A husband, his wife and their daughter are suing American Savings Bank because they claim the bank lost their safe deposit box, didn’t inform them of the loss and yet continued to charge them rent.

Lawyers for Stephen Fat Chow, Amy S.C. Chow and Catherine S.K. Chow filed the lawsuit in state court Monday.

According to the lawsuit, the Chows started renting a safe deposit box at ASB’s Kona-Ike branch at 1359 Kapiolani Blvd. in 2003.

In 2004, the bank moved the safe deposit boxes to its Kapiolani-Kaheka branch at 1600 Kapiolani Blvd. During the move, the bank lost five safe deposit boxes, including the Chows’, yet failed to tell them, the lawsuit said.

In the meantime, the Chows claim the bank continued to charge them rent for the missing safe deposit box. It wasn’t until sometime in 2009 when Amy Chow went to the Kapiolani-Kaheka branch to get access to the box that the Chows discovered the box was lost. It is still missing, the lawsuit says.

A representative of the bank said it received a copy of the lawsuit yesterday, and would not comment because its lawyers were still reviewing it.
