What is a joint account?¶

A joint account is held by two or more people, each with rights defined by the mandate. Joint ownership does not mean every holder participated in every transaction.

Formal authority can coexist with different use¶

Holders may have separate cards, endpoints and sessions or share them. One can be the usual operator while another has little practical involvement. Funds may also come from different sources, so credit into the account does not establish which holder owned or benefited from it.

Attribute the disputed event¶

Obtain mandate and holder details, card allocations, endpoints, logins, IP-related records, authentication and approvals. Compare each holder's devices, location, communications and normal behaviour.

Test denials against the records rather than shifting responsibility to another holder automatically. Report joint-account activity and name a user only where evidence resolves the transaction-time operator.
