unclaimed property best practices, unclaimed property compliance

Nearly every state requires relationship code values on unclaimed property (e.g. bank accounts, insurance policies, checks) records, according to NAUPA (The National Association of Unclaimed Property Administrators) standards.

Relationship codes are used in electronic reporting (NAUPA format) to tell states how owners are linked on an account when the report pertains to unclaimed property. Unclaimed usually refers to property that is dormant, unclaimed due to moving, or following the death of an account holder. With variations by state, relationship codes clarify ownership and allow claims to be properly processed and pay out the property to the rightful owner.

In this blog, we’ll go over what unclaimed property relationship codes are, how to find them, and how to use relationship codes.

  • Relationship codes define how owners are linked in unclaimed property records
  • Relationship codes determine claim payments and prevent disputes
  • NAUPA relationship codes are widely recognized as standard, but states may have their own variations
  • Common codes include SO (sole owner), AN (and), OR (or)
  • Using the wrong unclaimed property record reporting codes can delay filings or cause compliance issues

What “Relationship Codes” Mean and Why They Matter

What are relationship codes in unclaimed property?

“Relationship codes” refer to codes that define owners for a specific property such as accounts, estates, or beneficiaries. These codes facilitate a streamlined process of claims, and NAUPA relationship codes are the standard, although they can vary by state.

Relationship codes help states to pay the right person/s correctly, prevent delays, and are essential for complex situations like trusts where ownership is not always clear.

Common Relationship Codes and Examples

Here are some common NAUPA relationship codes, what they indicate, and examples:

Relationship CodeDescriptionExample
SO (Sole Owner)Indicates a single ownerAn uncashed check made out to John Doe would use the SO relationship code
AN/AND (And)Indicates multiple owners where all named owners are required to claim togetherAn unclaimed checking account belonging to John Doe and Jane Doe where both parties must agree to the claim to claim separately would use the AN/AND relationship code
OR (Or)Indicates multiple owners where any one owner can claim the propertyAn unclaimed savings account belonging to John Doe or Jane Doe could be claimed by either individual solely would utilise the OR relationship code
PO/POA (Power of Attorney)Indicates an agent is authorized to act on behalf of the ownerJohn Doe is the owner of an unclaimed bank account, and his daughter Jennifer Doe submits a claim using a valid POA. A PO/POA relationship code would be used in this instance
EX (Executor/Executrix)Indicates the person appointed to manage the property of the deceasedJane Doe is named as the executor of John Doe’s estate, and upon his death the claim filed with the state would use the EX relationship code
CU (Custodian)Indicates a person appointed to manage property for a minorAn account for a minor (Jack Doe) and managed by John Doe would be recorded using the CU relationship code
JT (Joint Tenants)Indicates multiple owners with right of survivorshipA property jointly held as “John Doe, Jane Doe” which states that the surviving owner inherits the property upon the other owner’s death, JT would be the relationship code in this instance
FBO/BF (Beneficiary)Indicates the person named to receive the propertyIn the case of a life insurance policy where Jane Doe is named as beneficiary, the FBO/BF relationship code would be used

 

How to Find the Proper Relationship Code for Your State 

There are state specific relationship codes (unclaimed property), including sole owner, and/or relationship codes. The NAUPA website search tool provides a state-by-state overview for unclaimed property, which includes state specific relationship codes.

Most states utilise the NAUPA II electronic format, which relies on these codes, however states often add, change, or omit certain NAUPA codes, so it’s important to consult your specific state’s unclaimed property holder manual for the definitively correct relationship codes.

Sovos can help too, as we offer state-specific reporting information as part of our compliance resources.

State-by-State Resources & How to Use Them 

State-specific resources can be found on their treasury or controller website, often referred to as a “treasure hunt” when attempting to find relationship codes for unclaimed property.

The NAUPA website lets you use their free service to search many states simultaneously and has an interactive map to find your state’s official unclaimed property program. You can also find guidance on USA.gov for different types of unclaimed funds.

Tips When State Rules Don’t Match NAUPA Codes

State-specific requirements always take precedence when it comes to unclaimed property relationship codes. Consult the specific state’s unclaimed property resources which outline which NAUPA codes are accepted, which relationship codes are used instead, and any other formatting or data requirements.

Ensure that you verify the relationship code requested by the state for the specific unclaimed property, as they may vary. Data consistency and formatting is also important for non-NAUPA codes; make sure name and field formats match, avoid mixing formats, and use relationship codes to link accounts properly.

The best tip for navigating state-specific relationship codes is to use reporting software and compliance tools to manage the variations between state requirements and the NAUPA standard.

Best Practices for Using Relationship Codes in Reporting

When reporting using relationship codes for unclaimed property, NAUPA standard codes are best practice, however checking state variations is crucial.

The codes used must also apply consistently across all records, such as using SO for Sole Owner in all reports pertaining to that instance. All owner verification must be checked thoroughly (including names and IDs) to ensure no inaccuracies or errors are reported, which can lead to delays and rejections.

Conclusion

Relationship code compliance can be complex, as different states may require different codes for unclaimed property reporting and claims. When incorrect or inconsistent relationship codes are used, claims can be delayed or rejected, so ensuring that your state’s codes are aligned with NAUPA standards or verifying their chosen codes is key.
