If someone files an objection to the Will, or produces another will, what is known as a “will contest” has begun. While will contests are not that rare, and while some people actually win one, they can be extraordinarily costly and create incredible delays.
It is not just anyone that can contest a will. To properly contest a will a person must have “standing” to object to its probate. This would be someone who had a legal interest in an estate of the person whose will is in question. Generally, spouses, children, grandchildren and other family members and heirs may have “standing” to challenge a will.
