Overview
Chapter 9 deals primarily with situations of uncertainty. Unlike earlier chapters that focused on how Kiddushin is created, this chapter addresses cases where we do not know:
- Which woman was betrothed
- Which man is the husband
- Whether an agent completed his mission
- Whether a public report of Kiddushin is true
- Whether conflicting claims should be believed
The chapter is built around one major principle:
When Kiddushin may have taken effect and we cannot identify exactly how, Halachah often treats the situation as doubtful and requires a get to remove the uncertainty.
- Simultaneous Kiddushin of Relatives
Two Women Who Cannot Both Be Married
If a man attempts to betroth simultaneously:
- Two sisters
- A woman and her daughter
- Any pair related by ervah
neither is betrothed.
The Kiddushin fail completely because the act cannot legally identify a permissible recipient.
Many Women Together
If several women are included in one Kiddushin and among them are:
- Two sisters
- Mother and daughter
and he says:
“All of you are betrothed to me”
none become betrothed.
However, if he says:
“Whoever is fit for marriage to me is betrothed”
then all eligible women become betrothed, while the prohibited relatives are excluded.
- “One of You Is Betrothed”
A man says to two sisters:
“One of you is betrothed to me.”
Or he says to a father:
“One of your daughters is betrothed to me.”
The Kiddushin take hold somewhere, but we cannot identify where.
Result:
- Every possible candidate needs a get.
- He may not marry any of them.
This is a classic case of safek Kiddushin.
- Conflicting Actions by Agents
A man appoints an agent to marry a particular woman.
Before learning what happened, he personally marries:
- Her mother
- Her daughter
- Her sister
and we do not know who married first.
Both women require a get.
The uncertainty creates prohibitions for all involved.
- Presumption that an Agent Fulfilled His Mission
One of the Rambam’s most important principles:
“Chazakat shaliach oseh shlichuto”
An agent is presumed to have completed his assignment.
If a man appoints an agent to find him a wife and the agent dies before reporting back:
We assume he fulfilled his mission.
Since no one knows who the woman was, the man becomes restricted from marrying many women because perhaps they are relatives of the unknown fiancée.
- Extreme Cases of Doubt
A remarkable example:
Five sons appoint their father as agent.
Another father has five daughters.
The father says:
“One of your daughters is betrothed to one of my sons.”
No one knows who was paired with whom.
Result:
- Every daughter requires gittin from every son.
- If one son dies, yibbum/chalitzah complications arise.
This demonstrates how uncertainty alone can generate extensive legal consequences.
- Ambiguous References to Daughters
A father says:
“I betrothed my oldest daughter.”
When he has multiple groups of daughters, Rambam interprets the statement strictly:
“Oldest daughter” means:
The oldest of all daughters.
Similarly:
“Youngest daughter” means:
The youngest of all daughters.
Only that one is affected.
- A Father’s Credibility
Before a daughter reaches adulthood, the Torah grants the father special authority.
Therefore the father may say:
“My daughter is betrothed.”
His statement is believed.
The daughter becomes forbidden to everyone else.
Forgotten Identity of the Groom
The father says:
“I married off my daughter, but I do not remember to whom.”
The daughter becomes prohibited to all men.
Later, if he remembers:
“It was this man.”
His identification is accepted.
- Men Claiming to Be the Groom
If one man says:
“I am the groom.”
He is believed.
He may marry her.
If two men each claim to be the groom:
Both give a get.
Alternatively:
- One gives a get.
- The other marries her.
Once she has already married one claimant, later claimants are ignored.
- Woman Claims She Was Betrothed
If a woman says:
“I was betrothed, but I do not know to whom.”
Then a man appears claiming:
“I am the groom.”
He is believed only enough to give a get.
He is not believed enough to marry her.
Chazal feared possible manipulation.
- Conflicting Claims Between Man and Woman
He says: “I betrothed you.”
She says:
“No you did not.”
Then:
- He is forbidden to her relatives.
- She remains permitted to his.
Because he has bound himself by his own statement.
She says: “You betrothed me.”
He denies it.
Then:
- She becomes forbidden to his relatives.
- He remains permitted to hers.
Again, each side is bound by its own admission.
- Witnesses Are Always Required
All these disputes assume the claimant asserts:
“There were witnesses, but they are unavailable.”
Without witnesses:
There is no Kiddushin at all.
This reiterates a fundamental rule from Chapter 4.
- An Agent Who Secretly Marries the Woman Himself
A person appoints an agent:
“Go marry this woman for me.”
Instead, the agent marries her himself.
Legally:
She is married to the agent.
Morally:
The agent is called a wicked person.
The transaction works, but his conduct is condemned.
- Cancellation of Agency
If either side revokes the agency before completion, and it is unknown whether the revocation occurred before the Kiddushin:
The Kiddushin are doubtful.
Therefore:
Safek Kiddushin.
A get is required.
- “I Married One of Five Women”
A man knows he betrothed one of five women, but cannot remember which.
Each woman claims:
“It was me.”
He must:
- Give a get to each woman.
- Avoid all their relatives.
Regarding the ketubah, only one ketubah is actually owed, though special penalties may apply in certain cases.
- The Laws of “Kol” (Public Reputation)
The final section discusses kol, a public report or reputation.
If a strong public rumor develops that:
“This woman became betrothed.”
Halachah may treat her as potentially betrothed even without direct testimony.
Examples include:
- Celebration preparations observed
- Engagement festivities
- Widely reported information tracing back to witnesses
What Is Not a Reliable Kol?
A report that merely says:
“She is going to become betrothed.”
is ignored.
Only a report that the event already occurred has significance.
- Amatla – An Explanation That Weakens the Rumor
Suppose a rumor spreads:
“She became betrothed.”
But simultaneously people explain:
- The Kiddushin were conditional.
- The Kiddushin were doubtful.
- Something invalidated them.
This explanation is called an amatla.
An amatla can weaken or eliminate the force of the rumor.
- Sending Engagement Gifts (Sivlonot)
In places where gifts are normally sent after engagement:
Receiving such gifts creates concern that Kiddushin already occurred.
A get may therefore be required out of doubt.
In places where gifts are normally sent before engagement:
No concern exists.
Local custom becomes legally significant.
- Credibility of Personal Statements
At the end of the chapter Rambam discusses a woman who says:
“I am betrothed.”
and later says:
“I am not.”
or
“I am married.”
and later says:
“I am single.”
If she provides a convincing explanation (amatla) for the original statement, she may be believed.
Without a reasonable explanation, her first statement remains binding.
Major Theme of Chapter 9
Chapter 9 is the Rambam’s great treatment of uncertainty in marriage law.
The chapter teaches that when Kiddushin may have occurred:
- Uncertain identities,
- Uncertain timing,
- Agency complications,
- Public rumors,
- Conflicting claims,
all receive serious legal weight.
At the same time, the Rambam balances that caution with clear rules of credibility, presumptions, and evidentiary standards, creating a structured system for resolving doubt while protecting the integrity of Jewish marriage.
