What are the financial evidence requirements for dependent visa applications in Thailand?

When applying for dependent visas in Thailand, the requirement for financial evidence can vary. In this case, the primary applicant holds a Digital Nomad Visa (DTV) and is seeking clarification on whether a sponsor letter and a bank statement showing 500,000 THB for three months is sufficient for his wife and daughter. Responses indicate that some applicants have successfully used a single 500,000 THB bank statement along with a sponsor letter for their dependents. However, it's also suggested to have at least 1,000,000 THB, as requirements may differ by embassy.
