With an insurance trust, your trust owns the policy. The trustee you select must follow the instructions you put in your trust. And with your insurance trust as beneficiary of the policies, you will even have more control over the proceeds.
For example, your trust could allow the trustee to use the proceeds to make a loan to or purchase assets from your estate or revocable living trust, providing cash to pay taxes and expenses. You could provide your spouse with lifetime income and keep the proceeds out of both of your estates. You could keep the money in the trust for years and have the trustee make distributions as needed to trust beneficiaries, which can include your children and grandchildren. Proceeds that stay in the trust can be protected from courts, creditors (even spouses) and irresponsible spending.
By contrast, if your spouse or children are beneficiaries of the policy, you will have no control over how the money is spent. If your spouse is beneficiary and you die first, all of the proceeds will be in your spouse’s taxable estate; that could create a tax problem. Also, your spouse (not you) will decide who will inherit any remaining money after he or she dies.
