Samantha is told by her friend Cassie (who should know) that she can not see the will because it's not a public document. The very purpose of a will is to put an estate IN the public record, for all to see, so that claim-holders can see what is available to both heirs and creditors. The plot even has Samantha go so far as to commit a burglary of the attorney's office to steal a copy of the will.
When Philby does a license plate search on the black Saturn that almost hit Samantha, the results indicate a 2-door Saturn. However, the car can clearly be seen to have 4 doors.
