Wet Signature and Seal vs Digital Signature: What Contractors Need to Know

digital bond execution contractors

A contractor called me last spring, convinced he’d done everything right on a public bid. His bond was ready, and his paperwork was clean. The problem was that he’d submitted a digital bond to an obligee that still required a wet signature and a raised corporate seal. The bond was rejected, and he missed the deadline by two hours.

That’s a preventable problem. Knowing which format each obligee accepts before you submit is one of the simplest things a contractor can get right.

How digital bonding works

After COVID-19, courts, public owners, and sureties moved quickly to digital execution. Many jurisdictions eliminated the requirement for physical documents. Surety companies adopted secure signature platforms that capture signer identity, timestamps, and document history. These records are tamper-evident and comply with state electronic transaction laws.

Digital bonds reach the obligee faster. If a bond is returned due to wording issues or incorrect obligee information, your agent will fix and reissue it immediately. With a wet-seal bond, you reprint, re-sign, reseal, and reship. On a tight deadline, that process can cost you the bid.

Digital execution also eliminates the physical problems associated with ink bonds: smudged signatures, flattened seals, and illegible handwriting. Owners receive a clean, authenticated document they can verify without handling paper.

When wet signatures and raised seals are still required

Despite how far digital acceptance has spread, several states still require wet signatures and corporate seals on certain bond types. These requirements stem from statutory language or agency-specific rules that haven’t been updated.

Under the current public procurement rules, these states require handwritten signatures and raised seals for various construction bonds:

  • California
  • Florida
  • New York
  • Pennsylvania
  • Alabama
  • Delaware

Even in states that generally accept digital bonds, individual cities, counties, and school districts sometimes maintain their own ink requirements. Always confirm with the obligee before you submit, not after.

“A contractor who assumes digital acceptance in the wrong jurisdiction learns at the worst possible moment. Confirm first. The cost of asking is nothing. The cost of getting it wrong can be a missed bid.”

How to know which format applies

Use digital execution when:

  • The obligee has confirmed they accept electronic bonds
  • You’re working against a tight deadline and need the ability to correct quickly.
  • You’re managing projects across multiple provinces with varying requirements

Use wet signatures when:

  • The obligee requires ink and a raised seal
  • Your project falls under a statute that predates electronic acceptance.
  • The bond form or jurisdiction hasn’t been confirmed as digital-friendly.

Your bonding agent should be able to confirm the requirement for any state or obligee you work with. If they can’t, that’s worth noting.

What good preparation looks like

Contractors who regularly bid in multiple states keep a record of the format requirements for each obligee they work with. That information is easy to maintain and saves real time on every subsequent bid in that jurisdiction.

The contractors who run into problems are the ones who assume. They’ve used digital before on a similar project and figure the same rules apply. Sometimes they do. Sometimes they don’t, and finding out at submission is the worst time to learn that.

Check early. Confirm directly with the obligee or through your agent. If the deadline is tomorrow, confirmation needs to happen today.
