Sometimes the Executor of an Estate may take advantage of the situation and hide assets or act against the Will in different ways.  This can cause a dispute between parties and cause a lot of confusion.  Sometimes there are multiple Wills, confusing instructions attached to the Will or simply failed to list the proper parties as beneficiaries on insurance policies or pension plans correctly.  A lawyer who is experienced in Estate Planning should be sought out  to settle any disputes so it is taken care of legally and within the law.
