Documents You’ll Need To Claim Unclaimed Assets in Maine

Finding out you may have unclaimed money or property in Maine can be a pleasant surprise—but actually getting it back usually requires the right documents. This guide explains the typical paperwork Maine residents are asked to provide, how to prepare it, and what to expect when claiming unclaimed assets through official state channels.

What Are Unclaimed Assets in Maine?

In Maine, unclaimed assets (also called unclaimed property) usually refers to money or property that a business or institution has been holding for you but lost contact with you for a certain period of time. After that period, they are required to turn it over to the state.

Common examples include:

  • Bank accounts and credit union accounts
  • Uncashed checks (payroll, refunds, insurance benefits)
  • Security deposits (utilities, landlords)
  • Insurance proceeds and benefits
  • Stocks, dividends, and mutual funds
  • Contents of safe deposit boxes
  • Gift cards or store credits (in some cases)

The Maine unclaimed property program holds these assets until the rightful owner or heirs come forward and file a claim.


Who Can Claim Unclaimed Assets in Maine?

The documents you’ll need depend on who you are in relation to the property:

  • Original owner (the person listed on the account or check)
  • Current or former name of the owner (for example, you married and changed your last name)
  • Heir or beneficiary of a deceased owner
  • Executor or personal representative of an estate
  • Business owner or authorized company representative
  • Guardian, conservator, or power of attorney (in certain circumstances)

Each situation requires proof of identity plus proof of your right to the property. The sections below outline typical document lists for each category.


Core Documents Almost Everyone Needs

Most claims in Maine require at least some combination of the following basic documents:

  • Proof of identity
  • Proof of your current address
  • Proof of connection to the property or the owner

The table below summarizes what is usually expected:

PurposeCommon Documents Accepted*
Prove who you areDriver’s license, state ID, passport, military ID, or other government-issued photo ID

Claiming for a businessBusiness registration, articles of incorporation, partnership agreement, proof of authority

*Exact requirements can vary by claim type and amount. The official Maine unclaimed property office decides what is acceptable in your situation.


Documents for Individuals Claiming Their Own Property

If you are the person whose name appears on the unclaimed asset, you are usually asked to provide:

1. Proof of Identity

Most commonly:

  • Valid government-issued photo ID, such as:
    • Maine driver’s license
    • Maine state ID card
    • U.S. passport
    • Military ID

If your ID is expired, the state may still accept it or may ask for additional documentation. Check the instructions from the Maine unclaimed property office for current rules.

2. Proof of Current Address

If the address on your ID matches the address related to the unclaimed property, that may be enough. If not, you might be asked for separate proof, such as:

  • Utility bill (electric, gas, water, internet)
  • Bank statement or credit card statement
  • Lease agreement or mortgage statement
  • Property tax bill
  • Official government mail (for example, IRS or Social Security letters)

These documents typically need to:

  • Show your name
  • Show your current address
  • Be recent (often within the last 3 months, but check the instructions)

3. Proof You Lived at the Old Address (If Different)

If the unclaimed asset is tied to an old address, Maine may ask you to prove you once lived there. Common options include:

  • Old utility bills with your name and that address
  • Old bank statements or credit card statements
  • Pay stubs or W‑2 forms
  • Old lease agreements
  • Prior tax returns with that address
  • Official mail sent to you at that address

If you no longer have old documents, you may need to:

  • Ask your former bank, employer, or landlord for old statements or records
  • Check old email accounts or saved files for PDFs
  • Look for old tax documents or pay statements

Documents for Name Changes (Marriage, Divorce, or Legal Change)

If the unclaimed property is in a different name than the one on your current ID, you usually must show the legal link between those names.

Typical documents:

  • Marriage certificate
  • Divorce decree showing name change
  • Court order granting a legal name change
  • Adoption records (when relevant)

You may need to submit:

  1. Your current ID (with your current legal name)
  2. The name change document connecting your current name to the name on the unclaimed asset

For multiple name changes over time, you may need documents for each step connecting all names.


Documents for Claiming on Behalf of a Deceased Person

If the original owner has died, Maine usually requires extra documentation to show both:

  1. Proof of the person’s death
  2. Proof of your legal right to their property

1. Proof of Death

Typical document:

  • Certified death certificate

Some situations may allow other official notices, but a death certificate is the most common requirement.

2. Proof of Relationship or Legal Authority

Depending on whether there was a will and whether the estate went through probate, you may need:

  • Will naming you as a beneficiary
  • Letters testamentary (if you are the executor of a will)
  • Letters of administration (if you are appointed to manage an estate without a will)
  • Personal representative appointment papers from probate court
  • Heirship documentation, which might include:
    • Affidavits of heirship
    • Family tree information
    • Other documents requested by the state

If the estate is small or never went through probate, Maine may have simplified procedures. The official unclaimed property office or local probate court can explain what’s typically used for small estates.

3. Your Own Identity Documents

You will still need to prove who you are, usually with:

  • Government-issued photo ID
  • Possibly proof of your address

4. Proof of the Deceased’s Address and Ownership

The state may ask for evidence that:

  • The deceased person lived at the address tied to the property
  • The deceased owned or was owed the asset

Documents may include:

  • Old statements, policies, or correspondence showing the deceased’s name and address
  • Bank statements, insurance policies, or retirement account statements
  • Employer records or pension documents

In inheritance cases, requirements can be more detailed. If documents are missing or complicated, Maine may request additional paperwork or explanations.


Documents for Business or Organization Claims

If the unclaimed asset belongs to a business, nonprofit, or other organization registered in Maine, you will generally need to show:

1. Proof of Business Existence

Examples include:

  • Articles of incorporation or articles of organization
  • Partnership agreement
  • Business registration or charter
  • Certificate of good standing (sometimes requested)

These documents help prove the business is real and matches the name on the property.

2. Proof of Your Authority to Act

You usually must show that you are allowed to claim money on behalf of the organization. That might include:

  • Corporate resolution naming you as an authorized representative
  • Board meeting minutes granting authority (for nonprofits or corporations)
  • Letter on company letterhead, signed by an officer, authorizing you
  • If you are the owner, documents showing ownership, such as:
    • Partnership agreement
    • Operating agreement (for LLCs)
    • Stock certificate or shareholder record (for corporations)

You will also need your personal ID, like a driver’s license.

3. Proof of Business Address or Connection

To link the business to the unclaimed asset:

  • Business bank statements
  • Invoices or bills in the company’s name
  • Utility bills for the business
  • Tax returns or payroll records

If the business has changed names, merged, or dissolved, you may need documentation of the name change or merger.


How to Find Out What Documents You Personally Need

Even in Maine, document requirements can vary by:

  • Type of asset (check vs. safe deposit box, for example)
  • Claim amount (small vs. large claims)
  • Whether it’s an individual, estate, or business claim
  • How clear or complicated the ownership situation is

To get instructions that match your exact claim, you can:

  1. Search for your name or business name using the official Maine unclaimed property search tool or office.
  2. View the details of any property listed under your name.
  3. Start the claim process through the official website or paper forms.
  4. Carefully read any checklists or instructions they provide for your claim type.

The official Maine office may list required documents right on the claim form or in the online portal.


How the Typical Claim Process Works in Maine

Although exact steps can change, many people in Maine go through this general process:

  1. Search for unclaimed property

    • Use the state’s official unclaimed property website or contact the Maine State Treasurer’s Office.
    • Search by your name, former names, or business name.
  2. Select the property to claim

    • Confirm the address, business name, or other details match you or your relative.
  3. Choose how to file your claim

    • Some claims can be submitted online.
    • Others may require printed forms you mail in.
    • In some cases, you may be allowed to submit documents in person at a state office.
  4. Gather and submit documentation

    • Follow the document checklist given by the Maine unclaimed property office.
    • Make sure copies are clear and readable.
    • Never send your only original of important documents unless the state explicitly requires it and you understand the risk.
  5. Wait for review

    • The office reviews your claim and may contact you for more documents or clarification.
    • Processing times vary depending on volume and complexity.
  6. Receive payment or property

    • If approved, you may receive a check, have funds deposited, or receive instructions for retrieving tangible property, such as safe deposit box contents.

Common Reasons Maine Unclaimed Property Claims Are Delayed or Denied

People sometimes experience delays or denials because of issues that are often fixable. Common problems include:

  • Incomplete forms

    • Missing signatures, unanswered questions, or skipped sections.
  • Missing required documents

    • Not including death certificates, name change records, or proof of old addresses.
  • Unclear copies

    • Blurry photos, cut-off pages, or unreadable scans.
  • Name mismatches

    • Claim filed under a different spelling or name with no legal documentation to connect them.
  • Wrong person claiming

    • Person filing the claim cannot legally show they are the owner, heir, or authorized representative.
  • Out-of-date contact information

    • The office cannot reach you for follow-up questions or additional documentation.

If your claim is denied or the state asks for more information, you can usually:

  • Review the explanation provided in the denial or status letter
  • Gather any missing records
  • Resubmit your claim or file a new one with the correct documentation
  • Contact the Maine unclaimed property office for clarification on what’s needed

How Reviews, Reconsiderations, or Appeals Usually Work

If you disagree with a decision on your claim, options typically include:

  • Request clarification

    • Call or write to the Maine unclaimed property office to ask exactly why the claim was not approved.
  • Submit additional evidence

    • Provide documents that were missing or add more detailed proof of identity, relationship, or address history.
  • Ask about a formal review or appeal

    • Some states allow a more formal review process if you still disagree after providing more information.
    • The office can explain whether Maine has a specific appeal process and how to use it.

Because each claim situation can be unique, it can help to keep copies of everything you send and any letters you receive from the state.


Tips for Gathering Documents Efficiently

To speed up your Maine unclaimed asset claim, it often helps to:

  • 🔍 Make a list of names and addresses

    • Include all past names and addresses you (or the deceased person) used in Maine and elsewhere.
  • 📁 Create a dedicated folder

    • Keep ID copies, bills, bank statements, court documents, and official letters together.
  • 📝 Write short notes for complicated histories

    • If there were multiple marriages, moves, or business changes, a simple timeline can help you figure out what documents you need.
  • 📸 Use clear scans or photos

    • Ensure text is readable, corners aren’t cut off, and any seals or signatures are visible.
  • 🕒 Check dates

    • Some documents may need to be recent (like current address proof); others just need to show that you once lived or worked somewhere.

How to Verify You’re Using an Official Maine Channel (Scam Avoidance)

Because unclaimed money sounds appealing, scammers sometimes pretend to “help” people claim assets for a fee or to steal personal information. You can reduce your risk by:

  • Being cautious of:

    • Unexpected emails, texts, or social media messages offering to claim money for you
    • Requests for upfront fees to search for or release unclaimed property
    • Messages asking for sensitive data like your full Social Security number or bank PINs through unofficial channels
  • Verifying you’re on the official Maine site or office by:

    • Checking that the website clearly identifies a Maine government agency, such as the state treasurer’s office
    • Confirming phone numbers and addresses through a trusted source, like:
      • The Maine State Government’s main website
      • Printed materials from state offices
      • A call to 211 (which may provide state resource information in many areas)
  • Remembering:

    • You typically do not need to pay a fee to search for or claim unclaimed property directly through the state.
    • If someone charges you to search or file, you can often do the same steps yourself through official channels at no cost.

If You Don’t Qualify or Cannot Prove Ownership

Sometimes a person finds a listing that looks like it might be theirs, but they cannot produce enough documentation to prove legal ownership. When that happens:

  • You can:

    • Ask the Maine unclaimed property office whether any alternative documents will be accepted.
    • Double-check with:
      • Former landlords or employers
      • Banks or financial institutions
      • Family members who may have old records
  • If the state still can’t verify ownership:

    • They may keep the property on hold under the owner’s name until sufficient proof is provided.
    • You may need to wait until you can gather additional records, especially in complex inheritance or business situations.

Keep in mind that unclaimed property generally stays under state custody indefinitely, waiting for the rightful owner or heirs to come forward with sufficient proof.


By understanding which documents are commonly required and preparing them before you file, you can make your Maine unclaimed asset claim smoother and faster. For the most accurate, up-to-date instructions, always rely on Maine’s official unclaimed property office, its official website, or its published forms and instructions, since those are the authorities that review and approve claims.
