On 15 May 1220, after an intervention from the Pope and an agreement of the dowry, Joan was sent back to England where negotiations for her hand with Alexander II of Scotland were taking place.

On 18 June 1221, Alexander officially settled the lands Jedburgh, Hassendean, Kinghorn and Crail to Joan as her personal income.

Joan died in the arms of her brothers King Henry and Richard of Cornwall at Havering-atte-Bower in 1238, and was buried at Tarrant Crawford Abbey in Dorset in accordance with her wishes.

Most dramatically, in late 1252, almost fourteen years after her death, Henry ordered the production of the image of a queen in marble for Joan's tomb, at a great cost.

This was one of the first funerary effigies of a queen in England; the tradition developed in the early thirteenth century, but the tombs of Eleanor of Aquitaine and Berengaria of Navarre were in France.
