921. The Property of a Convert Without Heirs

Eiruvin 2:7

If there are two houses on opposite sides of a public domain and non-Jewish neighbors surround the area with a partition on Shabbos, the owners of these houses cannot cede their ownership rights to one another because it was not possible to make an eiruv before Shabbos began. Let’s say that one of the residents of a courtyard dies and leaves his property to an heir that lives elsewhere. If he died before Shabbos began, the inheritor impedes the residents from carrying because he is not a resident. If the person died after Shabbos began, the absentee inheritor does not impede the residents’ ability to carry. If a non-resident owner dies and leaves his property to one of the residents, then if he died before Shabbos began, carrying is not impeded because all of the residents participated in the eiruv. If he died after Shabbos began, the residents may not carry until the inheritor forgoes the ownership rights he inherited in favor of the other residents.

Eiruvin 2:8

Let’s say that a born Jew and a convert are in a cave together and the convert dies before Shabbos. [Unless the convert had children after converting, he has no halachic heirs.] If another Jew takes possession of the deceased’s property, even if he does not do so before Shabbos begins, he prohibits carrying until he cedes rights to the residents because he is considered an heir. If the convert died after Shabbos began, then even if another Jew takes possession of his property, he does not impede the ability to carry. Rather, the original eiruv remains in effect.
