        (1)    the date on which the lien is:
            (i)    satisfied; or
            (ii)    released by the tax collector because the lien is:

                2.    uncollectible; or
        (2)    20 years after the date of assessment.
    (b)    (1)    Except as otherwise provided in this subsection, a lien for unpaid inheritance tax:

            (ii)    continues for 20 years.
        (2)    If the property is subject to a special valuation under § 7–211 of this article, a lien:
            (i)    arises on the date on which the interest in the property vests in possession; and
            (ii)    continues for 20 years.
        (3)    If the unpaid inheritance tax is attributable to the disqualification of property that was qualified for special valuation or exemption under § 7–211 of this article, the lien:
            (i)    arises on the date on which the decedent died; and
            (ii)    continues for 20 years.
