The 401(k) loan trap: paying twice
A 401(k) loan is both an asset and a debt. Judgments that miss this routinely produce an unequal division.
Of all the ways retirement division goes wrong, the 401(k) loan is the quietest. Judgments routinely order the parties to "pay off the loan equally" — language that sounds fair and frequently causes one spouse to pay for the same loan twice.
A 401(k) loan is not a credit card
A loan against a 401(k) is both an asset and a debt — the account holder is the banker and the borrower. Pay off a $5,000 credit card and the card is worth $0. Pay off a $5,000 401(k) loan and the account's vested value just went up by $5,000 — for the account holder.
The double-pay trap, in cents
Albert has $1 in his 401(k) and takes a 20¢ loan during the marriage, leaving 80¢ of value. Split equally, Albert and Betty each receive 40¢ — and that's the correct result. Betty already absorbed her share of the loan when the money came out during marriage; it reduced her half from 50¢ to 40¢.
Now the judgment says the parties will "pay off the loan equally." Betty pays back her "half" — 10¢ — and ends up with 30¢ while Albert ends up with 50¢. Betty just paid for the loan twice.
If the parties genuinely want to share the payoff, the correct structure is different: Betty receives 50¢ coupled with an obligation to reimburse 10¢ — netting her the same 40¢ she was always entitled to.
Timing changes everything
A loan paid off after the date of separation is effectively a new separate property contribution by the account holder. Whether the loan was taken before or after separation, and whether the funds served a community or separate purpose, determines what adjustments the division requires — sometimes including a tracing analysis.
"The parties will equally pay off the 401(k) loan" is not analysis — it's a trap. Classify the loan as a community or separate transaction in the judgment, and let the QDRO attorney determine the mathematical adjustments based on the timing. If your judgment already contains loan language, have it reviewed before money moves.
