My question involves business law in the state of: Colorado
I own two separate LLCs, one formed in 2004 and the other in 2007. Each has different name, address and EIN. I opened up a credit line with a supplier in 2005 with a personal guarantee. Never used much. In early 2008 i opened what I thought was another different credit line at the same supplier with the new company. This line was used lots. Now business is slow and I owe money on 2008 credit line with new company. after reviewing the account I discovered that the supplier did not open a new separate credit line for new company but changed name on the old credit line. Which credit contract is good? The twist is I declared personal chapter 7 in late 2008 which should have discharged the personal guarantee for at least the older credit line and possibly the new line as well. I can't find information on this situation.
