同事刘某因买房向我借了2万元,约定1年后还,但没有写借据,也没有其他人在场,只有一位同事李某听我说过这件事。事隔2年多,刘某拒不还钱,称其2万元早已偿还。我想去法院告他,他却说到了法院还是这句话。李某说他愿意出庭说明他听我说过刘某找我借钱一事,但听说应当在2年内起诉,? Colleague Liu bought a house because I borrowed 20,000 yuan, agreed 1 year later, but did not write any evidence, no other people present, only one colleague Lee heard me say this. After more than two years, Ryu refused to repay the money, saying that 20,000 yuan already repay. I want to go to the court to sue him, but he said the court still said these words. Lee said he was willing to appear in court that he heard me talk about Liu find me to borrow money, but I heard that prosecution should be within 2 years?
