The gift contract is a unilateral contract, and only one party's expression of will can be established without the confirmation of both parties. Because of this, the legal effect of the gift contract is very weak. Whether the two parties sign or not, the donor can go back on his word at any time before actually handing over the gift, that is, break the contract at any time. Therefore, it is of little significance to ponder whether there are signatures of both parties. The only valid thing is that the notarized gift contract is protected by law and does not need to be signed by both parties. So if you are a donor and you don't want to give it, don't give it. If I give it to you, you have no right to get it back. If you are the recipient and someone goes back on his word, forget it. Unless it is notarized, you should treat it as a joke.
