Generally speaking, a contract is valid if its structure and content comply with the law and both parties sign it on the basis of equality and voluntariness.

Whether your confidentiality agreement is valid or not needs to be judged in many ways. And the confidentiality agreement is just a clause, is it attached to the contract?

All the above issues will involve different legal issues and affect the legal effect of the agreement.

The following is some introduction of the contract, I hope it will help you! Hope to adopt!

1. A contract is an agreement between the parties or both parties to establish, change or terminate a civil relationship.

2. A contract, also called a contract or an agreement, is an agreement between equal parties to establish, change and terminate the relationship of civil rights and obligations. As a civil legal act, a contract is the product of the parties' agreement, and it is an agreement expressed by more than two parties. A contract is legally binding only when the meaning expressed by the parties is legal. A legally established contract shall take effect from the date of its establishment and be legally binding.

3. The difference with the agreement:

A mutually agreed contract. Simply put, you love me, and then we fix what we all agree on, make it clear, make it clear, and then what we agree on is an agreement, which is legally called a contract.

Generally speaking, valid contracts and agreements have the same legal effect, unless they are invalid or become invalid due to certain conditions. For example, if one party to a contract or agreement is a 7-year-old child, such a contract has no effect.

A contract or agreement that needs notarization only fixes and strengthens the effectiveness of the contract or agreement. If the law does not require it, and the parties to the contract or agreement have not agreed, there is no need for special notarization. Generally, two contracts or agreements are enough. Each party holds one copy of this contract. If there is a third copy, it is likely to be given to a witness or a third party. This role is also to strengthen the effectiveness of the contract or agreement, which is agreed by both parties.

Contracts or agreements generally differ only in name and title. As long as it does not violate laws and moral habits, the parties can arbitrarily agree on the name, content and form of the contract or agreement, which are all valid.
