How to safeguard huf property from attachment?

As guarantor you are responsible ,you cannot escape ,to avoid attacment if you have personal income disharge the loan .

The HUF property belong to all the members of the HUF hence you cannot give the HUF property as a collateral security to the borrower in the capacity of a guarantor. 

Have you given this property as collateral security?

if not  then you don't show this property at all but you will be liable as a guarantor if the borrower has defaulted in loan repayment. 

No sir, Collateral security is not given for any property but signed as a guarantor in an individual capacity. 

HUF property can not be considered as individual property of it's any member so it can't be attached .Bank can attaced guarantors individual property only.

Not understood what do you mean.  You have to live with the fact that as guarantor you are liable to pay the loan.  Till such time this loan remainins pending (interest swelling each day) you will not be able to get loan from any bank for any purpose.

Has the Bank initiated the steps for recovery. In the absence of any collateral security, any attachment is possible only on the strength of a decree from the competent court/forum.
