenant conveys their share into a trust, the conveyance destroys the unity of title and severs the joint tenancy. An Iowa appellate court, for example, ruled that one co-owner’s transfer of her interest in lakefront property into her trust converted the joint tenancy into a tenancy in common. The survivorship right was gone.
Severance means neither owner’s share automatically passes to the other anymore. Each share becomes a separate, inheritable interest that passes through the individual owner’s estate. If the whole point of the joint tenancy was to guarantee the surviving owner gets the property, a unilateral transfer into a trust can defeat that goal. Both joint tenants should be involved in any retitling decision, and ideally both should transfer their interests at the same time into the same trust or into coordinated trusts.
The Tax Cost of Leaving It in Joint Tenancy
Control is not the only issue. Joint tenancy can cost surviving owners real money in capital gains tax compared to holding the property in a trust. The issue is the step-up in basis, which determines how much taxable gain exists when the surviving owner eventually sells.
When someone dies, the tax basis of property included in their estate resets to the property’s fair market value at the date of death.2Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent For joint tenancy property, only the deceased owner’s share is included in the estate, so only that half gets the step-up. The survivor’s half keeps its original basis. Say a couple bought a house for $200,000 and it is now worth $800,000. One spouse dies. The survivor’s basis becomes roughly $500,000: their original $100,000 plus the deceased spouse’s stepped-up $400,000. Selling at $800,000 produces a $300,000 taxable gain.
Community Property Changes the Math
Married couples in community property states have a better option. Under federal tax law, when one spouse dies, both halves of community property receive a step-up in basis, not just the decedent’s half.3Office of the Law Revision Counsel. 26 USC 1014 – Basis of Property Acquired From a Decedent – Section: (b)(6) In the same example, the survivor’s basis would reset to the full $800,000, and a sale at that price would produce zero taxable gain.
Community property with right of survivorship gives married couples the automatic transfer that joint tenancy offers while preserving the full double step-up. Nine states follow community property rules: Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin. Alaska allows married couples to opt in. Holding community property in a revocable trust preserves the double step-up while also keeping the property under the trust’s control. If you live in a community property state and your home is titled in joint tenancy, it is worth asking an estate planning attorney whether retitling makes sense.
When Joint Tenancy Is Still the Right Choice
Joint tenancy is not inherently a bad tool. For married couples with modest assets, a jointly held home that passes by survivorship to the surviving spouse is simple, avoids probate, and costs nothing to set up. It works well when the surviving owner is exactly who you want to receive the property and there are no concerns about large capital gains.
The problems appear when joint tenancy conflicts with a broader estate plan, when the surviving owner is not your intended beneficiary, or when the partial step-up leaves the survivor with a big taxable gain. If you have a trust-based estate plan, every asset you hold in joint tenancy is effectively opting that asset out of your trust’s instructions. The fix is not complicated. Retitle the property into the trust, do it deliberately, involve all joint tenants, and record the new deed. The trust document alone will not do the job.
