Israeli law recognizes same-sex marriages performed elsewhere... It does not, however, allow same-sex couples to marry on Israeli soil. Civil marriage doesn't exist in Israel for heterosexual couples, either, (except where both spouses are non-Jewish) and therefore only a marriage sanctioned by religious authorities can take place within Israel.
The State of Israel allows foreign partners of its homosexual citizenry to receive residency permits. The Civil Service Commission extends spousal benefits and pensions to the partners of homosexual employees. The Israeli State Attorney's Office has extended the spousal exemption from property-transfer taxes to same-sex couples. Israel's attorney general has granted legal recognition to same-sex couples in financial and other business matters. Attorney General Meni Mazuz said the couples will be treated the same as common-law spouses, recognizing them as legal units for tax, real estate, and financial purposes. Mazuz made his decision by refusing to appeal a district court ruling in an inheritance case that recognized the legality of a same-sex union, his office said in a statement. Mazuz did differentiate, however, between recognizing same-sex unions for financial and practical purposes, as he did, and changing the law to officially sanction the unions, which would be a matter for parliament, according to the statement.
