An 'indenture' was a deed or agreement between two or more parties. Two or more copies were written out, usually on one piece of parchment or paper, and then cut in a jagged or curvy line, so that when brought together again at any time, the two edges exactly matched and showed that they were parts of one and the same original document. A 'right hand indenture' is therefore the copy of the document which was on the right hand side when the parchment was cut in two.

A 'fine' was a fee, separate from the rent, paid by the tenant or vassal to the landlord on some alteration of the tenancy, or a sum of money paid for the granting of a lease or for admission to a copyhold tenement.

A bargain and sale was an early form of conveyance often used by executors to convey land. The bargainee, or person to whom the land was bargained and sold, took possession, often referred to as becoming 'seised' of the land.
