What is the name of your state? SC
I disputed some of my collection accounts since most belong to my ex-wife a couple of weeks ago. My question is do i need to send a follow up debt validation letter to these companies? And if so, Do i have to send the certified mail? (which is very costly!!!)

If they don't respond to the first validation letter, can I just send the letter to the credit reporting agency? Sorry one more question, Is it even nessicary to send the first validation of debt letter certified mail?
