At a glance
| Governing law and covered interests | Massachusetts Uniform Probate Code, G.L. c. 190B, § 2-801; covers present, future, contingent, fractional, real/personal, and power interests passing by intestacy, will, trust, insurance/annuity, joint tenancy/tenancy by the entirety, power of appointment, other instruments, or law |
|---|---|
| Whole, partial, and conditional disclaimer | Whole or partial, including a fractional part, share, portion, or specific asset. A bar affecting one accepted or transferred part does not bar disclaimer of another part. Section 2-801 requires a clear and unequivocal disclaimer and states no general conditional-disclaimer rule. |
| Writing or record and required contents | Writing required; must describe the interest, declare the disclaimer and its extent, be clear and unequivocal, and be signed. File the original, or an attested copy when more than one probate court requires filing; no express electronic-record route appears in § 2-801. |
| Signature, witnesses, acknowledgment, and notary | Signed by the beneficiary; no general witness or acknowledgment requirement for personal property. A real-property disclaimer must be acknowledged in the manner used for deeds; § 2-801 does not make notarization universal. |
| State deadline, irrevocability, and federal-tax overlay | Execute and file within 9 months after final ascertainment plus indefeasible vesting; survivorship property uses 9 months after the other tenant's death. A court may extend the state period on petition. Irrevocable upon compliant execution and filing. Federal § 2518 uses a separate 9-month receipt clock and tax conditions. |
| Delivery, filing, and recipient | File the original (or attested copies if multiple courts) with the probate court(s), if any, where the fiduciary controlling the property files periodic accounts. Serve a copy by hand or certified mail to the last known address of each custodian/possessor; service failure does not invalidate the disclaimer. |
| Real-property recording and notice | Realty disclaimer must be deed-style acknowledged. For effect beyond the beneficiary, the beneficiary's heirs/devisees, and persons with actual notice, record the original or attested copy in the county/district registry of deeds, or file/register it with the assistant recorder for registered land. |
| Acceptance, transfer, insolvency, and creditor bars | Barred as to the affected part by assignment/conveyance/encumbrance/pledge/transfer/other disposition or contract, judicial disposition, insolvency, signed written waiver, or acceptance; knowingly receiving a benefit without objection is acceptance. The statute applies specified fraudulent-transfer provisions to insolvency as if the disclaimer were a conveyance. |
| Effective date and destination | Effective according to its terms and irrevocable on execution plus filing. A disclaimed power is extinguished; otherwise, unless that result substantially impairs the governing instrument, statute, or rule, the interest passes as if the beneficiary died immediately before final ascertainment and indefeasible vesting and never vests in the beneficiary. |
Requirements one by one
Governing law and covered interests
Massachusetts places its disclaimer rules in the Massachusetts Uniform Probate Code, G.L. c. 190B, § 2-801. The section reaches present, future, contingent, fractional, real, personal, and power interests. Its listed sources include intestacy, wills, testamentary and inter vivos trusts, insurance and annuity contracts, joint tenancy, tenancy by the entirety, powers of appointment, other instruments, and rules of law.
Whole, partial, and conditional disclaimer
The definition covers a fractional part, share, portion, or specific asset. Subsection (h) adds an important partial-interest rule: acceptance, transfer, waiver, or another listed bar affecting one part “shall not bar the right to disclaim any other part.” Section 2-801 requires the disclaimer to be clear and unequivocal and does not state a general conditional-disclaimer route.
Writing or record and required contents
Under § 2-801(d), the document must be in writing, describe the interest, declare the disclaimer and its extent, be clear and unequivocal, and be signed. Section 2-801(e) (§ 2-801(e)) requires the original for court filing, except that an attested copy may be used when filing is required in more than one probate court. The section does not expressly provide an electronic-record alternative.
Signature, witnesses, acknowledgment, and notary
The beneficiary signs. Section 2-801(d) states no general witness, acknowledgment, or notary requirement. Real property is different: subsection (e) requires a disclaimer of a real-property interest to be acknowledged in the manner provided for deeds.
State deadline, irrevocability, and federal-tax overlay
Massachusetts generally measures nine months from the event that finally ascertains the beneficiary and indefeasibly vests the interest. For a surviving joint tenant or tenant by the entirety, the state period runs nine months from the other tenant's death. A court with jurisdiction over the property may grant an extension on petition for whatever further period it finds advisable.
Under § 2-801(g), a compliant disclaimer becomes effective according to its terms and irrevocable when both execution and filing are complete. Federal tax qualification is separate: 26 U.S.C. § 2518(b) measures its own nine-month receipt period from the later of transfer or age 21 and adds federal acceptance and destination conditions.
Delivery, filing, and recipient
The original—or an attested copy if more than one court requires filing—goes to the probate court or courts, if any, where the fiduciary controlling the property must file periodic accounts. A copy must also be served by hand or certified mail to the last known address of each person or entity holding or possessing the property. Subsection (e) expressly says a service failure does not affect the disclaimer's validity.
Real-property recording and notice
A real-property disclaimer must use deed-style acknowledgment. To make it valid against people beyond the beneficiary, the beneficiary's heirs and devisees, and persons or entities with actual notice, the original or an attested copy must be recorded in the registry of deeds for the county or district where the land lies. Registered land instead uses the assistant recorder for the registry district.
Acceptance, transfer, insolvency, and creditor bars
Section 2-801(h) (§ 2-801(h)) bars the affected interest after assignment, conveyance, encumbrance, pledge, transfer, another disposition or contract, judicial disposition, insolvency at the attempted disclaimer, a signed written waiver, or acceptance. A beneficiary who knows about the interest and receives a benefit without objection is deemed to have accepted it. For the insolvency bar, the statute applies specified fraudulent-transfer provisions as if the disclaimer were a conveyance.
Effective date and destination
A valid disclaimer is effective according to its terms. A disclaimed power to appoint, consume, apply, or expend is extinguished. Other interests generally pass as if the beneficiary died immediately before the event that finally ascertained the beneficiary and indefeasibly vested the interest, unless that result would substantially impair the governing instrument, statute, or rule of law. The interest never vests in the beneficiary.
What trips people up
The state and federal nine-month clocks are different. Massachusetts uses final ascertainment and indefeasible vesting, and allows a court extension. Federal § 2518 uses transfer or age 21 and does not import the state extension.
Court filing and custodian service have different consequences. Execution plus filing creates effectiveness and irrevocability; failure to serve the custodian does not invalidate the disclaimer, even though the statute still directs that service be made.
Real-property recording is about more than the immediate parties. Without the required acknowledgment and registry step, the disclaimer is not valid against outsiders who lack actual notice, even though the statute preserves it against the beneficiary and the beneficiary's heirs and devisees.
A bar can attach to only part of an interest. Accepting or transferring one part does not automatically eliminate the statutory ability to disclaim another part.
Common questions
Can a surviving joint owner disclaim the share attributable to that owner's own contribution? No. Subsection (b) excludes the portion allocable to amounts the surviving joint tenant or tenant by the entirety contributed.
Does a spendthrift clause prevent a disclaimer? No. Subsection (i) preserves the right despite an express or implied spendthrift provision or similar restraint on alienation.
What if the custodian distributed the property before receiving the disclaimer? Subsection (f) protects a distribution made before delivery of a copy and also protects a good-faith distribution made in reliance on a form-compliant disclaimer when the custodian received the required copy.
