The content of a will does not always correspond to the expectations of the surviving relatives. That can be a painful surprise.
For example, contrary to expectations, one appears to be disinherited, the inheritance is considerably smaller than was counted on or an inheritance or legacy is granted to another.
Can the will then be affected?
