Search Connecticut's Big List and Turn a Possible Match Into a Valid Claim
Connecticut unclaimed property can include forgotten bank accounts, uncashed checks, utility deposits, refunds, insurance proceeds, liquidated securities and other money turned over to the Office of the Treasurer after a business loses contact with the owner.
This guide shows how to search old names, recognize a meaningful match, understand CT Big Match and FastTrack-style automatic matching, build ownership proof, claim for a deceased person or business, understand Connecticut's 90-day claim review rule and avoid giving away part of your money to an unnecessary locator.
Start with CT Big List, then verify the result before claiming
Search your current name, former surnames, businesses and deceased relatives separately. A plausible result should connect with something in your history—an old address, financial institution, employer, insurer, utility or other holder.

Connecticut unclaimed property is financial property—not abandoned real estate
The Unclaimed Property Division safeguards assets that businesses transfer to the Treasurer after losing contact with an owner for the applicable period.
Why a company eventually transfers the asset
Connecticut's Treasurer describes a typical period of roughly three to five years during which the holder has lost contact with the customer. Exact abandonment rules vary by property type.
CT Big Match can return some money without making you file a normal claim
Automatic matching for certain sole owners
Connecticut launched CT Big Match to identify qualifying property where the state can confidently match a sole owner with a current address.
How CT Big Match works
Search names from your financial history—not only the name on today's ID
Search sequence that catches more real matches
No result found? Change the search before deciding there is no property
A Connecticut claim should create an obvious chain from the listed owner to you
Organize evidence around three questions
Useful records to gather before starting
The Treasurer must consider each filed claim within 90 days
If a claim is denied
For a deceased owner, finding the account is easier than proving who inherits it
The deceased person's name should normally be searched first. After locating property, the claimant must establish why they are legally entitled to receive it.
Prepare the estate, probate, fiduciary or beneficiary documentation that identifies who has authority over the deceased owner's property.
Connecticut law allows direct payment in certain circumstances for solely owned unclaimed property of a deceased owner valued at less than $500 in the aggregate without requiring the claimant to obtain some traditional probate documents.
Do not confuse the $500 rule with automatic inheritance
Estate preparation checklist
CT Big List is not only for individuals
Connecticut has specifically highlighted corporations, municipalities, schools, nonprofits, hospitals and small businesses as potential unclaimed-property owners.
Search these business identities
The original asset may have been converted before you claim it
Connecticut law permits the Treasurer to sell certain non-cash unclaimed property. Holders are also required to warn owners that securities, virtual currency or tangible safe-deposit property may be liquidated before or after reporting.
You can file directly for free before giving part of your money to a locator
Connecticut generally caps covered locator compensation at 10%
Connecticut law imposes timing restrictions, fee limits and disclosure rules on agreements used to locate or recover unclaimed property.
- The covered fee may not exceed 10% of recoverable property.
- Agreements entered on or after January 1, 2025 must be written and signed.
- The agreement must clearly disclose the property's nature and value.
- It must show the owner's share after fees.
- It must explain that the owner can file directly with the Treasurer at no cost and tell the owner how to do so.
