paying the maintenance fund will not take away the purchase contract. Because the maintenance fund usually refers to the residential special maintenance fund. Residential special maintenance funds refer to the funds earmarked for the maintenance, renewal and transformation of residential parts and facilities after the warranty period expires, and shall not be used for other purposes. According to the local measures for the management of special housing maintenance funds, the claimant should bring the original purchase contract when paying the maintenance fund, and the original ID card of the purchaser should go through the deposit formalities at the maintenance fund window. The original purchase contract is only used as a photo archive and will not be taken away.
