There are two alternatives to traditional marriage for same-sex couples in Israel:
1. Recognition of “Reputed Couples” (common-law partners), which enjoy similar legal rights and duties as legally married couples, per judicial findings in HCJ 1000/92 Bavli v. The Great Rabbinical Court (1994);
2. Registration before the Israeli Population Registration of marriages celebrated abroad, which renders the civil (legal) status of reputed and/or same-sex couples equal to that of legally married couples -per the Israeli High Court ruling in Yossi Ben-Ari and others v. Director of Population Administration, Ministry of Interior (2006).

Same-sex marriage is not legal in Israel. However, same-sex marriages celebrated abroad can be registered before the Israeli Population Registry per the Israeli High Court ruling in Yossi Ben-Ari and others v. Director of Population Administration, Ministry of Interior (2006), which renders the civil (legal) status of reputed and/or same-sex couples equal to that of legally married couples.
In June 2021, after several Israeli couples received civil marriage licences onine from the US state of Utah without having to physically travel abroad, the Population Registry announced that it would stop recognising unions issued online from Utah. However, several couples (including same-sex couples) married online filed a lawsuit. A court in Lod ruled in their favour, thus validating their marriages.

So Civil unions and Foreign same-sex marriage are recognized in Israel.
