Contra proferentem是拉丁语，翻译为英文是“against the offeror”，直译即指不利于提供者。在合同中，常指对协议起草人不利解释之原则。元照英美法词典中对其的解释如下：用于书面文件的解释，意为文件中的模棱两可之处应作最不利于文件起草者或文件提供者的解释。Contra proferentem is a rule of contract interpretation that states an ambiguous contract term should be construed against the drafter of the contract. The term contra proferentem is derived from a Latin phrase meaning “against the offeror.” 作为合同解释原则之一，很多合同都会纳入这一内容。这一内容有时以contra proferentem的形式出现，有时以no construction against drafter的形式出现。以下为部分双语条款，供参考：

示例一：

Contra Proferentem. Each and every provision of this Agreement shall be construed as though parties participated equally in the drafting of same, and any rule of construction that a document be construed against the drafting party, including without limitation the doctrine commonly known as contra proferentem, shall not be applicable to this Agreement.

不利解释。本协议各条款应被解释为如同双方共同同等参与协议各条款的起草一般。任何关于文件应作不利于文件起草方的解释原则，包括但不限于不利解释原则，均不适用于本协议。

示例二：

No Construction Against Drafter. The Parties acknowledge that this Agreement and all the terms and conditions contained herein have been fully reviewed and negotiated by the Parties. Having acknowledged the foregoing, the Parties agree that any principle of construction or rule of law that provides that, in the event of any inconsistency or ambiguity, an agreement shall be construed against the drafter of the agreement shall have no application to the terms and conditions of this Agreement.

不对起草方作不利解释。双方确认，本协议及本协议所有条款和条件已由双方充分审核及商讨。在确认前述事实的前提下，双方同意任何作出如下规定的解释原则或法律规则均不适用于本协议的条款和条件：如果协议存在任何不一致或模糊之处，协议应作出不利于起草方的解释。

示例三：

No Construction Against Drafter. No provision of this Agreement or any related document will be construed against or interpreted to the disadvantage of any party hereto by any court or other governmental or judicial authority by reason of such party having or being deemed to have structured or drafted such provision.

不对起草方作不利解释。任何法院或其他政府或司法机关均不会因本协议或任何相关文件的一方安排编制或起草或被视为安排编制或起草本协议或任何相关文件的任何规定而在解释或解读该等规定时作出不利于该方的解释或解读。

示例四：

Contra Proferentem. The Parties acknowledge that they and their respective legal counsel have reviewed and participated in negotiating and settling the terms of this Agreement and agree that the contra proferentem principle of construction, set out at article 1432 of the Civil Code of Québec, or any similar rule or principle, shall not be applied in interpreting this Agreement, including without limitation to resolve any ambiguity in this Agreement.

不利解释。双方确认，其及其各自的法律顾问已对本协议条款进行了审核，并已参与商讨和达成本协议各项条款，并同意《魁北克民法典》第1432条规定的不利解释原则以及任何类似法规或原则在解释本协议时不得适用，包括但不限于解决本协议中的任何模糊之处。
