Divorce and the Annexon Biosciences 401(k) Retirement Plan: Understanding Your QDRO Options

If you or your spouse has an account in the Annexon Biosciences 401(k) Retirement Plan and you’re going through a divorce, it’s essential to know how retirement assets are legally and properly divided. A Qualified Domestic Relations Order (QDRO) is the only way a retirement plan like this one—sponsored by Annexon, Inc.—can legally pay out a portion of the account to a non-employee spouse. Without a QDRO, even if your divorce decree gives you rights to part of the account, the plan administrator cannot make a distribution to you.

401(k) plans have very specific rules, and the Annexon Biosciences 401(k) Retirement Plan is no different. Drafting the QDRO correctly the first time is crucial, especially when you factor in issues like loan balances, Roth contributions, and vesting schedules. Let’s break this down and explore how to divide this particular plan properly during a divorce.

Here’s what we know about this retirement plan:

• Plan Name: Annexon Biosciences 401(k) Retirement Plan
• Sponsor: Annexon, Inc.
• Plan Address: 1400 Sierra Point Parkway, Building C, 2nd Floor
• Industry: General Business
• Organization Type: Corporation
• Plan Number: Unknown (required for your QDRO submission—contact plan administrator to obtain)
• Employer Identification Number (EIN): Unknown (also required—your attorney or the plan administrator can help you get this)
• Status: Active

Since this plan is active and governed under federal ERISA law, a QDRO is the correct mechanism to divide these assets during divorce. But before you move forward with a QDRO, there are some specific 401(k)-related issues to consider.

Since Annexon, Inc. is a corporation in the general business sector, it likely uses a third-party administrator (TPA) to manage its 401(k) benefits. Each TPA has its own process, including documentation requirements, timelines for review, and pre-approval options. Failure to tailor your QDRO to that process can cause delays or rejections.

At PeacockQDROs, we’ve worked with all major TPAs. We don’t just draft your QDRO—we follow it through from start to finish. We’ll get the document preapproved (if applicable), file it with the court, and work with the plan administrator until it’s implemented.

Some plans won’t even review your QDRO until it’s been court-certified. Others require very specific formatting. Get it wrong, and you could wait months before finding out there’s a mistake.

To begin the QDRO process for the Annexon Biosciences 401(k) Retirement Plan, you’ll need to provide:

• Full plan name: Annexon Biosciences 401(k) Retirement Plan
• Plan sponsor: Annexon, Inc.
• Plan number and EIN (requested from the plan administrator)
• Participant and alternate payee names and contact information
• Copy of final divorce judgment
• Detailed instructions on how assets should be divided

A QDRO is not a form you can pull off the internet—it must comply with plan-specific rules and ERISA guidelines to be accepted. That’s why experienced professionals matter.

We’ve seen just about every QDRO mistake in the book. Here are a few you especially want to avoid when dividing the Annexon Biosciences 401(k) Retirement Plan:

• Not specifying who pays taxes on distributions
• Failing to define the division method (percentage vs. fixed dollar)
• Omitting provisions for Roth vs. traditional balances
• Using outdated plan names or incorrect plan numbers
• Assuming all contributions are vested
