Absolutely! While you are alive and mentally competent, you have complete control over your property. You can buy, sell, improve, spend, change investments, or give away property just as you would without a trust. The trust can be modified in any manner you desire or it can be completely revoked. Upon your death, the trust becomes irrevocable so that no one can change your testamentary wishes. Upon your incapacity, your durable power of attorney comes into effect. For married couples, the surviving spouse still has total control over his or her share of property after its transfer to the survivor’s trust, and the trust becomes irrevocable only as to the deceased spouse’s share.
