The five PSL/ASL execution mistakes that cost PI providers the most money

Every personal injury provider has felt it: the lien that should have paid in 60 days drags out for nine months because a single field on the patient signature lien was incomplete. After reviewing roughly 1,200 PSL and ASL executions across 40 provider groups in Q1 2026, our revenue operations team found that a small set of recurring mistakes accounted for the overwhelming majority of preventable delays. None of them were dramatic — and none of them required new staff to fix.

1. Missing or undated attorney signature. Almost a quarter of the delayed liens we audited had no date next to the attorney's signature, or were missing the attorney signature entirely on the assignment portion. Most funders and defense carriers reject these on first review and send the entire packet back through fax purgatory. A pre-routing checklist that simply blocks the lien from being filed without both fields populated removes this category of error completely.

2. Patient signature without a witness. Many states allow patient-only signatures on a treatment lien, but most factoring companies still require a witness signature for clean assignment. If you ever expect to sell the receivable, build witness capture into your intake template once and forget about it. The patient is already in your office — having a front-desk staffer witness adds about ten seconds.

3. Outdated attorney letter of representation. If the LOR predates the date of loss by more than 90 days, or if it has expired against the attorney's current matter management system, expect questions. Refresh the LOR at the start of treatment and again at any major case milestone (filing of suit, mediation, demand). It's cheap insurance.

4. No balance ledger at execution. A lien signed without a running balance creates ambiguity at settlement. The attorney has nothing concrete to negotiate against, and you end up taking a reduction you didn't have to. Attach an itemized ledger with current charges and projected remaining course of care at the moment the lien is signed, then refresh it monthly.

5. No backup eSign audit trail. Wet signatures still get challenged. Built-in eSign with a full audit trail — IP, timestamp, geolocation, identity verification — eliminates the vast majority of post-settlement disputes about whether the patient actually signed. If your platform doesn't produce a defensible audit log, your liens are weaker than they need to be.

Fixing these five issues — most of which take five minutes per case — typically moves average days-to-payment from 180 down to under 110 across the practices we work with. The work isn't glamorous, but the cash impact is.
