A notice you cannot prove you mailed is a notice you did not mail, as far as a county clerk, a TDLR investigator, or a judge is concerned. Certified mail exists to make the proof.
The artifacts
- The certified mail receipt with its 20-digit article number, date-stamped at acceptance.
- The return receipt: the PS Form 3811 green card, or the electronic return receipt (ERR) record USPS produces, showing delivery or attempted delivery.
- The letter itself, exactly as mailed, tied to the vehicle file.
Retention
TDLR’s record-keeping rules require facilities to keep records of vehicles and notices for inspection, and the title packet (VTR-265-VSF) requires the notice evidence when you apply. Keep the full set with the vehicle file through the title application and beyond; LienYard keeps a stitched evidence binder per vehicle for 5 years.
