LAST WILL AND TESTAMENT
In Tennessee, a will can be defined as a set of instructions for disposing of one's assets after death. A will can only be enforced through the probate court. That being said, a will provides your instructions, but it does not avoid probate. Any assets titled in your name or directed by your will must go through your state’s probate process before they can be distributed to your heirs. (If you own property in other states, your family will probably face multiple probates, each one according to the laws in that state.) The process varies greatly from state to state, but it can become expensive with legal fees, executor fees, and court costs. It can also take anywhere from nine months to two years or longer. With rare exception, probate files are open to the public and excluded heirs are encouraged to come forward and seek a share of your estate. In short, the court system, not your family, controls the process.
Not everything you own will go through probate. Jointly-owned property and assets that let you name a beneficiary (for example, life insurance, IRAs, 401(k)s, annuities, etc.) are not controlled by your will and usually will transfer to the new owner or beneficiary without probate. But there are many problems with joint ownership, and avoidance of probate is not guaranteed. For example, if a valid beneficiary is not named, the assets will have to go through probate and will be distributed along with the rest of your estate. If you name a minor as a beneficiary, the court will probably insist on a guardianship until the child legally becomes an adult.
