What are the requirements for applying for a NON-O visa based on marriage at the Thai embassy in London?

Recent discussions indicate that to apply for a NON-O visa based on marriage from the Thai embassy in London, applicants are generally required to show a balance of £10,000, equating to approximately 400,000 baht. However, some users reported that only a recent balance statement might be sufficient, without the need to show a three-month account history. There are also mentions of a distinction between the single entry and multiple entry visa requirements, with some suggesting that the £10,000 may not be mandatory for a single entry visa. Conflicting experiences indicate different submission approaches may work, and clarification may be needed for specific financial disclosures for 90-day visas.
