Custody
Drop trailers: proving custody when nobody signs
Every other handover in a shipment has a moment where two people stand together and one of them signs. A drop trailer does not. Custody moves when a tractor pulls off a yard or a loaded trailer is parked against a fence, and the only record of it is whatever was captured on purpose beforehand.
What is actually missing
A signed delivery receipt does three jobs at once: it fixes a time, it names a person, and it records the condition the goods appeared to be in. Drop and hook removes all three simultaneously, which is why the gap is larger than it looks. The trailer is dropped at 19:40; the receiver's team opens it at 08:15 the next morning; a discrepancy is raised at 09:00. Nothing in that sequence establishes whether the seal was intact at 19:40, who was present, or whether the doors were opened overnight.
The result is not usually theft. It is an unresolvable argument — and an unresolvable argument is settled by whoever has the better paperwork, not by whoever is right.
Substitute the three jobs separately
Because no single document replaces the signature, the record is assembled from parts. Each of these is ordinary; the discipline is doing all of them every time rather than on the loads that later turn out to matter.
| What the signature did | Substitute | Captured by |
|---|---|---|
| Fixed a time | Gate in and gate out timestamps, and the time the equipment was spotted | Gate system, driver record, telematics |
| Named a person | Who authorized the drop, and who was notified that it had happened | Dispatch record, the notification itself |
| Recorded condition | Seal number read and photographed at drop; trailer and door condition | Seal verification at the moment of the drop |
The seal is doing the heaviest work here. It is the only element that carries forward through an unattended period and can still be checked by someone who was not there. A seal number recorded at the drop and verified before the trailer is opened turns an overnight gap into a bounded interval: either the number matches and the doors were not opened, or it does not and you have a defined event to investigate.
The yard is a custody location, not a parking lot
Once a loaded trailer sits on a yard, somebody is holding the goods even though nobody accepted them. Whose custody it is depends on the agreement, and that is worth settling in writing before the first drop rather than after the first loss.
- Who controls access to the yard, and during which hours?
- Is the trailer secured beyond its seal — king pin lock, glad hand lock, nose to a wall or another trailer?
- How often is the yard checked, and is the check recorded when nothing is wrong? A yard check that is only logged when something is found cannot establish when something started.
- Who is called, and how fast, when a seal is found broken or equipment is missing?
- How long may a loaded trailer stand before it must be worked or moved?
The third point is the one most often missed. A routine check with a timestamp and a seal number, recorded whether or not anything is amiss, is what converts “the seal was broken sometime overnight” into “the seal was intact at 02:10 and broken by 05:40”. That narrowing is frequently the difference between a recoverable claim and a shrug.
At the pick-up end
Drop yards are also where equipment is collected, which makes them exposed to the impersonation patterns covered in cargo theft prevention. A trailer standing loaded and sealed on an open yard can be hooked by anyone with a tractor and a plausible manner.
Worth fixing in procedure: no release of a loaded trailer without a verified carrier and driver identity against the dispatch record; the trailer number confirmed against what was actually tendered, not against what the caller says; and any change of collecting carrier confirmed through a known contact rather than the number on the request.
Write it into the agreement
Most drop trailer disputes trace back to an arrangement that was never written down because it started as a favor. Put the basics in the contract or the standard operating procedure: when custody passes, what is recorded at the drop, how long equipment may stand, who checks the yard and how often, and what happens on a seal discrepancy. None of that is onerous, and all of it is evidence later.
See chain of custody in logistics for the underlying record and proof of delivery for how unattended drops are handled on the delivery side. Where a discrepancy is found on opening, it becomes an OS&D report and then potentially a freight claim, and both are easier to run when the interval is narrow.
Keeping the interval narrow
Everything above is a method for shrinking the window in which something unrecorded could have happened. Cargovate's platform models a journey as legs and checkpoints, so a drop, a yard check and a collection are recorded events on the same shipment rather than three entries in three systems that nobody reconciles until there is a claim.
