Are you responsible for the guarantor of the sales contract? The answer to this question is as follows: Article 22 of this Law stipulates that during the guarantee period, if the creditor transfers the principal creditor's rights to a third party according to law, the guarantor will continue to bear the guarantee responsibility within the scope of the original guarantee. If there are other provisions in the guarantee contract, such provisions shall prevail. Article 27 A guarantor shall provide a guarantee for continuous creditor's rights in accordance with the provisions of Article 14 of this Law. If the guarantee period is not stipulated, the guarantor may notify the creditor in writing to terminate the guarantee contract at any time, but the guarantor shall be liable for the creditor's rights that occurred before notifying the creditor. Article 28 If the same creditor's right is secured by two things, the guarantor shall be liable for the creditor's right other than the things. If the creditor waives the property guarantee, the guarantor shall be exempted from the guarantee liability within the scope of the creditor's waiver of rights. You don't need a guarantor to sign a house sale contract. After all, it is very strange to find someone to guarantee when the buyer and seller are not familiar with each other.
