About twenty years before the creation of the recovery rolls in 1583, the writs relating to the levying of common recoveries were hived off from the main series of Brevia files of the court to a separate series of Brevia de ingressu super disseisinam in le post, summonitione ad warrantum et habere facias seisinam files [Writs of entry, summons and seisin in the post]. After 1660, few isolated files survive.
Most of the surviving files are whole and intact, consisting of writs grouped together by law term, spiked and threaded on a long thong, and enclosed within a parchment cover inscribed with a brief content summary, which details the law term (Michaelmas, Hilary, Easter, or Trinity) plus the monarch and regnal year. For files of the Interregnum period, the cover inscription instead captures the law term and calendar year. A small number of files are lacking their covers and may be incomplete.
The records are in Latin, except between Easter 1651 and Hilary 1659/ and from Trinity 1751 onwards, when they are in English.
