Our mother died in November 2010 and father died in June 2011 and both died as NRI in Saudi Arabia. We are 2 sons and 3 daughters all residing in Saudi Arabia, except one daughter who lives in India. How can we make a Power of Attorney? We need to make the POA on one of the sons but then on each case he will need to travel to India. Is there any other way that we can entrust an agent to do things on our behalf and specific concent but not act on his own?
