Do Thai embassies accept standard marriage and birth certificates for dependents applying for a DTV visa?

DEPENDENT VISAS

I’m applying for a DTV visa at the Thai Embassy in Jakarta. Once that’s approved, my husband and child will apply as my dependents.

I already have our Brazilian marriage certificate and my child’s Brazilian birth certificate. Since Thailand is not part of the Hague Apostille Convention, I was told these documents would normally need extra legalization. This would cost me around 800 USD.

Before I spend that, I’d really like to know: for dependents, have embassies actually required fully legalized documents, or have standard certificates + translations been accepted in practice?

Any experiences in Jakarta (or elsewhere) would be super helpful. Thanks a lot! 🙏
