i guess this isn’t about advice but more so a question about a legal thing

i recently found out who my biological father is after not knowing my whole life. he died in a factory explosion. i’m getting to know my grandmother and she told me last night there are lawsuits against the factory and they don’t pay out for 30 years from the time of the accident (which was in 03). she wants to basically make me beneficiary (is that what it’s called for lawsuits? lol) on some (idk how many). i appreciate that a lot and i’m not asking too many questions bc i don’t want to seem too eager? idk. money was never my intentions

anyway the whole 30 year thing seems weird to me but i know nothing about this sort of thing so i just wanted to get some insight i guess
