The surviving spouse has complete control over the survivor's trust, which contains his or her property interests, but has limited control over the assets in the deceased spouse's trust. However, this limited control over the assets in the decedent's trust will still enable the surviving spouse to live in the couple's house and draw income from the trust, provided these terms are stipulated in the trust. Upon the death of the surviving spouse, the property in the decedent's trust passes to the beneficiary(s) named in this trust. As this property is not considered part of the second spouse's estate for purposes of estate tax, double-taxation is avoided.
