Value of words in legal cases

Property was divided 50/50 after my father's death between two brothers. while selling the property one brother paid stamp duty, registration and other expenses. Even though all money matter were settle in Nov 2014 in cash, now one brother is asking 50% of those expenses with interest.

His justification via his lawyer is that I told him verbally that I would pay and he tried to communicate with me many times. I live abroad.

First I did not promise anything because it was all settled in cash. Also there is no record of him contacting via phone, email or registered mail or I signed anything that I owe him.

So my questions.

1. Can he file FIR by just saying I told him verbally

2. Isn't there a statute of limitaion of 3 years even though he is trying to say he tried to contact me.
