A lawyer and ‘gentleman’, Bisley was one of the guests who attended the wedding of John Heyward of Gloucester in about 1417. Some decades later Heyward’s son and namesake became prior of Llanthony by Gloucester, a house of Augustinian canons for which Bisley’s father, another lawyer, had acted as a steward. Bisley also served the priory, witnessing conveyances to it in 1430 and 1432 and arbitrating in a quarrel between it and Robert Bentham II* in 1439. By the early 1440s, however, he himself had fallen out with the prior and canons, who accused him of failing to surrender six properties in Gloucester which should have passed to them under a 14th-century will. He did arbitrate in a dispute between the burgesses of Gloucester and Prior John Garland in 1456, although as a nominee of the town rather than Llanthony priory.
Bisley inherited most of his family’s extensive holdings in Gloucester,
In spite of his extensive interests in Gloucester, it appears that Bisley did not follow in his father’s footsteps by holding municipal office there. Outside the town, he served on a handful of ad hoc commissions and attested the return to Parliament of the knights of the shire for Gloucestershire on at least eight occasions. Over the years he acted as a witness and trustee on behalf of various gentry from the county, including his fellow lawyers, John Langley II* and William Nottingham II*. Langley made Bisley a feoffee to the use of his last will and, in turn, was one of Bisley’s own feoffees, while Bisley was acting as a feoffee for Nottingham, the King’s attorney-general, by 1457.
It is unlikely that Bisley survived for many years beyond that date, for it would appear that he was no longer alive when his son and heir John conveyed lands in the Gloucestershire parish of Hazleton to Nottingham in May 1463.
