After Beale's death in 1912, Margaret Beale continued to live at Standen. When she died in 1936, their unmarried daughter, Margaret, succeeded her, and after her death in 1947, Standen came into the possession of Helen, their youngest daughter, also unmarried. On Helen's death in 1972 the house passed by bequest to the National Trust for Places of Historic Interest or Natural Beauty.
