Engagement letters, retainer agreements, authorizations, and settlement documents all need signatures, and every day a document sits unsigned is a day the matter does not move. Electronic signatures fixed the printing and scanning problem years ago. The 2026 question is where the signature happens and where the signed document ends up.
Clio's 2025 Legal Trends Report found electronic signature tools are among the most popular technologies for mid-sized firms, used by 45%. The decision now is less whether to use e-signature and more how it connects to the rest of your workflow.

The 7 best e-signature tools for law firms in 2026
1. Relaw - best e-signature connected to intake, drafting, and the portal
Best for: Firms that want the whole path from questionnaire to generated document to signed PDF on one record.
Relaw includes first-party e-signature, so you do not pay for or manage a separate signing product.
What Relaw includes:
- Signing from generated documents - documents produced from intake answers and your own templates go straight to signing
- Secure signing links - clients sign from any device without a separate account
- Client portal signing - documents appear in the portal for signature
- Multiple signers - with signing status tracked
- Audit trail and certificate of completion - a record of the signing events
- Signed PDFs on the file - the completed document is retained with the client's documents
- Reminders - follow-ups for unsigned documents
Pricing: Included in Relaw. Standard from $269 per month on annual billing and Pro from $349 per month on annual billing. 14-day trial after onboarding.
Honest limits: Some documents, such as wills, have execution requirements (witnesses, notarization) that e-signature alone may not satisfy in your state. Relaw supports the firm's process; the attorney decides how each document must be executed. Firms with enterprise identity-proofing requirements may need a specialist tool.
Why it ranks first here: A standalone signing tool starts at the moment a PDF exists. Relaw starts earlier, with the intake that creates the document, and ends later, with the signed copy filed on the matter and the next task triggered.
2. DocuSign - most recognized standalone option
Best for: Firms whose clients or counterparties expect DocuSign and need deep integrations.
Reported 2026 pricing: Personal around $15 per month with a low envelope cap, Standard around $25 to $45 per user per month depending on term, and newer agreement-management plans with seat minimums. Envelope limits and add-ons can raise the real cost.
Strengths: Brand recognition, integrations, enterprise controls. Limits: Cost and envelope caps for busy firms; separate from your matter record.
3. Dropbox Sign - best standalone value

4. Adobe Acrobat Sign - best for Adobe-standardized firms
Best for: Firms already paying for Acrobat.
Reported team pricing runs roughly $15 to $24 per user per month.
5. PandaDoc - best for proposals plus signing

What it really costs
Standalone e-signature adds up. DocuSign's newer plans carry seat minimums that reviewers say set a practical floor of $225 per month, lower tiers cap envelopes, and Dropbox Sign, Adobe Sign, and PandaDoc are each a per-user subscription on top of your practice management platform. You also pay in time moving signed PDFs back onto the matter.
In Relaw, e-signature is included in the platform, so there is no separate signing subscription and signed documents land on the client file automatically. When you compare, count the signing tool, the seats, and the filing time.
How to choose
- If you want the signed document to land on the file automatically, use the platform's built-in signing, such as Relaw
- If clients or partners demand DocuSign, keep it for those cases
- If you only need signatures and want the lowest cost, compare Dropbox Sign and bundled options
Ask each vendor: Is there an envelope limit? Where does the signed PDF go? Can signers sign without an account?
