Adult Guardianship and Conservatorship Petition Requirements in Massachusetts
At a glance
| Proceeding and state terminology | Massachusetts Uniform Probate Code, G.L. c. 190B, Art. V. Two distinct tracks: a guardian of an 'incapacitated person' handles personal care, health, and welfare (Part 3, §§ 5-301 to 5-312); a conservator or other protective order handles property and business affairs (Part 4, §§ 5-401 to 5-431). Both are filed in the Probate and Family Court and may be sought together but are separate legal determinations; 'ward' is reserved for minors (§ 5-101(6),(25)). |
|---|---|
| Who may file and where | Guardianship: the incapacitated person or any person interested in their welfare (§ 5-303(a)). Conservatorship: the person to be protected or anyone interested in their estate, affairs, or welfare — including a parent, guardian, custodian, or anyone adversely affected by unmanaged property (§ 5-404(a)). File in the Probate and Family Court (§ 5-101(3)); the code's guardianship/conservatorship venue sections are reserved, so § 1-303 gives the first-commenced division the exclusive right to proceed and governs transfer. |
| What the petition must contain | Guardianship (§ 5-303(b)): petitioner's identity and interest; the adult's name, age, residence and proposed residence; nature of the alleged incapacity and whether intellectual disability, substituted-judgment treatment authority, or nursing-facility admission is sought; proposed guardian and priority basis; spouse, children/parents/siblings/heirs; care or custody person; any existing power of attorney or health care proxy; why guardianship (and why not a limited one) is needed; a property statement with value; and a statement that a medical certificate (or clinical team report) is filed or an affidavit of why it cannot be. Conservatorship (§ 5-404(b),(c)): the same core facts plus best-interest reason, proposed conservator, and a § 5-303(c)-conforming certificate. |
| Proof required for appointment | Guardianship: the adult must be an 'incapacitated person' — for reasons other than advanced age or minority, a clinically diagnosed condition causing inability to receive and evaluate information or make or communicate decisions to the extent the person cannot meet essential requirements for physical health, safety, or self-care, even with appropriate technological assistance (§ 5-101(9)); the court must also find appointment necessary or desirable and that needs cannot be met by less restrictive means (§ 5-306(b)). Conservatorship: inability to manage property effectively from a clinically diagnosed impairment (or detention/inability to return to the U.S.) plus property that will be wasted or funds needed (§ 5-401(c)). The statute lists required findings but sets no quantified burden in the appointment sections; a conservatorship is expressly not a determination of incapacity (§ 5-407(f)). |
| Alternatives the court must address | Mandatory limit, not just a consideration. The court may appoint a guardian or conservator only if it finds the person's needs 'cannot be met by less restrictive means, including use of appropriate technological assistance' (§§ 5-306(b)(8), 5-407(b)(8)), and must make orders 'only to the extent necessitated' by the person's limitations while encouraging maximum self-reliance (§§ 5-306(a), 5-407(a)). The guardianship petition must say why a limited guardianship is inappropriate (§ 5-303(b)(10)) and disclose any existing power of attorney or health care proxy (§ 5-303(b)(9)). The statute frames alternatives as limited orders, technological supports, and existing agents rather than naming supported decision-making. |
| Notice, service, and hearing timing | The petitioner must give notice to the respondent (if 14 or older) and the spouse and children, or else parents and siblings, or else heirs; any serving guardian/conservator or care-or-custody person; the nearest adult relative if no one else is notified; everyone named in the petition; the Department of Developmental Services if intellectual disability is alleged; and the U.S. Veterans Administration if benefits are involved (§ 5-304(a)). Notice must be served personally on the respondent, and the respondent may not waive notice (§ 5-304(c),(d)). The code fixes personal service and other recipients but sets the manner through § 1-401 and court order rather than one general day-count; the emergency track requires 7 days' notice (§ 5-308(c)). |
| Counsel and hearing rights | On request by the adult or someone on their behalf, or whenever the court finds the adult's interests are or may be inadequately represented, the court shall appoint an attorney, giving weight to the adult's choice if 14 or older; indigent counsel is paid by the commonwealth or petitioner, and the right to retain chosen counsel is preserved (§ 5-106(a)). The adult is entitled to be present in person at any hearing, to be represented by counsel, to present evidence, and to cross-examine witnesses including any physician or guardian ad litem, and may request a closed hearing (§ 5-106(c)). No statutory jury trial is provided for these petitions. |
| Medical evidence or court evaluator | Medical-certificate model, not a universal court investigator. A guardianship petition must be accompanied by (or the court must already hold) a medical certificate based on an examination within 30 days of filing, signed by a registered physician, certified psychiatric nurse clinical specialist, nurse practitioner, or licensed psychologist and describing the nature, type, and extent of the person's cognitive and functional limitations, mental and physical condition, prognosis, and exam date (§§ 5-303(b)(11), 5-303(c)); intellectual disability instead requires a physician/psychologist/social-worker clinical team report within 180 days (§ 5-303(d)). The court may waive or postpone the certificate only on a supported affidavit that it cannot be obtained, may order further examination and appoint experts (§ 5-303(e)), and may name a guardian ad litem to investigate (§ 5-106(b)). Conservatorship requires a § 5-303(c)-conforming certificate within 30 days (§ 5-404(b)(11)). |
| Limits on the order | Before appointing, the court must find a qualified person, proper venue, notice given, a current medical certificate (exam within 30 days of the hearing), status as an incapacitated or disabled person, that appointment is necessary or desirable, and that needs cannot be met by less restrictive means (§§ 5-306(b), 5-407(b)); it may limit powers to create a limited guardianship endorsed on the letters (§ 5-306(c)). A guardian cannot consent to substituted-judgment treatment such as antipsychotic medication without a specific court order after a counseled hearing (§ 5-306A) or admit the adult to a nursing facility without a specific best-interest finding (§ 5-309(g)). Emergency relief is a separate track: a temporary guardian for up to 90 days on a finding of likely immediate and substantial harm (§ 5-308), which is not a final determination of incapacity. |
Requirements one by one
Proceeding and state terminology
Massachusetts uses the Massachusetts Uniform Probate Code (MUPC), G.L. c. 190B, Article V, and splits the case into two legally distinct tracks handled by the Probate and Family Court:
- A guardianship covers personal decisions — support, care, health, and welfare — for an adult who is an "incapacitated person" (Part 3, §§ 5-301 to 5-312).
- A conservatorship (or another "protective order") covers property and business affairs for a "disabled" adult (Part 4, §§ 5-401 to 5-431).
The two can be requested for the same person, but they answer different legal questions and require separate findings. Massachusetts uses "guardian" for an adult incapacitated person; the term "ward" is reserved for a person under guardianship "solely because of minority" (§ 5-101(6), (25)).
Who may file and where
For a guardianship, "an incapacitated person or any person interested in the welfare of the person alleged to be incapacitated" may petition (§ 5-303(a)). For a conservatorship, the class is broader: the person to be protected or anyone interested in that person's "estate, affairs, or welfare," including a parent, guardian, custodian, or anyone "who would be adversely affected by lack of effective management" of the property (§ 5-404(a)).
The petition is filed in the Probate and Family Court (§ 5-101(3)). The MUPC's guardianship and conservatorship venue sections (§§ 5-302 and 5-403) are Reserved, so there is no single county-of-residence sentence to quote; the general rule in § 1-303 controls when a case could be brought in more than one division — the division where it is filed first "has the exclusive right to proceed," and a court may transfer a file in the interest of justice.
What the petition must contain
Section 5-303(b) sets out a long guardianship checklist: the petitioner's name, residence, relationship, and interest; the adult's name, age, and residence; the proposed residence if appointment is made; the nature of the alleged incapacity, and whether intellectual disability, authority to consent to substituted-judgment treatment, or nursing-facility admission is sought; the proposed guardian and any priority claim; the family tree (spouse and children, or parents and siblings, or heirs); the person who has care or custody of the adult; any existing power of attorney or health care proxy; why a guardianship is necessary and why a limited one is inappropriate; a property statement with an estimated value; and the medical-certificate statement described below.
A conservatorship petition under § 5-404 tracks the same core facts and adds the best-interest reason for appointment, the proposed conservator, the type of conservatorship (and, if general, why a limited one will not work), and a medical certificate conforming to § 5-303(c).
Proof required for appointment
The two tracks use different functional tests. For a guardianship, the adult must be an "incapacitated person" under § 5-101(9): for reasons other than advanced age or minority, a clinically diagnosed condition that leaves the person unable to receive and evaluate information or make or communicate decisions "to such an extent that the individual lacks the ability to meet essential requirements for physical health, safety, or self-care, even with appropriate technological assistance." The court must also find that appointment is "necessary or desirable" and that the person's needs "cannot be met by less restrictive means" (§ 5-306(b)).
For a conservatorship, § 5-401(c) requires that the adult be unable to manage property and business affairs effectively because of a clinically diagnosed impairment (or because the person is detained or unable to return to the United States), and that property will be wasted or dissipated or money is needed for support. A conservatorship is expressly "not a determination of incapacity of the protected person" (§ 5-407(f)).
The statute lists the findings the court must make but does not attach a quantified burden of proof (such as "clear and convincing") in the appointment sections themselves.
Alternatives the court must address
Less restrictive means is a hard limit, not a suggestion. The court "may appoint" only if it finds the person's needs "cannot be met by less restrictive means, including use of appropriate technological assistance" (§§ 5-306(b)(8), 5-407(b)(8)), and it must exercise its authority "to encourage the development of maximum self-reliance and independence" and make orders "only to the extent necessitated" by the person's limitations (§§ 5-306(a), 5-407(a)). The guardianship petition itself must state "the reason why limited guardianship is inappropriate" (§ 5-303(b)(10)) and disclose any existing power of attorney or health care proxy (§ 5-303(b)(9)). Massachusetts frames alternatives as limited orders, technological supports, and existing agents rather than by naming supported decision-making agreements.
Notice, service, and hearing timing
Section 5-304(a) requires the petitioner to notify a defined circle: the respondent (if 14 or older) and the spouse and children, or else parents and siblings, or else heirs; anyone serving as guardian or conservator or who has had care or custody of the person; the nearest adult relative if no one else is reached; everyone named in the petition; the Department of Developmental Services if intellectual disability is alleged; and the U.S. Veterans Administration where benefits are involved. Two rules are strict: notice "shall be served personally" on the respondent, and the respondent "may not waive notice" (§ 5-304(c), (d)).
These sections fix who must be served and that service on the adult is personal, but set the manner through § 1-401 and court order rather than a single general day-count. By contrast, the emergency track sets an express 7-day notice period for a temporary guardian (§ 5-308(c)).
Counsel and hearing rights
Counsel is not automatic in every case, but the trigger is broad. Under § 5-106(a), the court "shall appoint an attorney" whenever the adult (or someone on their behalf) requests one, or whenever the court finds "at any time" that the adult's interests "are or may be inadequately represented," giving weight to the adult's own choice if 14 or older. Indigent counsel is paid by the commonwealth or the petitioner, and the adult keeps the right to hire chosen counsel.
Section 5-106(c) guarantees the core hearing rights: the adult "is entitled to be present at any hearing in person," to be represented by counsel, "to present evidence, to cross-examine witnesses, including any physician or other qualified person and any guardian ad litem," and to a closed hearing on request. There is no statutory jury trial for these petitions.
Medical evidence or court evaluator
Massachusetts centers a medical certificate, not a court investigator. A guardianship petition must be accompanied by (or the court must already hold) a certificate based on an examination within 30 days of filing, signed by a registered physician, certified psychiatric nurse clinical specialist, nurse practitioner, or licensed psychologist, describing "the nature, type, and extent of the person's specific cognitive and functional limitations," an evaluation of the person's condition, a prognosis, and the examination date (§ 5-303(b)(11), (c)). An adult alleged to have an intellectual disability is instead examined by a three-member clinical team — a physician, a licensed psychologist, and a social worker — whose report must be dated within 180 days (§ 5-303(d)).
The court may "waive or postpone" the certificate only on a supported affidavit that it is impossible to obtain (§ 5-303(b)(11)(B)), may order further examination and appoint experts (§ 5-303(e)), and may appoint a guardian ad litem to investigate (§ 5-106(b)). A conservatorship petition requires a § 5-303(c)-conforming certificate within 30 days (§ 5-404(b)(11)).
Limits on the order
Before appointing, the court must make the § 5-306(b) (guardian) or § 5-407(b) (conservator) findings: a qualified appointee, proper venue, notice given, a current medical certificate (examination within 30 days of the hearing), incapacitated or disabled status, that appointment is necessary or desirable, and that needs cannot be met by less restrictive means. It "may limit the powers" of a guardian to create a limited guardianship endorsed on the letters (§ 5-306(c)).
Two powers are walled off from an ordinary appointment. A guardian cannot consent to treatment that may require a substituted-judgment determination — such as antipsychotic medication — without a specific court order entered after a hearing at which counsel is provided (§ 5-306A), and cannot admit the adult to a nursing facility without a specific best-interest finding (§ 5-309(g)).
Emergency relief lives in a separate statute. Section 5-308 lets the court name a temporary guardian for up to 90 days on a finding that ordinary procedure "will likely result in immediate and substantial harm," and that appointment "is not a final determination of a person's incapacity." Its shorter notice and interim powers should not be treated as the ordinary standard.
What trips people up
A diagnosis alone is not the test. Section 5-101(9) asks whether a clinically diagnosed condition actually leaves the adult unable to meet essential health, safety, or self-care requirements even with technological help — and it excludes "advanced age" as a stand-alone reason. The court must still find that no less restrictive option works.
Guardianship and conservatorship are separate cases. Personal authority (§ 5-306) and property authority (§ 5-401) rest on different facts and different findings. Winning one does not carry the other, and a conservatorship specifically is "not a determination of incapacity."
The 30-day clock runs to the hearing, not just to filing. The petition needs a certificate examined within 30 days of filing (§ 5-303(b)(11)), and § 5-306(b)(4) requires the examination to have occurred within 30 days before the hearing. A certificate that was fresh at filing can go stale before the hearing and have to be refreshed.
Common questions
Can a guardian put my relative in a nursing home or start antipsychotic medication? Not on the strength of an ordinary appointment. A nursing-facility admission needs a specific best-interest court finding (§ 5-309(g)), and substituted-judgment treatment such as antipsychotic medication needs a separate court order after a counseled hearing (§ 5-306A).
Does the person have to attend the hearing? They have the right to attend in person and to participate through counsel (§ 5-106(c)), and they must be served personally and cannot waive notice (§ 5-304(c), (d)). The statute frames attendance as the adult's right rather than an absolute requirement.
What if there is an immediate crisis before the hearing? The court can appoint a temporary guardian for up to 90 days under § 5-308 on a finding of likely immediate and substantial harm, with 7 days' notice that can be shortened in a true emergency — but that is interim relief and not a final incapacity finding.
