When the monastery was founded, Leofric gave the northern half of his estates in Coventry to the monks to support them. This was known as the "Prior's-half", and the other was called the "Earl's-half" which would later pass to the Earls of Chester, and explains the early division of Coventry into two parts (until the Royal "Charter of Incorporation" was granted in 1345). In 1250, Roger de Mold (referred to in older documents as "Roger de Montalt"), the earl at the time who had gained his position by marriage, sold his wife's rights and estates in the southern side of Coventry to the Prior, and for the next 95 years the town was controlled by a single "land lord". However, disputes arose between the monastic tenants and those previously of the Earl, and the Prior never gained complete control over Coventry.
