IANAL: I regularly see articles about how the passengers who were killed signed various liability waivers and therefore how their families have no case to sue OceanGate and others into oblivion. Liability waivers generally only exclude ordinary negligence, if that. In general, you can't waive your legal rights protecting you from gross negligence or wilful misconduct (definitions may vary -- the UK doesn't have gross negligence as such, but you can't waive the risk of death in most cases). The people who were on the sub were very much wealthy enough (and now are high profile enough) to afford the kinds of legal teams that probably won't worry too much about liability waivers in these kinds of suits. I hope they extract every penny from OceanGate and any related entities.
