Can the sin sod (Thai dowry) be used in a scam?
In short
Yes: while sin sod is a real custom in Thai weddings, it's also used as a pretext in online dating scams. The red flag isn't the sin sod itself, but being asked for it as a dowry before ever meeting the family in person, or even before a first face-to-face meeting.
More context
Legitimate sin sod is negotiated between families who already know each other, usually after months or years together, and handed over in person during or before the wedding — never wired remotely to someone with no physical contact yet. In the Thai dating scams documented on this site, the same concept is used differently: it shows up as an urgent money request, framed as "what my family requires for the wedding," aimed at someone who met the other person online and has never been to Thailand or spoken with that family. The signs for telling the two apart are the same as in any dating scam: resistance to video calls, time pressure, and a relationship moving very fast with no in-person meeting. If the family has already been met in person and the relationship has lasted a while, a real sin sod is part of Thai custom, not a scam.
