The validity of the unauthorized disposition contract in the civil code is: the disposition right is invalid without ratification, but effective after ratification. If the party concerned fails to urge the counterpart, the exercise of right of ratification is not limited by time, and the person who has been ratified will take the initiative to express his intention of ratification or not.

For those who have no right to dispose of other people's property, it is an invalid civil act, which is likely to constitute an infringement of other people's property and should bear corresponding legal responsibilities. However, under special circumstances, if the law stipulates that the person without the right to dispose has the right to dispose after ratification by the obligee or the person without the right to dispose has signed a contract, the contract concluded by such disposition is valid.

General legal effect of unauthorized disposition:

1. If it has no right to dispose of it, the obligee will not ratify it. If the punishment is not delivered and the buyer fails to pay the price, the sales contract or gift contract is invalid. If the buyer or the donee is in good faith, the person who has no right to dispose of it shall be liable for damages.

2. Without the right of disposition, the obligee refuses to ratify. At the time of disposition and delivery, the gift contract is invalid. Under the framework that China's laws do not recognize the independence and ineffectiveness of real right acts, the ownership of disposition belongs to the obligee; However, in the case of a sales contract, when the buyer fails to pay the price and acts in good faith, the right of disposition does not belong to the obligee, but to the buyer. The losses suffered by the obligee can only be made up by the following ways: the disposer claims the return of unjust enrichment from the buyer, and cannot ask the buyer to pay the price because the sales contract is invalid according to the regulations.

3. If there is no right of disposition, the obligee refuses to ratify. When the disposal has been delivered and the buyer has paid the price, the buyer obtains the ownership of the disposal in good faith, and the obligee can only claim unjust enrichment from the disposer. In this way, when he still has losses, he will claim damages from the disposer based on tort law. The tort here is also a general tort, and the burden of proof of the obligee is heavy.
