Wrong forum Will sisters credit history be harmed by me if we own a house together?

Hi All,

I own a house with my sister,she is only named on the mortgage but not on the title. I feel that soon enough im going to be in big trouble with my mortgage and there will be a judgement registered against me and i suppose against the house we own together.

If this happens will the fact that she is not on the deeds keep her credit history intact?

Thanks for any replies!
