NEW YORK, Nov 5 (Reuters) - American Home Mortgage Servicing, Inc, owned by billionaire investor Wilbur Ross, on Thursday said it filed suit against Ohio's attorney general to dispute the state's allegations of unfair practices.

The move comes in anticipation of a lawsuit from the attorney general's office, American Home Mortgage said in a statement.

"Rather than wait to be named as a defendant in a suit that AHMSI considers to be rash and without merit, we elected to petition an Ohio state court for a declaration that AHMSI's servicing practices are fully compliant with Ohio law," the company said in the statement.
