Do both partners need to provide financial statements when applying for a Non-OX visa in Thailand?

The user inquired about the financial statement requirements for their Non-OX visa application, specifically whether their wife, as a dependent, needs to submit a separate financial statement when their primary account already meets the requirement of having 3 million THB. Responses from the community provided mixed guidance, with one suggesting to check the online application forms for document requirements, another mentioning that the OX visa must be obtained before applying for the dependent visa, and a third asking about the duration of the OX visa.
