What is the minimum amount of money required to establish kiddushin?
Halacha 1 states that kiddushin with money requires a p'rutah — in coin or its equivalent worth — given by the man to the woman in the presence of witnesses.
Question 2
If a woman gives a man money and declares 'Behold, I am consecrated to you,' what is the legal status of the kiddushin?
Halacha 2 states that if she gives him money and makes the statement, the marriage bond is not established at all, because Deuteronomy 24:1 ('When a man takes a wife') requires the man to initiate the act.
Question 3
Which of the following formulas creates valid kiddushin?
Halacha 6 lists valid formulas including 'Behold, you are my wife.' Formulas where the man gives himself to the woman (like 'I am your husband') are invalid; 'set aside' and 'earmarked' create only doubtful kiddushin per Halacha 7.
Question 4
When does a father lose his authority to consecrate his daughter?
Halachot 11–12 explain that the father retains authority until she becomes a bogeret or enters nisu'in (completes marriage). Once either occurs — even if she was previously widowed or divorced while still a minor — she is fully independent.
Question 5
When must the blessing of erusin be recited?
Halacha 22 rules that the blessing must be recited before performing the kiddushin, as one recites a blessing before any mitzvah. If omitted and the kiddushin are done, the blessing may not be recited afterward — it would be a blessing in vain.
