You do not need a get on divorce, or in order to get re-married in a Liberal Jewish synagogue.

Orthodox Judaism has developed, and maintains, elements of Jewish divorce that are unacceptable to Liberal Jewish values – one of which is the get.

However, Liberal Judaism also recognises that some other denominations of Judaism do require a get and that some couples like to have one. In these cases, the Liberal Judaism Beit Din can arrange for this.

Liberal Judaism also offers a mutual sefer-k’ritut document of separation.

Yes, and you would be very welcome.

Although for the benefit of you, your ex-spouse and any future children, it may still be advisable to get one.
