My divorce advice is really marraige advice. Don't do it. But... since we know that love is real, i guess.. lol here is my advice.
Get two attornies. One for you, and one for your bride. Hammer out a reasonable prenup. Don't try and get the woman to sign it without her own attorney. Also don't let your attorney advise her and do it by him/herself because its a conflict when challeneged in many courts. Then lastly don't make it unreasonable. Don't say she gets nothing. Say she gets X amount but make it like 20% instead of the half she will get if prenup gets tossed. Also don't make the mistake of handing her the prenup as she is getting ready to walk down the aisle. Some states stuff like this flys but in many prenups done under above conditions getting tossed.
