What to Do When a Broker Denies Your Detention Claim

Most detention denials are administrative rather than final. They come from a billing clerk applying a rule, not from anyone deciding the merits, and a large share of them reverse on resubmission to the right department.

But two of the six common denials genuinely end the matter, and the fastest way to lose a recoverable claim is to spend a week arguing an unrecoverable one. So sort the denial before you write anything.

Sort the denial first

The last row is the one carriers concede too easily. Many brokers pay detention only after the shipper reimburses them, and pass the refusal straight through. Whether they’re entitled to do that turns on whether contingent payment language is actually in your rate confirmation. Frequently it isn’t, and the broker is the party you contracted with regardless of what the shipper decides.

Today: send it to someone who can actually pay it

Your dispatcher contact has no authority over accessorial disputes. Resubmitting to the same person usually produces the same answer.

Send the packet to the broker’s accounts payable or claims address instead, with the rate confirmation attached and the detention clause highlighted. Reference the load number in the subject line and state the amount. Denials caused by missing documentation resolve at a reasonable rate at this stage, and it costs you fifteen minutes.

This week: a demand letter

If AP declines or ignores you, a formal demand letter is the next step, and it resolves a meaningful share of disputes before anything external happens.

Send it by certified mail and by email on the same day. Keep it to one page:

• Load number, dates, origin and destination
• The specific clause from the rate confirmation, quoted
• The dwell timeline with check-in and release times
• The amount owed
• A cure period, commonly fifteen days, with a date
• What you’ll do next if it passes

That last line is what gives the letter force, and it should be true. If you’re not prepared to file a bond claim or report the broker, don’t say you will.

If the broker holds US authority, the bond is your real leverage

Any broker licensed by FMCSA must maintain $75,000 in financial security, either a BMC-84 surety bond or a BMC-85 trust. An unpaid carrier can file a claim against it.

What changed on January 16, 2026 is the enforcement. If a broker’s available security drops below $75,000 and isn’t replenished within seven business days of FMCSA’s notice, FMCSA suspends their operating authority. The old rule gave thirty days. Suspensions are posted publicly.

This cuts both ways as a screening tool. You can check a broker’s financial security filing before you haul, which is a better use of the system than discovering the problem afterward.

If the broker is Canadian, you don’t have that

There is no Canadian equivalent. No federal freight broker licensing, registration, or bonding requirement exists, and outside Ontario’s trust account obligation and Quebec’s registration requirement, brokerage is unregulated. There’s no bond to claim against and no regulator to complain to about non-payment — the full picture on the Canadian side is worth reading before you rely on any of it.

What you have instead is a contract claim, and one escalation step worth knowing. The broker-carrier agreement template published by a Canadian brokers’ association lets the carrier seek payment from the shipper directly after giving the broker twenty business days’ written notice. If that language is in your agreement, it’s a real lever and it costs nothing but a letter.

Check the reverse, too. Some shipper-side agreements have the carrier certify that it will look solely to the broker and has no claim against the shipper. Which of those you signed decides whether the step above exists for you.

The practical consequence is that reputation channels and credit reporting carry more weight in Canada than they should have to, because they’re most of what’s available.

Reputation channels work, and they’re a one-way door

Reporting a non-paying broker to Carrier411, FreightGuard, or the BBB is effective, particularly against smaller brokers, because it affects their ability to onboard carriers at all. It often produces payment faster than anything else on this list.

Two things not to do

Don’t hold the freight. Whatever you may have heard about carrier liens, check your own agreement first. Knight-Swift’s says flatly that the carrier has no right to assert any lien on property transported under it. Where that clause is in force there is nothing to argue about, and withholding cargo over a disputed accessorial puts you badly in the wrong on a much larger sum than the detention.

Don’t assume your factoring agreement is neutral. If you factor with recourse, an unpaid invoice typically gets charged back to you after a set period, and disputed accessorials are commonly excluded from non-recourse protection entirely. That means an unresolved detention claim can become your problem twice. Read your agreement’s treatment of accessorials before you assume the invoice is off your books.

When to walk away

Before assuming litigation is available, check where your agreement sends disputes. The Canadian association template makes arbitration the sole recourse, under ADR Institute of Ontario rules, with Ontario as the venue and an eighteen-month limit from delivery. Knight-Swift’s sends everything to courts in Maricopa County, Arizona. Neither leaves you free to file wherever is convenient, and small claims may not be available at all.

Wherever it lands, litigation is real leverage above a certain threshold and pure loss below it. The filing time, the appearance, and the collection effort afterward are not worth it for a two or three hundred dollar detention charge, no matter how right you are.

Walk away when: no notice was sent, the rate con had no terms, the submission window closed through your own delay, or the amount is smaller than the hours you’d spend — which is sound arithmetic more often than carriers admit.

Then treat the write-off as information. Three denials from the same broker for the same reason is a rate confirmation problem or a process problem, and neither gets fixed by escalating the fourth one harder.

What to do next

Today, resubmit to accounts payable with the full packet. If nothing moves in five business days, send the demand letter with a fifteen-day cure date. If that passes and the broker holds US authority, check their bond filing and decide whether to claim. If they’re Canadian, decide whether the relationship is worth more than the credit report.

And keep a simple tally of which brokers deny, for what reason, and how often. That record is what turns individual arguments into a decision about who you haul for, which is the only version of this that scales.

Catching the wait as it happens, so the notice goes out on time and the packet is already built when the denial arrives, is the part that’s hard to do by hand. That’s why we built DwellWatch.
