A lease was a contract in which one person granted to another the right to exclusive possession of their land for a period, in return for rent.
From 2369, the lease on Quark's Bar was held by the Federation, but they did not charge Quark any rent, nor did they ask him to reimburse them for the cost of maintenance or the drain on the station's power supply. During the strike organized by Rom's Guild of Restaurant and Casino Employees in 2372, Captain Benjamin Sisko threatened to bill Quark for five years' worth of these outstanding charges unless he agreed to negotiate an agreement with his brother.

In Ferengi culture, pregnancy was considered a rental, and as such, the lessee had the right to have a say in what the woman carrying the offspring did while expecting. Quark mentioned this in 2373 when Miles O'Brien expressed concerns over Kira Nerys's caffeine habit while she was carrying his son. (DS9: "Nor the Battle to the Strong")
