Are there provisions for a written statement, given in front of witnesses, being considered as a will by the government? My father with 2 witnesses wrote such kind of a letter mentioning my brother as the sole beneficiary of his will. Can this document be considered a will in the court? Note that there was also one medical practitioner present, at the time when this letter was written, to certify the well being of my father's health.
A will can be in any form and the letter executed by your father will have to be proved in a court of competent jursdiction whilst seeking Probate of the same.
