Copyholds are transferred by a surrender of the land to the lord and an admittance by him of the new tenant. The surrender and admittance take place in the lord's court (a); the tenant hands a rod (representing a twig from the land) (b) to the steward, and the steward hands the rod to the new tenant, to whom he is said to grant "seisin of the rod."
The land can be surrendered "to the use of" another person, or the copyholder can covenant that he will surrender it to another. This passes an equitable estate in the copyhold, but the legal estate cannot be acquired without admittance.
Customary freeholds are usually transferred by an ordinary deed, and not by surrender and admittance.
