Yes, each spouse should have a separate will. Married couples are better served by two individual wills than by any single shared document, because separate wills let each person control their own property, name their own executor and guardian preferences, and update their plan independently as circumstances change. Most estate planning attorneys strongly advise against a single joint document for exactly these reasons.
Why Two Wills Work Better Than One
Marriage doesn’t merge two people into one legal identity for estate planning purposes. Each spouse typically owns some assets individually and shares others jointly. A separate will gives each person the ability to direct where their individual property goes, whether that’s assets owned before the marriage, an inheritance from a family member, or a gift received during the marriage. Without a will of their own, those wishes have no legal weight.
Independent documents also handle the unpredictable parts of life better than any shared arrangement. If one spouse dies and the survivor remarries, has additional children, or changes their mind about who should inherit certain property, the survivor’s own will can be revised without restriction. Each spouse can name a different executor if that fits their situation, and each can express specific preferences about guardianship for minor children. The two wills work in parallel but remain fully independent.
That independence extends to timing. Either spouse can revisit and update their document on their own schedule without needing the other’s consent or involvement. A shared document, by contrast, ties changes to both signatures and, depending on how it’s drafted, can lock the survivor into terms that no longer make sense after the first death.
Mirror Wills, Mutual Wills, and Joint Wills
Three terms come up frequently when couples discuss estate planning together, and they’re easy to confuse. Each carries different legal consequences.
Mirror Wills
Mirror wills are two separate documents that happen to contain nearly identical terms. Each spouse signs their own will, and both typically leave everything to the surviving spouse first, then to the same set of beneficiaries. Because these are independent documents, either spouse can revise or revoke their will at any time, including after the other spouse dies. The tradeoff is that the surviving spouse has no legal obligation to keep the original terms. If protecting a specific inheritance path for children matters more than flexibility, mirror wills alone may not accomplish that.
Mutual Wills
Mutual wills include a binding agreement between the spouses that neither will change the terms without the other’s consent. After the first spouse dies, the survivor is locked into the agreed-upon distribution plan. Couples with children from prior relationships sometimes use mutual wills to guarantee those children ultimately inherit. The rigidity can become a serious problem, though. If the surviving spouse’s financial situation changes dramatically, they may be stuck with terms that no longer make sense and have no legal way to adjust them.
Joint Wills
A joint will is a single document signed by both spouses. Technically it operates as a separate distribution of each person’s property, but it’s executed in one instrument rather than two. Many people assume a joint will automatically becomes irrevocable after the first death, but that characteristic actually belongs to mutual wills. A joint will by itself is not inherently intended to be irrevocable or to express a mutual intention.1Wikipedia. Joint Wills and Mutual Wills Courts in different jurisdictions interpret joint wills inconsistently, and some may treat the document as carrying an implied mutual agreement. That ambiguity alone is reason enough to avoid them. Two separate wills eliminate the risk entirely.
What Each Spouse’s Will Should Cover
Every will should address several core decisions. Many spouses make similar choices, but the ability to tailor each document independently is what makes two wills valuable.
- Guardian for minor children. Name the person you want to raise your children if both parents die. Spouses often agree, but each should state the preference in their own will. If the two wills name different people and both parents die at once, the court decides, so coordinating matters.
- Beneficiaries. Specify who receives each asset, including individual property and your share of jointly owned property that doesn’t pass automatically by survivorship.
- Executor. Choose the person responsible for managing your estate, paying debts, and distributing assets according to the will’s terms. Many spouses name each other as primary executor with a backup in case the surviving spouse is unable or unwilling to serve.
- Specific bequests. Identify particular items, sums of money, or charitable gifts you want directed to specific people or organizations.
- Contingency plans. Address what happens if a named beneficiary, guardian, or executor dies before you do. Without backup designations, the court fills the gap.
- Bond waiver. Most states require an executor to post a surety bond as a financial guarantee that they’ll administer the estate properly. Your will can waive this requirement, saving the estate the cost of the premium. This waiver is especially common when the executor is a surviving spouse who is also the primary beneficiary.
Drafting a standard will with an attorney typically ranges from $200 to $1,500 per person, depending on the complexity of your estate and where you live. For a married couple, that means budgeting for two documents. The expense is modest compared to the cost of probate litigation or an intestacy outcome that sends assets in directions nobody intended.
Assets Your Will Won’t Control
Not everything you own is controlled by your will, and married couples are especially likely to hold assets that transfer automatically no matter what any will says. Understanding which assets bypass your will is as important as drafting the will itself, because a mismatch between your will and your beneficiary designations can produce results nobody intended.
Property held in joint tenancy with right of survivorship passes directly to the surviving owner when one owner dies. This happens automatically and overrides any contrary instructions in a will. Married couples commonly hold real estate, bank accounts, and investment accounts this way. The transfer skips probate, but it also means your will has zero effect on that property.
Retirement accounts like 401(k) plans and IRAs, life insurance policies, annuities, and accounts with payable-on-death or transfer-on-death designations all transfer to whoever is named as the beneficiary on the account, not whoever is named in the will. If your will says your retirement account goes to your children but the account’s beneficiary form still names your spouse, the spouse receives it. The beneficiary designation wins every time. Reviewing these designations whenever you update your will keeps the two from working at cross purposes.
You Generally Can’t Fully Disinherit a Spouse
Even with a valid will, you generally cannot completely disinherit your spouse. Most states give a surviving spouse the right to claim an “elective share” of the deceased spouse’s estate regardless of what the will says. The traditional fraction is one-third of the probate estate, though the exact percentage varies by state.2Legal Information Institute. Elective Share
This matters for couples drafting separate wills because it sets a floor on what the surviving spouse can receive. If one spouse’s will leaves everything to children from a prior marriage, the surviving spouse can elect against the will and claim the statutory share instead. Couples should account for this right when deciding how to allocate assets in their individual wills, particularly in blended family situations where the interests of a surviving spouse and stepchildren may conflict.
In the nine community property states, a different framework applies. Each spouse already owns half of all property acquired during the marriage, so each spouse’s will can only direct what happens to their own half. The surviving spouse’s half is never at risk regardless of what the deceased spouse’s will says.
When to Update Your Will
Creating a will is not a one-time event, and this is another reason two documents work better than any shared arrangement. Each spouse can update their own will on their own timeline.
Review your will whenever a major life event occurs, and at a minimum every three to five years even if nothing dramatic has changed. Events that should trigger a review include:
- Marriage, divorce, or remarriage, which fundamentally change your family structure and likely your intended beneficiaries.
- Birth or adoption of a child or grandchild, which brings new family members who need to be accounted for, especially in guardianship provisions.
- Death or incapacity of a named beneficiary, executor, or guardian, so that backup designations move up and any gaps get filled.
- Significant financial changes such as selling a business, receiving an inheritance, or acquiring major assets.
- Changes in tax law that affect how married couples structure their estate plans.
Each review is an opportunity for each spouse to make sure their own will still reflects what they want. That’s the practical payoff of drafting two documents instead of one: the plan can move with your life, not against it.
