In USA, if you are flying under Part 91 of the Federal Aviation
Regulations (FARs).
Are you required to perform weight and balance checks before every flight?
yes, as PIC you are required to be aware of the w&B and effect of fuel burn
on CG inflight
And if so, are you required to document it?
No
Can the FAA show up on the ramp asking you to show the weight and balance
calculation?
No

Know your rights for "Ramp Checks", Yes, Here is my pilot certificate and
medical, and the aircraft POH is right here, but if you don't mind I'm
running late for an appointment and I need to get this aircraft secured. Is
there a phone number were I can call you and we can continue this
discussion?
