I am aware that any transfers of assets made within 3 years of death may be bought back into consideration as notional estate. If someone though sells their home, then buys a new property, placing the property into joint tenant ownership, can this property be bought back in - wholly or partly - to the estate value as notional? I am aware joint tenant ownership does not require probate, however not sure how the purchase would stand and if contesting a will how to go about including a joint property into the assets of the estate.
