The single biggest way in which you can protect your assets from your wife is to make sure that she signs a prenuptial (premarital) agreement before you marry her. A prenuptial agreement provides much flexibility in deciding how assets and debts will be divided during a divorce. Most importantly, you can eliminate or greatly reduce what some call “legal theft” or “financial slavery,” otherwise known as alimony or spousal maintenance. But if it is too late for that, you could try to get her to sign a postnuptial agreement. Postnuptial agreements are permitted in Arizona. But you must proceed very carefully because this is a tricky area of the law.
