What is source of funds?

Source of funds (SoF) refers to the origin of the specific funds used in a particular transaction or business relationship. Verifying the source of funds is a key component of CDD and EDD, requiring businesses to understand where the money for a specific transaction came from and whether it is consistent with the customer's known financial profile.

SoF vs source of wealth

Source of funds relates to the specific transaction; source of wealth relates to the customer's total accumulated wealth. Both may need to be verified, particularly for PEPs and higher-risk customers. Real estate transactions commonly require SoF verification to confirm the deposit and purchase funds are from legitimate origins.
