Another common example is the English practice of "peppercorn rent", the nominal rental sum for property, land or buildings. Where a rental contract is put in place and the owner of the property wishes it to be rent-free, it is normal to charge a small sum as "peppercorn rent", because if the owner wants to lease the property, he must charge some rent so that consideration exists for both parties. Furthermore, a peppercorn rent is often used as a form of nominal ground rent where a (potentially substantial) premium has also been paid on commencement of a long lease of, say, 99 or 125 years (a "virtual freehold"). The notional collection of the annual peppercorn rent helps to maintain a formal landlord–tenant relationship between the two parties, precluding the risk of a claim for adverse possession from the tenant arising, were no consideration to be paid for an extended period.
