That depends very much on where you live. It doesn't reflect the law (as I understand it) here.A will to protect asserts or children, etc. would be more beneficial. But most areas have laws with presets to determine how assets should be distributed. For instance a wife or husband marrying into an already established estate is only eligible for half of the increase in value from that time forward, or another example, inheritances to either spouse from other sources remain the sole property of the inheriting spouse and not their mate, etc.
Prenuptial agreements are not just in case of divorce it is good to have if there are children involved from a previous marriage. That being said, if one party is deliberately protecting themselves from spousal support then the foundation of the marriage is starting off on shaky grounds. Blessings.Divorce unfortunately happens in and out the church should a Christian person protect their finances and get a prenup before marriage.
