What books (seforim) or lectures (Shiurim) (audio/video recordings) have practical "get" information? — not only how it is written and given but also how the estate (money (ketuba) and children) is divided.
since i see from bellow that in practice we do no use the old laws

Additionally, as Rabbi Feinstein points out, since women today cannot be divorced against their will due to the famous tenth century enactment of Rabbenu Gershom prohibiting such a practice, a divorce today requires the husband to placate his wife with an amount that she would deem sufficient. Therefore, a woman can effectively "negotiate" for an amount greater than the value of the ketubah if her husband wishes to divorce her. Thus, the calculation of the amount of the ketubah only becomes relevant in very limited cases, such as when both parties expressly stipulate that they want the payment amount from the husband to the wife upon divorce to be determined solely based upon a rabbinical court's evaluation of the ketubah. Hence, most couples never expect that the ketubah will actually be used for collection purposes and in fact the majority of Jewish women who have become divorced (or widowed) do not seek to collect their ketubah but rather use other channels to settle their claims. It is, therefore, virtually impossible to ascertain an established custom or practice with respect to the valuation of the ketubah in America.83 Given these questions, it is not surprising, that there is no clear halachic answers relating to the value of the ketubah.
(what will be if the wife wants a divorce and the husband dose not?)
