Conclusion: In housing sales disputes, evidence can be collected from contracts, payment vouchers, communication records, housing status evidence, witness testimony and other aspects, and the authenticity, legality and relevance of evidence should be ensured to safeguard rights and interests. Legal analysis: Different types of evidence play different roles in housing sales disputes. As the core evidence, the housing sales contract defines the rights and obligations of both parties. The supplementary agreement, subscription letter and other relevant documents are further supplements to the contract. It is vital to keep these originals. The payment voucher can intuitively prove the payment of house purchase funds, and ensure the clear flow of transaction funds. The communication record can restore the details of negotiation in the transaction process and provide powerful clues for dispute resolution. The evidence of housing condition can prove the actual condition and ownership of the house, which is of great significance for judging the responsibility and rights. The testimony of the witness can be used as evidence to enhance the credibility of the evidence. According to the Civil Procedure Law of the People's Republic of China, evidence must be verified before it can be used as the basis for determining facts. Therefore, it is critical to ensure its authenticity, legitimacy and relevance when collecting evidence, so as to better safeguard their own rights and interests in dispute resolution. If you encounter disputes or have questions about the collection of evidence in the housing sale, you are welcome to consult a professional legal person.
