Although it is theoretically possible to write a will without the assistance of an attorney, it is unwise to do so. Not all assets you control are governed by a will. Joint property with the right of survivorship, for example, passes independently of a will. Elizabeth automatically inherits the house without regard to what Tim's will might say. Similarly, life insurance is paid out to the named beneficiary without regard to the will.
Many individuals have death benefits under an employer-provided pension plan.
These too are not governed by the will, but are paid to whomever the employee has designated. Remember, a will only takes effect upon the death of the person who created it. As sole owner, the survivor who has disabilities must live in the home, otherwise benefits may be jeopardized. A house can be left to a trust to administer on behalf of the person with a disability. This type of plan should be carefully worked out with an attorney.
