Teagan Couper can finally access funds paid out by the Commonwealth Bank for a life insurance policy for her late father, Noel Stevens.

In a now-famous case, Mr Stevens spent his dying days battling the bank, after it refused to pay out a policy when he was diagnosed with terminal pancreatic cancer.

The bank ultimately lost an appeal over the policy in late 2013, but Ms Couper says that when she asked her lawyers about the money, she was told they were still negotiating costs with CBA.

Just last week, she received a call saying the CBA was now acting quickly to finally resolve costs, prompting claims the banks are trying to "clean up" difficult cases ahead of a Senate grilling on Tuesday.
