Is the ruling of the Sharia court valid in not obliging the deceased's children and his wife to pay their father's debt, despite the deceased's mother testifying that her son received the amount?

The judge is more knowledgeable about the intricacies of the case, and judicial rulings cannot be commented upon. However, an acknowledgment (or confession) is only binding on the one who makes it and does not extend to other heirs who deny it. Jurists have differed on this issue: some say that the one who acknowledges is bound by the debt to the extent of his inheritance, while others say that he is bound by the entire debt or by his entire inheritance.
