No ! Firstly, a property relations agreement can be authorized before a notary , instead of a court, before marriage. However,  if it is only authorized  by a notary , instead of a court, which incorporates it into a judgment, it cannot be enforced . To be enforceable, it has to be authorized by a court, if it has not been before. A property relations agreement between a married but divorcing couple included in a divorce agreement must receive court authorization, and receive  the binding value of a judgment. An agreement regarding child maintenance falls within the jurisdiction of a court, and sometimes the transfer of property to minors also requires court approval, as rights and obligations are involved. Accordingly, an agreement of this kind should be submitted to court for approval. This way it will have the binding legal value of a judgment

A pre-nuptial agreement is only legally binding if duly authorized – this can be done before a notary or a marriage registrar, or at the family court or the rabbinical court.
