2,186. The Status of Shetuki and Asufi Offspring
Hilchos Issurei Biah 15:24
If a shetuki or an asufi marries a convert woman or a freed servant woman, or if a convert or a freed servant marries a female shetuki or asufi, their children are shetukim or asufim.
Hilchos Issurei Biah 15:25
If an asufi is found in a city where non-Jews live, regardless of whether the majority of residents are Jewish or non-Jewish, the child is presumed to be a non-Jew of doubtful lineage. If he betroths a woman, she needs to be given a get because of the doubt. If someone kills this person, he is not liable to execution.
