I am doing executor for my first cousins extate .I've discovered that all of her money is in a joint account with a neighbour who is not related. The neighbour drove her to collect the pension etc. My cousin who was single and rented out rooms over the years never declared TAX. The fact that he she had a lot of money saved in a joint account indicated to the tax people that she had a good earnings from her property.The joint account holder is demanding that she be free to cash in all of the joint account now. Can I ask that this account be kept open until such time as my cousins tax liability are met. Can I request that the first call for the tax be from this joint account.
