Legal Translation of “appendix” and “exhibit”: annexe or pièce?

⚠️ Two terms not to be confused, depending on context

The words appendix and exhibit can be confusing, especially when they appear together in contracts, court files, or arbitration briefs. Their translation depends closely on the field: contract law, litigation, or professional correspondence.

✉️ In Correspondence: pièce jointe

In a formal letter or email, exhibit may simply mean an attachment or document enclosed with the correspondence.

📄 In Contract Law: annexe vs. appendice

In contracts, the two terms may appear together but refer to different types of documents:

• exhibit → annexe (a main contractual document)

• appendix → appendice (a supplement or sub-part of an annex)

This distinction allows for the logical organization of documents attached to the contract.

Example:

• See Exhibit A and Appendix 1 → Voir l’annexe A et l’appendice 1

⚖️ In Litigation or Arbitration: pièce produite

In contentious proceedings (court, arbitration, etc.), exhibits refers to the documents produced by the parties in support of their arguments.

Example:

• Exhibit 3 – Email from Respondent → Pièce 3 – Courriel du défendeur

In this sense, one often finds documentary exhibits, witness exhibits, and so on.

✅ In Summary

📌 TransLex’s Advice

Before translating appendix or exhibit, ask yourself three key questions:

1. Is it a contract, an exchange of correspondence, or a litigation procedure?

2. Is it a main document (annex) or a sub-document (appendix)?

3. Are we in a contentious context, with numbered exhibits?

👉 Literal translation is tempting… but can easily cause legal confusion.
