Retired print worker Mr Paull bought his dream home in St Albans, Hertfordshire, in the early 1990s, the High Court in London heard.
The father-of-four transferred the property, now worth about £650,000, to Bradley eight years ago, his barrister Marc Beaumont said.
Bradley, 52, has now asked his father and his severely disabled partner to leave, saying he “requires the property for his own use”.
Mr Paull is asking Judge Timothy Bowles to undo the transfer and hand him back the house.
Branding his son “workshy”, he told the court: “He knows how to get through life without working Monday to Friday.
“He used to be a different person, a nice man and he is not now. He doesn’t care, it’s just money, money, money.”
Mr Paull said he would never have signed over his home “without a promise” that he and his partner Linda could stay there for life.
When they refused to budge, Mr Paull claimed Bradley said: “You’re a ******* lodger in my house.”
Mr Paull told the judge: “I worked hard all my life while he just sat back and thought, ‘This is a gift dropping into my hands’.
I listened to Bradley and I got stitched up.”
Bradley offered his father £100,000 to leave but that was only “between a sixth and an eighth of the equity” in the mortgage-free property, Mr Beaumont said.
Bradley’s barrister Ewan Paton told last week’s hearing that the property transfer was a straightforward “freely made gift”.
He said of Mr Paull: “While it now suits his purposes to describe himself as a ‘sheep’, he was no such thing in 2010, nor is he now.”
Judge Bowles will give his ruling at a later date.
