When a family member passes away without a will in Massachusetts, transferring their property to the rightful heirs can feel overwhelming. One of the first steps is filing an affidavit of heirship and the single biggest reason these filings get delayed or rejected is missing or incorrect paperwork. Knowing exactly which documents you need ahead of time saves weeks of frustration and helps you avoid costly mistakes with the probate court.

What Is an Affidavit of Heirship and When Do You Need One?

An affidavit of heirship is a sworn legal statement that identifies the surviving heirs of someone who died without a will (known as dying intestate). In Massachusetts, this document is typically used to establish who has the legal right to inherit real estate, bank accounts, or other assets. It's most common when the deceased owned property and there was no probate administration opened. You can learn more about the specific requirements for intestate succession in Massachusetts to understand when this path applies to your situation.

What Specific Documents Do You Need to Prepare an Affidavit of Heirship in Massachusetts?

Massachusetts probate courts expect a clear paper trail. Here are the core documents you'll need to gather:

1. Certified Death Certificate

You need a certified copy not a photocopy of the decedent's death certificate. This proves the person has passed and establishes the date of death. You can request certified copies from the Massachusetts Registry of Vital Records or the city or town clerk where the death occurred.

2. The Deceased Person's Property Records

If the affidavit involves real estate, you need a copy of the deed showing the decedent's ownership interest. For bank accounts or financial assets, gather account statements or letters from the financial institution. The goal is to show what property is part of the estate.

3. Proof of Family Relationships

This is where many people run into trouble. You must document how each heir is related to the decedent. Supporting records include:

  • Marriage certificates to show a surviving spouse
  • Birth certificates to prove parent-child relationships
  • Divorce decrees if a prior marriage needs to be ruled out
  • Death certificates of other heirs to show when someone who would have inherited has already passed
  • Adoption records if applicable

4. Sworn Statements from Disinterested Witnesses

Massachusetts courts typically require one or two witnesses who are not heirs to sign the affidavit confirming the decedent's family history. These witnesses should have personal knowledge of the family a longtime family friend, neighbor, or someone who knew the decedent for many years. They'll need to swear that the information about the heirs is true and accurate.

5. The Affidavit Itself (Properly Drafted)

The actual affidavit must include the decedent's full legal name, date and place of death, a complete list of all heirs and their relationship to the decedent, a description of the property, and a statement that the decedent died without a will. This document must be signed under oath and notarized. For details on the notarization process, review our guide on notarization requirements for Massachusetts probate court.

6. Identification of the Affiant

The person signing the affidavit (the affiant) must provide valid government-issued identification. Some courts may also request proof that the affiant is one of the identified heirs or has direct knowledge of the family.

Do You Need These Documents If You're Filing Without Full Probate?

Yes in fact, when you're avoiding full probate, the documentation matters even more. Courts and title companies rely heavily on the paperwork because there's no other proceeding to verify the heirs. Our article on filing an affidavit of heirship without probate walks through how this works in practice and what extra steps may apply.

What Common Mistakes Cause Affidavits to Get Rejected?

The most frequent problems are avoidable:

  • Using photocopies instead of certified documents. Courts want certified death certificates and recorded deeds, not copies from a home scanner.
  • Missing an heir. If you leave out a sibling, half-sibling, or child even one you're not close with the affidavit can be challenged later. Under Massachusetts intestate succession law, all heirs must be identified.
  • No witness signatures. Without disinterested witnesses, the affidavit lacks the credibility courts expect.
  • Incorrect property descriptions. The legal description on the deed must match what's written in the affidavit. A street address alone usually isn't enough.
  • Skipping notarization. An unsigned or unnotarized affidavit has no legal weight.

Is an Affidavit of Heirship the Same as a Small Estate Affidavit?

No, and confusing the two is a costly error. A small estate affidavit is used when the total estate value is under a certain threshold and allows a quicker transfer of assets through a different legal process. An affidavit of heirship focuses on proving who the heirs are, often for the purpose of clearing title to real property. If you're unsure which one fits your situation, our comparison of affidavit of heirship versus small estate affidavit documentation breaks down the differences clearly.
