A list and searchable database of unclaimed funds is available through the Department of the Treasury for the State of New Jersey. The site managed by the State of New Jersey links to an outside site that is endorsed and works with a number of states to help people find their money or the money of family members that have passed. The National Association of Unclaimed Properties Administrators also provides search options for the state.
There are a number of verification forms that someone must provide and fill out to verify who they are and that they are entitled to the money. Decedents must provide verification that it was their family member that was entitled to the money normally by providing their death certificate, social security number and other documents accepted by the state.
