Parallel Signing

What is Parallel Signing?

Parallel signing is a workflow pattern where all designated signers receive the document at the same time and can complete their signatures independently, in any order. There is no dependency between signers — each person's signing action is independent of all others.

This pattern is most efficient when signers are peers or independent parties whose signatures don't depend on each other. Common examples include business partnership agreements where all partners sign independently, mutual NDAs between two companies, lease agreements where multiple tenants sign, and board resolutions where multiple directors approve.

The primary advantage of parallel signing is speed. Instead of waiting for each signer to act before the next one is notified, all signers can act simultaneously. A document requiring five signatures might be completed in hours rather than days, since the total time is determined by the slowest signer rather than the sum of all signers' response times.

Parallel signing can be combined with sequential signing in hybrid workflows. For example, a contract might require two co-founders to sign in parallel (step 1), and then be sent to the investor for countersignature (step 2). This hybrid approach captures the efficiency benefits of parallel signing while maintaining necessary sequential dependencies.
