He was the son of another Richard de Montfichet, whom
Henry II made forester of Essex. Richard the elder was the son of Gilbert, who married Avelina de Lucy, daughter of
Richard de Luci. Richard the elder was the grandson of William de Montfichet, founder of the abbey of Stratford-Langton Essex; he was with
Richard I in Normandy in 1195, was sheriff of Essex and Hertfordshire in 1202, and died the next year, leaving one son by his wife Milisent.
William de Warenne offered King John 500 marks for a licence to marry the widow Melisent. The young Richard was then about ten years old, and was at first a ward of
Roger de Lacy (1170-1211). He appears as witnessing several charters in 1214, and on 21 June 1215 received charge of the forests of Essex as his by hereditary right. He had nevertheless acted previously with the baronial party, and been present at the meeting at Stamford in March. He was one of the twenty-five barons appointed to enforce the observance of
Magna Carta, and as a prominent member of the party was excommunicated by the pope in 1216. He supported
Louis VIII of France both before and after John's death, and fighting at Lincoln against
William Marshal on 20 May 1217 was then taken prisoner. He returned to loyalty, and recovered his lands in the following October. In 1223, his lands were again for a time seized by the king in consequence of his presence at a prohibited tournament at
Blyth. In 1225, he was a justice-itinerant for Essex and Hertfordshire, and in the same year was a witness to the confirmation of Magna Carta. In 1234, he was admitted to sit as a baron of the exchequer, and in 1236 again witnessed the confirmation of the charter. He was justice of the forest for nineteen counties in 1237, and from 1242 to 1246 sheriff of Essex and Hertfordshire, the counties in which his estates lay. Montfichet was one of the baronial representatives on the committee to consider the king's demand for a subsidy in 1244, and probably, therefore. had a share in drafting the remarkable scheme of reform of that year. ==Family==
