(2) Nevertheless, such acceptan ce shall not operate so as to prejudice any right which may have been acquired by third parti es over the property of the inherita nce either by prescription, or by virtue of acts validly made with the curator of the vacant inheritance. Heir may be compelled to declare whether he accepts or refuses.
