What witness statement, in what case?
yes
Yes, if you are called upon to provide a witness statement to an attorney, it is important to accurately and truthfully record your account of events, details, or observations related to the case at hand. This statement helps the attorney understand your perspective and can be used as evidence in legal proceedings. Being concise, clear, and detailed in your statement is key to effectively aiding your attorney in building a case or presenting your side of the story.
On witness's statement to investigators - no. On the usability and admissability of them in court - yes.
A person who gives a statement is called a witness.
Most probably the same as you'd write in the funeral guestbook of a person who wasn't a Jehovah's Witness.
I think you mean written statement. What you are asking about write statement you are confusing with written statement, the same with write in statement. A written statement is simply putting your words, or your version of events in writing.
Absolutely.
Hearsay
This is hearsay, which is a secondary source of information that is not allowed.
To obtain a notarized sworn statement, you need to write out the statement you want to make, sign it in front of a notary public, and have the notary public witness your signature and stamp the document with their official seal. You can find a notary public at banks, law offices, or government offices.
Generally, written testimony is unavailing if the other side does not have a chance to cross-examine the witness. It doesn't hurt to try, though, if that's the best you can do. A notarized statement might be very helpful to establish damages if the other side defaults (does not show up) and you can be awarded whatever damages you can prove.
