Massachusetts Probate Inventory Form MPC 854 and Probate Accounting: A Practical Guide

Once a Personal Representative is appointed in a Massachusetts probate proceeding, one of the first substantive obligations is inventorying the estate. This is not optional, even in unsupervised administrations. The inventory establishes the baseline for tax calculations, creditor claims, and ultimate distribution to heirs — and getting the valuation wrong at this stage creates problems that compound throughout the entire administration.

What MPC 854 Is and Who Must Complete It

Form MPC 854 (Inventory) is the official Massachusetts Probate and Family Court document used by the Personal Representative to catalog and value all probate assets belonging to the decedent at the time of death.

"Probate assets" are assets owned solely by the decedent, with no named beneficiary or survivorship designation. This typically includes:

• Real estate titled solely in the decedent's name
• Solely owned bank and investment accounts without a payable-on-death designation
• Personal property (vehicles, jewelry, household goods, collectibles)
• Business interests
• Money owed to the decedent (accounts receivable, outstanding loans)

Assets that pass outside of probate — life insurance with a named beneficiary, jointly held accounts with right of survivorship, IRAs and 401(k)s with beneficiary designations, assets in a living trust — are not listed on MPC 854.

The form itself asks the Personal Representative to list each asset with a description, the estimated fair market value at the date of death, and the date of the valuation. For real estate, a formal appraisal by a licensed Massachusetts appraiser is standard practice, both because it establishes defensible value for tax purposes and because creditors or heirs can challenge an unrealistically low valuation.

When Does the Inventory Have to Be Filed?

Under the Massachusetts Uniform Probate Code, the requirement depends on whether the administration is supervised or unsupervised.

Unsupervised (Informal) Probate: The Personal Representative is not required to file the MPC 854 with the court. However, they are legally required to provide a copy of the inventory to all interested persons — meaning all heirs, beneficiaries, devisees, and any known creditors — within three months of appointment. Failure to do so exposes the Personal Representative to removal or surcharge by the court.

Supervised (Formal) Probate: The inventory must be filed with the court, and interested persons may challenge valuations through the formal judicial process.

In practice, even in informal probate proceedings, many Personal Representatives file the inventory with the court voluntarily to create a clear record and protect themselves from future disputes about what was in the estate.

Massachusetts Probate Accounting: Form MPC 857

A formal accounting is a financial report filed with the Probate and Family Court that details all receipts into the estate (assets collected), disbursements made from the estate (expenses paid and bills settled), and the remaining balance proposed for distribution to heirs.

Accountings are required in supervised (formal) probate. In unsupervised proceedings, the Personal Representative can skip the formal court accounting if all interested persons consent to the distribution in writing. When heirs are cooperative and the estate is straightforward, this signed consent route is common and avoids the accounting filing fee.

When a formal accounting is filed using Form MPC 857, the court charges a filing fee based on the gross estate value reported in Schedule A of the accounting:

These fees are paid from the estate, not from the Personal Representative personally.

Registry of Deeds Recording Fees: What to Expect

Several documents generated during Massachusetts estate administration must be recorded at the County Registry of Deeds, and each recording carries a fee. The most common recording events during estate administration are:

Affidavit of No Estate Tax Due: For estates with a gross value under $2 million, the Personal Representative clears the automatic Massachusetts estate tax lien from real property by recording this affidavit at the appropriate Registry of Deeds. The standard recording fee is $105 (which includes the Community Preservation Act surcharge where applicable). This fee varies slightly by county and can be confirmed with the specific Registry before filing.

Deed conveying real estate from the estate: When real property is transferred from the estate to a beneficiary or sold to a third party, the deed must be recorded. Recording fees are typically $155 for a standard deed, again including CPA surcharges where the municipality has adopted the CPA.

Declaration of Homestead: If the surviving spouse records a new Declaration of Homestead after the death (to independently establish the $1,000,000 equity protection), the recording fee is the same standard document fee — approximately $105 to $155 depending on the county and document length.

Mortgage discharges and lien releases: When the estate pays off a mortgage or other secured lien, recording the discharge also carries a fee, typically in the $75 to $105 range.

Registry of Deeds fees are set by the state legislature and indexed to document type rather than property value. The specific Registry serving the county where the real property is located handles the recording. Massachusetts has 21 Registries of Deeds, organized by county (and in some cases sub-county). Confirm current fees directly with the relevant Registry before filing, as CPA surcharge rates vary by municipality.

One Critical Tax Interaction: The Inventory Value and the $2 Million Threshold

The value established on the MPC 854 inventory directly affects whether the estate must file Form M-706 (the Massachusetts Estate Tax Return). For deaths on or after January 1, 2023, an estate tax return is required only if the gross estate plus adjusted taxable gifts exceeds $2 million.

The gross estate for Massachusetts estate tax purposes is broader than just the probate inventory. It includes:

• All probate assets (what goes on MPC 854)
• Life insurance payable to the estate or taxable under IRC § 2042
• Certain jointly held property
• Retained interests in trusts
• Adjusted taxable gifts made during the decedent's lifetime

This means an estate where the MPC 854 inventory shows $1.5 million could still exceed $2 million for tax purposes once life insurance and joint assets are added in. Conversely, a large-looking probate estate may not trigger a filing requirement if most of the wealth passed through non-probate channels.

The nine-month deadline for filing Form M-706 and paying the estimated tax is one of the hardest administrative deadlines in Massachusetts estate administration — and it starts running from the date of death, not from the date the Personal Representative is appointed.

Managing the inventory, accounting, and tax filings alongside the other benefit claims a Massachusetts survivor must pursue is a multi-month administrative project. The Massachusetts Survivor Benefits Navigator provides the complete chronological workflow — from the first week's urgent notifications through the probate accounting and final distribution — so every deadline and filing requirement is tracked in one place.
