Frequently Asked Questions

Can I convert a unilateral NDA into a mutual NDA?

Yes, but you need to draft a new agreement or create a formal amendment. Simply adding a clause to an existing unilateral NDA may create ambiguity. It is generally cleaner to execute a new mutual NDA.

How long should an NDA last?

Most commercial NDAs protect information for 2 to 5 years from the date of disclosure. Trade secrets (like proprietary algorithms or chemical formulas) are often protected indefinitely or for as long as the information remains secret.

Is an NDA enforceable if signed electronically?

Absolutely. Electronic signatures on NDAs are fully legal and enforceable under the US ESIGN Act, state UETA laws, and the EU eIDAS regulation. DocTransfer provides compliant e-signatures with full audit trails.
