When you apply for a credit card, the application that you sign is also a legally binding contract laying out all the terms

between you and the bank, such as the interest rate and how its calculated, the grace period, whether theres an annual fee, etc.

While you have to agree to the terms and sign if you want the credit card and while the lender will certainly hold you to the terms, the lender doesnt feel similarly committed.

Lenders like to constantly amend the terms, effectively changing the deal after it was made. This is one of the few industries where you can be charged more than you originally agreed to pay.

One of the main reasons theyre doing this is because they are constantly checking your credit score, looking for an excuse to raise rates and thus their income.

So, even if you have never been late on any payment to any bank or utility, your credit score can raise as youre approaching your credit limits. Or you could have missed a payment or lost your job. Lenders have any number of excuses for their actions.

Also the lenders count on the customers not reading the little inserts filled with legal jargon they slip in with your bill or mail separately, at least until its too late. Apparently the vast major of card holders never look at these amendments. Theu also hope that most of us are ignorant of our credit card rights.

Not all changes to the credit card agreement are necessarily harmful to you, although you'll rarely find one being done in your interest. Most of them change minor terms of the agreement.

But they can contain nasty suprises as well.

The problem the lender has is that the original agreement is a binding contract that the lender cant change unilaterally. They have to give you an out. Thats why it pays to pay attention and know your credit card rights.

I once had a credit card account with the stated interest rate of 13.5%. I was financially strapped and was using more and more of my available debt. I had never missed a payment or was late to anybody for at least 10 years.

However, not paying much mind to my statements, I did not know the bank sent me a notice that it would raise my rate if I used the card past a certain date. I did and I found myself facing an interest rate of 24%. Calling the bank and complaining and threatening to take my business elsewhere had no effect.

After that I started to pay more attention to those little slips of paper. Twice more different lenders tried to do the same thing. But I followed the directions on the amendments to the credit agreement and wrote the bank within the time frame given, telling them to cancel my account. You must no longer use the card afterward. If you do, youve accepted the new terms in spite of your letter and youre stuck with them.

If you have any automatic charges being made to the card, including things like credit insurance that the lender itself

sells you, make sure they are cancelled in writing before the cutoff date. One little automatic charge will also constitute an acceptance of the changes in the credit terms. The bottom line is that the lender will consider any little slip in its favor and hit you with the higher rate.

As long as you continue to pay your bill under the terms of the original agreement, the bank can do nothing about it. You can pay off the bill at whatever pace you see fit, as long as you make the minimum payment.

I consider the lenders actions as akin to kicking you while youre down. Most people wouldnt be using up their available credit unless they were already struggling. My credit card payments went up $46 per month on that card. I saved thousands by refusing to go along with other proposed increases.

The issuer of one of my cards that has carried a zero balance for several years has been periodically raising the rate to where it is about 25%.

Know your credit card rights and fight back. If youve havent gone completely over the edge yet, you might find a lender willing to work with you.
