Quantum Meruit:
Quantum meruit is a Latin phrase meaning "what one has earned". In the context of contract law, it means a reasonable sum of money to be paid for services rendered or work done when the amount due is not stipulated in a legally enforceable contract.

Quarter Section:
In real estate, a quarter or quarter section is a geographic reference for a parcel of land measuring one-fourth of a square mile, or 160 acres (0.65 km2 or 64.7 hectares). It was a common size of a tract under the Dominion Land Survey in Canada and Homestead Acts in the United States.

Quiet Enjoyment:
A covenant that promises that the tenant or grantee of an estate in real property will be able to possess the premises in peace and without disturbance.

Quiet enjoyment also includes the right to basic services such as heat and hot water, the right to exclude others from the premises, the right to peace and quiet, the right to clean premises, and for high-rise buildings, elevator service. In many respects the implied covenant of quiet enjoyment is similar to an Implied Warranty which warrants that the landlord will keep the leased premises in good repair.

Quit Claim Deed:
A quit claim deed is a legal instrument by which the owner of a piece of real property, called the grantor, transfers all claims or rights to a recipient, called the grantee. The owner/grantor terminates (“quits”) any interest and claim to the property, thereby allowing claim to transfer to the recipient/grantee.

A quit claim deed contains no title covenant and thus, offers the grantee no warranty as to the status of the property title; the grantee is entitled only to whatever interest the grantor actually possesses at the time the transfer occurs.
