Counterpart

A counterpart is one of several identical copies of a contract, each signed by one or more of the parties, that together make up a single binding agreement. Signing in counterparts lets people who are not in the same room execute a contract without passing one piece of paper around. Contracts often include a counterparts clause stating exactly this.

The clause usually reads along the lines of: this agreement may be executed in any number of counterparts, each of which is an original, and all of which together form one instrument. In practice, party A signs their copy, party B signs theirs, and the signature pages are exchanged. Many modern clauses also confirm that electronic signatures and scanned or PDF copies count as valid counterparts.

Imagine two co-founders and an investor signing a shareholder agreement. The investor is travelling, one founder is in Berlin, and the other in Austin. Each signs the same final version separately, and the lawyer collates the three signature pages into one completed set. Everyone ends up bound by one agreement, even though no single page carries all three signatures.

A common misconception is that counterparts are different versions of a contract. They must be identical in their terms; if the copies differ, you may have a dispute about which terms were agreed, or no agreement at all. Another is that counterparts only matter for paper. They are equally relevant for electronic workflows, particularly when parties use different signing tools. Rules for certain documents, such as deeds in some jurisdictions, can be stricter, so check before relying on counterparts for those.

With a single e-signature envelope, counterparts often become unnecessary: all parties sign the same file, and the document hash and audit trail show that everyone signed exactly the same version. That avoids the classic problem of collating signature pages from slightly different drafts, which is one of the more common sources of avoidable post-signing disputes.

Our take: counterpart clauses are good drafting and cost nothing to include. But if you control the signing process, getting everyone onto one electronic document is cleaner than juggling separately signed copies and hoping they match.

In eSignSimple, all signers sign the same PDF, in sequence or in parallel. The final file carries every signature, the certificate of completion lists each signer, and a SHA-256 hash lets anyone confirm through our /verify page that the version they hold is the one everyone signed.
