Нина Романченко после трагической смерти обоих родителей проживала в полученном на наследство дома вместе с тетей, которая была назначена её опекуном. Когда Нине исполнилось 16 лет, она, получив разрешение исполкома в снижении брачного возраста, вышла замуж за 20-летнего Проханова, который проживал в другом городе. В связи с отъездом к мужу Нина решила продать дом и нашла покупателя. Однако в нотариальной конторе, несмотря на предъявление свидетельства о браке, договор купли-продажи здания не был засвидетельствован на том основании, что Нина - несовершеннолетняя, а разрешения опекуна на продажу дома нет. Нина обжаловала действия нотариуса в суде.

Какое решение должен принять суд?
