公證與否沒有很大意義，你隻要有銀行單據證明財產歸屬就可以

公證（notary）其實隻是證明簽字。

A notary is a lawyer or person with legal training who is licensed by the government to perform acts in legal affairs, in particular witnessing signatures on documents. The form that the notarial profession takes varies with local legal systems.[1]
