FORUM SELECTION CLAUSES ARE NOT BINDING ABSENT A SIGNED WRITTEN CONTRACT. EVEN WITH A CONTRACT, ALMOST NO COURT IN THE US WILL HONOR A FORUM SELECTION CLAUSE BETWEEN A CONSUMER AND A CORPORATION.
Think about it: if forum selection clauses did have legal effect (between consumers and corporations), you wouldn't be able to sue most companies unless you were willing to go to Delaware (where roughly 90% of naitonal US corps are headquartered). The reason we have lawsuits everywhere is precisely b/c you can file anywhere, even despite a forum selection clause.
ONLY BUSINESSES NEED TO WORRY ABOUT FORUM SELECTION CLAUSES.
Choice of law clauses are different.
