I Just Wanted the Prenup to Cover One Thing — Turns Out That's Not How It Works

My dad wants my husband and me to do a prenuptial agreement — just to protect my inheritance if we ever divorce, split everything else 50/50. So I went to a lawyer to ask about doing just this one part, and was told they don't do agreements covering just one piece — if they take this on, they need to look at everything: property, vehicles, bank accounts, all of it.

Why "Just This One Part" Isn't Really How These Documents Work

Some legal documents are built so you can pick and choose what goes in them, almost like building blocks. A prenuptial agreement generally isn't one of those. Because it's meant to hold up as a full picture of a couple's finances, leaving major pieces out on purpose can actually weaken the parts that are included.

Case Study: The Simple Prenup That Cost Thousands

Fatima and her partner figured their prenup would be quick and cheap — no debt, no kids, nothing to argue about. When the quotes came back in the thousands, Fatima was surprised. The cost isn't really about how much the couple disagrees — it's about the document needing full, independent legal review on both sides to be considered valid at all.

What You Can Actually Do

The Bottom Line on Prenuptial Agreements

Wanting a document to cover "just one thing" is a completely reasonable ask — but some legal documents simply aren't built to work that way.

Frequently Asked Questions

Can a prenuptial agreement cover just one asset, like an inheritance?

Generally not on its own — most lawyers require a full financial picture to be included, since leaving major assets out can weaken the whole document.

Why does a simple prenup still cost thousands of dollars?

Because the cost is tied to the required legal process (independent review for both parties), not how complicated or simple the actual agreed terms are.

Does agreeing easily reduce the cost of a prenuptial agreement?

Not usually — it may shorten the conversations, but the same legal steps are still required.

What if jointly-owned family property is part of the picture?

It can complicate what can actually be promised, since shared ownership adds another layer the agreement needs to address clearly.
