Hello, thank you for your query.
You can refer to Avtar Singh to get information on the topics.
For some help here's a brief about the three of them:
1. Standard form of contracts: These contracts are also known as the take it or leave it contract, which means there is no scope of negotiation in such contracts. The assent on such contracts is implied by a signature. The buyer makes such a contract exempting themselves from liabilities. These contracts are the result of industrialization.
2. Government contracts: this is the same as an ordinary contract but under this contract one of the parties is the Central or the State government and in addition to the requirements of the Indian Contract Act, 1872, the provisions of Article 299 of the Constitution also has to be followed.
Hope this helps.
