Is there a deadline for entering a prenuptial agreement?

I recommend familiarizing yourself with Family Code 1615.  There is a mention of 7 days in there.  What does this mean?  Several interpretations, but basically, you need to make sure your fiancee is reprsented by independent counsel and has sufficient time to understand the law.  Personally, I think alloting 3 months before your wedding date is the bare minimum.  Most people spend over a year planning a wedding – why spend any less on a legal document?
