A will does not need to be recorded to be valid. But a Will must be probated in order for any of the provisions in the will to be carried out. No one can get anything until the Will is admitted to probate, the deceased settlors estate is settled with all debts and then the court gives the order to distribute the estate as per the terms of the Will. The person appointed as executor in the Will should file a petition to probate the Will and get orders to be appointed executor.
I agree with Mr. Benton. The will is valid if properly executed, not the product of undue influence, and your father had capacity. The failure to lodge the will with the court will not affect its validity. If a handwriting expert deemed the signature your father's, and you cannot prove lack of capacity or undue influence, there is a chance the will is in fact what your father wanted. If you have strong evidence to the contrary, contact an attorney.
