954. A Wife Making an Eiruv for Her Husband
Eiruvin 5:5
One’s wife may join an eiruv on his behalf without his knowledge so long as he does not want to impede his neighbors’ ability to carry. If that is his intention, she cannot join an eiruv or a shittuf on his behalf without his consent. Intention to impede his neighbors’ ability to carry means that he states his refusal to join an eiruv or a shittuf with them.

If a courtyard that opens to two alleys made a shittuf with one of the alleys using one type of food, even if that food was entirely consumed, they may make a second shittuf and grant them a portion. They need not be informed the second time. If they have made the shittuf using two types of food and it was reduced in volume to below the necessary minimum size, they may add food to it and grant the others a share. Again, there is no need to inform them. If the food in this scenario was entirely consumed, one may make a second shittuf and grant them a share but in this case they must be informed. If the number of residents in the courtyard increases, the new residents may be granted a share in the shittuf but they must be informed.
