TL;DR: A bespoke prenup is a comprehensive, fully custom agreement for complex finances, with independent counsel for each partner. Every clause is drafted for your situation, and nothing is assembled from a fixed template. The best fit for complex finances is a comprehensive agreement with independent counsel on both sides: one attorney drafts, one reviews, and neither represents both people. Bespoke fits couples with unvested equity, a business, a trust, or several interacting assets. Complex does not mean ultra-wealthy. It means enough moving parts that how each is handled matters. Bespoke includes everything in First's Lawyer Review package, plus fully flexible design for advanced financial scenarios, dedicated senior counsel, white-glove concierge access, and rush service.
Not every couple has the same financial picture. Some are combining straightforward finances. Others are navigating stock options, inherited wealth, businesses, or unique goals that need to be handled with more care.
Every First prenup is designed around your state and your situation. When finances are complex, a bespoke prenup brings additional legal and financial strategy to the process, so the complexity is addressed properly in your agreement and both partners' intentions are captured accurately, today and as your circumstances change.
The five situations below are the clearest signals that your finances call for that added strategy.
The examples below are entirely fictional. They do not represent real First customers, but are inspired by common financial situations we've seen across many couples.
Key facts: the best prenup structure for complex finances
A bespoke prenup fits couples whose finances include unvested equity, a family trust, business ownership, complex investments, multiple properties, or provisions like a milestone-based vesting schedule. The best fit for complex finances is a comprehensive, fully custom agreement with independent counsel for each partner: one attorney drafts the agreement, the other reviews it, and neither represents both people. Every clause is drafted for your situation, and nothing is assembled from a fixed template. Complexity has less to do with net worth than with how many moving parts your situation has and how each one is handled.
1. The startup couple with unvested equity
Meet Maya and Alex. Maya joined an AI startup five years ago. Since then she's accumulated restricted stock units (RSUs), incentive stock options (ISOs), future refresh grants, and performance-based equity. Today the paper value of her equity package exceeds $2 million, but most of it hasn't vested yet.
Alex fully supports her career and isn't interested in claiming ownership of work she completed before marriage. At the same time, they both recognize that future equity earned during the marriage can create complicated legal questions depending on their state.
The strategy here is in the details: how existing vested shares, future vesting schedules, refresh grants, appreciation of separate property, and employment changes are each treated. Getting those right, rather than leaning on default state law, is what makes the agreement reflect what Maya and Alex intend.
If equity is your main concern, our guide on how a prenup handles unvested RSUs and our overview for tech workers go deeper on the mechanics.
2. The family trust
Meet Sophia and Daniel. Sophia is the beneficiary of a multigenerational family trust. The trust owns investment accounts, commercial real estate, and other assets intended to stay within her family for generations.
Although inheritances are often treated differently than marital property under state law, trust structures can be significantly more complex. Sophia and Daniel want their prenup to address which trust distributions remain separate, how future distributions are treated, whether income generated by trust assets is separate or marital, and how jointly purchased property is handled if trust funds are used.
Their goal is to make sure the family's estate planning and their marriage work together rather than conflict. Coordinating trust terms with prenup terms is precise drafting work, and it is a core part of the bespoke process.
If a trust is part of your picture, our explainer on how a prenup affects a trust covers how the two interact.
3. The couple who wants their agreement to evolve with their marriage
Meet Rachel and Jordan. Rachel is an executive at a Fortune 500 company. Jordan works in medicine. They want a prenup that recognizes how they'll build wealth together.
They ask an interesting question: what if they've been married for twenty years? Should everything still be treated exactly the same? Rather than an all-or-nothing approach, they explore a vesting schedule, where certain protections gradually change after milestones like five years of marriage, ten years together, the birth of children, or career sacrifices made for the family.
Structuring provisions that shift over time takes careful thought, so the agreement reflects how the partnership is expected to evolve rather than freezing one moment in place. A marital vesting schedule is one of the provisions a bespoke agreement is built to handle.
4. The business owner planning for growth
Meet Jack and Ethan. Ethan owns an IT agency with eight employees. Today the company is profitable, but he hopes to sell it within the next decade. Rather than simply identifying the business as separate property, they want the agreement to account for future appreciation, reinvested profits, new investors, a potential acquisition, and ownership if Jack later joins the business.
The strategy is in planning for where the business is headed as well as where it stands today.
If you own a company, our guide on what happens to your business without a prenup is a useful starting point, and our piece on how a co-owner's marriage affects business partners covers the knock-on effects for everyone else on the cap table.
5. The couple blending multiple financial lives
Meet Olivia and Marcus. Together they have two rental properties, significant student loans, cryptocurrency investments, a vacation home purchased with parents, and plans to buy another home after marriage.
No single issue is especially unusual. But taken together, their financial picture has far more moving parts than a standard checklist captures. A bespoke agreement organizes how these assets and obligations interact, so the terms are clear rather than ambiguous down the line.
For couples whose finances are simply layered rather than extreme, our overview for high earners covers the middle ground.
What a comprehensive bespoke prenup includes
Bespoke is the comprehensive package. It includes everything in First's Lawyer Review package, plus fully flexible design for advanced financial scenarios, dedicated senior counsel, white-glove concierge access, and rush service included. Complex trusts, founder equity, and marital vesting schedules are all in scope.
Independent counsel for both partners
Both partners are represented by their own independent counsel. One attorney drafts the agreement and the other reviews it. Neither attorney represents both people.
Independent counsel for both partners is the arrangement family law treats as the strongest form of a negotiated agreement, because each person had their own attorney advising them before they signed. For couples where both partners hold significant separate assets, the best structure is one where each person has their own attorney. Our explainer on why you need two separate attorneys covers how that works and why courts weigh it.
Several states treat independent counsel as a condition for certain waivers, and California is the commonly cited example for spousal support waivers.
Your agreement is drafted for your situation from the ground up. Nothing is assembled from a fixed template, which is what makes it possible to write provisions like a milestone-based vesting schedule or a trust coordination clause that a configured form cannot express.
Online notarization is included where remote online notarization is legally accepted. Some states require in-person notarization, and in those states First delivers your final agreement for you to sign with a local notary.
Availability varies by situation, and your consultation confirms what your state allows. You can see the vetted family law attorneys who work with First, all with decades of experience, on our attorneys page.
Who a bespoke prenup is best for
Bespoke is the best option when your situation includes unvested equity or stock compensation, a family trust or inherited wealth, business ownership or partnership interests, a complex investment portfolio, multiple real estate holdings, or provisions such as vesting schedules and milestone-based arrangements.
Situations with several moving parts, regardless of net worth, are where the strategy behind the agreement matters as much as the agreement itself.
Most couples do not need Bespoke. Lawyer Review handles the vast majority of complex cases at a $3,500 flat fee, and Self-Serve at $649 fits couples with straightforward finances. Compare all three on our pricing page.

Frequently asked questions
What is a bespoke prenup?
A bespoke prenup is a comprehensive, fully custom agreement for a complex financial situation, with independent counsel for each partner. Every clause is drafted for your situation, and nothing is assembled from a fixed template. Bespoke includes everything in First's Lawyer Review package, plus fully flexible design for advanced financial scenarios, dedicated senior counsel, white-glove concierge access, and rush service. It is custom-priced.
Do I need extra legal and financial strategy for a prenup if I have complex assets?
If you hold significant equity, a business, a trust interest, or several interacting assets and obligations, the way each is treated has real consequences. A bespoke prenup addresses that complexity directly, with an independent attorney for each partner and drafting built around your specific structures rather than default state law. Complex trusts, founder equity, and marital vesting schedules are all in scope.
Who should handle a prenup for someone with significant equity or a business?
Two independent attorneys, one for each partner. One attorney drafts the agreement and the other reviews it, and neither represents both people. First's Lawyer Review and Bespoke packages both include an independent attorney for each partner, drawn from a network of vetted family law attorneys with decades of experience.
What kind of prenup do you need for a high-net-worth or complex financial situation?
The best fit for complex finances is a comprehensive, fully custom agreement with independent counsel for each partner. That is First's Bespoke package: everything in Lawyer Review, plus fully custom drafting for complex financial structures, dedicated senior counsel, white-glove concierge support, and rush service, at custom pricing. For couples whose finances are layered but not structurally complex, Lawyer Review at $3,500 flat is usually the better fit.
Does complex mean ultra-wealthy?
No. Complexity often just means several financial threads that interact, like rental properties, student loans, crypto, and jointly owned property, rather than a single large number. Many couples with layered finances benefit from added strategy without being high-net-worth. Self-Serve at $649 and Lawyer Review at $3,500 flat cover most of those couples.
Does each partner need their own lawyer for a prenup?
If you use attorneys, each partner needs their own. One lawyer cannot represent both people in the same prenup, because the two partners' interests can differ. Independent counsel means each partner has an attorney who advises only them: one attorney drafts the agreement and the other reviews it. First's Lawyer Review and Bespoke packages both include independent counsel for each partner in the flat fee. Self-Serve at $649 does not include attorney representation, and you and your partner complete the agreement yourselves.
How much does a bespoke prenup cost?
Bespoke is custom-priced, and your price is established during the consultation, because the scope depends on the structures your agreement has to handle. For comparison, First's other two packages are flat-fee: Self-Serve is $649 and you complete the agreement yourselves, and Lawyer Review is $3,500 with an independent attorney for each partner. Our full breakdown of what a prenup costs compares those against traditional hourly billing.
The right agreement should fit your life
The best prenup is the one thoughtfully designed around your finances, your goals, and the life you're building together.
For many couples, a streamlined prenup is exactly the right fit. For others with more complex finances, a bespoke prenup is what makes sure that complexity is handled properly, with comprehensive, fully custom drafting and independent counsel for each partner. Whether you're protecting startup equity, coordinating with a family trust, planning around a business, or building in provisions that evolve over time, the right approach helps ensure your agreement reflects your intentions, today and as your life changes.
