Donation contracts must have corresponding capacity for civil conduct, be a true expression of will, and must not violate laws or social public interests when signed. The gift contract is a unilateral contract, which is signed by the donor in a true and voluntary manner and does not violate the law, and takes effect when the recipient accepts it. Of course, if laws and administrative regulations stipulate that procedures such as examination and approval and registration take effect, those provisions shall prevail. Regarding the time limit for the performance of the gift contract, the parties shall agree on it by themselves. According to the law, a contract is a written expression of the agreed contents reached by both parties, and it has legal effect only after being signed by both parties. If only one party signs and the other party doesn't, it can't be said that both parties have reached an agreement, and the contract is not established, of course, it has no legal effect.

The features of the gift agreement are as follows:

1. A gift contract is a contract to transfer the ownership of property. In the gift contract, the donor gives the property to the donee free of charge, so that the donee can obtain the property ownership;

2. The gift contract is a free contract. Free of charge is the most prominent feature of the gift contract. The donee does not need to pay any consideration to the donor when obtaining the ownership of the gift, that is, the donee gains benefits. The donor pays the property to the donee without receiving any compensation or return from the donee.

To sum up, legally speaking, as long as the donor has the corresponding capacity for civil conduct and has the right to dispose of the donated property and give it to others voluntarily, the gift agreement will have legal effect after being signed by the donor and the donee. However, according to the law, gift is an actual civil act. Except for the gift contract or notarized gift agreement with social public welfare and moral obligations such as disaster relief and poverty alleviation, the donor has the right to cancel the gift before it is actually delivered.
