When a Massachusetts resident dies without a valid will, the question is not whether the estate will be distributed, but who the law identifies as the heirs. The Commonwealth’s default rules can produce a result that differs sharply from the person’s wishes. Especially when a family includes a surviving spouse, children from different relationships, or living parents.
Massachusetts intestate succession is the legal process for distributing property when someone dies without a valid will. Under Mass. Gen. Laws Ch. 190B, the Massachusetts Uniform Probate Code determines which relatives inherit and how much they receive, rather than allowing the family to choose the distribution.
The outcome depends on the surviving family members and the type of relationship each had with the person who died. Whether the estate goes entirely to a spouse, is split between a spouse and children. Or passes to parents and more distant relatives depends on a set of statutory formulas the decedent never chose.
These formulas apply automatically to any probate asset owned solely in the decedent’s name, and under Massachusetts law real property and personal property are treated the same way. That is why so many estate planning attorneys encourage Massachusetts residents to plan ahead. A valid will replaces the state’s default plan with one you write yourself, letting you choose your heirs. Name your own fiduciary, and avoid the delays and uncertainty that can accompany an intestate estate.
The sections below explain how intestate succession works in Massachusetts, who inherits in common family situations, and what the probate process involves when no will exists.
What Is Massachusetts Intestate Succession?
Intestate succession is the legal process that determines how a person’s probate property is distributed after death when the person leaves no valid will. In Massachusetts, these default inheritance rules are found in Mass. Gen. Laws Ch. 190B, the Massachusetts Uniform Probate Code. Rather than allowing the family to decide informally, the law identifies the relatives who may inherit and establishes the order and shares that apply.
In plain English, Massachusetts intestate succession is the Commonwealth’s default estate plan. It steps in when a will is missing or when a will does not effectively dispose of part of an estate. The rules are designed to provide a workable process, including for people of modest means who have not created a formal plan. They may still distribute property differently from what the person would have wanted.
What does intestacy mean?
Intestacy means dying without a valid will that controls the property at issue. A person may be completely intestate if there is no will at all, or partially intestate if a will addresses some property but leaves other property undisposed of. Under Massachusetts law, any part of an estate that is not effectively disposed of by a will passes to the decedent’s heirs under the intestate succession rules. See Mass. Gen. Laws Ch. 190B, Sec. 2-101.
Intestacy does not necessarily mean that every asset a person owned will be divided through probate. Some assets may pass according to a beneficiary designation, joint ownership arrangement, or another transfer mechanism. The intestate rules generally concern property that remains part of the probate estate. Determining which assets are subject to probate is therefore an important first step in understanding what the default formulas will actually control.
How does the Massachusetts Uniform Probate Code work?
Article II, Part 1 of the Massachusetts Uniform Probate Code provides the basic pattern for intestate succession. The law looks primarily at the decedent’s family relationships, including whether a spouse, descendants, parents, or other relatives survive. The surviving spouse’s share, for example, can change depending on whether the decedent has children and whether those children are also the spouse’s descendants. Later sections explain those different scenarios in more detail.
The code also treats real property and personal property under the same intestate distribution framework. That means the law does not use one inheritance pattern for land and another for personal belongings simply because the assets have different legal classifications. The Massachusetts Department of Revenue’s commentary explains this approach in its discussion of Article II, Part 1.
These default rules can be useful, but they are not individualized planning. They may not account for a blended family, an unmarried partner, a dependent with special needs. A charitable intention, or a wish to leave property to a particular person. Creating a valid will and a broader estate planning strategy allows a person to make those choices directly instead of leaving them to statutory formulas.
How Massachusetts Divides an Estate Without a Will
When a Massachusetts resident dies without a valid will, intestate succession determines which relatives inherit property that passes through the probate estate. The surviving spouse is considered first, but the spouse’s share depends on the decedent’s surviving descendants and parents. Massachusetts law treats real and personal property under the same intestate distribution framework. See the Massachusetts Uniform Probate Code commentary.
Surviving spouse shares
Under Massachusetts General Laws chapter 190B, section 2-102, these are the principal surviving-spouse scenarios:
| Family situation | Surviving spouse’s intestate share |
|---|---|
| No surviving descendant or parent of the decedent | The entire intestate estate |
| No surviving descendant, but a parent of the decedent survives | The first $200,000, plus three-fourths of the remaining balance |
| All surviving descendants are also the spouse’s descendants, and the spouse has no other surviving descendants | The entire intestate estate |
| The spouse has other descendants, or at least one surviving descendant is not the spouse’s descendant | The first $100,000, plus one-half of the remaining balance |
The last scenario can apply in a blended family, including when the decedent has a child from another relationship. The law reserves part of the intestate estate for the decedent’s descendants rather than automatically giving everything to the spouse. The exact result depends on the family relationships that exist when the decedent dies, not simply on whether the couple was married.
Who inherits after the spouse’s share?
If there is no surviving spouse, or if part of the estate remains after the spouse’s statutory share, Massachusetts intestate succession follows a family hierarchy. The decedent’s children generally inherit before more remote relatives. If a child has already died, that child’s descendants may inherit through the applicable representation rules. If there are no eligible descendants, surviving parents are next in line.
When neither descendants nor parents survive, the law turns to siblings and their descendants. If that group is also absent, the search extends to grandparents and relatives on the relevant sides of the family. These rules are intended to provide a default estate plan, but the result may not match the decedent’s actual wishes. For a closer look at what happens when there are no eligible heirs, review the related guidance from O’Connell Law.
If no qualifying heir can be identified, the estate ultimately passes to the Commonwealth of Massachusetts through escheat. That outcome is uncommon, but it underscores why identifying heirs and reviewing beneficiary designations matters during estate planning.
The Surviving Spouse’s Elective Share in Massachusetts
A surviving spouse may have rights that are different from the share assigned under Massachusetts intestate succession. The elective share is a separate statutory protection under the Massachusetts Uniform Probate Code, specifically Article II, Part 2. It can become important when a valid will leaves a spouse less than the law allows, or attempts to leave the spouse nothing.
This right is not the same as the intestate share described above. The intestate share is the portion a spouse receives when the decedent leaves no valid will, or when some property is not effectively disposed of by the will. The elective share, by contrast, gives a surviving spouse a potential statutory choice in response to the estate plan created by the decedent’s will. The governing provisions appear in Massachusetts General Laws Chapter 190B, Article II.
When the elective share may matter
Consider a person who signs a will leaving most or all probate assets to children, other relatives, or charitable organizations. If the person is married at death, the surviving spouse may not be limited to accepting the will’s terms. Depending on the circumstances, the spouse may be able to claim the statutory elective share instead. The calculation and legal effect depend on the statute, the estate, the marital relationship, and the assets included in the relevant estate calculation.
That distinction is especially important in blended families. A decedent’s intestate share may change based on whether surviving descendants are also descendants of the spouse. On whether the spouse has children from another relationship, and on whether the decedent’s parents survive. Those default scenarios do not answer every question raised by a will that disinherits or under-provides for a spouse. A spouse’s elective-share rights must be analyzed separately under Article II, Part 2.
Electing is a legal decision, not an automatic distribution
An elective share does not necessarily appear automatically in the spouse’s hands when the estate is opened. The surviving spouse generally must make a timely election and follow the required probate procedure. Missing a deadline, misunderstanding which assets are relevant, or assuming that every asset is part of the probate estate can affect the result.
Because the elective share and intestate share operate under different rules. A surviving spouse should not rely on a simple percentage or a quick comparison of the will and the estate inventory. Reviewing the will, beneficiary designations, jointly owned property, trusts, and probate filings can help determine which rights and deadlines apply.
The Probate Process for Intestate Estates in Massachusetts
Dying without a will does not avoid probate in Massachusetts. Property that is owned solely in the decedent’s name generally must be addressed through the Massachusetts Probate and Family Court before it can be transferred to heirs. The case is commonly handled as an administration proceeding, including an informal probate process when the circumstances permit. The court-supervised process identifies the person authorized to act, establishes what belongs to the probate estate. Addresses valid debts and claims, and applies Massachusetts intestate succession rules to whatever remains.
Not every asset necessarily goes through probate. Jointly held property, property held in a trust, and accounts or policies with effective beneficiary designations may pass outside the probate estate. The distinction matters because intestate succession generally controls only property that passes through probate. Massachusetts law also applies the same intestate distribution framework to real and personal property rather than creating separate inheritance patterns for each type. Massachusetts Probate Code commentary explains this approach.
- Open the probate case. A person with an interest in the estate usually begins the process by filing the required petition and supporting documents with the appropriate Massachusetts Probate and Family Court. The filing identifies the decedent, establishes that the person has died, and provides information about known heirs and the property that may require administration. The court then determines whether the matter can proceed under the applicable probate procedure. Because there is no will to submit, the case is governed by the Massachusetts Uniform Probate Code and the court’s procedural requirements.
- Appoint a personal representative. In a testate estate, a will may nominate the person who will serve as fiduciary. In an intestate estate, the court appoints a personal representative, often called an administrator, under the statutory priority rules. The administrator is responsible for acting for the estate, protecting estate property, keeping records, and carrying out the court-authorized administration. This is an important practical difference: without a will, the decedent did not select the fiduciary in advance. So family members may face uncertainty or disagreement about who should serve.
- Identify and inventory probate assets. The administrator gathers information about property owned in the decedent’s sole name, including real estate, bank accounts, investments, personal property, and other interests. The administrator also determines how each asset was owned and whether it has a surviving joint owner, trust ownership, or beneficiary designation. Solely owned assets generally belong in the probate analysis, while an effective joint ownership or beneficiary arrangement may transfer an asset outside probate. The inventory is necessary before the administrator can determine what is available for debts and eventual distribution.
- Notify creditors and heirs. The administrator provides required notices and communicates with interested people, including heirs identified under Massachusetts intestacy law. Creditors may submit claims subject to the applicable rules and deadlines. Heirs should receive accurate information about the proceeding and the proposed administration. Disputes about ownership, creditor claims, or the identity of heirs may require additional filings or court involvement, which can make an intestate estate more difficult to resolve.
- Pay valid debts and administration expenses. Before distributing property to heirs, the administrator uses estate assets to address allowable debts, taxes, expenses of administration, and other obligations in the order required by law. The administrator should not distribute the estate prematurely. A careful accounting of claims and available assets helps prevent an heir from receiving property that later must be returned to satisfy an approved obligation.
- Distribute the remaining estate under intestate succession. After debts and expenses are resolved, the administrator distributes the remaining probate property to the heirs determined by Massachusetts law. The result depends on the decedent’s surviving spouse, descendants, parents, and other relatives. The distribution may not reflect what the decedent would have chosen. A valid will could have named the preferred fiduciary and provided specific instructions, reducing the uncertainty created by the default Massachusetts intestate succession plan.
Probate is therefore not merely a filing step. It is the legal framework that determines who may act, what property is available, which obligations must be paid, and who ultimately receives the balance. The details of ownership and family relationships can materially change the outcome.
Why Dying Without a Will Leaves Your Legacy to State Rules
Intestacy is the legal framework that determines who receives probate property when someone dies without a valid will. In Massachusetts, the Massachusetts Uniform Probate Code supplies a default plan. That plan is designed to provide a workable answer when no individual plan exists. But it cannot account for the relationships, promises, and priorities that made a person’s life unique.
The Commonwealth’s own commentary recognizes that these prescribed patterns may sometimes defeat a decedent’s intent. Without a will, the law does not ask who you trusted most, who provided years of care, or which causes mattered to you. It applies the statutory formula to the assets that pass through probate. Massachusetts intestate succession therefore functions as a one-size-fits-all estate plan, not a personal expression of your wishes.
Relationships the formula may not recognize
Several common family and household arrangements can produce results that feel surprising or unfair:
- An unmarried partner may inherit nothing. A long-term partner who shared a home, expenses, and caregiving responsibilities generally does not receive an intestate share simply because the relationship was committed. Without a will or another effective plan, property may pass to relatives instead.
- A blended family may receive an unexpected split. The surviving spouse’s share can change depending on whether the children are also the spouse’s children and whether the spouse has children from another relationship. The statutory categories may not reflect how the family actually functions or what the decedent intended for each child.
- A person supported for years may be left out. A close friend, stepchild, caregiver, or other person who relied on the decedent may not fit the legal definition of an heir. The law focuses on family relationships recognized by statute, not necessarily on dependence or emotional closeness.
- Estranged relatives may receive property. If there is no qualifying spouse, child, or parent who takes under the applicable rule, the estate can move to more distant relatives. A friend, charitable organization, or community cause that mattered deeply to the decedent receives nothing unless the person made an effective plan.
A will gives you a chance to make the decision
A will cannot eliminate every estate-administration issue, and it must be properly prepared and executed. It can, however, identify beneficiaries, name a personal representative, and express choices that the default rules cannot. A thoughtful estate planning process can also coordinate beneficiary designations and other planning tools with the will.
Because disagreements can still arise after death, understanding estate planning and how wills can be contested is part of making a durable plan. The questions below address several concerns Massachusetts families commonly have before deciding what steps to take.
Frequently Asked Questions
What happens if you die without a will in Massachusetts?
The Massachusetts Uniform Probate Code supplies the default rules for distributing property when someone dies without a valid will. The estate generally passes to heirs identified by law, which may not match the person’s wishes. See Massachusetts’ intestacy guidance.
Who inherits under Massachusetts intestate succession laws?
Inheritance depends on the surviving family. A spouse’s share changes based on whether the decedent leaves descendants, whether those descendants are also the spouse’s children, and whether the spouse has children from another relationship. If there is no surviving spouse, descendants, parents, and more distant relatives may inherit in the order provided by Massachusetts law.
What assets are affected by intestacy in Massachusetts?
Intestate succession generally applies to assets that pass through probate, such as property owned solely in the decedent’s name. Assets with a valid beneficiary designation or survivorship arrangement may pass outside probate instead. Massachusetts law does not distinguish between real and personal property when determining intestate distribution. See Article II commentary.
How much does a spouse inherit under Massachusetts intestacy laws?
There is no single answer. If no descendant or parent survives, the spouse receives the entire intestate estate. If descendants from another relationship survive, the spouse receives the first $100,000 plus one-half of the remaining balance. Other family circumstances can produce a different share under Massachusetts General Laws chapter 190B, section 2-102.
Plan Ahead So Massachusetts Intestate Succession Rules Do Not Decide for You
Intestate succession is designed to work as a default estate plan, but it rarely matches what a family would have chosen on its own. A valid will lets you name who inherits, who will serve as your personal representative, and how your property should be handled. The same planning work also gives you a chance to address Powers of Attorney, healthcare directives, and other documents that matter as life changes.
