How to File for Guardianship in Massachusetts: Step-by-Step Probate Court Process

Filing for adult guardianship in Massachusetts happens through the Probate and Family Court, and the process is more structured than most parents expect. You are not asking a judge to make you your child's parent again — you are asking the court to strip specific legal rights from an adult and transfer them to you. The court takes that seriously, which is why the clinical evidence requirements, notice rules, and hearing procedures are so rigid.

Here is the full sequence, from assembling the clinical evidence through the final decree.

Step 1: Determine the Right Clinical Form

Massachusetts requires different clinical evidence depending on the nature of the disability. Get this wrong and the petition gets rejected before it reaches a judge.

Clinical Team Report (Form MPC 402) — required when the proposed ward's incapacity stems from an intellectual disability. Three separate licensed professionals must each personally evaluate the individual and sign the document: a registered physician, a licensed psychologist, and a licensed social worker. All evaluations and signatures are valid for 180 days from the earliest exam date.

Medical Certificate (Form MPC 400) — used for all other conditions (developmental disabilities without intellectual disability, traumatic brain injury, psychiatric conditions, degenerative neurological disorders). A single qualified clinician completes this form: a licensed physician, psychologist, certified psychiatric nurse clinical specialist, or nurse practitioner. The clinical examination must have occurred within 30 days of the date the court enters the guardianship decree — not 30 days of filing, but 30 days of the final order.

That 30-day window on the MPC 400 is the single most common timing failure in Massachusetts guardianship petitions. If the court schedules your hearing 45 days out and your Medical Certificate was completed on filing day, it will expire before the decree. Schedule the clinical exam strategically, accounting for your division's typical processing time.

Step 2: Prepare the Filing Package

The standard guardianship petition package includes:

• Form MPC 120 (Petition for Appointment of Guardian of an Incapacitated Person)
• Form MPC 801 (Proposed Fiduciary Bond) — even if bond is waived, the form must be submitted
• Form CJP 34 (CARI/WMS Release Request) — authorizes the court to check the proposed guardian's criminal and DCF history
• Certified copy of the proposed ward's birth certificate
• The applicable clinical form (MPC 400 or MPC 402)

If you are also seeking conservatorship (authority over financial matters), you need a separate Form MPC 130 filed concurrently.

Step 3: File in the Correct Division

Massachusetts operates 14 Probate and Family Court divisions organized by county. You file in the division where the proposed ward permanently resides — not where you live, and not where the proposed ward was born.

Filing fee for guardianship (MPC 120): $0. There is no filing fee for a guardianship petition in Massachusetts. Conservatorship petitions (MPC 130) carry a $240 filing fee plus a $15 surcharge, totaling $255.

After filing, the court issues a Citation — a formal notice document that you must serve on all interested parties. The citation issuance fee is $15.

Step 4: Serve Notice

The court's citation must be served on the proposed ward, their spouse (if any), their parents, and any other interested persons listed in the petition. Service rules require personal delivery or mailing by the deadlines specified on the citation.

Some divisions also require publication of the citation in a local newspaper. Publication costs vary by paper, typically $150 to $200. If the family qualifies as indigent, the court can waive eligible court costs and state-funded publication costs through an Affidavit of Indigency (Form SJC-120).

Step 5: Attend the Hearing

Under Standing Order 1-26 (effective June 1, 2026), routine uncontested fiduciary reviews are presumptively held remotely via Zoom. Contested hearings and evidentiary proceedings are presumptively held in person.

At the hearing, the judge reviews the clinical evidence, asks the petitioner about the proposed ward's functional limitations, and confirms that less restrictive alternatives have been considered. Massachusetts courts are legally required to grant only those powers that are actually necessary — the default is limited guardianship, not plenary (full) control.

If nobody contests the petition and the clinical documentation is in order, many uncontested hearings conclude in 15 to 30 minutes.

Step 6: Receive the Decree and Letters of Appointment

Once the judge signs the decree, you can obtain Certified Letters of Appointment from the court clerk. These letters are what banks, hospitals, schools, and government agencies require as proof of your authority. Each certified copy costs $25.

Order several copies — most institutions want to keep one on file, and you will need separate copies for the hospital system, the school district, SSA, and the DDS service coordinator.

Common Filing Mistakes

• Mixing up MPC 400 and MPC 402. Using the wrong form for the diagnosis type delays the entire proceeding.
• Filing in the wrong county. If the proposed ward recently moved, confirm their current legal residence before filing.
• Missing the 30-day clinical window. For MPC 400 cases, the exam date must fall within 30 days of the decree, not the filing date.
• Forgetting the bond form. Even when bond is likely to be waived, Form MPC 801 must be submitted with the initial package.
• Not requesting Rogers authority upfront. If antipsychotic medication is part of the ward's treatment plan, failing to request Rogers authority during the initial petition means filing a separate motion later.

Processing Times by Division

Larger urban divisions (Middlesex, Suffolk) can take several weeks between filing and citation issuance, and hearing schedules vary by division. Smaller divisions (Barnstable, Norfolk) often process more quickly and may offer access to "Lawyer for the Day" volunteer programs for families filing without an attorney.
