How does using a guarantor work for the 500,000 THB requirement in Thailand?

The original question concerns the use of a guarantor for the 500,000 THB financial requirement for a visa in Thailand. Responses indicate that typically the funds must be in the applicant's name in a bank account, and initially, showing the bank statement with the required amount is necessary. If the immigration authorities request additional documentation, such as a salary slip from the last six months, they will ask for these after reviewing the initial submission.
