then, set up a trust now with both you and your hu*****and as grantors and start moving both yours and his assets into the trust with your children as the beneficiaries....also, maybe buying life insurance would be a great way to ensure that your children would have something to them...of course, try to pay with his money :)
I would strongly encourage you to seek legal counsel if large amount of assets are invovled and you are truely worried....comparing to the seriousness of the consequences, it might worth paying for a good estate planning attorney to take care of the matter...
