Prenup for professional with significant student debt in California

Planning to get married soon and we're on discussion about prenup, I have significant amount of student debt while our financial situations are otherwise fairly different.

​I want to understand how do you define which debts remain separate, and how future payments or new debt taken during the marriage are handled?

​What should I include in my prenup about debt?

​I'm not looking for legal advice​, just want to know how other people handling similar things​.
