Is there any sin on him if he takes out a loan for someone else and he does not pay it off?
Question

                If a person takes out a loan in my name but the debt is not mine, rather it is for him, is there any sin on me if he does not pay it off?.
Praise be to Allah.What we 
    understand from your question is that you want to take out a loan in your 
    name, so that someone else may benefit from it, and this person may or may 
    not pay it off. In that case you will be expected, according to sharee’ah, 
    to pay off the loan because apparently you took it for yourself, and the 
    loan was given on that basis. 
If you know 
    that the borrower will never pay it off, then you should not help him to get 
    that loan, because by doing that he is a wrongdoer and aggressor who is 
    exposing himself to the punishment mentioned in the words of the Prophet 
     (peace and blessings of Allaah be upon him): “Whoever takes people’s 
    wealth intending to pay it back, Allaah will enable him to pay it back, and 
    whoever takes it intending to destroy it, Allaah will destroy him.” Narrated 
    by al-Bukhaari (2387). 
But if you 
    intend to pay it off for him if he refuses to pay it off, then there is 
    nothing wrong with that, and you will have done him a favour with this 
    money.  
To sum up: 
    So long as the loan is in your name, then according to sharee’ah you are 
    responsible for paying it off. 
And Allaah 
    knows best.
