Do non-Jews have laws of inheritance in halacha? If so, what are they?
Okay... that's not my real question, though I think it's a good part of my real question; in the interests of avoiding the so-called X-Y problem, I'll state my real question in full.
Someone I know obtained a utensil that required t'vila (immersion in a mikve) and was unable to immerse it before he needed to use it, so instead gave it to a non-Jew and borrowed it for long-term use (on an indefinite loan, that is one with no term).
The non-Jew has now died.
Who owns the utensil?
- If the Jew owns it now (e.g., perhaps, if there is no halachic law of inheritance for non-Jews, their stuff becomes hefker, and whoever has possession acquires it), does he have to immerse it?
- If someone other than the Jew owns it now, then does the Jew need to return the loan? (Does he need to notify the owner, or can he just hold on to the item until such time as the owner claims it, even if that's never going to happen?)
Sources or arguments, please.
And yes, I know: I won't rely on answers what I read on this site for practical halacha.
