If you're living abroad and wish to purchase property in India, you can appoint your mother as your Power of Attorney (POA) to execute the sale deed on your behalf. Your mother can sign the documents and register the property in your name without you needing to be physically present. It's advisable to execute a special POA specifically for the purchase and get it attested by the Indian Embassy or a notary public before sending it to your mother. Seeking legal advice on the property beforehand is also recommended.
