TL;DR: Claims usually get held up by missing documents, not missing signatures. That is why a supporting document upload for claims and verification workflows can make such a difference. The form comes back signed quickly, but the estimate, photo, or report that is supposed to go with it arrives late, or not at all, because it travels through a separate channel. The fix is simple: ask for the document at the same time and in the same place as the signature. This guide shows you how.
If you handle claims, you already know the pattern. The signature isn’t the slow part. It’s the evidence around it, an estimate stuck in someone’s inbox, a photo too blurry to use, a document nobody’s sure was ever asked for.
The usual fix is to add another channel: a portal for uploads, an email thread for whatever the portal misses, a reminder system to chase what’s still missing. Each one helps a little and adds a little more to track, until you’ve got a signature status, an upload status, and a follow-up status, all for one claim.
Here’s the better fix. Ask for the document in the same step as the signature, so there’s one thing to check instead of three. This guide walks through where that actually applies in a claim, and shows exactly how to build it.
Key takeaways
- Claims stall because the evidence and the signature arrive through different channels. Putting both in one step is the fix.
- An attachment field is the tool for this: it adds an upload box right next to the signature, so both come back together.
- It checks the basics, like file type and whether something was uploaded. It doesn’t check if the document is genuine, so keep a person in charge of that.
- When something’s missing, resend the same request instead of writing a new email from scratch. It’s faster and the claimant knows exactly what’s left.
- A well-built eSignature platform brings all of this together: the upload field, ID checks for the signer, and a record of who sent what and when.
The claim starts fine. The evidence request is where it slows down
A claim usually starts with the claimant. They report the loss, give the policy number, the date, the amount, and what happened. That part is quick and doesn’t need much from you.
The slowdown starts with the next step: asking for proof. This is where the fix begins. Instead of sending a signature request and a separate document request, send one request that asks for both. Many insurers already sign the claim form itself using a saved template, so the same fields show up every time. That signed form becomes the anchor the rest of the evidence gets attached to.
Vague requests get vague documents back
Once a claim is open, someone has to decide what proves it. A repair estimate. A police report. A discharge summary. What’s needed depends on the claim, which is exactly why a generic request gets a generic file back.
The fix here costs nothing extra: name the document instead of the action. “Upload document” tells a claimant nothing. “Upload the contractor’s repair estimate, dated in the last 30 days” tells them exactly what to send. That one change is often the difference between getting it right the first time and asking again.
One request, one place, instead of three
This is the core fix. Instead of a portal login, a separate app, an email attachment, and a manual entry into your claims system, all tracked separately, the claimant provides the document as part of the same session where they sign.
That’s exactly what an attachment field does. It’s a small upload box the sender adds to the document, right next to the signature. The claimant fills it in, uploads the file, and signs, all in one sitting. Nothing to log into separately, nothing to email afterward. One status, one file, one place to check.
What the upload step checks, and what it doesn’t
A good upload field checks two simple things: is the file the right type, and did the claimant actually upload something when it was required. That much happens automatically, before they can finish signing.
What it doesn’t do is check whether the file is real. It won’t scan for viruses, catch a duplicate, or confirm a document wasn’t altered. Those checks belong to your claims system, once the file lands there. Knowing this upfront means you won’t rely on the upload step for something it was never meant to do, and you’ll keep a person reviewing what actually matters.
Knowing when something arrived helps more than you’d think
By the time someone reviews the claim, the question isn’t whether a file showed up. It’s whether it’s genuine, complete, and matches what the claimant reported.
Here’s what helps with that: a simple record of exactly when each document was uploaded and how the person was checked. It won’t prove the document is real, but it tells a reviewer exactly when and how it arrived, which matters if a claim ever gets questioned later.
For claims where you need to be more sure who’s actually signing, not just what they uploaded, add an ID check. A photo of a license confirms a file was submitted. It doesn’t confirm who submitted it. Checking the signer’s identity separately, with a government ID and a quick selfie match, closes that gap for claims where it’s worth the extra step.
When something’s missing, don’t start over
Most claims don’t clear review the first time. Something’s missing or unclear, and someone has to ask again.
A fresh, unstructured email is how a claim quietly loses another week. The better fix: resend the exact same request you used the first time, but ask for just the one missing item. The claimant sees precisely what’s still needed instead of guessing, and it lands in the same file as everything they already sent.
Keep the paperwork and the proof in one place
Once a claim is approved, rejected, or paid, that decision happens outside the document request entirely. It’s made by a person or a system built for that.
What sticks around is the record. If a claim ever gets questioned later, what you’ll want to pull up is the signed form, the attached evidence, and a simple timeline of when it all came in, not someone’s memory of the file. Keeping all of that together from the start saves you from digging through old emails and folders when it matters.
Putting it into practice with BoldSign
Everything above works with any eSignature platform built to support it. BoldSign is built around this exact pattern, so here’s how each piece maps to a real setting.
The document request runs through an Attachment field. The sender gives it a title, an instruction if needed, a list of accepted file types, and marks it required if the claimant can’t finish without it. A single document can have more than one attachment field, each assigned to a different signer, which is useful when more than one person needs to provide something, like a claimant and a contractor submitting their own estimate. The setup is covered in the guide to requesting attachments from signers and the walkthrough on collecting supporting documents during signing. One thing to know: password-protected files don’t work, so a locked statement has to be unlocked before it’s uploaded.
Choose a signer authentication method based on the risk level of the claim. For claims requiring stronger identity checks, use ID verification, which checks a government-issued ID and selfie, or Knowledge-Based Authentication (KBA), which verifies the claimant through security questions. For lower-risk claims, an access code or one-time code sent by text message may be sufficient. Learn more about the available signer authentication methods.
The simple timeline that helps a reviewer comes from the audit trail, which records who did what and when, downloadable once everyone’s signed. Saving the whole setup as a template is what makes resending an easy fix rather than a rebuild. Teams building this into their own claims system instead of the BoldSign app can do the same thing through the attachment field API, and the insurance workflows page covers more ways this pattern gets used.
To set it up:
- Log in to BoldSign and upload the claim document, or select a saved template created for that claim type.
- Add the claimant and any other required recipients. Open the recipient settings and select ID verification or Knowledge-Based Authentication (KBA) if the claim requires stronger identity authentication.
- On the fields page, assign each attachment field to the right signer, name it for the specific document, and set the file types and whether it’s required.
- Add the signature field and send.
- Once it’s signed, download the attachments, the signed document, and the audit trail, and pass the file to your claims system for the checks and review that happen there.
- If something’s missing, resend the same template with one attachment field for just that item.
Wrapping up
The fix is simple: stop treating the evidence as a separate errand from the signature, and ask for both in the same place. That one change is what actually speeds up a claim.
Everything after that, the deeper checks, the review, the decision, still depends on your claims system and the people running it. BoldSign handles the request and the upload cleanly. The rest is still on your team, same as always.

FAQs
What file types can a claimant upload?
BoldSign’s attachment field accepts PDF, Word (.docx), and image files (.jpg, .jpeg, .png). When setting up the supporting document upload, you can specify which of these formats the claimant is allowed to submit. Clearly mention the accepted formats in the field instructions, especially when requesting items such as scanned forms, IDs, or photos.
Does the claimant need a BoldSign account to sign or upload anything?
No. They get an email with a link, click through, and complete everything, the signature and any uploads, right from there. No account, no login, no extra step for them.
Can I ask for more than one document in the same request?
Yes. A single BoldSign document can contain multiple attachment fields, making it easy to manage supporting document uploads in one request. For example, you can request an estimate, an ID, and supporting photos separately, with a clear label and accepted file format for each attachment field.
What happens if a claimant doesn’t upload a document marked as required?
They can’t finish signing. A required attachment field holds up the whole document until something is uploaded, so you’re never left with a signed form and a missing file, the way you would be with a separate email request.
If a claim has more than one signer, can they see each other’s uploads?
No. When a document goes to more than one signer in order, an earlier signer can’t see what a later signer uploads, and a later signer can’t see an earlier one’s attachment either. Each person only sees what they’re asked to provide.
Does this same setup work for claims outside insurance, like warranty or reimbursement claims?
Yes. The pattern doesn’t depend on the claim type. Any process where someone has to submit a form and proof together, a warranty claim, an expense reimbursement, a benefits request, works the same way: one attachment field per document, tied to the signature.
