On his death, the earldom was inherited by his two-year-old daughter,
Anne (14 February 14443 June 1449),
suo jure Countess of Warwick. She, however, died three years later, and there was some question regarding who, if any, of her father's sisters (or their heirs) should succeed. In the end, his full sister
Anne (who was married to
Richard Neville, eldest son of Richard Neville, Earl of Salisbury, and brother to Beauchamp's widow) was declared the heir, due to the English common law principle that "possession by the brother makes the sister the heir", which denies relatives of the half-blood from inheriting when full-blood relatives are available to inherit. The three half-sisters from their father's first marriage contested this decision, but to no avail. ==Ancestry==
