N.H. Rev. Stat. Ann. § 561:7-a

The personal estate of a person deceased which was not bequeathed or included in a bequest and which remains in the hands of the executor or administrator upon settlement of an account of such fiduciary shall be distributed according to law by decree of the judge. Upon the application of the fiduciary or any interested person, the judge may issue interim orders approving or directing partial distributions or granting other relief at any time during the pendency of administration to effect distributions as expeditiously and efficiently as may be consistent with the best interests of the estate.
