Idaho Code § 32-906A
Where community property, before or after the effective date of this section, is transferred by the husband and wife to a trust, regardless of the identity of the trustee, which trust originally or as amended prior or subsequent to such transfer (a) is revocable in whole or in part during their joint lives, (b) provides that the property after transfer to the trust shall remain community property and any withdrawal therefrom shall be their community property, and (c) is subject to amendment or alteration during their joint lifetime upon their joint consent, the property so transferred to such trust, and the interests of the spouses in such trust, shall be community property during the continuance of the marriage, unless the trust otherwise expressly provides. Nothing in this section shall be deemed to affect community property which, before or after the effective date of this section, is transferred in a manner other than as described in this section or to a trust containing different provisions than those set forth in this section; nor shall this section be construed to prohibit the trustee from conveying any trust property, real or personal, in accordance with the provisions of the trust without the consent of the husband or wife unless the trust expressly required the consent of one or both spouses.
