Seal

An impression on wax or wafer or other tenacious and impressible substance attached to a writing by way of execution; the substance so impressed; the instrument with which the impression is made; any device which the law permits as a substitute. At common law nothing less than such substance so impressed is a seal, — an impression in the paper or parchment on which the writing is made is not enough; but in many of the states the ancient rule is modified, in some a wafer or wax unimpressed being sufi Bcient, and in others a mere scroll or flourish of the pen.

In English law

The sitting of a court
