Real estate leads every other regulated industry on e-signature adoption. 79% of Realtors now use e-signature tools, the single most-used technology in the profession, according to the National Association of Realtors’ 2025 Technology Survey. Legal and financial services are close behind, while healthcare and other heavily regulated sectors trail by years, not because the technology is missing, but because the compliance rules are only now catching up.
How many Realtors and real estate agents use e-signatures?
Real estate is the clearest adoption leader with a named, dated survey behind it. NAR’s 2025 Technology Survey found that 79% of REALTOR members use e-signature tools, ranking it above social media (75%), drone photography or video (52%), and AI-generated content (46%) as the single most widely used technology in the profession. The survey was published as a press release on September 18, 2025.
The ranking is not close. E-signature has outpaced every marketing and prospecting tool real estate agents have adopted, largely because it sits at the center of the transaction itself: listing agreements, disclosures, and purchase contracts all move faster once a buyer or seller can sign from a phone instead of waiting for a fax or an in-person meeting.

Faster signing also means faster closings, and that time savings shows up across contracts generally, not just in real estate. See our contract management time and cost data for 2026 for how manual, paper-based signing slows down deals across every industry, not only property transactions.
E-signature is now table stakes in real estate. An agent without it is asking clients to accept a slower, more error-prone process than 79% of the competition already offers.
How fast is e-signature adoption growing among law firms?
Law firms have moved from cautious adopters to heavy users in a few years. Clio’s 2025 Legal Trends Report for solo and small firms found that 72% of solo law firms and 78% of small law firms now use e-signature tools, and adoption among solo and small-firm practitioners is up more than 40% over the past three years, making it the fastest-growing legal technology category the report tracks.
The driver is client-facing, not just internal efficiency. Firms that added e-signature saw measurable gains in engagement letter completion, and Clio’s data links e-signature adoption to improved client intake conversion alongside online payments and text messaging. A signature that used to require a scanned PDF and an email chain now closes in minutes, which matters most at the point where a prospective client decides whether to actually retain the firm.
This mirrors what we found reviewing enforceability of another one-click legal moment: the click itself matters less than what a business can prove about consent and disclosure afterward. See our clickwrap enforceability data for 2026 for how that plays out when a signed or clicked agreement ends up in court.
Legal adoption is not universal yet, but the direction is set. A firm still requiring wet-ink signatures in 2026 is asking clients to work around a workflow that most of its competitors have already replaced.
How are financial regulators changing the rules on e-signatures?
Financial services adoption has been paced by regulators, not held back by them. In 2019, the SEC approved a FINRA rule change permitting electronic signatures for discretionary brokerage accounts, formally extending e-signature acceptance into a part of account paperwork that had previously required a wet-ink signature. FINRA’s underlying customer-account rule, Rule 4512, still points firms back to the federal ESIGN Act and SEC guidance to determine what counts as a valid electronic signature.
The most recent change lands right at the start of this post’s publication year. An amendment to FINRA Rule 17a-5 permits electronic signatures on annual audit reports and FOCUS reports for filings made on or after January 1, 2026, closing one of the last major gaps where broker-dealers were still required to produce a physical signature on a recurring regulatory filing.
Each rule change has followed the same pattern: a specific document type, once carved out as an exception, gets folded into the same electronic-signature framework everyone else already uses. That steady, document-by-document expansion is why financial services adoption looks less dramatic than real estate’s headline number, even though the underlying shift is just as real.
Why does healthcare lag behind on e-signatures?
Healthcare’s adoption story splits in two, and the split explains the lag. On the prescribing side, electronic signatures for controlled substances are nearly universal: Surescripts’ 2025 Annual Impact Report found that 98.3% of US pharmacies and 84.4% of e-prescribers nationwide are enabled for electronic prescribing of controlled substances (EPCS), a system that processed 323.2 million controlled-substance e-prescriptions in 2025 alone.

Outside of prescribing, general clinical consent forms and administrative sign-offs move much slower, and the regulatory timeline shows why. CMS finalized the first HIPAA-adopted federal standard for electronic signatures on health care claims attachments only in 2026, and the rule does not take effect until May 26, 2026, with full compliance not required until May 26, 2028. That is years behind where financial services and real estate already sit, and it means a hospital or clinic can be fully compliant today while still routing most non-prescribing paperwork through paper or unstandardized digital workarounds.
Healthcare is not behind because clinicians distrust electronic signatures. It is behind because the specific federal standard covering most of its paperwork has a compliance clock that only started running in 2026.
Which industries are furthest ahead, and which are catching up?
Putting the data side by side shows two different kinds of leaders: industries where adoption is driven by client and market expectations, and industries where adoption is driven by a regulator finally clearing the path.
Figure 3: Real estate and legal adoption is largely market-driven; financial services and general healthcare records are still working through staged regulatory permission. Source: synthesized from the survey and regulatory data cited above.
| Industry | Adoption signal | Primary driver | Data year |
|---|---|---|---|
| Real estate | 79% of Realtors use e-signature software | Client and market expectation | 2025 |
| Legal (solo/small firms) | 72% to 78% of firms use e-signature tools | Client intake and conversion | 2025 |
| Financial services | Staged FINRA rule changes now cover discretionary accounts and audit filings | Regulatory modernization | 2019 to 2026 |
| Healthcare (prescribing) | 98.3% of pharmacies and 84.4% of e-prescribers are EPCS-enabled | DEA controlled-substance rules | 2025 |
Every industry in this table is moving toward full adoption. The gap between the leaders and the laggards is mostly a gap in how long each sector’s own regulator has allowed a fully electronic process, not a gap in whether businesses or consumers want one.
What laws make e-signatures legally binding in the United States?
The legal foundation predates most of the adoption numbers above by two decades. The federal Electronic Signatures in Global and National Commerce Act (ESIGN Act), signed into law in 2000, makes electronic signatures and records legally enforceable in interstate and foreign commerce, provided the signer consents to sign electronically. At the state level, the Uniform Electronic Transactions Act (UETA), drafted by the Uniform Law Commission in 1999, has been enacted in 49 states plus Washington DC, Puerto Rico, and the Virgin Islands. New York is the only state that has not adopted UETA; it instead relies on its own Electronic Signatures and Records Act (ESRA), enacted the same year as the ESIGN Act, according to a New York City Bar Association analysis of the two laws.

Legal validity has never been the real bottleneck for most industries. What actually determines whether a signed document holds up is whether the signer’s intent and consent were captured, not the medium of the pen.

The same test applies whether someone is clicking to sign a lease or clicking to accept a website’s terms. If you run a business that pairs e-signature workflows with a click-to-agree flow, the underlying terms and conditions still need to state plainly what the signer is agreeing to, since a court applying the test above will look at what was disclosed just as closely as how the signature itself was captured.
The Bottom Line
Real estate’s 79% e-signature adoption rate is not an outlier so much as a preview of where every regulated industry is headed. Legal is close behind on its own named survey data, financial services has been opening up document type by document type since 2019, and even healthcare, the clear laggard on general paperwork, has already reached near-total adoption on the one process, controlled-substance prescribing, where a federal mandate forced the issue years ago. The pattern across every industry in this article is the same: once a regulator or a market of clients settles the question, adoption follows quickly, and it does not go back.
Frequently Asked Questions
Which industries have the highest e-signature adoption? Real estate and legal lead by named survey data. 79% of Realtors use e-signature tools, the single most-used technology in the profession (NAR, 2025), and 72% to 78% of solo and small law firms use e-signature tools (Clio, 2025).
How many people or businesses use DocuSign? DocuSign reported nearly 1.7 million customers and more than 1 billion users worldwide as of January 31, 2025, according to its fiscal year 2025 Form 10-K filed with the SEC.
Are e-signatures legally binding in the United States? Yes. The federal ESIGN Act (2000) and the Uniform Electronic Transactions Act, adopted by 49 states plus DC, give electronic signatures the same legal standing as handwritten ones when both parties consent to sign electronically. New York uses its own equivalent law, ESRA.
Why is healthcare behind other industries on e-signature adoption? Mostly regulatory timing, not technology limits. CMS’s first HIPAA-adopted electronic signature standard for claims attachments does not take effect until May 26, 2026, and full compliance is not required until May 26, 2028, years after similar rule changes landed in financial services.
