Many married couples assume that if they create a revocable living trust, they will simply have “one trust.” In reality, the answer depends largely on where they live, how they own their property, and their estate planning goals. While some states make a joint trust practical and efficient, others are generally better suited for separate trusts—even though the law rarely requires one approach over the other.
Understanding the difference can help couples avoid unnecessary probate, simplify administration, minimize taxes, and ensure their wishes are carried out exactly as intended.
One of the most common questions we hear from clients is:
“Should we have one joint trust or two separate trusts?”
The answer is that very few states legally require one approach over the other. Instead, the decision depends on:
- Whether your state follows community property or common law property rules
- How assets are titled
- Whether estate tax planning is necessary
- Asset protection goals
- Blended family concerns
- Medicaid planning considerations
- Administrative simplicity
For many married couples, either option can work—but one may be significantly better depending on the circumstances.
First: Community Property States vs. Common Law States
The biggest distinction begins with how your state treats marital property.
Community Property States
Community property states generally recognize that assets acquired during marriage belong equally to both spouses.
These states are:
- Arizona
- California
- Idaho
- Louisiana
- Nevada
- New Mexico
- Texas
- Washington
- Wisconsin
Alaska also allows couples to elect community property treatment through a special agreement or trust.
Because community property is already considered jointly owned, these states frequently make joint revocable living trusts an attractive option.
Common Law States
The remaining states—including Pennsylvania, New Jersey, Florida, Maryland, Delaware, Tennessee, and most others—are common law property states.
In these states:
- Property belongs to whoever owns it.
- Married couples can jointly own assets.
- Each spouse may also own separate assets.
Because ownership can vary significantly, attorneys often recommend separate trusts, particularly when spouses have different assets or planning goals.
Is Any State Required to Use One Trust?
The short answer is no.
No state has a law stating that every married couple must have:
- one joint trust, or
- two separate trusts.
Instead, state law affects which structure makes the most sense.
Think of it like choosing between filing taxes jointly or separately. The law allows multiple options, but one may produce a better outcome.
When Joint Trusts Make Sense
A single joint revocable living trust often works well for couples who:
- are in long-term first marriages
- have identical beneficiaries
- own most assets together
- have similar estate planning goals
- are comfortable managing all assets together
Typical advantages include:
Simplicity
Only one trust document.
One trustee structure.
One amendment process.
One funding process.
This can significantly reduce administrative work.
Easier Asset Management
Instead of deciding which trust owns which asset, everything can usually be transferred into the same trust.
Examples include:
- residence
- joint investment accounts
- bank accounts
- vacation homes
Lower Legal Costs
One trust generally costs less to prepare than two separate trusts.
Administration after the first spouse dies may also be somewhat simpler.
Better for Community Property
In states like California or Texas, joint trusts often coordinate naturally with community property ownership.
Proper drafting may also preserve favorable tax treatment, including a full step-up in basis for community property assets.
When Separate Trusts Make More Sense
Many attorneys recommend separate trusts in common law states.
Separate trusts often provide greater flexibility when:
- spouses own different assets
- one spouse owns a business
- there are children from prior relationships
- asset protection is important
- estate tax planning is involved
Separate Property
Suppose:
Husband owns:
- rental properties
- investment portfolio
- business
Wife owns:
- inherited assets
- retirement accounts
- separate brokerage account
Maintaining separate trusts helps preserve ownership and simplifies administration.
Blended Families
Second marriages frequently benefit from separate trusts.
For example:
John has two children.
Mary has three children.
Each spouse may want:
- income for the survivor
- principal preserved for their own children
Separate trusts often make these intentions much easier to accomplish.
Creditor Protection Planning
While revocable trusts generally do not protect assets from the grantor’s creditors during life, separate trusts may better position assets for planning after the first spouse dies through continuing trusts for the surviving spouse.
Estate Tax Planning
Although the federal estate tax exemption is historically high, some states impose their own estate tax with much lower exemption amounts.
Separate trusts may preserve each spouse’s exemption through:
- bypass trusts
- credit shelter trusts
- family trusts
This can substantially reduce estate taxes in certain situations.
States Where Separate Trusts Are Common
Although not legally required, many estate planning attorneys frequently prepare separate trusts in states such as:
- Pennsylvania
- New Jersey
- Maryland
- Delaware
- Virginia
- North Carolina
- Florida
- Georgia
- Tennessee
This is largely because these are common law property states where spouses often maintain individually titled assets.
States Where Joint Trusts Are Especially Common
Joint trusts are particularly popular in:
- California
- Texas
- Arizona
- Washington
- Nevada
- Wisconsin
- Idaho
- New Mexico
Again, this is not because the law requires one trust.
Rather, community property rules often make one joint trust efficient.
What About Pennsylvania?
Pennsylvania residents frequently ask whether they should create one trust together.
The answer is:
Usually not—but it depends.
Pennsylvania is a common law state.
Many married couples own:
- separate retirement accounts
- inherited property
- individually titled investments
- businesses
- separate real estate
As a result, attorneys commonly recommend separate revocable trusts.
However, couples with modest estates and nearly all jointly owned property may still find a joint trust appropriate.
What About Florida?
Florida also does not require separate trusts.
Many Florida attorneys prepare:
- one joint trust for first marriages
- separate trusts for blended families or higher-net-worth couples
Florida homestead laws also create unique planning issues that should be addressed by an experienced estate planning attorney.
Texas Is Different
Texas is a community property state.
Joint trusts are extremely common because community property naturally lends itself to unified planning.
However, even in Texas, separate trusts may be appropriate if:
- one spouse owns significant separate property
- inheritances are involved
- there are children from previous marriages
- business succession planning is necessary
What Happens When One Spouse Dies?
This is one of the biggest differences between joint and separate trusts.
Joint Trust
Depending on how the trust is drafted:
- survivor often becomes sole trustee
- trust may continue unchanged
- trust may split into multiple subtrusts
- estate tax planning provisions may activate
Separate Trusts
Each spouse’s trust generally remains separate.
After the first death:
- deceased spouse’s trust becomes irrevocable
- survivor continues controlling his or her own trust
- inherited assets are administered according to the deceased spouse’s instructions
This often provides stronger protection for children and intended beneficiaries.
Does Having Two Trusts Mean Everything Is Separate?
Not at all.
Many couples using separate trusts still own property jointly.
Examples include:
- jointly owned home
- joint checking account
- jointly owned investment accounts
The trusts simply provide separate estate planning vehicles for each spouse.
What About Retirement Accounts?
Retirement accounts usually should not be retitled into a revocable living trust during the account owner’s lifetime.
Instead:
- IRAs
- 401(k)s
- 403(b)s
- pensions
remain individually owned.
The trust may instead be named as a beneficiary in appropriate circumstances after careful legal and tax advice.
Which Option Costs Less?
Generally:
Joint trust
- lower initial legal fees
- fewer documents
- simpler funding
Separate trusts
- higher upfront cost
- greater flexibility
- easier administration when ownership differs
- often better for complex estates
The additional cost is frequently modest compared to the long-term benefits of a plan tailored to your family’s needs.
Factors to Discuss With Your Estate Planning Attorney
Rather than focusing on whether your state “requires” one trust or two, ask questions such as:
- Do we own most property jointly or separately?
- Is this a first marriage or a blended family?
- Do we have children from previous relationships?
- Are estate taxes a concern?
- Do either of us own a business?
- Have either of us inherited significant assets?
- Are creditor protection or Medicaid planning goals important?
- Would one trust make administration simpler, or would separate trusts provide better flexibility?
These answers often matter far more than the state in which you live.
The Bottom Line
Contrary to what many people believe, no state generally requires every married couple to use one joint trust or two separate trusts. Instead, the best approach depends on the intersection of state property laws, the couple’s assets, family dynamics, and long-term planning objectives.
Community property states often lend themselves to joint revocable living trusts because marital assets are treated as jointly owned, making administration more streamlined. In common law states, however, separate trusts are frequently preferred when spouses own different assets, have children from prior relationships, own businesses, or want additional flexibility after the first spouse’s death.
The most effective estate plan is not the one that follows a one-size-fits-all rule—it is the one that reflects your family’s unique circumstances. An experienced estate planning attorney can evaluate your assets, ownership structure, tax considerations, and personal goals to recommend whether a joint trust or separate trusts will best protect your loved ones and preserve your legacy.
If you and your spouse are considering creating or updating your estate plan, speaking with an attorney before choosing a trust structure can save your family significant time, expense, and uncertainty in the future. A carefully designed trust is more than just a legal document—it is a roadmap that helps ensure your wishes are honored when your family needs it most.
