Divers hate releases. But to dive, we usually have to
sign a form releasing the operator from liability in the
case of a wrongful death, and the courts usually declare
them valid. However, because a waiver allows a scuba
operator to avoid liability for negligence, courts typically
interpret them against the operator.
Determining Validity  
Despite having signed a release and agreeing not to
  sue, divers who are injured (or their heirs) occasionally
  believe they have grounds for a lawsuit. Whether they win
  depends on several factors. The most significant may be
  where the claim is filed. State laws, although similar, are
  construed differently, and judicial sympathy for clauses
  that release the blame — exculpatory clauses — varies
  widely. For example, the Wisconsin Supreme Court has
  considered such agreements six times in 25 years and
  has invalidated them all, while releases in Florida are
  routinely upheld even if they shield operators from gross
  negligence. That’s not good for Florida divers.  
Another consideration is whether a federal statute prohibits
  boat owners from escaping liability. Unfortunately,
  diving accidents rarely trigger this provision — it requires
  that the injury occur in navigable waters and the incident
  must have a potentially disruptive impact on, and substantial
  relationship to, traditional maritime activity.  
If this Federal statute does not void the waiver, courts
  look to the following principles:  
Informed Consent: You must have signed your release
  voluntarily to forego the right to sue. The language must
  be conspicuous and so clear a layperson can understand
  it. Many are voided because they failed this requirement.  
Public Policy: Although a waiver will not be enforced
  if it violates some public policy, this exception — which
  assesses whether the service is essential and the parties in
  an unequal bargaining power — is almost never raised for
  successful cases involving recreational releases.  
Take it or Leave it: An adhesion contract is a “take
  it or leave it” proposition. When one party is in a superior
  bargaining position, and the service is unavailable
  elsewhere, such a contract may be invalid. However,
  somewhat disingenuously, judges usually assert that divers
  could (1) object to signing and participate anyway, (2)
  convince a shop or boat owner to change the document,
  or (3) choose another provider. Any diver knows that the
  first two are virtually impossible and the third is futile, as
  all operators require waivers.  
Dangers in Diving:  
Diving is viewed as inherently dangerous, and courts
  accept the argument that the plaintiff knew the dangers.
  So, these clauses typically are upheld. What judges are
  really saying is that they think anyone crazy enough to
  strap a tank on his back and go diving underwater is
  responsible for whatever happens to him. Nevertheless,
  creative lawyering has helped some divers. For example,
  a plaintiff was allowed to sue Little Cayman’s Southern
  Cross Club after he was injured by a huge wave on the way
  to the dive site (Reuther v. Southern Cross Club). The attorney argued successfully that, although the risks associated
with diving were explained and assumed, the release did
not mention the boat ride. Therefore, the waiver did not
apply and the defendant was liable.
Diving Abroad  
When an accident occurs in a foreign country, if possible
  it is usually better to sue in the U.S., even with the
  waiver as a defense. For one thing, in some countries the
  diving is much better than the judicial system. Further,
  State laws differ and statutes in the states involved might
  protect you more. In addition, not only is it more convenient
  and less expensive to litigate at home, but also most
  judges tend to favor their own residents.  
The primary obstacle to suing in an American court
  is the probability that it lacks personal jurisdiction over
  a nonresident defendant. For example, in Delgado v. Reef
  Resort Ltd. the diver drowned in Belize. His widow, who
  lived in Florida, sued in Mississippi, alleging that Reef
  Resort, a Belize corporation did business in that state.
  The defendant remanded the case to Federal court and
  sought to have the case dismissed.  
Because the plaintiff failed to establish that the court
  had jurisdiction over the resort, the judge refused to
  let the case continue. Although “doing business” in
  Mississippi generally is sufficient under the long-arm statute
  to subject a nonresident defendant to suit, this law
  could not be used by nonresidents like the plaintiff.  
How to protect yourself? If you dive in a foreign country,
  try to arrange the trip through an American provider.
  That way, if you sign his release before leaving your state,
  and problems arise, you can most likely sue at home. In
  “admiralty jurisdiction,” the federal statute may invalidate
  the release and give an American court jurisdiction over
  the incident. There may also be relief under the Death on
  High Seas Act.  
The Rights of the Heirs  
Eugene Pietroluongo contacted Regency Diving
  Center (RDC) for advanced training. He signed an agreement
  exempting everyone connected with the course
  “from all liability or responsibility whatsoever for personal
  injury . . . or wrongful death . . . on behalf of myself and
  my heirs.” Notably, Pietroluongo was a lawyer who certainly
  understood what he was signing.  
Then Pietroluongo disappeared during a dive. His
  body was discovered in 66 feet of water with “an ample
  supply of air in his tank and equipment in working
  order.” The medical examiner ruled it an “accidental
  drowning.” His estate sued.  
In Gershon v. Regency Diving Center — a decision the
  defense attorney warned “could eliminate scuba diving in
  New Jersey” — the court held a release did not prevent
  decedent’s heirs from bringing a wrongful death action.
  The ruling allows for imposing substantial liability on providers
  and greatly diminishes the value of waivers.  
This court said the waiver could not preclude such a
  suit because the class of heirs entitled to bring such an
  action is not defined until someone dies. Second, as the
  beneficiaries had not signed the agreement, they should
  not be bound. Third, the Wrongful Death Act is remedial
  in nature and, therefore, must be construed to achieve its
  “purpose of creating a right of recovery for the economic
  loss caused by the death of a family member.”  
Waiver’s Effective Date 
Almost three weeks after she signed a waiver for herself
  and her heirs, Linda Marie Wieditz went diving with
  the Culebra Dive Shop in Puerto Rico. Problems with
  the boat and one passenger caused the crew members to
  select another destination and required one of the two
  instructors to stay near shore. Immediately after the five
  divers entered the water, the instructor realized the current
  was too strong. He ordered everyone to reboard.
  Wieditz was last seen trying to swim to the vessel. The
  instructor lifted anchor to tow others who were drifting.
  Wieditz disappeared; her body was never recovered. In
  Sylva v. Culebra Dive Shop, the question was whether a
  release, signed 20 days before the fatal dive, remained in
  effect.  
When Wieditz’s husband, who had not been on the
  trip, sued for wrongful death, defendants asserted that
  the release barred his claim. But he alleged that, because
  it was not clear whether the release was in effect at the
  time of the accident, that he was allowed his day in court.  
A review of the release’s language found that it did not
  specifically state if it was applicable only for the day it was
  signed. Further, it failed to say whether it covered one or
  multiple dives. Concluding that some questions — including
  a request for any medications taken during “the past
  24 hours”— suggested the waiver was only for a day, the
  court stated the answer depended on the parties’ intentions.
  As this is a question of fact for the jury, plaintiff
  could go to trial and has.  
The conclusion is puzzling as the court should simply
  have invalidated the waiver because of the ambiguity.
  Remember, the rule is that releases are not favored and,
  thus, are construed against the drafter. The odds are
  against the injured or families of the deceased divers
  when they go to court after signing a release.
