Henry was determined to protect lawful seisin of land and issued assizes giving the Royal Court authority to decide land law issues which had not been given justice in the county or lord's court. But he did not ordain that all litigation respecting free tenements, e.g. right of seisin, should take place in the king's court. Rather he gave protection to mere possession of land, which could be justified because possession was intimately associated with the maintenance of the king's peace. These assizes included issues of novel disseisin [recent ejectment] of a person's free tenement or of his common of pasture which belonged to his freehold. By the assize of novel disseisin, an ejected possessor could have a jury of recognitors decide whether the ejectment had been just or not. Though the petty assize of disseisin only provided a swift preliminary action to protect possession pending the lengthy and involved grand assize on the issue of which party had the more just claim or ultimate right of seisin, the latter action was only infrequently invoked. The temptation of a strong man to seize a neighbor's land to reap its profits for a long time until the neighbor could prove and enforce his right was deterred. Any such claim of recent dispossession [novel disseisin] had to be made within three years of the disseisin.
An example of a writ of novel disseisin is: The king to the sheriff, greeting. N has complained to me that R unjustly and without a judgment has disseised him of his free tenement in [Houndsditch] since my last voyage to Normandy. Therefore I command you that, if N gives you security for prosecuting his claim, you are to see that the chattels which were taken from the tenement are restored to it, and that the tenement and the chattels remain in peace until Sunday after Easter. And meanwhile you are to see that the tenement is viewed by twelve free and lawful men of the neighborhood, and their names endorsed on this writ. And summon them by good summoners to be before me or my justices on the Sunday after Easter, ready to make the recognition. And summon R. or his bailiff if he himself cannot be found, on the security of gage [something given as secuxrity for performance] and reliable securities to be there then to hear the recognition. And have there the summoners, and this writ and the names of the sureties. Witness etc.
Then an assize panel of recognition summoned concurrently with the defendant and before he had pleaded, viewed the land in question and answered, from their knowledge, these questions of fact: 1) Was the plaintiff disseised of the freehold in question, unjustly and without judgment? 2) Did the defendant commit the disseisin? Testimony of a warrantor (or an attorney sent by him in his place) or a charter of warranty served to prove seisin by gift, sale, or exchange. No pleadings were necessary and the action could proceed and judgment given even without the presence of the defendant. The justices amerced the losing party with a monetary penalty. A successful plaintiff might be awarded damages to compensate for the loss of revenue.
There was also a writ for issues of inheritance of land called "mort d'ancestor". By the assize of mort d'ancestor, an heir of a tenant who died and who was refused the land by the lord could have this refusal determined to be just or unjust. For this issue, the Royal Court used an similar assize panel of twelve men to decide whether the ancestor was seised as of fee in his demesne, if the plaintiff was the nearest heir, and whether the ancestor had died, gone on a crusade but not returned, or had become a monk. Then it could give possession to the heir. Since about 1150, heiresses divided the land of their father if there was no son. The widow, of course, retained her dower rights. As of 1176, the widow held her dower from the heir instead of from the husband's lord. If the heir was a minor, the guardian lord would be in actual control of the land. A national policy was implemented that in the case of the death of a freeholder, the rights of the family, his will, and his debts were to be provided for before relief was paid to his lord.
Eventually royal justices acquired authority to decide the ultimate question of right to land using the grand assize as an alternative to the traditional procedures which ended in trial by combat. Issues of the ultimate right of seisin were brought to the Royal Court by a contestant in a local court who "put himself [or herself] upon the King's grand assize". The assize consisted of twelve knights from the county or neighborhood who were elected by four knights of the same county or neighborhood (selected by the sheriff or the suitors) and who were known as truthful men and were likely to possess knowledge of the facts, either from personal seeing or hearing, or from statements which their fathers had made to them from their personal knowledge. The avenue by which a person who felt he had not had justice in the manor court on his claim for certain freehold land appealed to the king was by writ of right after the manor court's decision or by a writ praecipe during the manor court's proceeding. An example of a writ praecipe is: "The king to the sheriff greeting. Command [praecipe] N. to render to R. justly and without delay one hide of land in a certain vill, which the said R. complains that the aforesaid N. is withholding from him. If he does not do so, summon him by good summoners to be before me or my justices on the day after the octaves of Easter, to show why he has not done so. And have the summoners and this writ. Witness." When the parties appeared in court, the claimant states his suit such as: "I claim against this N. the fee of half a knight and two carucates of land in a certain vill as my right and my inheritance, of which my father (or grandfather) was seized in his demesne as of fee in the time of King Henry the First, and from which he took the profits to the value of five shillings at least, in grain and hay and other profits; and this I am ready to prove by this freeman of mine, H., and if any evil befalls him them by this other man or by this third man, who saw and heard it". Then the defendant chose to deny the claim word for word with proof by combat or to put himself upon the grand assize of the king. If he chose trial by combat, the parties or their champions fought. The party losing, usually by crying craven, had to pay a fine of 60s. If the grand assize was chosen, the action was removed to the Royal Court. A writ of grand assize was issued as follows: "The king to the sheriff, greeting. Summon by good summoners the following twelve, namely, A. B. …, to be before me or my justices at a certain place on a certain day, ready to declare on oath whether N. or R. has the greater right in one hide of land (or other things claimed) which the aforesaid R. claims against the aforesaid N., who is tenant, and in respect of which the aforesaid N., who is tenant, has put himself upon my assize and has sought a recognition to determine which of them has the greater right in the things claimed. And meanwhile the twelve shall view the land (or tenements [including meadows, pastures, woods, wastes, and rights of common] from which the services are demanded). And summon by good summoners N., who is tenant, to be there to hear the recognition. Witness…" The claimant could object to any of the twelve knights for just cause as determined by the court. Each of the twelve gave an oath as to whether the plaintiff's or the defendant's position was correct. This oath was not to speak falsehood nor conceal truth according to knowledge gained by eyewitness or "by the words of their fathers and by such words as they are bound to have such confidence in as if they were their own". If any did not know the truth of the matter, others were found until twelve agreed [the recognitors] on which party had the greater right. Perjury was punished by forfeiture of all one's goods and chattels to the king and at least one year's imprisonment. If the tenant in court vouched another to warranty, such as the lord to whom he paid homage, that warrantor would stand in his place in the proceedings. If the warrantor lost, he would have to give to his vassal equivalent land in exchange. Burgage tenure was not usually decided by assize. Also, if the parties were relatives, neither the assize nor the combat was available to them, but the matter had to be decided by the law of inheritance.
