Adding fiance to your credit card account might boost his FICO score, but be careful

Dear Liz: My fiance and I are trying to secure financing for our first home, but his credit scores are just below the mark. I was thinking of adding his name to my credit card account so that my available credit line shows up on his report. Would this boost his scores at all? Is there any danger of it lowering his scores?

Answer: If you have a good history with this account -- you always pay on time and you're not carrying a large balance -- adding him as an authorized user may help his scores.
