Does a HELOC check everyone's credit on the title?

[Michael Cote]

If my uncle and I are both on the deed, and I'm wanting to get a HELOC, will it require his credit score to be decent? He has a bad score at around 540, but mine is around 750. Is there a way to get the HELOC without bringing in his bad credit? What if I wanted to do a cash-out refinance? Will that also depend on his credit since he is on the deed?
