Thank you for your question
My name is ***** ***** I am sorry for your loss
I shall do my best to help you but I need some further details first
Who dealt with the funeral arrangements?
Does your father still have mental capacity?
What is the extent of the Assets - an dhow many were in your mother's sole name?
Which of those assets were held in your mother's sole name?
All the joint assets will have passed to your father outside of the Will, which means that it is unlikely that there would be any reason for the Will to go Probate - or indeed be acted upon at all unless it deals with the jewellery
It is possible that a specific question about that may elicit a better response
In terms of the way forward a round table meeting - possibly involving a Mediator - is likely to be a better way forward to air your concerns.
If you remain unhappy after that you may have to consider applying to be appointed as your father's Deputy so that you have control over the matter
Please ask if you need further details
