Consists of a manuscript indenture in six parts on four vellum sheets (70 x 90cm) recording the sale, for £12,000, of the Mount Charles Plantation in Saint Thomas Parish, Jamaica, to Sir Henry Clinton (1738?-1795), a British army officer and politician who sat in the House of Commons between 1772 and 1795 and served as Commander-in-Chief of the British forces during the American Revolutionary War. The sale included the Mount Charles Plantation (later known as the Middleton Plantation), as well as another parcel of land known as "Middleton Penn," 247 enslaved laborers (all of whom are listed by name and occupation), and all future children born to the enslaved women listed.

The indenture first recites a deed dated September 24, 1768, which was the original document of sale between Charles Pole (seller) and Augustin Gwyn (purchaser). Gwyn, still owing money for the original purchase, sold shares in the ownership of the plantation in order to pay off his debt to Pole. Investors, named as the third party, who paid varying sums directly to Pole, include Simon Fanshawe of Hanover Square, Lewis Vickers of Holyhead, Patty Parsons of Hanover Square, Dorothy Askew of Wakefield, and numerous others. The document then records the sale of the estate by Gwyn to the fourth party, named as General Henry Clinton of Weybridge, and Matthew Brickdale of Clifton. The fifth and sixth named parties are listed as Charles Fanshawe of Inner Temple, William Bond of Walbrook, and Thomas and Clayton Case, who were Liverpool merchants and owners of slave ships. Charles Pole, 1695-1779, fifth son of Samuel Pole of Redbourne Hall, was a Liverpool merchant and Member of Parliament. Matthew Brickdale, 1735-1831, was a Bristol clothier, undertaker, and Member of Parliament who reportedly inherited £100,000 after the death of his father; he also owned the Hope Estate in St. Vincent and another plantation on Nevis. In 1832, prior to the abolition of slavery by the British in 1833, 61 enslaved women and 47 enslaved men were held in bondage on the Middleton Plantation.
