Howe v Earl of Dartmouth (1802) 7 Ves 137 is an English trusts law case. It laid down the rule of equity in relation to the duties of a trustee in relation to a trust fund where there are successive interests in relation to the trust fund, and seeks to strike a fair balance between the rights of the life tenant and the remainderman. It is one of a number of highly technical common law rules which causes considerable angst where wills and trusts have not been professionally prepared.
