My mother has gifted a significant amount of money from the sale of her property, equally to myself and my two sisters. My two sisters have taken up their gifts but I have opted to leave my portion in my mothers account as it would significantly impact the age pension. If I had not taken up my portion prior to my mother passing can the discrepancy be sorted out by the executors/beneficiaries - the estate will be left equally to the 3 children. Would a letter of agreement signed by all of us be sufficient to vary the distribution of the estate or would there be legal restrictions which would mean that things would have to be sorted out after distribution. Hope this make sense. Any advice would be appreciated.
