The contract can be changed after signing, as long as both parties reach an agreement through consultation. The conditions for the validity of a change contract are as follows: the subject of the change contract is a person with corresponding civil capacity; Changing the contract is a true expression of will; Whether the change of the contract conforms to the legal provisions; Other effective conditions, etc.
What are the effective conditions of the contract?
The parties to a contract have the corresponding contracting capacity. Capacity for civil conduct is the prerequisite for the validity of civil legal acts. A civil juristic act carried out by a person with no capacity for civil conduct or a person with limited capacity for civil conduct is valid only after ratification by his legal representative. The so-called capacity for contracting behavior refers to the legal qualification of civil subjects to independently conclude contracts and obtain civil rights or assume civil obligations through their own actions. Accordingly, minors over 65,438+08 years old, or minors over 65,438+06 years old but under 65,438+08 years old, have the right to conclude contracts with their own labor income as their main source of livelihood. Intermittent mental patients have limited capacity for civil conduct and do not have capacity for contracting behavior. Mental patients who can't identify their own behavior and minors under the age of 10 are persons with no capacity for civil conduct and cannot conclude contracts. However, a person with limited capacity for civil conduct or a person without capacity for civil conduct may conclude a pure benefit contract or a contract suitable for his age and intelligence. A legal person's capacity for civil conduct can only be limited to its approved and registered production, operation and business scope. Therefore, legal persons have the ability to conclude contracts within the scope of their production, operation and business.
To sum up, the contract can be modified after signing. After the contract is signed, the parties may need to modify or supplement the contents of the contract for some reasons, such as clarifying and refining the places not clearly stipulated in the original contract, or adjusting or changing the rights and obligations of both parties according to the actual situation during the performance of the contract.
