 If a secret trust can be shown, but not its terms (or communication post-dated the testator's death), then the would-be trustee will hold on resulting trust for the testator's estate.With a half-secret trust, the fact that the beneficiary of the will holds as trustee only is declared on the face of the will, but not the other terms of the trust.This must go further than the mere "hope" that the beneficiary (again I believe this should read "trustee" - the beneficiary is the passive party to a trust) of the will, will act in accordance with its terms.
