For software engineers with equity compensation

A prenup built around equity, not just salary

For software engineers, a large share of total compensation is equity that vests over time, sometimes across more than one employer. RSUs, options, and prior-employer grants raise questions standard prenup templates do not address. Neptune connects you with two independent attorneys and a guided process designed for complex equity.

Why software engineers use prenups

Equity compensation makes prenups distinctly useful

At top tech companies, equity is often 30 to 60% of total compensation. That mix creates planning questions a purely salaried earner never faces.

  • 1

    The vesting-during-marriage problem

    The common path: you take an offer with a four-year grant, get engaged in year 1 or 2, marry, and the bulk of the equity vests during the marriage. Without a prenup, in California the vested portion may default to community property.

  • 2

    Public-company RSUs

    RSUs at public companies vest on a schedule, become liquid at vesting, and are taxed as ordinary income at vest. A prenup can help clarify how shares vesting during the marriage are characterized.

  • 3

    Private-company options and pre-IPO shares

    ISOs, NSOs, and pre-IPO RSUs carry illiquidity risk and the potential for outsized future value. A prenup can address how illiquid equity and any future liquidity event are treated.

  • 4

    Overlapping annual refreshes

    Most major tech companies issue refresh grants at performance reviews. After several years you may have four or five overlapping four-year schedules running at once, each a potentially distinct asset.

  • 5

    Prior-employer grants and ESPP

    Many engineers carry unvested options or unexercised grants from a previous employer, plus discounted ESPP shares that are easy to overlook. A prenup can catalogue these pre-marital assets so their separate character is documented.

  • 6

    Side projects and future companies

    If you start a side project or company while married, the question of how that interest is treated comes up quickly. A prenup can help address future business interests before they exist.

How Neptune works

From first question to signed agreement

Step 1

Get aligned with guided intake

Answer questions about your finances, equity, and goals as a couple. Neptune’s guided intake helps both partners get clear on what matters before any legal work begins.

  • Talk through equity, debt, and priorities
  • Surface the conversations that matter early
  • Walk in prepared, not starting from a blank page

Step 2

Work with two independent attorneys

Neptune connects each partner with a separate, licensed attorney for a free consultation. One attorney represents you; a different attorney represents your partner. No payment is required until you decide to move forward.

  • A separate attorney for each partner
  • Free consultations before you commit
  • Independent counsel supports a fair agreement

Step 3

Review, finalize, and sign

Your drafting attorney prepares an agreement based on your situation, and your partner’s reviewing attorney reviews it with them independently. Turnaround is typically around 3 to 4 weeks when both partners use Neptune attorneys, though this can vary.

Common questions from software engineers

Do equity refreshes count as separate property?

New grants issued after the marriage are generally treated as separate property only if your prenup addresses future equity grants clearly. Without that language, state-law defaults apply, and in community property states grants earned during the marriage may be treated as community property. Neptune’s guided intake surfaces your refresh history so your attorney can draft language that reflects your intentions.

What about options I never exercised from a prior employer?

Unvested or unexercised options from a prior employer can still pay out someday. A prenup can document these as pre-marital assets and address how any future value is characterized. Your attorney can review your grant agreements and what documentation is appropriate.

What if my company IPOs during the marriage?

If a liquidity event happens while you are married, shares you held before marriage may be treated differently from shares granted during the marriage, and appreciation during the marriage is an active question under state law. A prenup can help clarify which portion of any proceeds is treated as separate versus marital.

My partner does not have equity comp. Does that change things?

It is common for one partner to hold most of the equity. A prenup lets both partners decide together how that equity, and any future growth, is treated, rather than leaving it to state-law defaults. Each partner works with their own independent attorney, which supports a fair, well-structured agreement.

What does Neptune cost and how long does it take?

Neptune’s prenup is a flat fee of $5,000 per couple, covering two independent attorneys: $3,000 for the drafting attorney and $2,000 for the reviewing attorney. Rush pricing applies when the wedding is within 45 days, and complexity factors may affect the final fee. Turnaround is typically around 3 to 4 weeks when both partners use Neptune attorneys.
