I was under a 1 year contract with a martial arts studio.  I stopped
taking classes to take care of an elderly family member.   With two
months left on my 1 year contract I called the studio to inquire about
getting back into class.  The instructor's admin told me that the
instructor said that I would have to sign a new contract if I wanted
to return to class.  I foolishly signed a new contract, which also
doubled my monthly fees.  When I pointed out a few days later that I should
not have been asked to sign a new contract because there were 2 months
left on the original contract the instructor, through his admin, told
me that they would add two months on to the end of the new contract.

Is this contract that I signed early valid?   Because of my children's
schedules I have not taken a class in more than 10 months.  I would
like to take the instructor to small claims court, arguing that I was
incorrectly forced to sign the second contract, making that 2nd
contract invalid.  Is the 2nd contract valid?

How were you "forced" to sign a second contract? Did they physically
threaten you to sign? If they handed you a contract and you chose to
sign it, then you are bound by it.  You have to agree to the terms and
read the contract before signing it.  If you didn't agree to their
terms, you have to take care of that before you have a signed
contract.

You have a two month extension on your second signing.

That is fair, if you are good you would be signing up until either
Armageddon or you are running the kiddie classes (your fees waived).

The ultimate insult is to have ones fees paid back, in cash.

Somehow I think the guy reckons you have talent.

That or he needs tossers to pad out his pay cheque.

Personally I would forget it
