In Missouri, a beneficiary deed allows a person to make a deed conveying his real estate upon his death. This is a unique tool as it allows someone to pass property without going into probate. Unlike a quite claim deed or other present conveyance, the beneficiary deed does not require the grantee's signature if the person would like to cancel the deed (Perhaps, he would like to sell his home instead.) or convey to someone else upon his death. The person making the beneficiary deed can change his mind at any time before he dies.
Other tools are the Power of Attorney and Trust. These tools can be combined, and, when properly used, such tools can minimize the chances of having to probate an estate. Your attorney can help you decide what tools will work for you in your particular situation.
