Step-by-Step Examples

Example 1

California Divorce

$250K home, $150K retirement, $80K investments, $75K debts, CA (50/50).

Net = $480K - $75K = $405K
Each spouse: $202,500
Retirement needs QDRO; home usually sold or bought out

✓ $202,500 each (50/50)

Example 2

NY Equitable

Same assets, 60/40 equitable distribution.

$405K | Higher earner: $243K (60%)
Lower earner: $162K (40%)
NY factors: length of marriage, contributions, custody

✓ $243K / $162K split

Example 3

Significant Disparity

$600K total, $100K debts, 30-year marriage, homemaker vs high earner.

Net = $500K | Court discretion
Long marriages trend toward 50/50 regardless of income
Alimony compensates ongoing income disparity separately

✓ $250K each (long marriage trend

Common Mistakes to Avoid

⚠️

Ignoring tax consequences of different assets

A $200K home equity and $200K in a 401k are NOT equal after taxes. The 401k withdrawal triggers income tax; the home sale may qualify for the $250K/$500K capital gains exclusion. Net-of-tax value matters.

⚠️

Not getting a home appraisal

Agreed value without an appraisal often leaves money on the table. In hot real estate markets, an appraisal may reveal the home is worth $50K-$100K more than estimated.

⚠️

Assuming joint accounts are automatically marital

Separate property (pre-marital funds, inherited money) that has been kept separate is not marital property. Commingling (mixing) separate with marital funds can convert it. Tracing the source of funds is important.

Frequently Asked Questions

How is a home divided in divorce? ▾

Options: sell the home and split proceeds; one spouse buys out the other's equity; defer sale (especially with children) until a future date. The spouse keeping the home must typically refinance into their name alone.

How is a 401k divided in divorce? ▾

Through a Qualified Domestic Relations Order (QDRO) - a court order directing the 401k plan to transfer a portion to the ex-spouse's retirement account. A QDRO avoids the 10% early withdrawal penalty that would apply if you cashed out.

Is separate property divided in divorce? ▾

Generally no. Pre-marital assets, gifts, and inheritances remain separate property. However, appreciation on separate property during marriage is sometimes marital (depends on state), and commingling with marital funds can convert separate to marital property.

What is the marital home buyout? ▾

One spouse pays the other their share of equity to keep the home. Example: home worth $400K with $200K mortgage; equity = $200K; buyout = $100K paid to departing spouse. The remaining spouse must refinance to remove the other from the mortgage.

Do retirement accounts have to be split 50/50? ▾

In community property states: yes for the marital portion. In equitable distribution states: courts have discretion but often split the marital portion equally. The pre-marital portion of a retirement account is typically excluded.
