Liability waiver

A liability waiver is a document in which a participant accepts the known risks of an activity and agrees, within limits set by law, not to hold the organiser responsible for certain injuries.

What it is

Gyms, climbing walls, tour operators, event hosts, studios and schools ask people to sign a waiver before they take part. It is also called a release of liability or an assumption of risk form. The goal is to show that the person was told about the risks and chose to go ahead.

A waiver is not a shield against everything. Courts in many places refuse to enforce waivers that try to excuse gross negligence or deliberate harm, and some states limit waivers more than others. Wording, layout and the way it was presented can all matter. So the document deserves a lawyer's review in the state where you operate.

When it is used

Sports, fitness and outdoor activities.
Equipment rentals, such as bikes, boats or tools.
Events, races and volunteer days.
Clinics and wellness businesses that offer classes or treatments with some physical risk. A waiver is not a consent to medical treatment, which is a different document.
Education trips and after-school programmes.

What it usually contains

Section	What it covers
Activity description	What the person will do, where and when
Known risks	A plain list of the risks, so the person can't say they weren't told
Assumption of risk	The participant's statement that they understand and accept those risks
Release	The claims the participant gives up, within what local law allows
Participant duties	Following rules, using equipment properly, telling staff about conditions
Medical authorisation	Permission to call for emergency care, if the activity needs it
Minors	A parent or guardian section, often with its own wording
Severability and governing law	What happens if part is unenforceable, and which state's law applies
Signature, name and date	The participant, and a guardian for minors

Things to get right

Make the risk section readable. Small grey text buried at the end works against you. Put the key terms where the signer will see them before signing.
Get it signed before the activity. A waiver signed after an injury is a different matter.
One person, one waiver. A family of four should give four records, or one per adult with minors listed and a guardian signing.
Keep it for as long as a claim could arise. Your lawyer can tell you the period. Store the sealed PDF where your team can find it by name and date.

Please read this as general information, not legal advice. Waiver law depends on the state and the activity, and a local lawyer should approve your form.

How to send it for signature with docuinked

In the app

Upload the waiver PDF, add a checkbox next to the risk section, then signature, name and date fields. Save it as a template. At check-in, enter the participant's name and email and send. They sign on their phone at the desk. The signing page shows the whole document before the signature, and every view and click goes into the audit trail.

By API

A booking system can send the waiver as soon as someone books. This example adds a required checkbox next to the risk text.

curl https://docuinked.com/v1/documents \
  -H "Authorization: Bearer $DOCUINKED_API_KEY" \
  -H "Idempotency-Key: waiver-booking-88213" \
  -H "Content-Type: application/json" \
  -d '{"title": "Waiver, Saturday climbing session",
       "pdf_url": "https://example.com/waiver.pdf",
       "signers": [{"name": "Sam Ortiz", "email": "sam@example.com"}],
       "fields": [{"signer": 1, "kind": "checkbox", "anchor": "I have read the risks above", "required": true},
                  {"signer": 1, "kind": "signature", "anchor": "Participant signature:"},
                  {"signer": 1, "kind": "date", "anchor": "Date:"}],
       "send": true}'

Then listen for document.completed with a webhook and mark the booking as cleared. The Idempotency-Key means a retried booking event will not send a second waiver.

From an agent

An assistant that handles bookings over MCP can prepare the waiver with create_from_template. A live send returns an approval_url, and a named person on your team approves it. For waivers going to every customer, many teams send from their own server instead, with a "Sends directly" key, because the document never changes. See approvals.

Daily volume during the beta

Live sends are capped at 100 a day per account during the beta. A busy venue may outgrow that. Write to us before you rely on it, and see pricing. Sending many at once from a list is bulk send, which is coming and not available yet.

Common questions

Does an electronic waiver hold up as well as a paper one?

Being electronic is not by itself a reason to reject it under ESIGN and UETA. Whether a waiver holds up depends on its terms, the activity and state law, which apply the same way to paper.

Can a parent sign a waiver for a child electronically?

The signing works the same way. Whether a parent can waive a child's claims at all is a question of state law, and in some places they can't. Ask a lawyer.

Should I show the waiver on a tablet at the front desk?

You can, but a link to the participant's own phone gives a cleaner record. It ties the signature to their email and device, not a shared tablet.

What if a participant refuses to sign?

They can decline on the signing page, and you are told. What happens next is your policy. Many venues don't let people take part without a signed waiver.
