Some people have already alluded to this. Marriage between same-sex partners from places like Canada, the Netherlands and other European countries are recognised here in Israel (ID cards state "married"). Married gay couples should therefore have exactly the same rights in family law matters as married straight couples. Obviously these 2 men were not married and the fact that 2 men or 2 women cannot get married in Israel itself is merely due to the nature of marriage in this country. Once we get civil marriage, gay marriage will hopefully follow soon. I don't know the specifics of this case. A lot of doubt seems to have been cast on the nature of the relationship between these 2 men. I also know that Israeli inheritance law is not half as straight forward as in some other countries. I hope this is a case with very specific circumstances and that it doesn't impact the gradual development towards a more inclusive policy.
