。
She seized my fortune from me.
Literal
She [topic-は] me [from-から] fortune [object-を] seized.
奪い取る is a compound verb of intensification: 奪う ('to snatch, to rob') + 取る ('to take') — 'forcibly seize.' The 取る at the end of compound verbs frequently adds a 'to grasp, to come into possession of' nuance to the base verb. 財産 ('property, fortune, estate') is a serious word for accumulated wealth — material possessions, real estate, holdings. The から marks the source: 私から ('from me'). The whole sentence has a melodramatic edge — fitting a novel or news story rather than chat.
