Except as provided in section 45a-242, administration of the estate of any person shall not be granted, nor shall the will of any person be admitted to probate, after ten years from his decease, unless the Court of Probate upon written petition and after public notice and hearing finds that administration of such estate ought to be granted, or that such will should be admitted to probate; but when any minor is interested, one year shall be allowed after his arrival at the age of majority to take out administration or to cause such will to be proved. In all cases where any person has died leaving property which is not known to those interested in the same within the time above limited, but is discovered afterwards, administration may be granted within one year after its discovery.
