Bianca had her own marketing business when she met Edward. Her business was successful, and she had a lot of clients. Edward was hoping to become an author and although he had little money, he believed that his luck would change when his first novel was accepted by a publisher.

Bianca didn't mind that he was not as affluent as her and as their relationship developed, they decided to buy an apartment. They found one with a wonderful view of the river for 250000.

Bianca took out a mortgage for 200000 and contributed a further 48000. Edward contributed 2000 which he had won in a competition. They celebrated their move with a party.

In discussion, Edward said that he believed couples should share everything and that when he had made his riches as an author, he would share them with Bianca. Bianca laughed."A wonderful idea" she said.

Whilst Bianca was out at work, Edward stayed at home writing and looking after the house. As time progressed, he earned a little money from a book of poems he had written. However, ten years after they had bought the apartment, he still had not made his fortune as an author.

Bianca was off ill for a few months and during this time Edward used the proceeds from his book of poems to pay the mortgage.

When Bianca returned to work, she realised she and Edward had grown apart. She wanted a fresh start and decided to relocate her business and sell the apartment.

Could you please help to advise them and explain with relevant authorities, cases.
