I am an additional card holder to my mother's credit card. It has been open since 2000.
The credit limit is $20K.
Will it hurt or help my credit score if I have it removed from my account?
What if I want to increase the credit limit on another existing card. Will it hurt or help or no effect?
Welcome to the forums !
I'd recommend that you take a look at this sticky thread: http://ficoforums.myfico.com/t5/Credit-Cards/Closing-Credit-Cards/td-p/347190
In general, closing a credit card won't hurt your FICO score unless your revolving utilization increases as a result of losing the credit limit.
What is the balance on the $20K limit card ?
