What Documents Are Needed for Will Validation in Massachusetts

If you’re handling a loved one’s estate in Massachusetts, figuring out what paperwork the probate court needs to accept their will can feel overwhelming. Getting it right matters because without the correct documents, the process stalls sometimes for months and that delays everything from paying bills to distributing assets.

What exactly is will validation in Massachusetts?

Will validation is the legal step where the probate court reviews a will to confirm it’s real, properly signed, and not revoked. It doesn’t mean arguing over who gets what that comes later. This stage is about proving the document itself meets state law. You’ll need to file specific forms and supporting evidence before a judge will officially accept it.

Which documents are required to start the process?

The core items you’ll need include:

The original signed will Photocopies usually won’t cut it unless there’s a very good reason the original is missing.
A certified death certificate One issued by the city or town clerk, not just a funeral home copy.
Petition for Probate of Will Form MPC 150, which names the executor and lists heirs.
Affidavit of Execution (if available) Signed by witnesses at the time the will was made, confirming they saw the testator sign it.
List of interested parties Names and addresses of everyone named in the will, plus anyone who would inherit if there were no will (like children or a spouse).

What if the will wasn’t witnessed properly?

Massachusetts requires two witnesses to be present when the will is signed. If that didn’t happen, the court might still accept it under “harmless error” rules but you’ll need stronger proof, like testimony or an affidavit explaining the circumstances.

Do I need a lawyer to submit these documents?

No, but it helps especially if the will is old, unclear, or if family members might object. Mistakes like forgetting to notify an heir or misfiling a form can cause big delays. If you’re doing it yourself, double-check every name, date, and signature. You can read about what the submission process looks like step by step.

Common mistakes people make

Filing a copy instead of the original will courts almost always reject this unless you prove the original was lost or destroyed without intent to revoke.
Missing deadlines You generally have 3 years from the date of death to file, but waiting too long can complicate things.
Not notifying all heirs Even if someone is left out of the will, they still have a right to know the process is happening.
Assuming handwritten wills are valid In Massachusetts, “holographic” wills (handwritten and unwitnessed) are not recognized unless they meet very narrow exceptions.

What happens after I submit everything?

The court schedules a hearing. If no one objects and your paperwork is complete, the judge signs an order accepting the will. That’s when the executor gets formal authority to act. If there’s a dispute or missing info, the court may ask for more evidence or delay approval. You can find out what to expect during the hearing phase here.

When should you talk to a probate attorney?

If any of these apply, get help early:

The will is damaged, unsigned, or missing pages.
Someone is likely to challenge its validity.
You’re unsure who qualifies as an heir under state law.
The deceased owned property in another state that may require separate proceedings.

Even a short consultation can prevent costly errors. For details on what judges look for, check the specific criteria used in court decisions.
