Most married couples assume they need two separate trusts — one for each spouse. In reality, a joint revocable trust (also called a joint living trust or couples trust) is a single, unified document that covers both spouses, typically at half the cost and complexity of two separate trusts.
But joint trusts aren't the right choice for every couple. The structure that works best depends on your state's property laws, your estate size, whether you have children from prior relationships, and your liability exposure.
This guide explains everything: how joint trusts work, how they compare to separate trusts, what happens when the first spouse dies, the AB trust structure for estate tax planning, community property considerations, and how to set one up for $300–$1,500 online.
A joint revocable trust is a single trust created by two spouses together, with both serving as co-trustees. It's simpler and cheaper than two separate trusts for most couples. Upon the first death, it typically splits into a Survivor's Trust and a Decedent's Trust to preserve estate tax exemptions. Online platforms like Trust & Will offer couples trust plans starting at $349.
A joint revocable trust is a legal document that both spouses create and sign together. The key characteristics:
Like all revocable living trusts, a joint trust does not protect assets from creditors during the grantors' lifetimes — it's a management and probate-avoidance tool, not an asset protection tool.
The debate between joint and separate trusts is one of the most common questions in couples' estate planning. Here's how they compare:
| Factor | Joint Revocable Trust | Two Separate Trusts |
|---|---|---|
| Cost | Lower (one trust) | Higher (two trusts) |
| Simplicity | Simpler — one document | More complex — two documents, two sets of accounts |
| Blended families | Risky — harder to segregate each spouse's separate assets for different children | Better — each spouse controls their own separate share for their own children |
| Community property states | Works very well — jointly owned property fits naturally | More complicated asset division |
| Common law states | Works well if assets are jointly titled | Better for separately titled assets |
| Asset protection | Weaker — creditors of either spouse can reach all assets | Stronger — one spouse's creditors can only reach that spouse's trust |
| Estate tax planning | Requires AB/ABC trust structure at first death | Each trust can use each spouse's exemption independently |
| Best for | First marriages, shared assets, estates under $10M | Blended families, high liability, unequal assets, estates over $10M |
Bottom line: For most first-marriage couples with combined assets under $13.99 million and no significant liability concerns, a joint revocable trust is simpler, cheaper, and equally effective as two separate trusts.
Where you live has a major impact on how a joint trust works — specifically because of how state law treats property acquired during marriage.
In Arizona, California, Idaho, Louisiana, Nevada, New Mexico, Texas, Washington, and Wisconsin, most assets acquired during marriage are automatically owned 50/50 by both spouses ("community property"). Alaska also allows couples to opt into community property.
Community property has a critical tax advantage: when one spouse dies, the entire community property asset (not just the deceased's half) receives a stepped-up cost basis. This can eliminate capital gains tax on appreciated assets like stocks or real estate.
For couples in community property states, joint trusts work especially well because:
In common law states, property belongs to whoever paid for it or whose name is on the title. Married couples can own property jointly (joint tenancy or tenancy by the entirety) or separately.
In common law states, separate trusts sometimes make more sense if spouses have significant separately owned property — because clearly delineating each spouse's assets is easier with two separate trusts. However, for couples who hold most assets jointly, a joint trust works just as well.
Important: Transferring assets into a joint trust in a community property state can sometimes change the character of those assets. Always consult an estate planning attorney if you're converting community property into trust form in California, Texas, or other community property states — the steps matter for preserving the full stepped-up basis.
This is the most important part of understanding joint trusts. When the first spouse dies, a well-drafted joint trust doesn't just sit there unchanged — it typically splits into sub-trusts.
The most common structure is the AB Trust (also called a bypass trust or credit shelter trust). Here's how it works:
Trust A holds the surviving spouse's share of the assets (typically their 50% of community or marital property, plus any separate property). Key features:
Trust B holds the deceased spouse's share of assets, up to the federal estate tax exemption amount ($13.99 million per person in 2026). Key features:
In 2026, the federal estate tax exemption is $13.99 million per person ($27.98 million per married couple with portability). Without an AB trust, if the first spouse leaves everything outright to the survivor, the survivor only gets one exemption. With an AB trust, Trust B "locks in" the first spouse's exemption — effectively doubling the couple's total estate tax shelter.
For estates under ~$14 million, the AB trust structure is less critical because portability rules allow spouses to share exemptions — but it requires filing an estate tax return at the first death to elect portability. An AB trust automates this protection without requiring any action.
For very large estates, some couples use an ABC Trust structure (also called a QTIP trust structure). This adds a third sub-trust:
Same as above — the surviving spouse's revocable share.
Same as above — the deceased's exemption amount, sheltered from estate tax.
Trust C holds any assets above the deceased spouse's exemption amount. These assets qualify for the unlimited marital deduction, so they're not taxed at the first death. However, the surviving spouse only receives income from Trust C — they cannot access the principal freely, and the assets will be included in the surviving spouse's estate when they die.
This allows the first spouse to die while controlling where the assets ultimately go (e.g., to children from a first marriage) while still qualifying for the marital deduction and not triggering estate tax at the first death.
Who needs an ABC trust? Couples with estates exceeding the federal exemption ($13.99M per spouse), or couples where one spouse wants to ensure assets pass to children from a prior marriage rather than to the survivor's future spouse. For most couples, a simple AB trust or even a basic joint trust without sub-trusts is sufficient.
A joint revocable trust is the centerpiece, but a complete couples estate plan includes:
A pour-over will is a short will that "catches" any assets you forgot to put in the trust. It directs those assets to be transferred into the trust at death (via probate). Every trust should have a pour-over will for each spouse as a backup — Trust & Will and LegalZoom both include these automatically.
Authorizes your spouse (or another person) to manage financial matters — pay bills, manage investments, file taxes — if you become incapacitated. Important because the joint trust only covers trust assets; POA covers everything else (bank accounts not yet in the trust, tax filings, etc.).
Documents your wishes for medical care if you can't speak for yourself. Each spouse needs their own. Trust & Will's couples plan includes both.
Allows your spouse and/or children to access your medical information — necessary for coordinating care even if they're not making medical decisions.
Assets with named beneficiaries (IRAs, 401(k)s, life insurance, payable-on-death accounts) pass outside the trust entirely — make sure beneficiary designations are updated to coordinate with your trust plan.
Trust & Will's couples plan includes a joint revocable trust, two pour-over wills, two POAs, and two healthcare directives — everything you need, guided step-by-step. Starting at $349.

While both are living, both spouses are typically co-trustees and co-beneficiaries. You'll also name:
Online platforms like Trust & Will and LegalZoom guide you through a questionnaire and generate a state-specific trust document. An attorney can draft a more customized document if your situation is complex.
A revocable living trust must be signed by both spouses in front of a notary public (in most states). Some states also require witnesses. Trust & Will includes notarization guidance; you can use an online notary service like Notarize.com for convenience.
This is the most important step most people skip. An unfunded trust avoids nothing — assets must be re-titled into the trust's name before they can pass outside probate. This means:
| Option | Cost Range | What's Included | Best For |
|---|---|---|---|
| Trust & Will | $349 (Trust Plan) | Joint trust, 2 pour-over wills, 2 POAs, 2 healthcare directives | Most couples, straightforward assets |
| LegalZoom | $279–$599 | Living trust package; optional attorney review add-on | Couples wanting name-brand service |
| Local estate planning attorney | $1,500–$5,000 | Full customized package: trust, wills, POAs, healthcare directives, deed transfers | Blended families, business owners, estates over $5M |
| Big-city estate planning attorney | $3,000–$8,000+ | Same as above, more complex structures | High-net-worth couples, complex tax planning |
For the vast majority of couples — first marriages, combined assets under $5 million, no business interests, no children from prior relationships — an online service like Trust & Will provides a legally valid, comprehensive couples trust plan at a fraction of the attorney cost.
Online services work well for most couples, but consider an estate planning attorney if:
