Can an ex-husband sign an electronic contract after divorce from a house sale in another province?
You can sign it electronically. According to the provisions of China's Electronic Signature Law, an electronic signature must be independent, authentic and undeniable. As long as it conforms to the legal form of electronic signature, it has the same legal effect as handwritten signature, and it can be established that the ex-husband used electronic signature when selling the house. House transactions can use electronic signatures, and attention should be paid to legal provisions and specific circumstances in actual operation.
