Land dispute with unpaid loan

As per your query, let me tell you that if your brother's political influence is something due to which the banks aren't taking appropriate actions against him, then court is the only method available.

In order to stop making unnecessary payments to the bank (i.e. for the part that won't be a part of your share), you need to legally get your share identified. For this, you must approach a good lawyer and file a suit of partition in a civil court that has competent jurisdiction over the matter.

This is crucial because once the inherited property is partitioned, the share received by each coparcener becomes his or her self-acquired property. Henceforth, your own share of the property that you acquired through your father's inherited property will be labelled as your own "Self-Acquired Property", and thus technically you'll be liable to bare any liability for your own part only and not for the entire property.

This will help you, as you'll be no longer requiring to pay bank an excess money for unnecessary means, and since it's legal the bank won't be in any sort of position to question you're decision.

For further input on the same you may go through the following case law -
