在法律文件中，"by hand"偶尔会出现，尤其是在协议当中。出现在协议合同中时，除了其常见含义，或可根据文意取下列含义，“由专人（送达通知信函等）”或“签字”。下面来看具体实例

1例句

A notice given in accordance with the provisions of this Agreement shall be deemed to have been delivered if delivered by hand, upon being signed and received by the recipient

参考译文：

根据本协议的规定发出的通知，如果由专人送达，则接收人签收后即被视为已经送达。

2实例

Any shareholder can transfer all or any his shares by an instrument of transfer in the usual or common form or in a form prescribed by the Designated Stock Exchange or in any other form approved by the Board and may be under hand or, if the transferor or transferee is a clearing house or its nominee(s), by hand or by machine imprinted signature or by such other manner of execution as the Board may approve from time to time.

参考译文：

任何股东可以一般或通用的格式、或者指定证券交易所规定的格式、或者董事会批准的任何其他格式的转让文书转让其全部或任何股份，该等文书可以亲笔签署，或者如转让人或承让人为结算所或其代理人，则可以亲笔签署或机印方式签署或以董事会不时批准的其他方式签署。
