Well, that depends on your family make-up. Generally speaking, this is what will happen:
If you do not have a spouse or kids, your parents will inherit your estate. However, this can be problematic for elderly parents who are looking to spend down their estate in an effort to qualify for medical assistance. An inheritance received by your parents may disqualify them from services or essentially go straight to a nursing home.
If you are married with no kids, your spouse will get the first $30,000 of your estate and your spouse AND PARENTS will split everything else. Many people think that because they are married that their spouse inherits everything. However, unfortunately, the law states otherwise. Your spouse may be left financially strapped or your parents may wind up ineligible for medical assistance.
