近日，蚌山区法院审理了一件房屋买卖合同纠纷一案，因为买房人与卖房人是朋友，卖房人收到买房人钱后，让买房人写收条，自己潇洒的在上面签了一个名，结果引来后患无穷。

李山与王军是多年的好朋友，王军近日想将其所有的一套房屋出售，李山得知后便同王军联系。王军的房屋因为没有办理产权证、土地证，手头又很紧，王军向李山提出先从李山处拿5万元用于办理证件，办好后，再具体谈买房事宜，于是，李山给了王军5万元，因为王军字写的不好，就让李山写了一张收条，写明“今收到李山现金5万元整（50000）”，王军在落款处签了自己的名字。事后，双方口头约定了房屋价格等事项，在办理过户过程中遇到困难，致使暂时无法办理过户手续，何时能办理还遥遥无期，李山要求解除合同，让王军立即退款，王军已把钱花的差不多了，一时又拿不出这么多钱，双方因此发生纠纷，李山经常喝过酒后找王军闹，王军无奈之下避而不见，李山一气之下，将王军诉讼来院，要求解除房屋买卖合同，双倍返还购房定金。                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                                     

王军收到诉状后，一头雾水，怎么出来个双倍返还定金呢？来到法院一看，收条“今收到李山现金5万元整（50000）”紧接“（50000）”后，多了“购房定金”四个字，李山说写收条时就讲定这5万元是购房定金，王军则说当时没有讲是购房定金，只是购房款，也没有“购房定金”四个字，这四个字是后加的，双方发生激烈争吵。因为整个收条都是李山书写的，是同时书写还是后加的，难以界定，即使通过鉴定也很难明辨是非，使整个案件陷入僵局。

最终，经过多次调解，本案以王军赔偿李山一万元经济损失调解结案，但仍给了王军一个沉痛教训，再三表示当时如果自己写收条，或在“（50000）”后紧接着签名，就不会有这么多麻烦。明白了在出具法律意义的文书时，一定要明确、清楚，当时多写几个字，多些细心，事后会省去很多纠纷与麻烦。（文中人物系化名）
