Whether it is necessary to pay the maintenance fund before repossession shall be subject to the contract agreed by both parties at that time. When the developer delivers the house, the purchaser is required to pay the deed tax and the maintenance fund before taking the key, which depends on the agreement between the purchaser and the developer in the commercial housing sales contract. If the contract between the two parties clearly stipulates that the purchaser must pay the deed tax and maintenance fund before taking the key, the purchaser should pay the deed tax and maintenance fund to the developer according to this agreement, and the developer will collect it. If there is no clear agreement in the contract that the purchaser must pay the deed tax and maintenance fund before taking the key, the developer has no right to ask the purchaser to pay the deed tax and maintenance fund first.
