2007 is not last year.
You can get a copy of the will from the probate Registry if it went to probate. If it didn't there's really nothing you can do.
And I'm afraid that the fact that he told you he had a will doesn't mean that he did - or that it was valid. If it was made before his second marriage then that would have annulled it.
However - something in your style of writing/spelling suggests you may be in the USA. If so, laws could be different there - and I suspect vary from state to state.
