Here is a situation that comes up more often than anyone admits: a mass tort settlement is moving toward final approval, and something changes on the counsel side. A co-counsel relationship restructures. A new firm joins the leadership group. The fee-sharing agreement gets renegotiated. Or the settlement terms require updated client authorizations before disbursement can begin.

Whatever the trigger, the result is the same. You need 4,000 claimants (or 8,000, or 12,000) to sign a new document. And you need it done before a hard deadline.

Most firms treat this as a legal task. Draft the new agreement. Email it to the list. Maybe mail a letter. Wait.

That is not a plan. That is a notice campaign. And notice campaigns, on their own, do not hit thresholds.

The Re-Papering Math Nobody Models

Think about what you already know from participation thresholds. Talc settlements have required 95% enrollment. 3M's CMO imposed 86% cure duties. Camp Lejeune documentation rates have been their own grind. In every one of those matters, the firms that hit their numbers treated enrollment as a persistent outreach funnel, not a single mailing.

Co-counsel re-papering is the same math. You have a fixed population. You need a specific percentage to execute a specific document by a specific date. And the response curve looks exactly like every other completion curve: a burst in the first week, a long tail of non-responders, and a final sprint where every additional percentage point costs more than the last.

On a 5,000-claimant re-papering campaign, here is what the curve typically looks like:

If you only planned for one touch, you stopped at 40%. That means 3,000 claimants who already retained you, who already provided documentation, who already waited through years of litigation, are now at risk because nobody built the outreach infrastructure to get their signature on a two-page document.

Why This Is Harder Than It Looks

Re-papering is not just "send the document again." There are several variables that make it operationally distinct from initial enrollment:

Contact decay. If the underlying mass tort has been in litigation for two or three years, a meaningful percentage of your claimant contact information is stale. Phone numbers change. Email addresses bounce. Physical addresses are outdated. You are not reaching the same population you originally signed. You are reaching whatever subset of that population still has the same phone number they had in 2023 or 2024.

Claimant fatigue. These are people who have been waiting for years. They have received dozens of communications. Many have mentally moved on. Getting them to open one more message, read one more document, and take one more action requires a different kind of outreach than the initial "you may be entitled to compensation" hook that brought them in.

Document complexity. A co-counsel agreement is not a simple "click yes" form. It typically requires the claimant to review fee-sharing disclosures, understand what changed, and affirmatively consent. If you are sending this as a PDF attachment to an email, you are asking someone on a phone to download a PDF, print it, sign it, scan it, and send it back. The friction alone will kill 30 to 50% of your potential completions.

Compliance requirements. Depending on the jurisdiction and the nature of the agreement, you may need specific disclosures, specific formatting, or specific acknowledgment language. This is not a place to cut corners. Confirm requirements with your own counsel before launching any campaign.

The Infrastructure You Already Need

If you are running mass tort inventory cases and you do not already have persistent, multi-channel outreach infrastructure, the re-papering problem is just the most visible symptom of a bigger gap. The same infrastructure that gets a claimant to sign a co-counsel agreement is the infrastructure that:

Every one of these is a completion problem. Every one of them follows the same yield curve. And every one of them is solved by the same set of tools: native document signing (so the claimant can execute on their phone without downloading anything), SMS and email delivery (so you can reach them on the channels they actually use), and persistent follow-up cadences that do not stop after one attempt.

What the Winning Firms Do Differently

The firms that consistently hit participation thresholds and re-papering deadlines share three habits:

They model the outreach before the deadline. Before committing to a re-papering timeline, they run the numbers. How many claimants? What is the current contact-information quality? What completion rate do they need? How many touches will it take to get there? They work backward from the deadline and build the cadence before the clock starts.

They own the signing experience. Instead of emailing PDFs or mailing paper, they use native document signing that works on a phone screen. The claimant gets a text, taps a link, reviews the document, signs, and is done. No downloads. No printers. No scanning. This alone can double the conversion rate on the first touch.

They treat non-responders as a separate campaign. After the initial burst, the remaining claimants are not "people who haven't gotten around to it." They are a distinct population with distinct barriers. Some have bad contact info. Some are confused about what changed. Some need a phone call. The firms that hit their numbers segment this population and run targeted outreach, including AI-assisted calls that can answer questions and walk a claimant through the signing process in real time.

The Cost of Getting This Wrong

On a 5,000-claimant inventory with an average recovery of $15,000 per claimant, every 1% of claimants you fail to re-paper represents $750,000 in potential recovery that is stuck. Not lost, necessarily, but stuck. Stuck behind a signature you could not collect. Stuck behind a deadline you did not plan for. Stuck behind an outreach campaign you never built.

At 10% failure, that is $7.5 million in frozen recovery. At a standard contingency, that is $2.5 million in fees your firm cannot collect until someone goes back and finishes the job, usually under worse conditions, with even more contact decay, and at higher per-claimant cost.

The math is not complicated. The infrastructure to solve it is not complicated either. But it has to exist before the deadline arrives, not after.

The Pattern Worth Recognizing

Every mass tort matter that reaches settlement creates at least one, and usually several, re-papering or re-enrollment moments. Fee restructuring. New co-counsel. Settlement opt-ins. Trust distributions. Bankruptcy plan votes. Each one is a completion campaign hiding inside a legal formality.

The firms that treat these moments as what they are (outreach problems with measurable yield curves and specific infrastructure requirements) hit their numbers. The firms that treat them as "send a letter and hope" leave money on the table every single time.

If you are running inventory cases and you do not have a completion stack that can handle a 5,000-claimant re-papering campaign on two weeks' notice, the question is not whether you will need one. The question is whether you will have it when the deadline lands.
