Final answer:
When advising a spouse about their interest in a Will, a lawyer should explain that they may be entitled to an inheritance, which encompasses the assets and property received from the deceased spouse's estate.
Step-by-step explanation:
When advising a spouse regarding their interest in a Will, a lawyer should explain that they may be entitled to inheritance. Inheritance refers to the assets and property that a person is entitled to receive upon the death of a relative, in this case, the spouse. This derives from various legal traditions and laws that recognize the spousal right to a portion of the deceased's estate, which may include money, real estate, and other personal property. Other options such as alimony, child custody, and property rights do not directly relate to the benefits one may receive from a will, as alimony is a financial support paid to a former spouse following a divorce, child custody relates to the legal guardianship of children, and property rights may involve aspects of ownership but don't solely derive from the contents of a will.
