But you can't completely safeguard yourself from these problems. So how do you keep financial mishaps from putting undue strain on your relationship? Like everything else in a marriage, communication is the key. Know each other financially and be willing to talk openly about your present -- and future -- financial situations.

Prenuptial agreements
The bad reputation it's earned in some circles notwithstanding, a prenuptial agreement is a solid concept. This statement upon which both parties agree to certain terms as they enter into the marriage may not be the most romantic topic of discussion during wedding preparations, but it's a realistic one. Couples on the brink of matrimony should at least consider drafting a prenuptial agreement.

From a legal standpoint, it is a good idea to create a prenuptial agreement if:


Leave yourself enough time before entering into the agreement that you can both think about it. It will make sure there is more clarity about the situation. It will also make the prenuptial agreement harder to challenge.

Postnuptial agreements
If you're already married or your wedding is coming up too quickly to get a prenuptial agreement arranged, but you still want some kind of financial contract, consider a postnuptial agreement. It accomplishes the same basic things as a prenuptial agreement does -- it's just signed after the parties have already married. Postnuptial agreements are often created when one partner comes into wealth and wants to protect it.
