The wrong signing date of the contract does not affect the legal effect. The parties have corresponding capacity for civil rights and capacity for civil conduct, and enjoy the right to voluntarily conclude a contract according to law. The content of the contract does not violate the law, and there is no situation in which the contract is invalid as stipulated by law. The contract is legal and valid. This contract shall come into effect as of the date of signature or seal by both parties. If the date of signature is wrong, both parties should sign or seal the altered place to avoid unnecessary disputes in the future. IOUs are different from loan contracts. A loan contract is a contract in which the borrower borrows money from the lender, repays the loan at maturity and pays interest. The establishment of a loan contract (in written form) is generally concluded after both parties reach an agreement through consultation, and the contract is signed (sealed) by both parties. IOUs are mostly used for private lending. According to the folk lending habit, after the two parties reach an agreement, the borrower pays the loan to the other party and the other party immediately presents the loan to the lender under the condition of immediate performance. That is, the lender holds an iou to prove that the borrowing behavior must occur. Having a loan contract may not win the lawsuit. There is a loan contract that can be sued. However, in the course of litigation, it is necessary to provide specific evidence that can prove the authenticity and effectiveness of the loan relationship, so that the court can make corresponding judgments. If the other party refuses to perform after the judgment of the court, it will be punished accordingly. If there is a real loan relationship and the loan is not repaid on time, the creditor may bring a lawsuit to the court with relevant evidence within the limitation period. If you just signed a loan contract, but there is no fact that the loan actually occurred, such as no bank transfer receipt, no witness present, no evidence of WeChat or Alipay transfer, etc. , can't directly think that the loan has been completed. Through the above, I believe you have a certain understanding of the problem that the loan contract date is wrong and effective. If the date of signing the contract is wrongly written or altered, it will not affect the legal effect. If the contents of the contract do not violate the law, the contract is legal and valid.

Legal objectivity:

The loan contract is an important evidence to prove the relationship between creditor's rights and debts. Its contents include both parties, loan time, loan amount, loan purpose, repayment time, etc. The debtor shall perform its debt service obligations in strict accordance with the loan contract. Once the loan contract goes wrong, it will inevitably harm the interests of one party. What if the loan contract is wrong? (1) The signing of the revised loan contract must be the true intention of both parties, and the wrong loan contract is obviously not what both parties or one party wants to see. Therefore, the wrong loan contract can be changed by both parties through consultation, which is embodied in Article 77 of the Contract Law: "The parties can change the contract through consultation." Modifying the loan contract is to modify the wrong matters, so other contracts signed according to the true meaning of both parties are valid. If one or both parties want to make changes, they can also make changes after consultation. (2) The supplementary agreement is a supplement to the original contract, and the supplementary items shall be changed or supplemented by both parties through consultation. Therefore, after the wrong loan contract is written, the wrong place can be explained and corrected by supplementary agreement to ensure that the contract is legal and reasonable and more in line with the wishes of the parties.
