I have seen the corresponding case before:
On 20 16, Wang bought glass materials from Zhang, and showed Zhang a debit note, which said, "I owe the witness 30,000 yuan for glass." After repeated urging, Zhang sued the court. Wang argued that Zhang's prosecution was wrong, and his real name was Wang Qingbing, not. He refused to admit the arrears and submitted Wang Qingbing's household registration information to the court. However, the proof materials of the village committee and the testimony of the witness Wu Mou confirmed that Wang Qingbing (also known as Wang Gang) was the same person. After the court explained that Wang did not apply for handwriting identification of the debtor's name in the debt, his behavior was regarded as that he did not provide evidence to prove his claim and should bear the adverse consequences of proof. Accordingly, Wang Qingbing should bear the responsibility of repayment.
The judge said that in practice, especially in rural areas, in addition to the household registration name, there are many forms of signature, such as aliases, former names, nicknames and so on. The law should respect the parties' expression of will. In practice, as long as the identity of the actor can be determined, its legal effect should be recognized. In this case, although the debtor's name in the IOU presented by Wang was wrong, the creditor provided other evidence to prove that there was a creditor-debtor relationship between the two parties, and the debtor failed to provide evidence to prove his claim, so it was determined that his non-household registration signature had the same effect as the official name.
