What Is a Joint Will? And Why Most Michigan Couples Should Think Twice

What Is a Joint Will?

A joint will combines the testamentary wishes of two people into a single document. A married couple might use one to state that property passes to the surviving spouse, followed by their children after the second spouse dies.

That sounds straightforward.

However, each spouse still has their own estate, property interests, beneficiaries, and planning decisions. Combining those decisions into one document can create questions when circumstances change.

Michigan courts have also distinguished reciprocal estate planning from an enforceable agreement between spouses. Identical or reciprocal wills alone do not necessarily establish a contract to make, or refrain from changing, a will.

That distinction becomes important when comparing a joint will vs mutual will or deciding whether separate wills would better protect each spouse.

How Does a Joint Will Work After the First Spouse Dies?

Suppose a married couple has two children. Their joint will states that when one spouse dies, the surviving spouse receives the estate. After the survivor dies, everything remaining goes equally to the children.

The arrangement appears easy while both spouses are alive.

The harder questions often come later.

What happens if the survivor remarries? What if one child develops financial problems? What if the surviving spouse wants to help a grandchild or sell an asset mentioned in the original estate plan?

The answers depend heavily on how the documents were drafted and whether a contractual obligation exists.

A joint will attorney can examine whether the couple’s goals are better accomplished through separate wills, trusts, beneficiary arrangements, or another estate planning structure.

Joint Will vs Mutual Will: What Is the Difference?

The terms are sometimes used interchangeably, but they can describe different concepts.

A joint will generally refers to a single testamentary document executed by two people. Mutual or reciprocal wills usually involve separate wills containing corresponding provisions.

The more important issue is whether the spouses intended to create a binding contract concerning their wills.

Michigan case law makes this distinction particularly important. Michigan courts have recognized that identical and reciprocal provisions do not, standing alone, prove that spouses contracted not to change their wills. (Michigan Bar Association)

Therefore, a joint will vs mutual will comparison should look beyond whether the documents contain similar instructions.

Couples need to understand whether their arrangement remains changeable and what happens after the first spouse dies.

Why Can a Joint Will Become a Problem After One Spouse Dies?

Estate plans need room to respond to real life.

Imagine a husband dies at 65 and his wife lives another 25 years. During those years, she may sell their home, acquire different investments, become a grandparent, remarry, or experience major changes within the family.

An estate plan created decades earlier may no longer reflect those circumstances.

If the couple’s arrangement creates enforceable contractual obligations, the surviving spouse may face restrictions or disputes when trying to change the ultimate distribution.

On the other hand, if the couple believed the arrangement was binding when it was not, the opposite problem can occur. The first spouse’s expectations about the final beneficiaries may not be protected.

That uncertainty is one reason couples estate planning Michigan families undertake should focus on long-term flexibility rather than simply reducing the number of documents signed today.

What Happens If the Surviving Spouse Remarries?

Remarriage can significantly change an estate plan.

Suppose spouses create an arrangement expecting their property eventually to pass to their two children. One spouse dies, and the survivor later remarries.

The surviving spouse may now have a new spouse, additional financial responsibilities, different property, and possibly stepchildren.

Michigan law also gives surviving spouses important rights within estate administration. Those rights can interact with an existing estate plan in ways a couple may not have anticipated years earlier.

A joint will Michigan couple created during their first marriage may therefore become poorly suited to the surviving spouse’s new circumstances.

An estate planning attorney Michigan couples consult can plan for remarriage and other future changes before they become actual problems.

Joint Wills Can Be Especially Difficult for Blended Families

Blended families add another layer of complexity.

Consider a husband with two children from a previous marriage and a wife with one child from hers. Both spouses may want to provide for each other while also protecting an inheritance for their respective children.

A simple joint arrangement may struggle to balance those goals.

If everything passes outright to the surviving spouse, the survivor may eventually control where those assets go. If the arrangement instead attempts to restrict future changes, the surviving spouse may lose flexibility needed later in life.

Neither result is automatically right or wrong. The appropriate structure depends on what both spouses are actually trying to protect.

Michigan’s own statutory will guidance recommends consulting an attorney when someone has children from a prior relationship or wants more sophisticated trust planning. (Michigan Legislature)

For blended families, separate wills combined with appropriate trust planning may provide more precise control than a single joint document.

Separate Wills Do Not Mean Separate Estate Plans

This point causes unnecessary confusion.

A married couple can have one coordinated estate plan without sharing one will.

Each spouse can execute an individual will while coordinating beneficiaries, guardianship wishes, personal representatives, trusts, and other provisions with the other spouse.

That approach gives each person a legally distinct document.

It also creates room to address differences between their assets. One spouse might own a business interest while the other owns inherited property.

One may have children from an earlier relationship. Their beneficiary designations may also differ.

Michigan’s statutory will itself is structured as an individual document. It identifies the testator, spouse, children, distributions, and personal representative for that individual. (Michigan Legislature)

A joint will attorney can explain when coordinated individual wills offer a cleaner solution.

A Will Does Not Control Every Asset a Couple Owns

Whether spouses use joint or separate wills, they should understand what a will actually controls.

Michigan’s statutory will notice expressly states that the will does not affect certain jointly held assets, retirement benefits, or life insurance when an effective beneficiary survives the person who died. (Michigan Legislature)

This matters because married couples frequently own property jointly.

A house, bank account, retirement plan, or insurance policy may pass through its ownership structure or beneficiary designation instead of through the will.

Michigan also applies specific survivorship rules to jointly owned property when the order of death cannot be established.

(Michigan Legislature)

Good couples estate planning Michigan residents pursue should therefore review asset ownership alongside the wills themselves.

When Might Couples Need More Than Two Simple Wills?

Separate wills solve the problem of putting two people’s wishes into one document, but they are not always the entire solution.

Some couples need greater control over what happens after the first spouse dies.

A trust may be useful when spouses want to provide for the survivor while preserving assets for children or other beneficiaries. Trust planning can also address how property should be managed rather than simply naming who eventually receives it.

Business ownership, substantial assets, property outside Michigan, children from previous relationships, and beneficiaries who need financial protection can all justify more detailed planning. Michigan’s official guidance specifically identifies several of these situations as reasons to seek legal advice rather than relying on the basic statutory will. (Michigan Legislature)

An estate planning attorney Michigan couples work with can determine whether individual wills are enough or whether a trust belongs in the plan.

Should Michigan Couples Use a Joint Will?

For many couples, the attraction of a joint will is simplicity. Both spouses agree today, so putting those wishes into one document feels logical.

The problem is not necessarily what the couple wants today.

It is what could change tomorrow.

A spouse can live decades after the other dies. Children grow older. Relationships change. Property gets sold. New assets are acquired.

Grandchildren arrive. Businesses change hands, and remarriage can create an entirely different family structure.

A joint will Michigan couples consider should therefore be evaluated against those possibilities.

Separate wills can still express matching wishes while allowing each spouse to maintain an individual estate plan. Trusts can provide additional control when the couple needs more than simple distributions.

Talk to a Michigan Estate Planning Attorney Before Combining Your Wills

So, what is a joint will? It is generally one will expressing the testamentary wishes of two people. The more important question is whether putting two estate plans into one document actually helps the couple.

For many Michigan spouses, flexibility matters more than having fewer documents.

Before choosing a joint arrangement, couples should understand what happens after the first death, whether either spouse can change the plan, how remarriage could affect it, and whether children from previous relationships need additional protection.

A joint will attorney can review those questions before anything is signed. An estate planning attorney Michigan couples work with can also compare individual wills, trusts, and other options based on how the family actually owns its property.

The goal should not be to create the simplest document today. It should be to create an estate plan that still works when life no longer looks the way it does today.
