Dying without a will is known as dying intestate. Massachusetts law provides a default inheritance structure based on the relatives who survive you. Beneficiary designations, certain forms of joint ownership, and assets held in trust can still pass outside that process, which is why the complete estate plan matters more than the will alone.
How Massachusetts Intestate Succession Works
Massachusetts intestate succession rules determine who inherits the portion of an estate that does not pass under a valid will or another legally effective transfer arrangement. The surviving spouse’s share depends on whether the decedent leaves descendants, parents, or descendants from another relationship.
Who Inherits If There Is No Will?
The table below summarizes several common Massachusetts intestacy scenarios. Actual family structures can be more complicated, so the statute and an estate planning attorney should be consulted before relying on a simplified example.
| Surviving family | Surviving spouse receives | Who receives the balance |
|---|---|---|
| Spouse; no descendants or parents | The entire intestate estate | None |
| Spouse and only shared descendants; spouse has no other surviving descendants | The entire intestate estate | None |
| Spouse and parent or parents; no descendants | The first $200,000 plus 3/4 of the remaining balance | The decedent’s parent or parents receive the remaining 1/4 |
| Spouse and shared descendants; spouse also has surviving descendants from another relationship | The first $100,000 plus 1/2 of the remaining balance | The decedent’s descendants receive the remaining share under Massachusetts representation rules |
| Spouse and at least one descendant who is not also the spouse’s descendant | The first $100,000 plus 1/2 of the remaining balance | The decedent’s descendants receive the remaining share under Massachusetts representation rules |
| No spouse; descendants survive | No spouse | The descendants inherit the intestate estate per capita at each generation |
| No spouse or descendants; parent or parents survive | No spouse | The parents inherit equally if both survive, or the surviving parent inherits the estate |
| No spouse, descendants, or parents | No spouse | The estate passes next to descendants of the decedent’s parents, then to other next of kin under the statutory order |

Which Assets Are Actually Affected?
Intestacy rules apply to assets that become part of the probate estate. Other assets may pass according to a beneficiary designation, trust terms, or the form of ownership instead.
Common Probate Assets
- Assets owned individually with no beneficiary designation
- Individually owned real estate without another effective transfer arrangement
- Accounts or property that do not pass automatically to a surviving joint owner or named beneficiary
Assets That Often Bypass Probate
- Assets held in a properly funded trust
- Life insurance with a valid beneficiary designation
- Retirement accounts with valid beneficiary designations
- Property held with rights of survivorship
- Accounts with an effective payable-on-death or transfer-on-death designation
That distinction matters. A will generally does not override a beneficiary designation or another transfer arrangement that controls an asset outside the probate estate.
Where Intestacy Can Create Problems
Massachusetts law provides an orderly default, but a statutory default cannot take into account every family’s relationships, priorities, or financial plan.
Six areas where the default may not fit
Less Control Over Distribution
Probate assets pass according to the statutory family hierarchy rather than according to personal preferences that were never documented.
Blended-Family Complexity
Different rules can apply when either spouse has descendants from another relationship, which can produce an allocation the family did not expect.
No Automatic Gifts to Friends or Charities
People or organizations outside the statutory line of inheritance generally will not receive probate assets simply because the decedent intended to provide for them.
Less Choice Over Estate Administration
Without a valid nomination in a will, Massachusetts law determines priority among people seeking appointment as personal representative.
Minor Beneficiaries Need Additional Planning
An inheritance for a minor can create separate property-management issues, including the possible need for a conservator or another protective arrangement.
More Room for Family Uncertainty
When intentions were never documented, relatives may be left to interpret what the decedent would have wanted while also navigating the legal process.
Dying without a will does not, by itself, determine whether Massachusetts estate tax is due. Under current Massachusetts law, the estate tax is imposed on the value of the decedent’s estate before distribution to beneficiaries. For deaths on or after January 1, 2023, a Massachusetts estate tax return is generally required when the gross estate plus adjusted taxable gifts exceeds $2 million.
A will is an important estate-planning document, but a will by itself is not a complete tax strategy. For estates that may approach or exceed the Massachusetts filing threshold, tax considerations should be coordinated with an estate planning attorney, tax professional, and financial advisor.
Minor Children: What a Will Does and Does Not Do
Planning for minor children is one of the strongest reasons to document your wishes, but Massachusetts law is more nuanced than saying that a parent who dies without a will automatically loses all say over guardianship.
A Parent Can Nominate a Guardian
Massachusetts law allows a parent to appoint a guardian for a minor child by will or by another writing signed by the parent and attested by at least two witnesses. A will is therefore one common way to document the choice, but it is not the only method recognized by statute.
A Surviving Parent’s Rights Still Matter
A parental guardian appointment does not supersede the parental rights of the other parent. When a court appointment is required, Massachusetts courts consider the statutory requirements and the minor’s welfare and best interests.
Guardianship and Inheritance Management Are Different
A guardian generally has responsibilities related to the child’s support, care, education, health, and welfare. If a minor owns money or property that requires management or protection that cannot otherwise be provided, a court may appoint a conservator or enter another protective order.

Special Family Situations Under Massachusetts Law
Intestacy rules also contain details that can matter in less traditional or multigenerational families:
- Children born outside marriage: For intestate succession, Massachusetts law generally treats an individual as the child of the individual’s natural parents regardless of the parents’ marital status, with the parent-child relationship established under applicable law.
- Adopted children: Adopted children generally inherit as children of their adoptive parents. Massachusetts law includes additional rules for certain stepparent and relative adoptions.
- Children conceived before death: An individual in gestation at the relevant time is treated as living at that time if the individual survives at least 120 hours after birth.
- Stepchildren and foster children: A stepchild or foster child does not inherit as a child solely because of that relationship. Adoption or another legally recognized relationship may change the result.
- If there is no statutory heir: If no person is entitled to inherit under the intestacy statutes, the intestate estate generally passes to the Commonwealth of Massachusetts, subject to the statutory rules in M.G.L. c. 190B, § 2-105.

What a Will Can Actually Do
A will gives you a way to document choices that Massachusetts intestacy law otherwise makes for you.
- Direct how probate assets should be distributed, subject to applicable law
- Nominate a personal representative to administer the estate
- Nominate a guardian for minor children
- Leave probate assets to friends, charities, or other beneficiaries outside the default intestacy hierarchy
- Create testamentary trusts or other provisions for beneficiaries when appropriate
A will still needs to be coordinated with beneficiary designations, account ownership, trusts, powers of attorney, health care documents, and tax planning. For many Massachusetts households, especially those with substantial retirement assets, real estate, or a taxable estate, those pieces are interconnected.
Taking the Next Step
Estate planning is legal work, so the documents themselves should be prepared or reviewed by a qualified estate planning attorney. A financial advisor can help coordinate the financial side of the plan by identifying accounts and beneficiary designations, modeling the financial implications of potential transfer scenarios, identifying tax and cash-flow considerations, and working with the attorney and tax professional so the pieces fit together.
The goal is not simply to avoid intestacy. It is to make sure the plan reflects the people, responsibilities, and financial decisions that matter to your family.
Coordinate the Pieces of Your Estate Plan
A will is one part of an estate plan. Beneficiary designations, account titling, trusts, powers of attorney, health care directives, and tax planning can all affect how the plan works in practice.
