Divorce and money:
the practical facts.

Section 1 · Community property vs equitable distribution

Two different default systems apply across the U.S.:

Your state determines the framework. Within that framework, the specifics depend on your agreement, the judge, and the facts. Most divorces settle before trial; the state system is the default backdrop the settlement is negotiated against.

Section 2 · 401(k) and pensions, QDROs

A Qualified Domestic Relations Order (QDRO) is a court order required to split a 401(k), pension, or similar ERISA-qualified plan without triggering the 10% early-withdrawal penalty^[2]. QDROs are one of the most mishandled financial aspects of divorce.

• Without a QDRO: any direct movement of 401(k) funds to an ex-spouse is a taxable distribution. If the recipient is under 59.5, add the 10% penalty. A multi-thousand-dollar avoidable tax bill.
• With a QDRO: funds transfer tax-free to the ex-spouse's own retirement account (they can choose to keep it deferred or roll to a Roth and pay tax).
• IRAsIndividual Retirement Account (IRA)A personal retirement savings account with tax advantages. Two main types: Traditional (tax now, pay later) and Roth (pay now, tax-free forever).Full definition don't need a QDRO. A "transfer incident to divorce" handles IRA splits, but the divorce decree must specify the arrangement in the exact language the custodian requires. Work with your attorney and both custodians on the paperwork.

Section 3 · Bitcoin in divorce

Self-custodied Bitcoin is nearly impossible for a forensic accountant to find if not disclosed. A seed phraseseed phraseThink of it as the combination to a bank vault that exists only in your head: 12 or 24 specific words in a specific order. Anyone who copies the combination opens the vault. The bank has no copy. There is no locksmith, no reset, no customer service. Lose the words, lose the Bitcoin.Full definition written on paper in a fire safe leaves no paper trail, no bank record, no brokerage statement.

This does not mean you can hide it. Divorce courts require full financial disclosure under penalty of perjury. Hiding assets discovered after the fact is grounds for the court to reopen the judgment, award the entire hidden asset to the other spouse, and sanction the non-disclosing party^[3]. Forensic firms increasingly use blockchainblockchainImagine a spreadsheet that tracks every Bitcoin transaction ever made, copied identically on thousands of computers worldwide. To rewrite a past entry, an attacker would have to change it on a majority of those computers at the same instant. That is mathematically impractical. That is why Bitcoin transactions cannot be undone.Full definition analysis to find links from exchange accounts forward.

Marital vs separate Bitcoin:

• Bitcoin purchased during the marriage with marital funds is typically marital property.
• Bitcoin purchased before the marriage may be separate property, but appreciation during the marriage is frequently treated as partly marital (state-dependent).
• If separate Bitcoin was ever commingled with marital funds (deposited into a joint account, used for joint expenses), the separate-property character may be lost.

Section 4 · Practical steps

• Document everything before you file. Statements for every account, the last three years of tax returns, deeds, titles, life insurance policies, loan documents, credit reports. Once the process starts, the other side's cooperation may disappear.
• Know every account that exists. Many divorces uncover accounts the other spouse was unaware of. Make a comprehensive list yourself before anyone has reason to obscure.
• Open your own credit card if you don't have one. A divorced person with no individual credit history has a painful rebuilding process. Start before the divorce.
• Distinguish joint from separate. The labels on accounts tell part of the story; the state-law treatment tells the rest.
• Consider tax implications when dividing. $100K in a Roth IRA is not equal to $100K in a Traditional 401(k). Roth is worth more per dollar because the tax has already been paid. Skilled negotiators account for this; unskilled ones trade dollar-for-dollar and one side comes out ahead by 20–30%.
• Update beneficiarybeneficiaryThe person or entity you name to receive an account or insurance policy when you die. designations after finalization. Beneficiary designations override wills. If your ex-spouse remains the named beneficiary on a 401(k) or life insurance policy, they get the money regardless of what your will says.

Section 5 · Divorcing after 50: different rules apply

A divorce near retirement is a different animal: there are fewer earning years left to rebuild, and three sets of federal rules (Social Security, Medicare, pensions) quietly turn on decisions made during the settlement. Four things to know before signing anything:

• You may be able to claim Social Security on your ex's record. If the marriage lasted 10 years or more, you are currently unmarried, and you are 62 or older, you can receive up to 50% of your ex-spouse's full retirement benefit, and it neither reduces their check nor notifies them^[6]. You get the larger of your own benefit or the ex-spouse amount, not both. If the divorce was finalized at least 2 years ago, you can claim even if your ex has not filed yet. The 10-year line is a cliff: a marriage ending at 9 years and 11 months gets nothing, which is worth knowing before the divorce date is set.
• Survivor benefits survive the divorce too. If your ex-spouse dies, a 10-year marriage entitles you to survivor benefits of up to 100% of what they were receiving, and remarrying after age 60 does not take it away^[6]. See Social Security strategy for how these interact with your own claiming age.
• Medicare premiums look at your married income unless you object. IRMAAIncome-Related Monthly Adjustment Amount (IRMAA)A Medicare surcharge added to your monthly premium if your income exceeds certain thresholds.Full definition surcharges are set by your tax return from 2 years ago, when you were filing jointly. Divorce is a qualifying life-changing event: file form SSASocial Security Administration (SSA)The federal agency that manages Social Security retirement, disability, and survivor benefit programs.-44 to have the surcharge recalculated on your new, single income instead of waiting out the lookback^[7]. Details at the IRMAA page.
• Pension survivor elections are settlement items, not afterthoughts. A private pension's survivor annuity for a former spouse generally exists only if the QDRO says so, and the elections are effectively irrevocable once benefits start^[4]. The same settlement logic applies to the house: keeping an illiquid home while giving up retirement accounts trades income you will need for equity you can't spend without moving.
