For mediators, solo plaintiff & defense lawyers, family + employment + PI
Defeat the “different draft” motion in 30 seconds. Cryptographically seal every mediated settlement at execution. From $6.99, no subscription.
The mediation is over. Both parties signed. Six weeks later opposing counsel files a motion to set aside, claiming the other side signed a different draft. Without a timestamped sealed copy, it is word against word. With ProofSnap: hand the court the ZIP plus a URL, the qualified timestamp date proves what was actually executed, and the motion collapses on its face.
At close of mediation, drop the signed PDF (wet-ink scan or DocuSign/Adobe Sign) into ProofSnap File Certifier. SHA-256 computed locally; the file never uploads. Receive a 10-file court-admissible ZIP: Bitcoin OpenTimestamps (US FRE 901 + 902(13)/(14) self-authenticating; admissible under FRE 408 for executed terms) + optional Disig eIDAS qualified timestamp (Reg 910/2014 Art. 41(2) legal presumption across all 27 EU member states). Single mediation $6.99, five $24.99 ($5/each), no subscription.
Also available for Microsoft Edge · SnapPack is a one-time purchase, credit card required, no subscription, no auto-renewal · credits valid 12 months.

10 seconds per settlement · File never leaves your device · Works wet-ink + e-signed
Sources: Clio Personal Injury Law Statistics 2026 (95% PI before trial), EEOC enforcement data (90% before trial). Qualified timestamps issued by Disig a.s. — QTSP on the EU Trusted List · ETSI EN 319 421/422 compliant. Self-authenticating under US FRE 902(13)/(14); admissible alongside FRE 408 for proving executed settlement terms.
Quick answer
How do you prove which draft of the settlement was actually executed?
Certify the executed settlement at the close of mediation. Drop the scanned wet-ink PDF (or DocuSign / Adobe Sign downloaded copy) into the ProofSnap File Certifier sidebar — SHA-256 is computed locally, the file never uploads. Within 10 seconds you receive a court-admissible 10-file forensic ZIP, anchored to the Bitcoin blockchain via OpenTimestamps (always on) and optionally sealed with a Disig eIDAS qualified timestamp — Regulation (EU) No 910/2014 Article 41(2) legal presumption of accuracy across all 27 EU member states. Self-authenticating under US FRE 902(13) and 902(14), so no expert witness is needed at a motion hearing. Admissible alongside FRE 408 for proving the executed agreement’s terms (not the negotiation). If the opposing party later files a motion to set aside claiming a different draft was signed, you hand the court the ZIP plus the Trust Verifier URL — their challenge collapses on the face of the qualified timestamp date. Single mediation $6.99, five mediations $24.99 ($5 each). No subscription.
Mediation-day kit · 4 steps from close of mediation to sealed ZIP
Seal the agreement before the second-thought call
Mediator best practice (per JAMS, IMI, ADR Center): “record for signature immediately to prevent second thoughts from destroying a good agreement.” ProofSnap adds the cryptographic seal in the same 60 seconds.
Before the mediation day — buy SnapPack
Install ProofSnap Chrome extension. Buy eIDAS SnapPack 1 ($6.99) for a single mediation or eIDAS SnapPack 5 ($24.99 = $5/mediation) for a quarter. Credit card required at checkout; no subscription, no auto-renewal, credits valid 12 months.
At close of mediation — sign + scan (or e-sign) immediately
Per JAMS / IMI best practice: do not let parties leave before the final settlement is signed. Wet-ink original signed by all parties + counsel → scan to PDF (any office scanner, 10 seconds). Or use DocuSign / Adobe Sign for fully electronic execution. The scanned or e-signed PDF is the operative document.
Drop into File Certifier — 10 seconds, file never uploads
Open the ProofSnap sidebar. Drag the executed PDF in. Toggle eIDAS Qualified Timestamp ON (recommended for any mediation involving an EU party, cross-border dispute, or contract over $100K). SHA-256 computed locally; only the 32-byte hash leaves the device. ZIP lands in downloads folder.
Email the ZIP to all parties’ counsel + your mediator file
Before the parties leave the conference room: email the evidence ZIP to opposing counsel, plaintiff counsel and your own file. Each party has the cryptographic seal in hand within minutes of execution. If a motion to set aside arrives six weeks later, the answer is the same ZIP — opposing counsel verifies it themselves at getproofsnap.com/verify/index.html in 30 seconds, no ProofSnap account.
No subscription · credits valid 12 months · SnapPack 1 ($6.99) also available for single mediation.
Who should seal every settlement — and what they stop fearing
Five settlement-side professionals, five distinct "different draft" scenarios that a 30-second cryptographic seal kills outright.
IMI Certified Mediators & private mediators
Stop fearing the post-mediation phone call. 651 IMI Certified Mediators worldwide; thousands of private mediators across JAMS, AAA, IMI rosters. The JAMS / IMI best practice already says "record for signature immediately to prevent second thoughts" — ProofSnap adds the cryptographic seal in the same 60 seconds. When a party calls Monday morning claiming the Friday-evening signature was on a different draft, the answer is the email you sent them Friday night with the ZIP attached.
With ProofSnap: $5 per mediation via eIDAS SnapPack 5. One sealed copy per case, archived in your mediator file alongside the wet-ink originals. No subscription; SnapPack credits valid 12 months.
Family law solo — divorce + custody MSAs
Stop defending the wording of the Mediated Settlement Agreement against buyer's remorse. Under Texas Family Code § 6.602, an MSA is binding + irrevocable if it states non-revocability (bold/underlined/CAPS) + signed by each party + signed by counsel-if-represented. Florida Rule 1.730(b) (amended April 2025) requires signature by each party or their full-authority representative under Rule 1.720(c) — counsel signature requirement deleted by Florida Supreme Court. In re Lee, 411 S.W.3d 445 (Tex. 2013): trial court may not refuse judgment on statutorily compliant MSA. Standard for setting aside is high (fraud, duress, mutual mistake) but the most common attack is "I signed a different draft" — defeated by a qualified timestamp on the executed PDF.
With ProofSnap: seal the executed MSA before the parties leave the conference room. When the motion to set aside arrives 30–90 days later, your client’s position is preserved without expert testimony.
Solo plaintiff PI & defense lawyers
Stop hand-typing settlement memos after the fact. ~95% of US personal injury lawsuits settle before trial (Clio Personal Injury Law Statistics 2026); average payout $52,900 across surveyed plaintiffs; federal court avg $75,000. Confidentiality clauses are standard. When the carrier’s back-office disputes the general release language, the structured settlement annuity terms, the Medicare set-aside (MSA) allocation, or the subrogation lien waiver six months later, the question is which version of the release was actually executed — ProofSnap’s timestamped ZIP is the irrefutable answer + ISO 27037 chain-of-custody record for the Form W-9 + 1099-MISC reporting trail.
With ProofSnap: seal each release at execution alongside the carrier’s payment terms. Solo PI lawyers running 20–50 settlements per year: SnapPack 10 ($49.99 = $5/case) covers an annual practice and pays for itself the first time a carrier disputes a subrogation lien waiver.
Employment lawyers — EEOC, ADEA, state FEPAs
Stop arguing about the release language at the OWBPA window. ~90% of EEOC cases resolved before trial. ADEA waivers for employees over 40 must satisfy 29 U.S.C. § 626(f) (Older Workers Benefit Protection Act): plain language + specific reference to ADEA rights + 21-day consideration + 7-day revocation + advised in writing to consult counsel. State FEPAs add layers: California DFEH (FEHA settlements), New York DHR, Texas TWC, Illinois IDHR each have their own release-validity rules. When the former employee revokes within the 7-day window and re-emerges months later claiming a different release was signed, the timestamped sealed copy proves the actual executed version — admissible under FRE 408 for proving the agreement’s terms.
With ProofSnap: seal each EEOC settlement, ADEA waiver and state-FEPA release at execution. Defeats the 7-day revocation gamesmanship + state-FEPA “ambiguous release” challenges without expert testimony.
Small-firm civil defense & commercial litigation
Stop being outspent on motion-to-enforce briefing. When opposing counsel files a motion to set aside on "different draft" or "mutual mistake" grounds, a small-firm defense lawyer typically spends 8–20 hours assembling file history, email threads and counsel declarations to prove which version was executed. Big-firm opposing counsel can outspend you on briefing. Common subject-matter use cases: antitrust private-action settlements (Sherman § 1, Clayton § 4 trebles), IP licensing settlements (Lanham Act trademark + Copyright Act royalty terms), UCC § 2-204 commercial-supply contract disputes, cross-border commercial settlements (EU/UK + US choice-of-law). A ProofSnap qualified-timestamp ZIP collapses the question on its face: court self-verifies in 30 seconds, motion denied without evidentiary hearing.
With ProofSnap: SnapPack 10 ($49.99 = $5/settlement) covers a small-firm annual practice. For firms with multiple settling attorneys or cross-border commercial volume: Company plan $18.99/seat/month (min 2 seats) gives unlimited file certifications + 5 eIDAS qualified timestamps per seat per month for EU-party settlements.
Adjacent ProofSnap use cases for legal professionals
If your practice also touches NDAs at deal close, freelance SOW disputes, vendor contract amendment audit trails, or court-admissible web capture of social media + news articles + counterfeit listings, four sibling Contract Vertical pages cover those workflows: NDA Version Proof → (founders, IP lawyers, M&A); Freelance Scope Creep Proof → (solo developers, designers, marketing consultants); Contract Amendment Audit Trail → (SMB Legal Ops, in-house counsel, SOX-driven CFOs); Page Vault Alternative → (court-admissible web capture, $4.99 vs $195/month). Same File Certifier (or page-capture) feature, same forensic ZIP, different per-use pricing.

Buy eIDAS SnapPack 5 — $24.99Two layers of proof. Three evidence rules.
Every ZIP anchored to Bitcoin on every plan. Add EU qualified timestamp for cross-border mediations where you want the burden of proof on the opposing party.
Layer 1 — Bitcoin OpenTimestamps
Included on every plan + SnapPack
SHA-256 hash anchored to Bitcoin via OpenTimestamps. Decentralised, tamper-evident. Once anchored, cannot be forged without breaking Bitcoin itself. Satisfies: US FRE 901 + FRE 902(13)/(14) self-authenticating (no expert witness needed at motion hearing). Admissible alongside FRE 408 for proving the executed agreement’s terms. Verifiable with open OpenTimestamps tools — no ProofSnap dependency for the long-tail.
Sufficient for: most US settlement enforcement, motion-to-set-aside defense, internal client file integrity.
Layer 2 — eIDAS qualified timestamp
From $6.99 single · $5 per mediation at 5+ volume
Disig a.s. (QTSP on the EU Trusted List) issues a qualified timestamp under RFC 3161 + ETSI EN 319 421. Adds eIDAS Art. 41(2) legal presumption of accuracy + integrity — burden of proof reverses, opposing party must rebut. Recognised in all 27 EU member states (Art. 41(3)) + UK retained eIDAS post-Brexit.
Required for: cross-border mediations (any EU party), high-value commercial settlements, anything you want presumed-accurate without expert testimony in EU courts.
US · FRE 408 + 902(13)/(14)
FRE 408 bars settlement negotiations as evidence of liability but allows the executed settlement to prove its own terms. FRE 902(13)/(14): cryptographic records self-authenticating without expert testimony — ZIP is your single-exhibit motion response.
State courts · MSA statutes
Texas Family Code § 6.602 + In re Lee, 411 S.W.3d 445 (Tex. 2013): MSA binding + irrevocable, trial court must enter judgment. Florida Rule 1.730(b) (April 2025 amend): signature by party or Rule 1.720(c) representative. Qualified timestamp evidences exact executed contents.
EU · eIDAS + 27 states
Reg 910/2014 Art. 41(2) legal presumption of accuracy; opposing party must rebut. Cross-border recognition Art. 41(3); UK retained eIDAS post-Brexit. Disig a.s. on the EU Trusted List, audited per ETSI EN 319 421/422.

Typical scenarios
Friday-evening mediation closed with wet-ink signatures by 18:45. I sealed the scanned PDF with ProofSnap and emailed the ZIP to both counsel before they left the parking garage. Monday morning, plaintiff’s spouse called my office in a panic, claiming a different draft was signed. I replied with a one-line email pointing back to Friday’s ZIP and the Trust Verifier URL. Total time on the issue: four minutes. The motion to set aside was never filed.
IMI Certified Mediator · family law — typical scenario
Opposing counsel filed a motion to set aside our Texas Family Code § 6.602 MSA 38 days after execution, claiming the financial-disclosure schedule had been altered. I attached the executed MSA ZIP to my response brief and noted the qualified-timestamp date. The court denied the motion at first hearing without an evidentiary phase. Saved my client approximately 12 billable hours that would have gone to assembling the file history. Cost: $5.
Family law solo · Dallas, TX — typical scenario
Six months after a $420K PI settlement closed, the carrier’s subrogation desk disputed the Medicare set-aside allocation in the executed release. At deposition I pulled up the ProofSnap Trust Verifier on my laptop, dropped the ZIP plus the executed release PDF, and the green “File matches certificate” appeared with the original timestamp date. The carrier paid the structured-settlement annuity on schedule the following week. Cost: $5 at settlement, saved at minimum 40 hours of file reconstruction.
Solo plaintiff PI lawyer · ~30 settlements/yr — typical scenario
These are typical use-case scenarios written by ProofSnap to illustrate fit, not customer testimonials.
vs DocuSign, Adobe Sign, Notary public, Wet-ink only
DocuSign and Adobe Sign prove who signed. A notary attests that someone signed. ProofSnap proves what was signed at exactly when. Complementary — not substitutes.
| Feature | ProofSnap | DocuSign / Adobe Sign | Notary public | Wet-ink only |
|---|---|---|---|---|
| Tamper-evident timestamp on the executed file | Signature audit log | Notarial cert (separate) | No | |
| eIDAS qualified timestamp included | Enterprise add-on | No (jurisdictional) | No | |
| Self-authenticating in court (FRE 902) | Requires witness | Yes (per FRE 902(8)) | Requires witness | |
| File never uploaded to third party | No (cloud-hosted) | Notary sees content | Yes (paper only) | |
| Time-to-seal at close of mediation | 10 seconds | Already signed in flow | Requires notary visit | As fast as parties sign |
| Per-mediation cost | $5–$6.99 | From $15/seat/mo subscription | ~$25 + travel | $0 (but no integrity proof) |
Comparison reflects publicly available 2026 pricing. DocuSign / Adobe Sign retain useful signature audit trails (who signed) but do not provide qualified-timestamp integrity on the file itself by default; ProofSnap sits alongside e-signature tools as the integrity layer. Notary remains useful for specific jurisdictional requirements (real-estate deeds, some immigration documents) but cannot scale to every mediation.
Frequently asked questions
Seal every settlement before the second-thought call.
~95% of US PI lawsuits + ~90% of EEOC cases settle before trial. The leverage moment is execution, not trial. A $5 per-mediation qualified timestamp is the cheapest insurance against the most common motion-to-set-aside theory.
