(1) If the heir has unlimited liability for the obligations of the estate, the provisions of sections 1973 to 1975, 1977 to 1980 and 1989 to 1992 do not apply; the heir is not entitled to apply for an order of administration of the estate. However, the heir may rely on a limitation of liability occurring under section 1973 or under section 1974 if the case of section 1994 (1) sentence 2 or of section 2005 (1) later arises.
(2) The provisions of sections 1977 to 1980 and the right of the heir to apply for an order of administration of the estate are not excluded by the fact that the heir has unlimited liability towards individual creditors of the estate.
