Documents You Need To Claim Unclaimed Property in New Hampshire

If you discover unclaimed money or property in your name in New Hampshire, your next question is usually: “What documents do I need to claim it?” This guide explains, in plain language, the typical paperwork New Hampshire residents are asked for, how to get it together, and what to expect when you submit your claim through official state channels.

HowToGetAssistance.org is not a government office or claim portal. This article is meant to help you understand the process so you can work more confidently with the official New Hampshire unclaimed property office.


Understanding Unclaimed Property in New Hampshire

Unclaimed property usually means money or financial assets that were left inactive for a set period of time, then turned over to the state. Common examples include:

  • Old bank accounts or certificates of deposit
  • Uncashed checks (payroll, refunds, dividends)
  • Utility deposits or credit balances
  • Insurance benefits
  • Safe deposit box contents
  • Stocks, bonds, or mutual fund shares

In New Hampshire, these assets are typically handled by the state’s unclaimed property division, usually under the state treasury. You do not lose ownership rights just because the property was turned over to the state, but you do have to prove you are the rightful owner or heir.

That proof is where documents come in.


Big Picture: What Documents Are Usually Required?

The exact documents depend on:

  • Whether you’re claiming for yourself, your business, or a deceased person
  • The type and value of the property
  • Whether your name or address has changed

Most people should expect to provide:

  • Identity documents (to show you are who you say you are)
  • Address documents (to show your connection to the address listed in the claim)
  • Ownership or relationship documents (to show your right to the property)

The state’s official claim form or online system usually lists the required documents for that specific claim, but the sections below walk through the most common scenarios so you can prepare in advance.


Core Documents Most Individual Claimants Need

1. Proof of Identity

You’ll almost always need at least one current, government-issued photo ID. Common options include:

  • Driver’s license (New Hampshire or another state)
  • State-issued ID card
  • U.S. passport
  • Military ID (sometimes accepted)

If you don’t have a current, valid photo ID, the unclaimed property office may accept alternative identification, such as:

  • Birth certificate plus a secondary ID (such as a Social Security card)
  • Permanent resident card
  • Other government-issued documents

Because requirements can change, it’s best to check what forms of ID are currently accepted through the official New Hampshire unclaimed property office before you submit your claim.

2. Proof of Social Security Number (Sometimes Required)

For some claims, especially for larger amounts, you may be asked to verify your Social Security number. Typical documents include:

  • Social Security card
  • Official tax document (such as a W-2 or 1099 showing your full name and SSN)
  • Medicare card (if it shows your SSN)

Not every claim requires this, but be prepared in case it’s requested.

3. Proof of Address (To Match the Claim Record)

Because unclaimed property records often list an old address, New Hampshire often asks for documents that prove:

  1. You lived at the address listed on the claim, and/or
  2. Your current address, so they can mail your check or contact you.

Common proof-of-address documents include:

  • Utility bills (electric, gas, water, internet)
  • Bank or credit card statements
  • Lease agreement or rental contract
  • Mortgage statements or property tax bills
  • Pay stubs with your address
  • Official government mail (tax notices, benefit letters)

To be useful, the document usually needs to show:

  • Your name
  • The relevant address
  • A date (often within a certain time frame, or from the period when the property went unclaimed)

If you no longer have records from the time of the unclaimed property (for example, a 20-year-old apartment), you can still submit a claim, but the unclaimed property division may ask follow-up questions or request other documentation.


Name Changes, Marriage, and Other Identity Differences

If the name on the unclaimed asset does not exactly match your current legal name, you usually need to show how the names connect. This happens often after marriage, divorce, or legal name changes.

Common supporting documents include:

  • Marriage certificate (to link a maiden name to a married name)
  • Divorce decree (if it shows the name change)
  • Court order of name change
  • Adoption records (for some situations)

These records should clearly show both the old name and the new name so the state can see the connection.


Claiming Unclaimed Property for a Deceased Person (Heirs & Estates)

If you are trying to claim unclaimed assets for a deceased relative, expect to provide additional documents. The complexity depends on:

  • The value of the property
  • Whether there is a will
  • Whether the estate has gone through probate in court

Common Documents for Deceased Owner Claims

Typical documents may include:

  • Death certificate of the original owner
  • Proof of your relationship to the deceased (such as a birth certificate, marriage certificate, or other legal documents)
  • Will or letters testamentary (documents showing the court-appointed executor)
  • Letters of administration or other court orders (if there was no will)
  • Small estate affidavit (if New Hampshire allows this option for smaller amounts)

The specific paperwork can vary by:

  • How New Hampshire’s probate process works
  • Whether the claim is under a small estate threshold
  • Whether there are multiple heirs

In many cases, the executor or administrator of the estate is the person who files the claim. If you are an heir and not the executor, the state may require consent forms or other documentation showing your authority to claim on behalf of other heirs.


Claiming on Behalf of a Business, Trust, or Organization

For businesses, trusts, or nonprofit organizations, you usually need to show:

  1. That the entity exists or existed, and
  2. That you are authorized to act on its behalf.

Typical Documents for Business Claims

  • Business formation documents (articles of incorporation, articles of organization, partnership agreements)
  • Proof of EIN (Employer Identification Number), such as:
    • IRS letter assigning the EIN
    • Recent tax return in the business’s name
  • Business license, if applicable
  • Documentation showing you are an authorized officer or representative, such as:
    • Corporate resolution
    • Meeting minutes
    • Letter on company letterhead, signed by an officer
  • Proof of the business’s address (utility bills, bank statements, lease agreements in the company’s name)

Typical Documents for Trust Claims

  • Trust agreement or declaration of trust (showing the name of the trust and trustee)
  • Documentation appointing you as trustee (if not clear in the original agreement)
  • Proof of the trust’s tax ID number (if applicable)

Because entity claims can be more technical, New Hampshire’s unclaimed property office often provides specific instructions for business and trust claims. It’s usually helpful to review those official instructions carefully.


Quick Reference: Common Claim Situations and Documents

Below is a simplified overview. Your exact situation may need more or fewer documents depending on state requirements.

How and Where to Submit Your Documents

New Hampshire typically allows claims to be filed:

  • Online through the official state unclaimed property portal
  • By mail, using an official claim form
  • Sometimes in person at a state office (depending on state procedures)

Because HowToGetAssistance.org is not a claim portal, you will need to:

  1. Locate the official New Hampshire unclaimed property website or office.

    • Search for terms like “New Hampshire unclaimed property” followed by “treasurer” or “state government.”
    • Confirm that the website has a “.gov” address or is clearly a state government site.
  2. Start your claim through the official portal or form.

    • The portal usually creates a claim number and tells you what documents to upload or mail.
  3. Follow the document instructions closely.

    • Some documents must be copies, others may need to be notarized or originals.
    • If you mail originals, consider using a trackable mail service and keep copies for your records.

What Happens After You Submit Your Documents

Once you submit your claim and documents to the official New Hampshire unclaimed property office, typical next steps include:

  1. Review by the state

    • Staff verify your identity and your connection to the property.
    • They may compare your information to tax records, prior addresses, or other state data.
  2. Requests for additional information (if needed)

    • If something is missing or unclear, they may send you a letter, email, or portal message asking for more documentation.
  3. Approval and payment

    • If approved, you may receive a check, a reissued payment, or instructions for handling securities (stocks, bonds, etc.).
  4. Denial or partial approval

    • If they cannot verify your claim, they may deny it and explain why.
    • In some cases, they might approve only part of a claim if they can verify only part of the information.

Processing times can vary based on:

  • The number of claims the office is handling
  • How complete and clear your documents are
  • Whether your claim involves an estate, business, or trust, which can take longer

Common Reasons Claims Get Delayed or Denied

Being aware of common problems can help you avoid them:

  • Missing or expired ID
    • Submitting an old, expired driver’s license without anything else
  • No proof of address matching the unclaimed property record
    • Especially if your name is common and the address is the only clue
  • Unclear relationship to a deceased person
    • No proof you are the heir, or incomplete estate documents
  • Inconsistent information
    • Different spellings of your name, different birthdates, or mismatched SSNs
  • Incomplete forms
    • Missing signatures, blank fields, or not answering required questions

If your claim is denied or delayed, New Hampshire’s unclaimed property division usually provides instructions on what additional documents or steps might resolve the issue.


Can You Appeal or Ask for a Review?

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

  1. Contact the unclaimed property office directly

    • Ask for clarification about why the claim was denied or delayed.
    • Sometimes the issue can be resolved by submitting another document or correcting a mistake.
  2. Request a review or reconsideration

    • Some states have a more formal appeal or review process for unclaimed property decisions.
    • The state may outline how to make a formal request in writing.

If you are dealing with large amounts or a complicated estate, you might choose to consult an attorney familiar with New Hampshire probate and property law. That decision is personal and may depend on the value of the asset and how complex the documentation is.


Tips to Get Your Documents in Order Before You Claim

A little preparation can make your claim smoother:

  • Gather ID and address documents first.

    • Make sure your ID is current and shows your correct legal name.
  • Collect older documents if you can.

    • Old leases, paystubs, utility bills, and tax returns can sometimes prove you lived at a prior address linked to the unclaimed asset.
  • Organize estate paperwork if the owner is deceased.

    • Keep the death certificate, will, and any court orders together and easy to access.
  • Make copies of everything you send.

    • Keep a personal file so you know exactly what you submitted.
  • Respond quickly to requests from the official office.

    • Delays in sending additional documents can slow the entire process.

How to Confirm You’re Using an Official New Hampshire Channel

Because unclaimed money can attract scams, it’s important to verify you’re working with the real state office, not a third-party service pretending to be official.

Here are practical safeguards:

  • Look for “.gov” in the website address, which usually indicates an official government site.
  • Check that the website clearly identifies the State of New Hampshire and the Treasury or Unclaimed Property Division.
  • If you’re unsure, use a trusted number such as 211 to ask for the correct state office contact information.
  • Be cautious about:
    • Websites or callers who demand upfront fees to “get your money faster”
    • Requests for sensitive information through unsecured email or unexpected links
  • If you received a letter or call about unclaimed property, you can independently look up the state unclaimed property office’s phone number from a government directory and call them directly to confirm.

You can choose to use private “finder” services if you want, but New Hampshire typically allows you to claim your own property directly with the state at no charge, apart from any mailing or notary costs you choose to incur.


With the right documents in hand—proof of identity, address, and ownership or relationship—you’re usually in a strong position to move forward with an official unclaimed property claim in New Hampshire. The state’s unclaimed property division is the final authority on what they will accept, so always follow the instructions you receive from their official website, forms, or staff.
