Arbitration Agreement and Signature

*Is there any need to get arbitration agreement signed ?*

"There is no denying the legal proposition that an arbitration agreement can be inferred even from an exchange of letters, including communication through electronic means, which provide a record of the agreement. An arbitration agreement needs to be in writing though it need not be signed". - Glencore International AG v. Shree Ganesh Metals [2025] GCtR 1441 (SC)
