通常来说，词汇的翻译要看具体语境。Good一词，在法律英语中含义十分丰富，《元照英美法词典》给出的含义如下：

有效的；法律上有充分理由的；奏效的；不可反驳的；可靠的；信誉良好的；有偿还能力的；能支付原定数额的；价格与价值相当的；到期会付款的

翻译时，要根据上下文判断合适的译法。常见的搭配有：

Good faith 诚信/善意

Good cause 充足理由

Good consideration 有效对价

Good and valid 充分有效的

Good and sufficient 充分有效的

具体使用也可参考如下双语例句：

The carrier is not entitled to invoke subparagraph 1 ( c ) of this article against a third party that has acquired a negotiable transport document or a negotiable electronic transport record in good faith, unless the contract particulars state that the goods may be carried on deck.

第三方已善意取得可转让运输单证或可转让电子运输记录的，承运人无权对其援用本条第一款第三项的规定，除非合同事项载明可以在舱面上载运货物。

To the extent that a valid reservation purports to modify the legal effect of certain provisions of the treaty, when a contracting State or a contracting organization has raised an objection to it but has not opposed the entry into force of the treaty between itself and the author of the reservation, the objecting State or organization and the author of the reservation are not bound, in their treaty relations, by the provisions of the treaty as intended to be modified by the reservation.

如果有效保留意在更改条约某些规定的法律效力，当缔约国或缔约组织反对该保留但不反对条约在它与保留方之间生效时，提出反对的缔约国或缔约组织与保留方在其条约关系中不受保留意在更改的条约规定的约束。

A declaration by a Director or the Secretary that a share has been forfeited on a specified date shall be conclusive evidence of the facts therein stated as against all persons claiming to be entitled to the share, and such declaration shall (subject to the execution of an instrument of transfer by the Company if necessary) constitute a good title to the share, and the person to whom the share is disposed of shall be registered as the holder of the share and shall not be bound to see to the application of the consideration (if any), nor shall his title to the share be affected by any irregularity in or invalidity of the proceedings in reference to the forfeiture, sale or disposal of the share.
