My fiance and I wish to sign a prenuptual agreement before getting married, but are reluctant to pay the high costs of lawyers to get this done. we have found some DIY websites and software online for a fraction of the price of a lawyer. Though, we are a little unsure as to how secure these DIY methods are. If we create a DIY prenup using the right software, and have it notarized at the bank, will it be legit? Will it hold up in court?
