The Anglo-Norman lordships in this area were distinct in several ways: they were geographically compact and jurisdictionally separate one from another, and they had special privileges which separated them from the usual English lordships. Royal writ did not work in the Marches: Marcher lords ruled their lands by their own law—"sicut regale" ("like a king") as Gilbert, Earl of Gloucester, stated, whereas in England fief-holders were directly accountable to the king. Marcher lords could build castles, a jealously guarded and easily revoked Royal privilege in England. Marcher lords administered laws, waged war, established markets in towns, and maintained their own chanceries that kept their records (which have been completely lost). They had their own deputies, or sheriffs. Sitting in their own courts they had jurisdiction over all cases at law save high treason. "They could establish forests and forest laws, declare and wage war, establish boroughs, and grant extensive charters of liberties. They could confiscate the estates of traitors and felons, and regrant these at will. They could establish and preside over their own petty parliaments and county courts. Finally, they could claim any and every feudal due, aid, grant, and relief", although they did not mint coins. Their one insecurity, if they did not take up arms against the king, was of dying without a legitimate heir, whereupon the title reverted to the Crown in escheat. Welsh law was frequently used in the Marches in preference to English law, and there would sometimes be a dispute as to which code should be used to decide a particular case.
