Your guarantor would need to fully understand their role as guarantor. To make sure that every guarantor understands their role, we explain this to them over the phone before paying out any loan.
They would need to be able to have this conversation with us, and be able to discuss their finances with us, in English.
If the person you've chosen to be your guarantor can't have this conversation with us without the use of a translator, then we can't be sure that they will completely understand the responsibilities of being a guarantor, and so we wouldn't be able to accept them.
