Trampoline Park, Backyard, and Product Scenarios in Utah
A paid session at a commercial park, an afternoon in a neighbor's yard and an injury traced to the trampoline itself each lead to different Utah rules, and so to different deadlines and defendants.
At a commercial trampoline park, the jumper usually paid to enter, so section 57-14-204's charge exception keeps the recreational-use no-duty rule from limiting liability that otherwise exists. Parks often ask jumpers, or parents for children, to sign a participation agreement or release. How such a document affects a claim depends on its wording and who signed it; a release signed by a parent may raise different questions than one signed by an adult jumper.
On a backyard trampoline, the homeowner's responsibility to guests, including visiting children, is a premises-liability question. If the injured person came onto the land for recreation, the recreational-use statute may apply, along with its exceptions for willful or malicious failure to guard or warn and for an owner who charges a person to enter.
When the trampoline, its springs, frame, net or padding is claimed to have failed, the Utah Product Liability Act applies. Section 78B-6-706 requires a civil action under the Act to be brought within two years from the time the person "discovered, or in the exercise of due diligence should have discovered, both the harm and its cause." Section 78B-6-705 adds that an alteration or modification made after sale that "changed the purpose, use, function, design, or intended use" of the product counts as fault under Utah's comparative-negligence statute. If you added or swapped parts on a home trampoline, that history may matter.
A trampoline at a facility run by a city, county, school district or other public body brings in the Governmental Immunity Act of Utah, with its own notice rule, described below.
For someone in this position, the practical stakes are that the wrong label on the setting can mean watching the wrong clock. The questions worth weighing are similar in each case: who owned or ran the place, whether anyone paid to enter, and whether the equipment is still available in the condition it was in that day.
