First in point of time and interest comes the mortgage debt, i.e. the claim for the return of money lent on the security of some tangible object. Such claims are among the earliest fruits of a commercial civilization, and are nearly always affected the same way, viz. by the deposit or pledge of the security with the creditor, to be redeemed or returned on the payment of the debt.

The Lease and Release, attributed to Serjeant Moore, was based on the fact that the Statute of Inrolments did not apply to terms of years.

It was natural that the direct wielders of the royal prerogative, men who sat in the Star Chamber and the Privy Council, who knew the secrets of the State and the necessity for prompt action, should despise the merely declaratory character of a good deal of Common Law process.
