William was only 12 when his father died. The wardship of William and the de Braose lands were granted by Henry III to Peter des Rievaux. On his fall in 1234 these custodies were passed on to the king's brother, Richard, Earl of Cornwall. When William came of age he took control of the Braose lands in Gower, Bramber and Tetbury. He confirmed the grants made by his father of the rents of cottages in Tetbury to the priory at Aconbury, founded in memory of Maud de St Valery by her daughter Margaret. (The sites of the cottages are known - picture right.)

He was plagued throughout his life by a series of legal battles with his female relatives.

William died at Findon on "the day of Epiphany" (January 6) in the year 1290/1. His funeral was at Sele Priory on January 15.
