Thank you for your question
My name is Clare
I shall do my best to help you but i need some further information first
Which part of the Uk are you in?
When did your mother die?
Was there a Will and if so who are the Executors?
What did your mother leave you?
Have you seen a copy of the will - what does it say?
Are you aware that the site charges more for a phone call?
Do you know if they have obtained Probate?
You can check here
So you can Order a copy of the Will?
Once you have the evidence of what you should receive then then you can write the the executors asking when payment will be made and reminding him that after a year you are entitled to interest on the amount view and that he is personally liable to you for the amount as he has to act properly as the Executor - and you can sue him if he does not
Please ask if you need further details
