Be sure to write by hand. When signing a contract, you need to write by hand. If you don't write by hand, the contract can't have legal effect. If you want to be more standardized, in addition to handwriting, you need to press your own handprint on the contract.

Article 490 of the Civil Code: If the parties conclude a contract in the form of a contract, the contract is 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.
