The Broker is asking for our original property papers to be handed to buyer for his loan be sanctioned by private bank,is it required or will My property be frauded by this?

I really don't know where to post but I need answer urgently so posting it here.

The broker is saying to provide them our original property papers so that the buyer can get his loan sancioned on it. Help me get a suggestion on it. Should I do it or simply refrain they are giving 1L to take papers and saying you'll only lose your ownership once you get paid all money dealt.

Edit- I'm not giving them my original papers but If they ask for Photocopy should I provide or refrain from providing photocopy too?
