How and at what point in time did Rachel become Ya'aqov's wife

Answer From The Annual Reading Schedule - Week 7 Notes For Genesis: This is somewhat debatable, but I consider it possible that Rachel and Ya'aqov became officially husband and wife from the point in time that Lavan (Laban) and Ya'aqov made an agreement that Ya'aqov would serve Lavan 7 years for Rachel. This time appears to be the beginning of their betrothal. It appears according to Deuteronomy 22:23-24 that those who are betrothed are considered husband and wife. They were not yet one flesh, but it does appear there was an agreement that appears similar to a betrothal.
