The contents and stipulations in a prenuptial agreement are what make it up, but there also concerns and issues that touch upon the finances and properties. For as long as the stipulation is capable of pecuniary estimation, it may be included in a prenuptial agreement. Included in the agreement could be the way the money is handled and the payment of expenses.
It is not impossible for parties to miss out on certain issues that cannot easily be prepared or expected by the parties, including the custody agreement, visitation schedule, the spousal support and the like. Although these are not usually included, some states may allow these to be part of the agreement.
