@starpixidust well in some instances the dowry is sent with the wife as funds for her to use while she becomes familiar with the estate and how it runs but ultimately the husband has control over the estates financials. Her dowry is from an external source from outside the bubble of the husbands finances and technically he could probably take it for himself but he'd face backlash from her family (if they actually cared). (Most of this is guessing and from reading other manhwa)
