Am I entitled to see a copy of the Will before it goes to Probate?

The only people who are legally entitled to sight of a Will before a Grant of Probate is issued are the executors who are named in the Will.  That being said, it is common practice for an executor to provide a copy of the Will if it is requested.

Once a Grant of Probate is issued, the Will is then a public document and can be readily accessed by anybody who wishes to see it.
