My dad had every single account, property, etc. joint with my mother, even though she never contributed a penny. He did this so that when the day came when he passed away, my mom would not have any hassles or problems which happens in cases where it is in one individual’s name only. He started this and carried on this mentality from the day they got married.
I don’t think this has anything to do with being desi or non-desi. This just goes to how you are raised and your mentality.
