The number of witnesses required for a will varies by jurisdiction. In many places, at least two witnesses are needed to validate a will, ensuring that they are present at the time of signing and can attest to the testator's capacity and intent. Some jurisdictions may have different requirements, so it's essential to check local laws to ensure compliance. Additionally, witnesses should generally not be beneficiaries of the will to avoid potential conflicts of interest.
There is no requirement for witnesses.

You need two witnesses for a will or codicil to a will. However, if the will or codicil is entirely handwritten (holographic will/codicil), no witnesses are needed. Holographic wills are valid in Ontario, Alberta, New Brunswick, Newfoundland, Quebec, Manitoba and Saskatchewan.
In Pennsylvania, a codicil to a legal will requires the signatures of two witnesses. These witnesses must be present at the same time when the testator, the person making the will, signs the codicil. It's important that the witnesses are not beneficiaries of the will to avoid any potential conflicts of interest.
In a court of law, the number of witnesses needed to convict someone varies depending on the case and the evidence presented. Generally, there is no specific number of witnesses required for a conviction. The decision to convict someone is based on the strength of the evidence and whether it proves the guilt of the accused beyond a reasonable doubt.
To be convicted of treason, prosecutors need at least two eye witnesses. With out any witnesses, a person can not be convicted of treason.
There is no requirement for witnesses to a contract.
Two Witnesses.
Many would say they are. Quite a few witnesses say "They are glad they are" because before they became JWs their brain was full of dirty thoughts etc. and their brains needed washing! In reality, it takes a huge amount of study to become a witness and they enter and get baptized of their own free will. Many highly intelligent people are witnesses. So the objective answer is no they are not.
Generally two witnesses are sufficient. However, state laws vary so you need to check the laws of your state.
