Legal analysis: the current law does not clearly stipulate that contracts should be signed in block letters, and the handwriting should be clear and neat.

The pen for signing the contract needs to be prepared with normal writing to avoid the existence of functional pens with faded handwriting after signing.

Legal basis: Article 490 of the Civil Code of People's Republic of China (PRC). If the parties enter into a contract in the form of a contract, the contract shall be established when the parties sign, seal or press their fingerprints. Before signing, sealing or fingerprinting, one party has fulfilled its main obligations, and the contract is established when the other party accepts it.

A contract shall be concluded in written form as stipulated by laws, administrative regulations or agreed by the parties. If the parties do not do this in writing, but one party has fulfilled its main obligations and the other party accepts it, the contract is established.
