Can I use funds from my bank account while waiting for a Thai visa extension based on marriage?

The user inquired about the rules regarding maintaining the balance of 400,000 baht in their bank account while waiting for a marriage-based visa extension in Thailand. They seek clarification on whether they can use the funds before getting the official passport stamp or if they must keep the balance intact. Responses suggest that while it's advisable to keep the funds until the extension is confirmed, there is no specific rule forbidding access to the funds as long as the required amount is maintained two months prior to the next yearly application.
