Do both spouses need to register for classes under the Thai DTV visa, or is one registration sufficient?

For couples applying for the Digital nomad DTV visa in Thailand, only one spouse needs to register for the required soft power activity, while the other can be included based on their marriage. It's generally not necessary to maintain ongoing activity checks after the initial visa approval, but individual financial documentation is still required. If applying for an Education visa, both spouses must apply separately.
