Property document correction

Hi, I have a property document that needs correction. In the whereabouts of the property, we usually have details of North, South, east , west. Correction here is, instead of west, it was incorrectly mentioned 'north'. So now there are two North in the document. I traced the seller but he is very sick to perform this correction. I tried all ways already. So option of bringing the seller is closed. Is there any legal option through court to do this rectification. And is it costly and time taking?
