I'm just starting to learn and review ready reserve loans (overdraft loan)and am trying to figure out if it is a requirement to collecte marital status this type of loan.
Can anyone help?

Thanks!!

Here is a citation from Regulation B (§1002.5(d) regarding marital status inquiries:

(d) Other limitations on information requests. (1) Marital status. If an applicant applies for individual unsecured credit, a creditor shall not inquire about the applicant's marital status unless the applicant resides in a community property state or is relying on property located in such a state as a basis for repayment of the credit requested. If an application is for other than individual unsecured credit, a creditor may inquire about the applicant's marital status, but shall use only the terms married, unmarried, and separated. A creditor may explain that the category unmarried includes single, divorced, and widowed persons.

I believe the only time you are REQUIRED to collect that information is if it's subject to 1002.13 of Reg B. Ready reserve loans don't generally fall under that section.
