Mark D'Amico and Katie McClure made a decision to help Johnny Bobbitt after he gave them his last $20 (€17.20/£15.40) for petrol when their auto ran empty late one night in Philadelphia.
Mr Bobbitt's lawsuit alleges that they committed fraud by taking a large portion of the donations raised for him on GoFundMe for themselves.
For his part, D'Amico said that they did not give the veteran the whole amount at once because they fear he has a drug problem and that he will not spend the money responsibly.
At Thursday's hearing, Bobbitt's attorney, Chris Fallon, said his client had received only $75,000 of the more than $400,000 donated to the fund, the Burlington County Times said.
He said he feels betrayed, and that he prefers to beg in public than ask the couple for cash.
Earlier this month, he told the Philadelphia Inquirer earlier he was back to living on the streets, and believes the couple spent the remaining funds on themselves.
Katie McClure (R) and Mark D'Amico raised $A555,000 to get homeless Johnny Bobbitt off the streets.
During an appearance Monday on NBC's "Megyn Kelly Today" show, Mr D'Amico told Kelly more than $150,000 left of the donations remains.
"From what I can see, the GoFundMe account raised $402,000 and GoFundMe charged a fee of approximately $30,000", Bobbitt's lawyer Chris Fallon told CNN on August 25.
Johnny Bobbitt received a haircut due to the generosity of Kate McClure, who raised more than $360,000 after Bobbitt helped her on the side of the road. Dow also ordered the couple to transfer the money into an escrow account, which will be controlled by Bobbitt's attorneys. "It was like a joke, they were like my parents, but the joke starts not being amusing", he said.
D'Amico and McClure could not be immediately reached for comment.
The couple had promised their online supporters the money would go to two financial trusts for Mr Bobbitt, as well as a lawyer and a financial adviser to help him manage all the money.
Bobbitt dropped out of rehab in the winter when D'Amico, a carpenter, began working on a new job and was not able to drive him to the center every day, Badway said.
The couple said they let Bobbitt park it on land owned by McClure's family, but the Associated Press reported that in June, D'Amico told him to leave.
They also claim to have paid for a hotel room for him while he waited on the van, an SUV, TV, laptop, two cellphones, a $25,000 (£19,232.50) cash lump sum and GoFundMe's $30,000 (£23,079) fee. McClure and D'Amico also bought Bobbitt a truck, which they drove.
"Giving him all that money, it's never going to happen".
