Series 6 Customer Account Types

Individual, joint, custodial, corporate, partnership, and trust account types tested on the Series 6 exam.

Account-type questions test whether the representative understands who legally controls the assets and who has authority to act. That matters because the same investment recommendation may be handled differently depending on whether the account is individual, joint, custodial, trust-based, or owned by a legal entity.

The strongest answer identifies the ownership form first, then asks what documents or authority support the action in the fact pattern.

Key Takeaways

  • Account type determines authority, transfer treatment, and documentation needs.
  • Joint, custodial, and trust accounts are common Series 6 distinction traps.
  • The safest answer is the one that respects the legal ownership structure before taking action.
