At such settlement, the court must decree to each creditor whose claim has been allowed, as provided in this article, his proportion of all moneys then found due from such executor or administrator, reserving in his hands a ratable proportion of such moneys for such claims as may be then contested and undecided; and a similar settlement and distribution must be made at least every six months thereafter, at such times as the court may appoint, until the estate is finally settled and distributed.
