$20 million but you have to get divorced

Tax free, your former spouse gets none of the money.

You can’t remarry the person you divorced. Nor can you live together. Full separation and they immediately start dating someone else.

Split custody if you have kids.

You CAN marry someone else, but that’s up to you.

If you aren’t yet married, the offer is on the table but you have to get married and then get a divorce.

Edit: For those who aren’t so eager…If $20M isn’t enough. Is there any number that is? $20 billion?
