Peter Maverick was ordained as a deacon on 15 January 1573, and as a priest three months later and then was admitted to the Perpetual Vicarage of Awliscombe on the resignation of Richard Bacon on 3 November 1580.

In 1612 Peter Maverick sued William Champneys over the 99-year lease between the two for Champneys’ land. Vicar Maverick made a down payment, but upon the anniversary of the second payment, Champneys denied knowing anything about the extended lease. Apparently Champneys had discovered that a neighbor would have given him more money. Champneys made up a new lease, for one year, with unreasonable demands to which Peter Maverick agreed. A few months later, Champneys evicted the good Vicar. Before the matter could be settled completely and satisfactorily to both parties, Vicar Peter Maverick died a violent death early in the year 1616.
