Do I need to be present for the reading and do I have to sign any documents ,

Depends on whether you are a beneficiary of the will. The "reading" of the will is not a legal necessity. You need to check with your local probate court to see if it has been filed.

And how do you find out if you been left any inheritance of a will that could have been intercepted by fraud

If I am the beneficiary and if there hAS been anything left to me

and how do you find out if you been left any inheritance of a will that could have been intercepted by fraud

Limit your question to only one thread please.

Has a probate case been filed? Check the court file to determine if a will was filed.

If not, and you don't know if there was a will, it will be hard to prove a will, absent a copy or other convincing evidence.

Go to the Court that probates Wills in your area and ask.

At least three threads. One question.
The other threads are here (https://www.askmehelpdesk.com/family-law/how-do-u-go-about-finding-out-if-you-beneficiary-will-if-has-not-been-584678.html) and here (https://www.askmehelpdesk.com/family-law/how-do-find-out-about-will-has-been-read-584675.html).
Merger please.

Now it's 3 threads on this issue.

And counting.

It's also helpful if the same information is posted in both threads.
