I am aware that we don't give gifts -- or, more specifically, transfer ownership of an item -- on Shabbat or Yom Tov. I once asked a question about ransoming the afikoman and received this comment:

... That issue can be circumvented, I think, by having a third party accept the gifts on behalf of the intended recipients before Y"T. This is OK to do without their knowledge because "zachin le-adam shelo befanav" - "we can do unmitigated good for someone without their presence (or knowledge). – Isaac Moses Feb 20 '12

I understand that this is also done when shuls present a bar/bat mitzvah with a gift on Shabbat. And I have seen the "kinyan on another's behalf" approach used recently by somebody who I know to be careful in halacha.

My question is about the logistics: if one wants to effect such a transfer using an agent to accept in advance on another's behalf, what must one do? Specifically:

  • Are there any restriction on who the agent can be?

  • Is there any specific declaration text that either the giver or the agent needs to say, or is anything that gets the idea across ("I am giving this to Ploni"/"I accept on Ploni's behalf") ok?

  • Can this be done for an unnamed person that can be identified later, such as "the child who presents me with the afikoman"?

  • Can this be done for unnamed people who aren't identified in advance, such as "any guests I have for Shabbat lunch" (maybe you made up something in advance, like bentchers or something to commemorate a simcha)?

DoubleAA linked this page from Hebrew Wikipedia in chat; possibly there are answers to be found within, but I can't read it.

    Shoot! I wanted to ask this question; it came up last week. IAE, you asked a much more detailed question than I would have, so +1 :)

    @Shokhet I just saw it, so it was fresh in my mind. And I could have just asked the person who did it, but it would be better for the Googleverse for the question to be here. :-) Dec 15, 2014 at 17:18
  • I don't think one can appoint themselves (or be appointed by someone other than the intended recipient) as Shali'ach to receive on behalf of the intended recipient. The only way I see this working in the cases you mention, is if the parent is automatically considered a Shali'ach for their offspring (which I'm not sure the parent would be), even without being formally appointed by the latter. (I have no source to back me up, so this is only a comment.)

  • The person who did it exercises this practice mimetically and can't cite any sources or specify any criteria authoritatively without doing a bunch of research. BTW, wouldn't you say that halacha applies, since at least some of your questions are asking about the requirements and not just implementation tips?

See here for a general overview and various opinions on giving gifts on Shabbos.

.. the Beis Yosef (OC 527) allows one to give a gift on Shabbos if it will be used for Mitzva purposes. This is the basis for allowing one to give their Lulav and Esrog to another as a gift on the first day (or 2) of Sukkos.

The Magen Avraham (OC 306:15) question the practice of giving presents to a Chassan who delivers a speech on Shabbos. The Chasam Sofer, (Hagaos Hachasam Sofer OC 306), however disagrees as such a gift serves a Mitzva purpose by giving true kavod to the Torah. The Aruch Hashulchan extends this , allowing one to give wedding presents at the Shabbos Sheva Brachos, as doing so brings Simcha to the Chassan and Kalla; itself a great Mitzva.

Likewise, R’ Ovadia Yosef (Yechave Daas 3:21) allows giving Bar Mitzva presents on Shabbos (especially Seforim that may be used that day) as they can serve to encourage the boy in his Torah learning and religious lifestyle.

The Shemiras Shabbos Kehilchasa (29:29) writes that one who wants to give a gift on Shabbos should give it over to him via a proxy before Shabbos. The proxy acquires it on behalf of the receiver.

As we can't trust children to properly give something back (See Kiddushin 19a; Shulchan Aruch 658:6), the proxy needs to be a adult (man or woman).

There is no specific formula, though the proxy should understand the role that they are serving.

One cannot perform this in the case of 'whoever finds the afikoman' as it is considered something that does not yet exist (Davar Shelo Ba L'Olam). Being that we typically understand that what dependent children own technically belongs to their parents, it wouldn't be an issue for their parents to give their younger children a gift on Shabbos or Yom Tov.

Likewise, it can't be done for unnamed guests, though it may be permissible as it is for mitzva use..

    Why is Davar Shelo Ba L'Olam? The recipient exists already (s/he was born!) Do you mean to say it's Bereirah?

  • I don't know why the proxy needs to be able to "give something back"? What is s/he giving back??

  • my point is that children can't be appointed to do a kinyan on someone's behalf, because while they can receive, they can't give.

  • Where is the child giving in this case?

  • Perhaps he's acquiring it on behalf of the one receiving it - therefore he needs to be able to give it over..

In short: I want to gift a [whatever] to my friend Yonah (gender-neutral) on Shabbat. So before Shabbat, I go to my friend Simcha (gender-neutral, but over the age of bar/bat mitzva) and say: "I would like you to acquire this on behalf of Yonah." I hand it to Simcha, and Simcha picks up the [whatever] a few inches in demonstration of acknowledgment. The [whatever] now belongs to Yonah.

This is also, by the way, how you put a "real" eruv into effect. After you put the string-and-posts around your neighborhood, converting it into one big courtyard, you need to designate some shared food that's available for all the residents. So the rabbi takes a box of matza (it's convenient and nonperishable) and hands it to -- the eruv chairman, the shul president, whoever -- "please acquire this on behalf of everyone in this area."

    Can Simcha be related to you? Do you need 1 tefach of 3 tefachim for the prohibition of gifts on Shabbat?

  • Couldn't you designate the food before the mechitzot are up?

  • Would you be able to edit in a source for the procedure you describe? (And are there any limitations on who can be the agent beyond age?) Dec 28, 2014 at 3:02
