Neptune vs Walzer Melcher: Prenups in Los Angeles, Compared
For Los Angeles couples planning a wedding, California's community property rules turn the prenup conversation into a real decision: keep the default 50/50 split of marital earnings, or set your own terms before the wedding. Two options come up in serious LA prenup searches: Walzer Melcher LLP, a Band 1 Chambers high net worth family law boutique in Woodland Hills, and Neptune, a flat-fee prenup concierge that pairs each partner with an independent California family law attorney for $5,000 all-in. The price gap is structural: Neptune uses AI to handle the intake, financial disclosure, and decision mapping that traditionally consume attorney hours, so each side's licensed family law attorney spends their time on drafting, negotiation, and judgment. This is how they actually compare.
Key takeaways
- Neptune delivers an enforceable California prenup for $5,000 flat, with one independent California family law attorney per partner, AI-managed financial disclosure, and California's 7-day rule built into the schedule.
- Walzer Melcher LLP is a Band 1 Chambers high net worth family law boutique in Woodland Hills, recognized by Best Lawyers 2026 as a Best Family Law Firm in California. The firm bills hourly. Couple's prenup engagements at top LA HNW boutiques in this tier typically run $30,000 to $100,000+ all-in based on market data, with each side hiring its own firm.
- The flat fee is lower at Neptune because AI handles the non-attorney work that traditionally inflates legal bills, not because attorney involvement is reduced. Each partner works directly with their own California family law attorney for drafting and negotiation.
- California's prenup enforceability bar rests on three things: voluntariness, the 7-day rule under Family Code §1615(c)(2), and independent counsel for any spousal support provision under Family Code §1612(c). Neptune is built around all three.
- For dual-career LA couples with real assets, vesting equity, or an inheritance in the picture, Neptune is the natural fit. For founders with complex multi-entity equity, entertainment industry deal structures, athletes, or contested negotiations, Walzer Melcher's bench is the right call.
Neptune vs Walzer Melcher: What Sets Them Apart
1. What do they do?
Neptune: A flat-fee prenup concierge for couples. Each partner is paired with an independent California family law attorney from Neptune's vetted network. AI handles the intake and financial disclosure work that traditionally drives up legal bills, and each attorney handles drafting, negotiation, and review for their client. California's 7-day rule is built into the signing schedule by default. Designed for couples who want both partners properly represented under California law without paying for two LA boutiques on parallel hourly meters. Neptune is built to be the long-term partner across the legal and financial admin that comes with partnership: prenup before the wedding, estate plan after the wedding, joint taxes, and updates as life changes.
Walzer Melcher LLP: A high-net-worth family law boutique in Woodland Hills. The firm is Chambers Band 1-ranked for HNW family law and recognized by Best Lawyers 2026 as a Best Family Law Firm in California. Named partners include Peter M. Walzer, Christopher C. Melcher, and Steven K. Yoda. Christopher Melcher authored the LexisNexis treatise on California premarital agreements. The firm covers premarital and postmarital agreements, divorce, custody, complex HNW matrimonial litigation, business owner divorce, professional athlete divorce, celebrity divorce, and international family law.
2. Are lawyers involved?
Neptune: Yes. Each partner gets their own independent California family law attorney from Neptune's vetted network. Both attorneys handle drafting, negotiation, and the discussion of contested terms. The AI handles intake, asset gathering, and decision tracking between partners; the legal work is done by licensed California family law attorneys.
Walzer Melcher: Yes. The firm represents one party in the negotiation. The other partner is expected to retain independent counsel, typically another LA family law boutique. Engagements are partner-led, including by Peter Walzer, Christopher Melcher, or Steven Yoda, depending on staffing.
3. How is the process structured?
Neptune: AI-led intake, then direct work with each partner's attorney. Both partners use the AI together to surface assets, income, separate property, business interests, and the terms each side wants (spousal support provisions, sunset clauses, equity treatment, premarital appreciation). By the time the attorneys engage, the discovery and disclosure work is done. Each attorney then handles drafting and negotiation for their client, with the California 7-day rule built into the signing schedule. Most couples finish in a few weeks to a couple of months, depending on complexity and alignment. The timeline is compressed because the intake is, not because attorney involvement is.
Walzer Melcher: Traditional HNW family law firm process. Initial consultation, strategy meeting, drafting, exchange of disclosure between firms, negotiation, revisions, the 7-day review window, and execution. Timelines depend on alignment between partners and how the other side's firm responds. Six to twelve weeks is common for a clean engagement; longer for contested negotiations.
4. What does it cost?
Neptune: $5,000 flat, all-in. That covers both partners, both independent California family law attorneys, AI-led intake, financial disclosure, drafting, negotiation, and execution. No hourly meter. The lower price is structural: AI handles the work that traditionally consumes attorney hours, so each side's attorney concentrates on drafting and legal judgment.
Walzer Melcher: Hourly. The firm does not publish flat fees for prenups. Based on broader LA market data for top HNW family law boutiques, senior partner hourly rates generally run $600 to $1,200+ per hour, and a clean prenup engagement at this tier typically runs $15,000 to $25,000 per side, scaling to $50,000+ per side for complex matters. Because each side hires its own firm, the total couple cost commonly lands in the $30,000 to $100,000+ range. These figures are market estimates, not Walzer Melcher published prices.
5. Who is it built for?
Neptune: Dual-career couples at top companies who have real assets to plan around together. Engineers, physicians, consultants, lawyers, finance professionals, and founders. Often, with complex finances, vesting equity or an inheritance is in the picture. Most are in their late 20s through 40s, somewhere on the arc from pre-marriage to first kids. The right fit for the standard LA prenup situation: a couple who wants both partners independently represented without two parallel hourly meters.
Walzer Melcher: High net worth couples and families. Founders with significant vesting equity or a near-term liquidity event, entertainment industry talent with complex backend deals, professional athletes, inherited family wealth with multi-generational trust interests, or any situation where one or both sides expect a contested negotiation that needs trial-grade family law counsel.

Bottom Line: Which Fits Your Situation?
For a dual-career LA couple with two professional incomes, a primary residence, retirement and brokerage accounts, vesting equity, or an inheritance in the picture, Neptune is built for the situation. Each partner gets an independent California family law attorney, the 7-day rule is in the schedule by default, AI handles the intake and disclosure work that traditionally consumes attorney hours, and the price is fixed before the engagement starts. The flat fee is structurally lower than parallel hourly firms because AI does the non-attorney work, not because attorney involvement is cut.
For a founder with significant vesting equity and a near-term liquidity event, an entertainment industry client with complex backend deal structures, a professional athlete, a family with multi-generational trust interests, or a couple expecting a contested negotiation, Walzer Melcher's bench is the right call. The work requires that level of family law specialization.
Plenty of LA couples use Neptune as their long-term partner for the legal and financial admin of partnership, from prenup through estate plan through ongoing updates, and engage a traditional HNW family law boutique only when the situation calls for that specific level of complexity or contested negotiation.

Frequently asked questions
Is a Neptune prenup enforceable in California?
Yes, when executed correctly. California's enforceability bar comes from the Uniform Premarital Agreement Act and Family Code §1615 and §1612: the agreement must be voluntary, the final version must be presented at least seven calendar days before signing under §1615(c)(2), and any spousal support provision requires the party against whom enforcement is sought to have been represented by independent counsel under §1612(c). Neptune is built around all three.
What is California's community property default, and what does a prenup change?
California is a community property state. Without a prenup, income and assets acquired by either spouse during the marriage are generally treated as jointly owned and split 50/50 in a divorce. Separate property (assets brought in, or received as gift or inheritance during the marriage) generally stays separate, but the lines blur quickly without documentation, especially with vesting equity or commingled accounts. A prenup is how a couple sets their own rules in writing before the wedding instead of relying on the default.
Can Neptune handle a prenup if one partner has startup equity?
Often, yes. For a defined cap table position with standard vesting and no unusual investor rights, Neptune's California family law attorneys can address the equity in a standard prenup. For founders with multiple entity structures, significant outside investors with unusual rights, or a near-term liquidity event, Neptune will be upfront about scope and can refer to a traditional HNW family law boutique like Walzer Melcher.
Why is Neptune's $5,000 fee lower than Walzer Melcher's $30,000 to $100,000+ for a comparable couple's prenup?
The price difference reflects how each model uses attorney time. At a traditional LA HNW boutique, both sides hire their own firm, and the attorneys spend meaningful hours on intake, disclosure, asset valuation, and document organization, all of which are billable. At Neptune, AI handles that work upfront for both partners, so each side's attorney concentrates on legal judgment: drafting, negotiation, customization, and review. The flat fee is lower because the attorney is more efficient, not because attorney involvement is reduced. Every Neptune California prenup is still drafted, negotiated, and reviewed by a licensed California family law attorney from the vetted network.
Does my partner need to use Neptune too?
No, in the sense that California's enforceability rules support each partner having their own counsel rather than sharing one. Neptune assigns each partner their own independent California family law attorney from the vetted network by default. If one partner prefers to bring their own outside counsel from a firm of their choosing, that works as well, and Neptune can coordinate the disclosure and 7-day timing with that outside attorney.
Is there any way around the 7-day rule?
No, and there is no reason to want one. California Family Code §1615(c)(2) requires the final version of the agreement to be presented to the party against whom enforcement is sought at least seven calendar days before signing, whether or not the party has counsel. The rule exists to support enforceability. Any process that skips it creates an enforceability problem the couple inherits.
Is independent counsel required for a California prenup?
For the agreement itself, California allows a party to proceed without independent counsel, but the unrepresented party must receive specific written advisement of the rights they are giving up and must acknowledge that advisement in writing, per Family Code §1615(c). For any provision waiving or limiting spousal support, independent counsel is required under §1612(c). Neptune's default is to give each partner their own independent California family law attorney from the vetted network, which clears both bars.
