Are wills ("last will and testament...") registered anywhere? (Hudson County, NJ)? - nj last will and testament

My father just died, and his (second) wife was less than forthcomeing your needs and desires. I know that I've written, I'm pretty sure he see a lawyer. Is there any way to get a copy of his will? We do not know what he wanted for relations with funerals or services for the end user.
