Is it permissible for the groom to sign a list of marital assets that includes all contents of the apartment, including what belongs to his father, without his father's knowledge?

The list of furnishings is considered part of the mahr (dowry). What the husband brings is an expedited mahr that the wife owns and permits him to use. What he does not bring is a deferred mahr, due upon death or divorce. There is no objection to considering the list as mahr if it is mentioned in the marriage contract and signed by both spouses. If the father insists on writing down what the husband brought as part of the mahr, there is no objection for the husband to agree without his father's knowledge, as long as the father has transferred ownership of these items to him. However, it is advisable not to disobey the father to avoid disputes. It is better to reach an understanding with him and convince him that this is the prevailing custom.
