It's been 2years since we married and have a 6months old daughter. My manipulative MIL made me give her my 11 sovereign Haram and another 8 sovereign Haram to just wear for the occasion. When i asked them back, i was shocked to know that they have pledged my jewels without my notice or even my husband's. Just a week before my function they just returned one haram. They have been holding this for about 1&half year. And when asked about why did they do this, my FIL said that whatever the DIL brings in to their house that belongs to them and they have every right to pledge or do whatever they want and created a big fight and my husband and FIL came to hit my father when he questioned about their statement.My father gave 16L cheque and they wanted to be in FIL name. This was given to buy 10L car and 6L to buy electronic appliances.They had no intention to buy car And inspite of giving 6L, i myself had bought appliances worth 50K and they possess it now.Will I be able to claim back 16L.
