If you could give me a little more information, I hope I will be able to help you.
I look forward to hearing from you.
Hi, I'm afraid the simple answer is that a Will only covers those assets owned by the deceased at the date of her death. Hence, if the property was sold during your Mother's lifetime, it does NOT form part of her Estate. I can't of course say what was done during your Mother's lifetime, but she would have had to have consented for the sale monies to be used by your siblings, and therefore you have no claim on these monies.
I am sorry this is not the answer you were looking for.
