Last Will
We need a Last Will and Testament for married couple with NO children. Beneficiary under the Will is of course, 100% to spouse. We also want to designate alternate beneficiaries to take in trust. Please advise as to which form allows us to set up in the event both my husband and I die, then we would want to leave the money we have to a sister in trust so we need the trust provisions. We also have a couple of other alternate beneficiaries and would like to leave their portion to them in trust as well. Should we be considering a living will or can we accomplish this with a Will designate alternate beneficiaries who take in trust?
