Death registration

Hi everyone,

If there is a death registration there would also exist a church death document correct?
But with Guadalajara being such a big city and lots of churches it would be difficult to find?

Thank you,

I have not ever found a death record, comparable to a civil record. However, it is normal for there to be church records of "sepultura eclesiástica," which may or may not give any indication of the death date.
