Dad selling land to fund 80 lakhs for my sister's marriage
I am from cash poor wealth rich family, my dad is a farmer and owns some 20 acres of land that my family depends on. My sister is a doctor; she completed her MBBS from pvt college and MD from govt. My dad fully paid for her MBBS and at that time he sold one acre of land to cover her medical education fees and with the remaining money he built our house.
Now my sister is getting married through an arranged marriage setup to a cardiologist. My dad wants to have a very big wedding even though we cannot really afford it. He wants to sell another piece of land for the wedding because the total expenses are expected to cross 1.4 crore( with around 80 lakh from our side and 60 lakh from groom, ours is more because of more gold).
My future BIL's family is wealthy, so my dad wants to match their spending so people won’t say he arranged a cheap wedding. He says that since dowry isn't in our culture, we can atleast do a grand wedding. I really dislike this idea, selling an asset just to celebrate a two-day event is absurd. We still depend on farming and only a small portion of our remaining land is highly valuable, the rest is not worth as much but my dad is not listening, I am tired of explaining him and he blames me that I am more worried about my inheritance than my sister's wedding. What to do ?
