The verb to handfast in the sense of "to formally promise, to make a contract" is recorded for Late Old English, especially in the context of a contract of marriage. The derived handfasting is for a ceremony of engagement or betrothal is recorded in Early Modern English. The term was presumably loaned into English from Old Norse handfesta "to strike a bargain by joining hands"; there are also comparanda from the North Sea Germanic sphere, Old Frisianhondfestinge and Middle Low Germanhantvestinge. The term is derived from the verb to handfast, used in Middle to Early Modern English for the making of a contract.
