律师函书写有效的技巧：
一、要点记录
1、明确客户的诉求和目标：第一步是明确客户的诉求和目标，并尽量精确地描述客户的情况。
2、清晰表达事件背景：其次，要清晰地描述事件背景，如发生时间、发生地点、主要参与者和事件本身，尽量使用具体的语言表达，避免笼统的描述。
3、分析案件实质：同时，要深入分析案件实质，对双方的责任进行清晰的把握，根据事实和法律来评估案件的可能结果，为客户提供有针对性的建议。
4、参考法律依据：此外，要参照合适的法律依据，如适用的法律条文、法律解释等，以便给予证据支持和理论依据，提高函书的有效性。
二、结构组织
1、开头部分：一般函书的开头部分，要写明编写人的身份、、函书的收件人，以及函书的主题内容等信息。
2、正文部分：接下来就要开始写正文部分了，要根据上述要点，有条理地描述案件的背景、案件实质、适用的法律依据、以及分析案件可能结果等。
3、结尾部分：最后，要简单总结函书的主要内容，并谨记有助于提高律师函书有效性的重要原则：简明扼要、具体清楚、有助于支持客户的立场。
委托书律师函附应包括下列内容：
1. 开头：要用简单明了的话清楚地表达出你的诉求，以及你想要什么样的结果。
2. 陈述：在陈述部分，要详细地阐述你的权益受到了侵害，并且提供有力的事实和证据来支持你的主张。
3. 论证：在论证部分，需要引用有关法律条文，以及法院对这类案件作出的先前裁决，以证明你的主张有理有据。
4. 结尾：在结尾部分，要简洁、明确地表达出你要求的结果，并提供一些可能的解决方案。
委托书律师函附注意事项：
一、定义：
律师函是指律师以书面形式向另一方提出要求、建议或声明意愿的函件。
二、有效性：
1、委托人名字出错律师函有效吗答：如果委托人名字出错，律师函并不一定就无效，这取决于具体情况。例如，律师函中的委托人名字出错，但与受托人名字正确，此时受托人可以确认函件确实来自于该委托人，则律师函仍然有效。
2、怎么写律师函答：律师函应该包含以下要素：
（1）发函方的信息，包括委托人的姓名、地址、等；
（2）收函方的信息，包括受托人的姓名、地址、等；
（3）清楚表明律师函的主题，包括主要内容、提出要求、建议或声明意愿等；
