Lawyer vs DIY Prenup: What’s the Best Route for You in 2025?

Summary Comparison Table: Lawyer vs DIY Prenup

What Makes a Good Prenup in 2025?

A well-structured prenup is about clarity, not control. Whether you use a lawyer or try to draft one yourself, a good agreement should:

• Be clear and specific: Ambiguity invites legal challenges.

• Feel mutual: Courts often reject overly one-sided contracts.

• Follow your state’s legal process: Laws vary on timing, disclosure, and representation.

• Show both parties had time and legal counsel: Prenups signed under pressure or without adequate information are often thrown out.

Lawyer vs DIY Prenup: Detailed Comparison

Cost & Time

• DIY: You might pay nothing upfront, but mistakes are expensive later. If your agreement is invalidated, you’re left with default divorce laws.

• Lawyer: Costs typically range from $1,500 to over $5,000, depending on complexity and location. Worth it for complex situations.

• AI Prenup Advisor: A Free tool that saves time by helping you organize your thoughts, understand your options, and avoid common missteps before hiring legal help.

Legal Enforceability

• DIY: Most self-made prenups fail to meet legal standards. Missing disclosures, vague clauses, or a lack of independent review are common reasons.

• Lawyer: An experienced attorney knows how to draft enforceable agreements that stand up in court.

• AI Prenup Advisor: Helps you flag common legal pitfalls, understand what clauses matter, and what your state law requires.

Some couples use a hybrid approach. Here’s how one business owner used a tool to prep and then worked with a lawyer.

Customization & Complexity

• DIY: Templates are rarely built for situations involving business ownership, inherited wealth, or blended families.

• Lawyer: Can address specific needs, including ownership interests, future earnings, or separate property protection.

• AI Prenup Advisor: Asks the same key questions a lawyer would and generates a custom summary of what you should bring to legal counsel.

Emotional and Relationship Dynamics

• DIY: One-sided attempts can create tension and mistrust.

• Lawyer: A neutral third party can help navigate sensitive conversations, but legal meetings often feel formal and high-stakes.

• AI Prenup Advisor: Offers a lower-pressure way to start the conversation, gather facts, and make the discussion more about protection than paranoia.
