which court has jurisdiction for LA FITNESS?

Give us more information.

Racket ball court # 1.

Whatever state its incorporated in.

to start with, you need to know what County the gym is located in.................just because the name has "LA" in it, does not mean that Los Angeles County is the correct jurisdiction

what matter are you bringing before the court.? it will determine which court you need to apply to

you have to follow the procedures listed on the back of the contract to get out of it. arguments about the contract are via the procedures specified. if it goes to court, it is where the contract says.

otherwise [if, for example, this is a slip and fall case] you sue in the place where the accident or incident happened

it may depend on the issue. hire an attorney to represent you and they'll handle it.
