Legal Validity of Plain Paper Agreements
The essential conditions of a valid contract are informed consent, consideration and lawful object and such agreements are enforceable under the Indian Contract Act, 1872. Even oral agreements are valid in India, as per the act.
The Contract Act does not make stamping of agreements compulsory. It does not make an unstamped agreement/contract thereby invalid or unenforceable. Therefore, an agreement does not require mandatory stamping to make it a legal and valid instrument.
