Hmm. That would be a problem, wouldn't it, as the State frequently issues nonbiblical divorces and then those people could marry in the Church and their new marriage might be invalid.

Yeah, I think the State getting involved in marriage has caused chaos, such as an increase divorce, since they let anyone to do it, as well as mucking things up by introducing same-sex so-called "marriage."
The state basically downgraded its marriages to a sort of "partnership contract".
Sensible would be to require the contract before performing the religious wedding or granting a religious divorce or annulment, to prevent chaos, but to never view the contract as a substitute for the church issuing a decree.
