Industries where wet ink is still required

E-signature laws cover most contracts, but specific document types still require wet-ink signatures in most jurisdictions. Knowing the list saves you from invalid contracts.

The universal exceptions (nearly all jurisdictions)

### Wills and testamentary documents Requires wet ink + witnesses in most jurisdictions. A few states/countries have introduced "electronic wills" laws (Nevada, Florida, parts of Australia) but adoption is limited. If you're drafting a will, use wet ink.

### Codicils (amendments to wills) Same as wills — wet ink + witnesses.

### Certain real estate documents

• Deeds: varies widely. US states vary; many still require wet ink + notary. AU allows e-signing of contracts of sale but physical title registration sometimes requires wet signatures.
• Mortgages: varies. US Remote Online Notarization (RON) laws changed this, but some states still require wet ink.
• Title transfers: often require wet ink at the government registry office.

### Adoption documents Wet ink in most jurisdictions.

### Divorce decrees Entered by court; court's signature is the one that matters, not typically electronic.

### Marriage certificates Issued by government office; wet ink + official seal.

### Powers of attorney Varies significantly. Many jurisdictions require wet ink + witness + sometimes notary. Some allow e-signing with additional safeguards.

Industry-specific requirements

### Legal services Court filings vary by court. Federal courts widely accept e-filing. State courts vary. Always check the specific court's rules before e-filing.

### Notarization If a document requires notarization, most jurisdictions require the notary to witness the signing in person or via Remote Online Notarization (RON) — not just via an e-signature platform.

### Financial services Some account opening documents (particularly for investment accounts at major brokerages) still require wet ink for compliance with pre-existing paper processes. Check with the specific institution.

### Real estate closings Varies by state. US has been moving toward e-closings since 2020 but adoption is inconsistent. The title insurance company and lender dictate acceptance.

### Immigration documents US Citizenship and Immigration Services (USCIS) accepts some forms electronically but many still require wet ink. Check the specific form's instructions.

### Healthcare advance directives Varies by jurisdiction. Some states accept e-signed living wills with additional safeguards; others require wet ink + witnesses.

The pattern

When wet ink is required, it's usually because: 1. The document has witnesses requirements that are easier to meet in person 2. The document is recorded at a government registry that requires wet signatures 3. Traditional legal conservatism (wills) 4. The document's legal effect is so severe that strong evidence is desired

When in doubt

If you're unsure whether a specific document type can be e-signed: 1. Check the governing statute for your jurisdiction 2. Check any regulatory body's guidance for that industry 3. Ask the opposing party (they may require wet ink even when law permits electronic) 4. Ask your lawyer

Hybrid workflows

For documents that require some wet-ink elements, a hybrid approach works: 1. Prep the document on SnapPDF 2. E-sign any permissible portions on SignBolt 3. Print the signed document 4. Wet-sign + witness/notarize the required elements 5. Scan back and retain both electronic + paper originals
