If you die intestate (without a will), your state's laws of descent and distribution will determine who receives your property by default. These laws vary from state to state, but typically the distribution would be to your spouse and children, or if none, to other family members. A state's plan often reflects the legislature's guess as to how most people would dispose of their estates and builds in protections for certain beneficiaries, particularly minor children. That plan may or may not reflect your actual wishes, and some of the built-in protections may not be necessary in a harmonious family setting. A will allows you to alter the state's default plan to suit your personal preferences.

A will provides for the distribution of property owned by you at the time of your death in any manner you choose (subject to the forced heirship laws of some states that prevent disinheriting a spouse and, in some cases, children). Your will cannot, however, govern the disposition of properties that pass outside your probate estate (such as certain joint property, life insurance, retirement plans and employee death benefits) unless they are payable to your estate.

Wills can be of various degrees of complexity and can be utilized to achieve a wide range of family and tax objectives. Aside from providing for the intended disposition of your property to spouse, children etc., there are a number of other important objectives that may be accomplished in your will. Good planning can also enhance your support of religious, educational, and other charitable causes.

The term trust describes the holding of property by a trustee (which may be one or more persons or a corporate trust company or bank) in accordance with the provisions of a written trust instrument for the benefit of one or more persons called beneficiaries. A person may be both a trustee and a beneficiary of the same trust. A trust created by your will is called a testamentary trust and the trust provisions are contained in your will.

Trusts are not only for the wealthy. Many young parents with limited assets choose to create trusts either during life or in their wills for the benefit of their children in case both parents die before all their children have reached an age deemed by them to indicate sufficient maturity to handle property. This permits the trust estate to be held as a single undivided fund to be used for the support and education of minor children according to their respective needs, with eventual division of the trust among the children when the youngest has reached a specified age. This type of arrangement has an obvious advantage over an inflexible division of property among children of different ages without regard to their level of maturity or individual needs at the time of such distribution.

The term "living trust" is generally used to describe a trust (a) which you can create during your lifetime and (b) which you can revoke or amend whenever you wish to do so. You can also create an "irrevocable" living trust, but that is permanent and unchangeable and is almost exclusively done to produce certain tax results beyond the scope of this summary.

A "living trust" is legally in existence during your life, has a trustee who is currently serving, and owns property which (generally) you have transferred to it during your life. While you are living, the trustee (who may be you) is generally responsible for managing the property as you direct for your benefit. Upon your death, the trustee is generally directed to either distribute the trust property to your beneficiaries, or to continue to hold it and manage it for the benefit of your beneficiaries. Like a will, a living trust can provide for the distribution of property upon your death. Unlike a will, it can also (a) provide you with a vehicle for managing your property during your life and (b) authorize the trustee to manage the property and use it for your benefit (and your family) if you should become incapacitated, thereby avoiding the appointment of a guardian for that purpose.

If you own property with another person as joint tenants with right of survivorship, that is, not as tenants in common, the property will pass directly to the remaining joint tenant upon your death and will not be a part of your probate estate. (It will, however, be a part of your taxable estate.) Frequently, people (particularly in old age) will cause bank accounts or securities to be placed in the name of the owner with one or more children or trusted friends as joint tenants with right of survivorship. This is sometimes done as a matter of convenience to give the joint tenant continuing access to accounts to pay bills.

If you own life insurance on your own life, you may either:
(a) designate one or more beneficiaries to receive the insurance proceeds upon your death, or
(b) make the proceeds payable to your probate estate or to a trust created by you during your lifetime or by your will.

An important part of lifetime planning is the power of attorney. Valid in all states, these documents give one or more persons the power to act on your behalf. The power may be limited to a particular activity (e.g., closing the sale of your home) or general in its application, empowering one or more persons to act on your behalf in a variety of situations. It may take effect immediately or only upon the occurrence of a future event (e.g., a determination that you are unable to act for yourself). The latter are "springing" powers of attorney. It may give temporary or continuous, permanent authority to act on your behalf. A power of attorney may be revoked, but most states require written notice of revocation to the person named to act for you.

The person named in a power of attorney to act on your behalf is commonly referred to as your "agent" or "attorney-in-fact." With a valid power of attorney, your agent can take any action permitted in the document. Often your agent must present the actual document to invoke the power. However, your agent generally should not need to present the power of attorney when signing checks for you.

Why would anyone give such sweeping authority to another person? One answer is convenience. If you are buying or selling assets and do not wish to appear in person to close the transaction, you may take advantage of a power of attorney. Another important reason to use powers of attorney is to prepare for situations when you may not be able to act on your own behalf due to absence or incapacity. Such a disability may be temporary (e.g., due to travel, accident, or illness) or it may be permanent.

You may wish to choose a family member to act on your behalf. Many people name their spouses or one or more children. In naming more than one person to act as agent at the same time, be alert to the possibility that all may not be available to act when needed, or they may not agree. The designation of co-agents should indicate whether you wish to have the majority act in the absence of full availability and agreement. You should name a successor agent to address the possibility that the person you name as agent may be unavailable or unable to act when the time comes.

There are no special qualifications necessary for someone to act as an attorney-in-fact except that the person must not be a minor or otherwise incapacitated. The best choice is someone you trust.

It is a document, signed by a competent adult, i.e., "principal," designating a person that the principal trusts to make health care decisions on the principal's behalf should the principal be unable to make such decisions. The individual chosen to act on the principal's behalf is referred to as an "agent."

It is effective immediately after it is executed and delivered to the agent. It is effective indefinitely unless it contains a specific termination date, it is revoked, or the principal becomes competent.

An agent may make health care decisions on the principal's behalf only if the principal's attending physician certifies in writing that the principal is incompetent. The physician must file the certification in the principal's medical record.
