Thank you for your question
My name is Clare
I shall do my best to help you but I need some further information first
Could you explain a little more about the position please
To an extent this depends on when people became aware of the existence of the illegitimate child - was it known in 1986?
When did you discover your identity?
How many other children did he have?
Was there actually a Will or not (I will answer both your questions but it would help to know which is the actual position)
And the Will?
And which part of the UK did the deceased live in
Which part of the UK - there are very different legal jurisdictions involved
You can obtain a copy of the Will here
If the Will simply says "between my children" then you were entitled to a share
If it said "between my children xxxx and xxx " you were not.
If there was no Will and the Intestacy Rules apply then assuming he was not married at the time of his death you were entitled to a third of the Estate.
There is no limitation of claiming funds to which you were absolutely entitled, and since your parentage was public knowledge at the time of death then the Executor of Administrator was under a duty to distribute the funds correctly and you can sue them personally if they have not done so.
I hope that this is of assistance - please ask if you need further details
