A postnuptial agreement is like a prenup, but signed after the wedding. And when couples start thinking about one, a common question comes up: Do we need a lawyer for this?
The truth is, postnups can be legally complex. They often involve detailed conversations about how to handle finances, inheritance, debt, and long-term responsibilities after you're already married.
Simply put: While it’s technically possible to draft a postnup without a lawyer, proper legal guidance makes a huge difference.
In this post, we’ll look at whether you need a postnuptial agreement lawyer, what they do, and what they typically cost. We’ll also explore how Neptune makes the process smoother, smarter, and more affordable with flat-fee pricing and expert support from start to finish.

Can you manage your postnup without a lawyer? Yes, but it’s risky. While you can find postnup templates online or attempt to draft your own, most courts will only enforce a postnuptial agreement if:
Skipping legal support might save money in the short term, but it can lead to expensive complications later. One common reason postnups get struck down in court is that only one partner had a lawyer, or neither did.
Poorly written or one-sided postnups are not only unenforceable, but they can also erode trust between partners if they feel rushed or one-sided.
That’s why many couples eventually turn to postnuptial agreement lawyers. However, traditional legal routes often come with high hourly rates, confusing paperwork, and inconsistent support.

A postnup lawyer helps you:
Postnup lawyers also ensure that each spouse has had a chance to review the terms independently. This step helps protect the validity of the document and provides both parties with peace of mind.
The postnuptial agreement lawyer cost varies depending on where you live, the complexity of the agreement, and the lawyer’s billing structure. Most traditional law firms charge by the hour, with rates ranging from $250 to over $700 per hour.
That hourly rate usually covers:
Many lawyers bill for every interaction, including brief meetings, emails, or even sessions that are cut short due to missing documents. The meter keeps running, regardless of whether real progress is being made.
