自签担保守行为（简称签保守行为或守行为，英语：Binding over）是普通法地区如英国和香港一种处理刑事案件的判罚，方式分为两种。

当法庭决定运行「有条件的释放」，便会要求当事人承诺，在不多于3年的期限内不触犯某些指定条件，通常是不再犯同一罪行或其它性质相近的罪行。运行方式是于当事人认罪或法庭宣判有罪后，由法庭指定担保的金额（以香港为例，不多于2,000港元）、守行为的范围及期限。违反守行为命令者要向政府缴纳该担保金。

虽然这种判罚相对之下较为轻微，但当事人仍会留有案底，丧失申请《无犯罪纪录证明书》资格。

In the law of England and Wales and in other common law jurisdictions such as Hong Kong, binding over, a binding over order, and binding over for sentence are exercises of certain powers by magistrates. A person who is bound over can be required to refrain from certain activities for a stipulated period, to be of good behaviour or to comply with other conditions. When binding a person over, the magistrate will usually stipulate a conditional financial penalty or fine to be paid if the person later breaches the binding over order. If the person breaches the conditions, he or she can be arrested and brought to court or otherwise compelled to return to court where the magistrate may impose the stipulated financial penalty or otherwise dispose of the case.
