Most married couples in Tennessee assume the surviving spouse automatically inherits everything. That assumption is wrong, and it can create serious financial hardship for the people you most want to protect.
Under T.C.A. § 31-2-104, if you die without a will and you have surviving children, the state divides your estate between your spouse and your children. Your spouse does not receive the full estate. They receive either a child’s share or one-third of the estate, whichever is greater. If your children are minors, this division can leave your surviving spouse without access to the full financial resources they need to keep the household running.
Choosing the best type of will for married couples is not about finding a convenient online template. It is about understanding how different legal structures interact with Tennessee law and your family’s specific circumstances.
The Four Main Will Types for Married Couples
Most couples encounter the same four options when researching wills. Each serves a different purpose, and the differences matter significantly in a Tennessee probate context.
Separate Wills Offer the Most Flexibility
The most common and widely recommended approach for married couples is two separate, individually drafted wills. Each spouse has their own legal document. Each document can mirror the other exactly in terms of beneficiary designations and asset distribution, or they can differ to reflect each spouse’s individual wishes regarding property they own separately, specific gifts, or named guardians.
When separate wills are drafted to reflect a shared estate plan, attorneys often call them mirror wills. The term describes the intent, not a formal legal category. Each document stands alone. Each spouse can update their will independently if circumstances change, such as after the birth of a child, the purchase of a home in Shelby County, or a significant change in family finances. Review your wills every few years or after major life milestones to keep them aligned with your current situation.
A properly executed will for a married couple in Tennessee must comply with T.C.A. § 32-1-104, which requires the testator’s signature and the signatures of at least two witnesses, all signed in each other’s presence. A self-proving will also requires a notary, which streamlines the probate process in Shelby County by eliminating the need to locate and question witnesses after the testator’s death.
Joint Wills Can Leave the Surviving Spouse Tied to Terms They Did Not Expect
A joint will is a single legal document signed by both spouses, covering both of their estates. It sounds efficient. In practice, it can create serious problems.
In Tennessee, signing a joint will does not, by itself, bind the surviving spouse. State law provides that executing a joint will or mutual wills does not create a presumption of a contract to make a will or to refrain from revoking it (T.C.A. § 32-3-107(b)). But a contract of that kind can be established in other ways, such as provisions in the will that state the material terms of the agreement, an express reference in the will to a contract, or a signed writing (T.C.A. § 32-3-107(a)). When a joint will includes that kind of agreement, the surviving spouse can be held to the original distribution plan.
That is where the trouble starts. The surviving spouse may remarry. They may face unexpected medical expenses. A child may predecease them. The family’s financial situation may shift completely. If the joint will reflects a binding agreement, none of that may matter, and the surviving spouse may not be free to change how the estate passes. If it is unclear whether an agreement exists, the family may end up asking a court to decide.
That uncertainty is one reason many estate planning attorneys prefer separate wills. If you have found a joint will template online, talk with a Tennessee estate planning attorney before you use it.
Testamentary Trust Wills Protect Children and Blended Families
A testamentary trust will is a standard individual will that also creates a trust, activated at the testator’s death. This structure is particularly valuable for couples with minor children, significant assets, or blended family situations involving children from a prior relationship.
A will can direct property to a trustee to be administered according to the trust’s terms. This means you can leave assets to your surviving spouse for their lifetime benefit while ensuring that the remaining assets pass to your children from a first marriage after the surviving spouse’s death, rather than to a new spouse or their family. Without this structure, assets left outright to a surviving spouse can be redirected entirely away from children of a prior relationship, whether through remarriage, new estate planning, or simply changed intentions.
A testamentary trust also allows parents of minor children to specify the age at which a child receives a direct inheritance, who manages the funds in the meantime, and what the funds can be used for, covering education, healthcare, housing, and other needs. This level of control is not possible with a simple outright bequest in a basic will.
A word on probate: a testamentary trust does not avoid probate. The will must still pass through the Tennessee probate process before the trust activates. Couples interested in bypassing probate entirely would need a separate revocable living trust structure, which is a different planning tool and outside the scope of this comparison.
Simple Individual Wills for Couples With Straightforward Estates
For couples with modest assets, no children from prior relationships, and no complex business interests, a simple individual will may be entirely sufficient. Each spouse drafts their own document naming the other as the primary beneficiary and naming a contingent beneficiary in case both spouses die simultaneously or close in time.
Even here, the will for a married couple needs to be executed correctly under Tennessee law, not filled out through an online form that applies another state’s legal standards. Tennessee has specific requirements for valid execution, and a will that fails to meet them can be challenged or rejected during probate.
Pairing your will with a durable financial power of attorney and an advance healthcare directive ensures that your spouse has legal authority to act on your behalf if you become incapacitated before death, closing a gap that wills alone cannot address.
How to Choose the Right Structure for Your Marriage
The right answer for your family depends on three variables.
Children Determine How Much Protection You Need
Couples without children and without significant separately owned assets can often accomplish their goals with simple mirror wills. Couples with minor children need to think carefully about guardianship designations and whether a testamentary trust is the appropriate tool to manage inherited assets until children reach adulthood. A last will for a married couple with children from a prior relationship almost always warrants trust planning to prevent unintended disinheritance.
Blended Families Require Explicit Legal Structures
When one or both spouses have children from a previous relationship, a simple outright bequest to the surviving spouse may not protect those children. Tennessee law does not automatically preserve a child’s inheritance if the surviving spouse later remarries or updates their own estate plan. Explicit trust structures inside the will are the mechanism that holds those intentions in place.
Asset Complexity Affects How Much Coordination Your Wills Need
Couples with real property in multiple counties, business ownership interests, retirement accounts with named beneficiaries, and significant personal property benefit from wills that are coordinated with a broader estate plan. Not every asset passes through a will. Assets with named beneficiaries, such as IRAs and life insurance policies, pass outside the probate estate entirely. Your attorney can help you identify which assets are will-governed and which need separate beneficiary review.
Working With a Tennessee Estate Planning Attorney
The best type of will for married couples is the one that reflects your actual family structure, your Tennessee assets, and your intentions for protecting your husband or wife and making sure your kids are taken care of. That is not something a national template site can determine.
An experienced Tennessee estate planning attorney who knows Shelby County probate court can review your specific situation, explain which structure aligns with your goals, and draft documents that hold up when it matters most.
