Maintenance fund, also known as "public maintenance fund" and "special maintenance fund", refers to the fund that the owners of residential properties pay a certain amount of money to a special account for the maintenance of public facilities and equipment in the property area, and authorize the owners' committee to manage and use it uniformly. The maintenance fund is raised by the owners of the property, who enjoy the ownership of the maintenance fund according to the proportion of payment, but the right to use it belongs to all owners, and individual owners may not withdraw all their own maintenance funds from the bank.
