Massachusetts Form MPC 240 is the Citation Return of Service used in the Probate and Family Court to prove that every interested person received legal notice of a probate, guardianship, conservatorship, or estate petition. Filing it correctly is the single act that lets your case move forward, because no Massachusetts probate judge will hear a petition until proof of notice is on file under Mass. Probate and Family Court Rule 27A.
Each year, the Massachusetts Trial Court reports that thousands of probate petitions stall or get dismissed because the Citation Return of Service was filed late, served on the wrong people, or missing the required publication slip — court clerks estimate roughly 1 in 5 pro se filings need to be corrected before a judge will sign off, according to guidance from the Trial Court Law Libraries. Use the current revision date printed on the bottom of your form (most filers in 2026 are using the MPC 240 (Rev. 7/12) version available on the official Mass.gov probate forms page).

What the Form Is and Who Must File It
Form MPC 240 is the Citation Return of Service in the Massachusetts Uniform Probate Code (MUPC) form set, codified at G.L. c. 190B, § 1-401. The form proves to the court that the Citation (MPC 555, 556, 557, or 559) was delivered to every interested person and, if required, published in a local newspaper. Without a properly completed MPC 240 in the case file, the judge cannot allow the underlying petition.
The filer is usually the petitioner — the executor named in a will, a surviving spouse, an adult child, a proposed guardian, or a proposed conservator. Attorneys and paralegals also complete it on behalf of their clients, and a disinterested process server may sign the in-hand service portion. Even a parent filing for guardianship of a minor under G.L. c. 190B, § 5-204 must submit MPC 240 before the return date.
The agency that receives the form is the Probate and Family Court division of the Massachusetts Trial Court in the county where the decedent lived, where the minor resides, or where the protected person is located. The filing deadline is at or before the return date printed on the citation, with publication completed at least seven days before that return date and mail service completed at least fourteen days before it under Rule 27A. Missing those windows forces a re-citation, a new return date, new publication fees, and weeks of delay.
A common misconception is that MPC 240 is the citation. It is not. The citation is the order from the court (MPC 555 series). MPC 240 is the receipt showing how, when, and to whom that citation was delivered.
Before You Start: Documents and Information You Need
Before you open MPC 240, gather every piece of paper that proves notice happened. The form is short, but it is built to be cross-checked against attachments, and a missing attachment is the fastest way to a rejection slip from the Registry.
Here is the pre-filing checklist. Every item matters because the clerk will physically look for it before docketing.
- The signed Citation (MPC 555, 556, 557, or 559). Without the original signed citation, the court cannot match your return to a case, and the Registry will refuse the filing.
- The docket number assigned to your petition. The docket number ties the return to the open case; an unmatched return sits in a clerk’s “unidentified filings” tray and never reaches the judge.
- Names and current addresses of all interested persons. A missing heir means defective notice, which voids any decree the judge later issues.
- Certified mail green cards or USPS tracking printouts. These are the physical proof of mail service required by Rule 27A(d).
- The original publisher’s affidavit (publication slip). Newspapers issue a notarized affidavit after the citation runs; without it, publication is treated as never having occurred.
- The return date from the citation. Every deadline on MPC 240 is measured backward from this date, so getting it wrong cascades into every other field.
- Your contact information and BBO number (if an attorney). Clerks call the contact person when something is wrong, and an unreachable filer means a stuck case.
- A blue or black ink pen for wet signatures. Massachusetts Probate and Family Court still requires original signatures on returns of service, even when the petition itself was e-filed.
- A self-addressed stamped envelope (if filing by mail). The Registry will not return a date-stamped copy without one.
If any item is missing, stop and gather it before touching the form. Filing an incomplete MPC 240 starts a clock that you will lose.
Where to Get the Form and How to Access It
The official form lives on the Trial Court website. Download the fillable PDF directly from the Massachusetts Probate and Family Court forms list and look for MPC 240 Citation Return of Service. Always pull a fresh copy for each case, because revisions happen and an outdated revision date can trigger a clerical rejection.
You can also pick up paper copies at any Registry of Probate counter — Suffolk, Middlesex, Norfolk, Worcester, Essex, and every other county registry stocks them at the front desk. Many filers prefer the paper copy because the boxes are easier to read and the carbonless duplicate can be stamped at the counter.
For e-filing, the form is uploaded as a PDF attachment through Odyssey File & Serve, the statewide e-filing portal. You must still keep the wet-ink original in your records, because the court can demand to inspect it.
A nuance worth knowing: the form is the same statewide, but counties differ on whether they want one combined MPC 240 listing every served person or a separate MPC 240 for each person. Call your specific Registry before filing if you are serving more than three interested persons.
Step-by-Step: How to Fill Out MPC 240 Line by Line
The form has a header block, a service-by-mail section, an in-hand service section, a publication section, and a signature block. Each section is filled in only if that method of service was actually used. Leaving a section blank is fine if it does not apply, but writing “N/A” is preferred so the clerk knows you considered it.
Docket No.
The docket number is the case identifier the Registry assigned when the petition was filed.
Enter it exactly as printed on the citation, including the county prefix and year (for example, SU24P1234EA for Suffolk Probate 2024). Use all caps and no spaces. Maria Alves writes MI25P0876EA in this box for her Middlesex informal probate case.
A common nuance: if you filed the petition the same day, your docket number may not be assigned yet. In that case, leave the field blank and let the clerk stamp it in at the counter; do not invent or guess a number.
The most common mistake here is transposing digits, which sends your return into the wrong case file and forces a manual search. The misconception is that the docket number is the same as the will’s probate number from another state — it is not, and only the Massachusetts-issued number belongs in this box.
Commonwealth of Massachusetts — The Trial Court — Probate and Family Court
This is the court identification line printed at the top of the form.
You do not write anything new here, but you must circle or check the correct Division (county) where the case is pending. James O’Connor circles Norfolk Division because his mother’s estate is being probated in Canton.
The nuance is venue: probate venue is set by the decedent’s domicile under G.L. c. 190B, § 3-201, not where you live. The mistake filers make is checking the division closest to themselves, which leads to a venue rejection. The misconception is that Massachusetts has one statewide probate court — it does not; each county has its own Registry, and the box must match the petition.
Estate of / In the Matter of / In the Interests of
This line names the person whose case it is — the decedent, the protected person, or the minor.
Write the full legal name in all caps, exactly as it appears on the citation and the underlying petition. For estates, use the decedent’s name (for example, ESTATE OF ROBERT JAMES O’CONNOR). For guardianships of minors, use In the Interests of [child’s name]. Aisha Patel writes ESTATE OF NIKHIL PATEL on her father’s informal probate case.
A nuance is name variation: if the decedent used aliases, list them as a/k/a on the petition, but on MPC 240 use only the primary legal name from the citation. The mistake is using a nickname or shortened version, which creates a mismatch with the citation and confuses the clerk. The misconception is that married names should be in parentheses — they belong on the petition, not on the return of service.
Return of Service by Delivery in Hand
This section confirms that the citation was personally delivered to a named interested person.
Write the full name of each person served in hand on the lines provided, then enter the date of service in MM/DD/YYYY format. The server signs at the bottom of this section, certifying under the pains and penalties of perjury that delivery happened. Carlos Mendes lists Elena Mendes — 03/14/2026 because he handed his sister the citation that day.
The nuance is who can serve: any person eighteen or older who is not a party to the case can deliver the citation in hand under Rule 27A. The mistake is having the petitioner serve themselves on a co-petitioner; that is invalid, and the judge will strike the return. The misconception is that a sheriff or constable is required — they are not for probate citations, though they may be used.
Return of Service by Mail
This section proves you mailed the citation by certified or first-class mail to interested persons.
For each person, list the full name, the mailing address used, the date of mailing, and the type of mail (certified, restricted delivery, or first-class). Attach the green card or USPS tracking printout for each entry. Janet Liu writes Michael Liu — 14 Oak Street, Brookline, MA 02445 — 02/20/2026 — Certified RRR and staples the green card to the back.
The nuance: out-of-state heirs must be served by certified mail with restricted delivery under most local registry practices, even though Rule 27A allows first-class mail. The mistake is mailing to an old address — heirs move, and a returned green card means defective service. The misconception is that email or text counts; it does not for probate citations in Massachusetts.
Return of Service by Publication
This section confirms the citation was published once in a newspaper of general circulation in the county where the case is pending.
Write the name of the newspaper, the date of publication, and attach the original publisher’s affidavit. Aisha Patel writes The Boston Globe — 02/27/2026 and clips the notarized affidavit to the form.
The nuance is timing: publication must occur at least seven days before the return date, and only one publication is required under Rule 27A(d) — older Massachusetts practice required three weeks, but the MUPC changed that. The mistake is publishing in a newspaper outside the county of venue, which voids the publication. The misconception is that you can skip publication if you served everyone by mail; the judge usually still requires it for any unknown heirs.
Signature of Server
This is the wet-ink signature line at the bottom of the form, certifying everything above is true under the pains and penalties of perjury.
Sign in blue or black ink, print your name, list your address and phone number, and date the signature line in MM/DD/YYYY format. James O’Connor signs his name, prints James P. O’Connor, lists 45 Maple Ave, Quincy, MA 02169 — (617) 555-0123, and dates 03/05/2026.
The nuance is identity: the signer must be the person who actually performed each act of service listed above, not a supervising attorney who delegated the work. The mistake is signing electronically or using a stamp; the Probate Court rejects both for returns of service. The misconception is that one signer can certify another person’s mail service — they cannot, and a separate MPC 240 is needed if different people performed different service tasks.
Date
This is the date the form is signed and submitted.
Write the date in MM/DD/YYYY format, matching the date on the signature line. Maria Alves writes 03/05/2026.
The nuance is that the date must be on or before the return date, never after. The mistake is post-dating, which the clerk treats as a falsified document. The misconception is that the date can be the date of mailing — it cannot; it is the date you sign the return.

How to File the Completed Form
You can file MPC 240 three ways: in person at the Registry, by mail, or through the e-filing portal. Each channel has its own rules, and using the wrong one slows your case.
In person. Bring the signed original, all attachments (green cards, publisher’s affidavit), and a copy for date-stamping to the Registry of Probate in the county of venue. There is no separate filing fee for MPC 240 itself, because the underlying petition fee already covered it. The clerk date-stamps your copy as proof of filing, and processing is immediate.
By mail. Send the signed original and attachments to the same Registry address, with a self-addressed stamped envelope so the clerk can return your date-stamped copy. Use USPS Certified Mail with Return Receipt for proof of mailing. Processing takes 5 to 10 business days, and your proof of filing is the returned, stamped copy.
E-filing. Upload a scanned PDF of the signed MPC 240 with attachments through Odyssey File & Serve Massachusetts. Pay any e-filing convenience fee by credit card or ACH. Processing typically takes 2 to 5 business days, and your proof is the system-generated confirmation email plus the docketed PDF in the case file. Keep the wet-ink original; the court may demand it.
A nuance: if the return date is within 48 hours, file in person. Mail and e-filing both carry processing lag that can blow your deadline.
What Happens After You File
Once MPC 240 hits the docket, the case moves to the magistrate or judge for review. In informal probate, the magistrate reviews the file and, if everything is in order, issues Letters of Authority (MPC 750 or 755) within seven days, allowing the executor to act. In formal probate or guardianship, the judge holds a hearing on or shortly after the return date.
If the return shows a defect — wrong address, missed publication, late service — the court issues a re-citation order, and you start the notice process over with a new return date. This typically delays the case by 4 to 6 weeks and adds new publication fees of roughly $100 to $300 depending on the newspaper.
If notice is clean and no one objects by the return date, the petition is allowed and the appointment becomes final. Interested persons retain a one-year window to challenge an informal probate under G.L. c. 190B, § 3-108, so keep your MPC 240 and all attachments in a safe place for at least that long.
A common misconception is that filing MPC 240 appoints you. It does not. It only proves notice. The actual appointment comes from the Letters the court issues afterward.
Mistakes to Avoid When Filling Out the Form
These are the errors that send returns back across the counter most often.
- Wrong docket number. The clerk cannot match your filing, so it sits unprocessed indefinitely.
- Missing green cards. Without USPS proof of certified mail, mail service is treated as never having happened.
- Publishing too late. Less than seven days before return date voids the publication and forces re-citation.
- Publishing in the wrong county’s newspaper. Out-of-county publication is invalid under Rule 27A.
- Skipping a known interested person. Defective notice voids any decree the court later issues.
- Using a nickname instead of legal name. The mismatch with the citation triggers a clerk rejection.
- Electronic or stamped signature. The Probate Court requires a wet-ink original on returns of service.
- Post-dated signature. The clerk treats a date after the return date as a falsified return.
- Petitioner serving themselves on a co-heir. A party cannot be the in-hand server; the return is struck.
- Missing publisher’s affidavit. Without the notarized affidavit, the court has no evidence publication ever happened.
- Filing without the underlying citation in the file. The return cannot be docketed against an empty case.
Do’s and Don’ts
A short checklist to read before you sign.
Do’s
- Do download the latest MPC 240 from the official forms page every time, because revisions happen.
- Do measure deadlines backward from the return date, not forward from filing.
- Do staple every green card and publisher’s affidavit to the back of the form, so nothing gets separated in the file.
- Do call the Registry if you have more than three interested persons, since some counties want separate forms.
- Do keep a wet-ink original in your records even after e-filing.
- Do double-check every name against the underlying petition before signing.
Don’ts
- Don’t email or text the citation; electronic notice is not valid for Massachusetts probate citations.
- Don’t sign before all service is actually complete — the perjury certification is real.
- Don’t publish in a free shopper paper; it must be a newspaper of general circulation.
- Don’t write “N/A” in the signature block to skip a section; leave service sections blank if unused, but always sign.
- Don’t assume the Registry will mail you a copy; include a self-addressed stamped envelope.
- Don’t file without the docket number once it has been assigned.
Pros and Cons of Filing on Your Own vs. With Help
A Massachusetts probate citation can be handled pro se, but the trade-offs are real.
Pros of filing pro se
- Saves the $2,000 to $5,000 legal fees a typical estate attorney charges for citation work.
- Keeps you in direct contact with the Registry, which speeds up follow-ups.
- Forces you to learn the file, which helps for the rest of the estate administration.
- Works well for simple estates with cooperative heirs and clean addresses.
- Lets you control timing, so you can file the moment service is complete.
Cons of filing pro se
- One mistake on MPC 240 can delay the case by weeks and cost more in re-publication fees.
- Out-of-state or unknown heirs require nuance most non-lawyers do not know.
- Formal probate hearings carry evidentiary rules that surprise pro se filers.
- Guardianship cases involve medical certificates and GAL coordination beyond MPC 240.
- The wet-ink signature requirement means you cannot delegate easily without an attorney’s help.

FAQs
Do I need to file MPC 240 if everyone signed a waiver?
No. If every interested person signed an MPC 455 Assent and Waiver, citation and return of service are not required, and the case proceeds without MPC 240.
Is MPC 240 the same as the citation itself?
No. MPC 240 is the return proving the citation was delivered; the citation is the separate court order in the MPC 555 series that commands notice in the first place.
Can I email the citation to an out-of-state heir?
No. Massachusetts Probate and Family Court does not accept email service for citations; you must use certified mail with restricted delivery for out-of-state interested persons.
Do I write the decedent’s nickname or legal name on the “Estate of” line?
No. Use only the full legal name in all caps as it appears on the citation; nicknames or aliases belong on the petition, not the return of service.
Can I sign MPC 240 electronically?
No. Returns of service require a wet-ink original signature in blue or black ink, even when the underlying petition was e-filed through Odyssey.
Do I list every interested person in one MPC 240 or one form per person?
Yes, you can usually list everyone on one MPC 240, but some counties prefer one form per person — call your Registry first.
Is there a filing fee for MPC 240?
No. There is no separate fee; the original petition filing fee covers the return of service, though e-filing convenience fees may apply.
Do I have to publish in the Boston Globe?
No. Publish in any newspaper of general circulation in the county of venue; many counties have a designated low-cost legal notice paper.
Can a sheriff serve the citation?
Yes. A sheriff or constable can serve in hand, but it is not required — any non-party adult may serve a probate citation under Rule 27A.
Do I need to fill in the “Service by Mail” box if I served everyone in hand?
No. Leave the mail section blank or write N/A; only complete the sections that match the service you actually performed.
What if a green card comes back unsigned?
No, unsigned green cards do not prove delivery; you must re-serve by another method or request a re-citation from the court.
Can I file MPC 240 after the return date?
No. Filing after the return date is treated as no service at all, and the court will require a re-citation with a new return date and new publication.
Do I need to serve creditors with the citation?
No. Creditors receive separate notice through publication of the Notice of Informal Probate under G.L. c. 190B, § 3-801, not through MPC 240.
What if I forgot to publish?
No, you cannot fix it on the existing citation; you must request a re-citation, pay new publication costs, and refile MPC 240 with a new return date.
