Definition
A writ in historical English law that protected a person who had received land from a disseisor — that is, someone who had wrongfully dispossessed the true owner. The writ shielded the alienee (the one who received the land) from being pursued in an assize for damages, provided the original disseisor had sufficient assets to satisfy any judgment against him. In other words, where the wrongdoer himself could make the injured party whole, the law did not require the innocent recipient of the land to answer for damages in the assize proceeding.
Why It Matters in Research
Erandis is a rare writ with no modern counterpart and no continuing legal significance. Researchers will encounter it almost exclusively in antiquarian sources, early English register materials, or historical surveys of the assize system. Its sole documentary anchor in the Law Mind corpus is the Registrum Originale (Reg. Orig.), the historical collection of original writ forms used in English common law courts — the citation in Black's (Reg. Orig. 214) is the controlling reference and should be treated as definitive for this term.
The practical research trap here is terminological: erandis sits within a dense cluster of disseisin-era writs, and its function is easy to confuse with related remedies unless the researcher keeps the specific protecting purpose in view. It does not restore land, it does not determine title, and it does not operate against the disseisor — it insulates the alienee from a damage award in an assize of novel disseisin when the disseisor remains solvent. Researchers tracing the development of English real property remedies or the mechanics of disseisin should note that this writ reflects an early equitable instinct within the common law: protecting an innocent transferee from bearing the cost of another's wrong where the actual wrongdoer can pay.
Because this writ belongs to the era of the original writs system — largely displaced by the Statute of Uses (1536) and the gradual erosion of the real actions — any secondary source postdating the seventeenth century is unlikely to address it with precision. Researchers should work directly from the Registrum Originale and from early commentaries on the assize system.
Historical Dictionary Support
Black's Law Dictionary (2nd Ed.) provides the only substantive dictionary entry for erandis in the Law Mind corpus. The definition is brief but precise: the writ ran in favor of the alienee of a disseisor and protected that person from being molested in assize for damages, contingent on the disseisor having sufficient assets to cover them. Black's correctly anchors the entry to Reg. Orig. 214.
No competing or supplementary definition exists in the corpus. The absence of the term from other historical law dictionaries reflects how specialized and archaic the writ was even by the time major legal dictionaries were being compiled. Researchers should not read its absence elsewhere as evidence of doubt about the definition Black's supplies — it is simply a term that fell out of practical use early and was never widely glossed.
Jurisdictional Note
Erandis was an English common law writ with no known reception in American, Scottish, or other common law jurisdictions. It belongs entirely to the historical English writ system and has no operative significance in any modern jurisdiction.
