Howard will need to protect that $650 Million nestegg of his - here is some advice from Askmen.com on how to break the news to Beth:

The easiest way to convince your girlfriend to sign is by making it clear that it’s to protect both of you, not just you. And make sure to explain that you in no way expect to get a divorce in the future. Don’t lead her to believe that you’re planning your exit strategy. Explain that this is simply a “just in case” plan.

Mention it early on
It’s a good idea to bring up the prenup issue early on in the relationship, and definitely before getting engaged, in order to gauge her feelings about the issue.

Answer all her questions
Ask her what she knows about prenups. Make her understand that it’s not you against her; you both have input when it comes to the contract. Make her understand that it’s not about her getting nothing if you part ways. Don’t leave her with doubts.

Ask her to put emotion aside
Ask her to be logical about the situation. Although this will likely be difficult for her (it is for most women), if she really cares for you, she’ll put forth the effort.

Ask her to get legal advice
She will eventually see the benefits of a prenup on her own. Tell her you love her, and that this is just insurance.

Mention that it can prevent cheating
You can include a clause about cheating, if she begins to question your fidelity. Keep in mind that if you agree to do this, then she should have no problem attesting that she’ll remain faithful as well.

State that it takes care of your children
A prenup allows you to plan for custody of any future children. It lets you plan for potential future child support and alimony payments, should things take an unfortunate turn in the marriage.
