text: I'm not exactly a scholar of Arkansas state law, put a prenup is, first, a contract.  So it has to have all the same things a contract does.  The parties have to understand it, agree to it, and each give up something of value.  All of its terms have to be written down and it has to be sufficiently detailed so that it's not an "agreement to agree."\n\nPrenups are frequently signed between people of unequal power - one wealthy, one less so.  For that reason, most states will insist that the parties be given some extra rights.  Each must have access to an attorney, ample time to consider the prenup, and must have received fairly complete disclosure about the finances of the other.  One or more of these may be waived but the more unequal the position of the parties, the less likely courts will be to allow such waivers. \n\nSome states also require prenups to be sworn and notarized, a requirement not necessary for your average contract.\n\nAnd couples will have a hard time making an agreement about child support and visitation.  These issues are almost always open for the courts to re-decide them.
