Please help !

I have booked a Flat on a joint name of me and my mother in 2001.
Suddenly in Nov 2007 I got a notice from Tapi Patpedhi, Karvenagar
branch that the flat will be sold off by the bank because there is a
loan taken by my father in law who expired 3 years back.

The reason for the attachment is that they think that the loan taken
by my father in law in 2001 is used to pay initial amount for the falt
in 2001. But when I got married in 2005 how come I would use that
money in 2001 when I did'nt even know them.

The tapi bank have already given 5 dates for hearing and everytime
they just give the next hearing date with no outcome. They are
harrassing my family knowingly to get some money back from me for the
loan which I am not even aware of.

Can anyone help me to see what can be done to punish such careless and
wicked officers and relive me of this harrassment.
