第二节 意思表示
Section 2
Expression of Intent
第一百三十七条 以对话方式作出的意思表示，相对人知道其内容时生效。
Article 137
An expression of intent made through real-time communication becomes effective
from the time the person to whom the intent is expressed is aware of its
content.
以非对话方式作出的意思表示，到达相对人时生效。以非对话方式作出的采用数据电文形式的意思表示，相对人指定特定系统接收数据电文的，该数据电文进入该特定系统时生效；未指定特定系统的，相对人知道或者应当知道该数据电文进入其系统时生效。当事人对采用数据电文形式的意思表示的生效时间另有约定的，按照其约定。
An expression of intent made in a form other than real-time communication
becomes effective from the time it reaches the person to whom the intent is
expressed. Where such an expression of intent is made through an electronic data
message and the person to whom the intent is expressed has designated a specific
data-receiving system, it becomes effective from the time such a data message
enters that system; where no data-receiving system is specifically designated,
it becomes effective from the time the person to whom the intent is expressed
knows or should have known that the data message has entered the system. Where
the parties have agreed otherwise on the effective time of the expression of
intent made in the form of an electronic data message, such an agreement shall
prevail.
