Two of the most foundational documents in any estate plan are the will and the trust.
Although each has an ultimate purpose of distributing your property and assets to the people you choose upon your death, these two documents are not interchangeable. In fact, for any estate plan a will is nearly indispensable whereas a trust may or may not make sense for your estate plan. In other words, while you can have a will without creating a trust, it is rare (and in most every case inadvisable) to create a trust without also drafting and executing a will.
Basics of Wills and Estate Plans
A will is a written document that is created and executed in accordance with statutory instructions that describes how you want property that you own at the time of your death to be distributed. The "formalities" that wills must follow include the requirement that at least two witnesses must observe the creation and execution of the will by the will's creator (called the "testator") and sign the will indicating they did in fact witness its execution. A will usually will name an executor or administrator that will oversee the distribution of the testator's assets after his or her death. If the testator has minor children, a legal guardian for those children may also be named in the event that both he or she and the children's other parent die and the court needs to appoint someone to care for the child.
Despite their essential nature, wills have some drawbacks, however. First, a will must be admitted to probate in order to be enforced. Not only does the probate process take time and resources to complete, but it also makes a public record of your affairs. Any obligation or asset you have that is resolved through your will (in all likelihood) will become a matter of public record that individuals can search and review. Also, when one or more assets pass to another individual through probate pursuant to a will, taxes may need to be paid on that asset or property (reducing its value to the beneficiaries).
