闲鱼小法庭多久出结果？3分钟了解小法庭的所有知识点！「2」

上期闲鱼小法庭知识快捷入口：闲鱼小法庭多久出结果？3分钟了解小法庭的所有知识点！「1」今天接着来介绍闲鱼小法庭，知己知彼百战百胜！有些没有经历过闲鱼小法庭的小伙伴，会问：闲鱼小法庭怎么申请？你没有看错，相当一部分人甚至还没有经历过闲鱼小法庭。那么怎么申请呢？在卖家拒绝买家的退款申请后，买家可进入退款详情页面，点击申请介入，此时系统会根据您的维权场景确定由人工维权小闲鱼来处理还是通过17个大众评审处理。如符合闲鱼小法庭场景，会在申请介入时提示纠纷问题将会进入闲鱼小法庭中进行判决，并不能自己选择由谁介入~还有一个很搞笑的问题：闲鱼小法庭明明判了退货，却没有退货地址，怎么办？小法庭判定后，系统会给予卖家24小时的时间确认自己的退货地址，哈尼不要着急，如卖家超时未配合提供，系统将提供给您卖家的默认退货地址，若卖家在退款或是闲鱼私信您新的地址，您可以按照新的地址退货哦~简单说，就是卖家不提供，那么就用默认的地址，提供了，就用新的地址，不用着急。小法庭介入后，为什么可以撤销？闲鱼小法庭是来搞笑的？在确认收货时间到达之前，买家是可以撤销重提的哦，当然您放心，我们不会无限制地让买家撤销退款的。这边也建议您关注，若买家撤销了退款，在默认确认收货时间到达时买家未再重提，您的交易是会默认达成的，会支持打款给您的呢。其实闲鱼小法庭有很多的问题，但是总能解决的，有问题也欢迎大家在我们的交流群留言，互相交流！...
