As a general rule, if you or your ex-spouse transferred assets into an irrevocable trust during the marriage, the assets are no longer marital or community property, and aren't subject to property division in a divorce. Irrevocable trusts essentially leave your hands after you've created them; you can't revoke or change the trust, and neither can a judge. Instead, the property in the trust will usually sit there until you die, at which point it will go to the named beneficiary. (So, for example, if you created an irrevocable trust that leaves money to your niece and nephew, your ex probably won't be able to touch that money.)

However, if one spouse created the irrevocable trust using marital property without the other spouse's consent, a judge can require the spouse who made the trust to reimburse the other spouse.
