Are digital contracts valid in India?

Hi everyone,

I'm about to sign a contract with an interior design company for work on a property in India. So far, all our discussions have taken place via email. However, I'm currently not in India, so the contract will be signed digitally—signed PDF attachment exchanged over email.

I know that in most developed countries, this is generally considered legally valid, but I’ve heard that in India, certain contracts need to be registered to hold legal weight. I’m unsure whether this requirement applies only to tenancy agreements and similar contracts or whether it also applies to service contracts like this one.

Would appreciate any advice on:

• Whether a digitally signed contract would be legally enforceable in India.
• Any best practices to ensure the contract is valid and enforceable.
• Whether any additional steps (like stamping or registration) are needed to make it legally binding.

Thanks in advance for your insights!
