"Mr. Micawber should apply for his release under the Insolvent Debtors Act, which would set him free"
The Insolvent Debtors’ Act allowed for the discharge of debtors from prison provided they gave up all their property and declared all their liabilities and debts.

It was not until a year before Charles Dickens’ death that the Bankruptcy Act of 1869 finally abolished debtors’ prisons.
