My uncle’s property hasn’t been transferred properly, and someone loaned him money at 5% interest, making him sign all the documents under pressure.

In India, a loan agreement can be challenged if it was obtained under duress or undue influence. The burden of proof rests on the person claiming such circumstances, and a court may declare the agreement voidable. The validity of the property transfer depends on the specific nature of the transaction and whether it was done with free consent.
