Here is the sentence that surprises most nomad parents: Thailand does not have a single family visa.
Each adult has to qualify on their own. Children are usually added as dependants to a parent's status, and their permission to stay mirrors yours. If you switch visa type later, the child often needs a fresh dependant application too. A household can end up holding two or three different visa types at once, and that is normal.
For a remote-working parent, the usual route is the Destination Thailand Visa (DTV). One consultancy guide lists a savings requirement of THB 500,000 and a five-year, multiple-entry validity. Treat those numbers as a starting point, since rules and fees shift. Check the official Ministry of Foreign Affairs checklist. A non-working partner may be able to apply as a dependant under a Non-O, provided the relationship is documented and the finances meet the threshold.
Three practical things are easy to miss:
1. 90-day reporting. DTV, Non-B and Non-O holders file a report every 90 days, even if you never leave Thailand. 2. TM30. Your landlord must notify immigration of your address within 24 hours of move-in. Confirm it happened, because it affects your reporting. 3. Work limits. DTV holders cannot work for a Thai employer. Remote work for a foreign employer is fine.
A note on the source: it is written by a visa consultancy, so it also sells services. The structure it describes matches what many families report, but verify the specifics yourself.
Start the paperwork before you commit to a lease or a school place. Documents like marriage and birth certificates take the longest to organise.
