The purchase contract should describe the wallbox condition at handover, not only name the parking space. Relevant details include manufacturer, model, serial number, charging capacity, accessories, keys or cards, known faults, maintenance records and whether a user account is transferred.
The seller should disclose the basis on which the installation was made, any conditions and any planned joint or technical alteration. The article on condominium agreements and house rules provides a broader contract-review complement.
If the wallbox is to be removed, the contract should state the deadline, cost allocation, removal of equipment and cables, restoration and delivery of a usable parking space. If it transfers, warranties, retention or a precise condition record should refer to the identified installation.
