Garth Brooks talks with a fan during a break in a civil trial at the Rogers County Courthouse in Claremore, Okla. on Thursday, Jan. 19, 2012. Brooks is suing the Integris Canadian Valley Regional Hospital, saying it wouldn't name a women's center for his late mother, Colleen Brooks, after receiving $500,000 from him.

CLAREMORE, Okla. — An accountant for country singer Garth Brooks says she knew of no conditions attached to his $500,000 donation to a hospital in his Oklahoma hometown.

Cheryl Harris testified Friday that Brooks believed Integris (ihn-TEG'-rihs) Canadian Valley Regional Hospital would name a "substantial" section of a building after his late mother, Colleen Brooks. But she says she doesn't know of any strings that may have been attached to the gift.

Brooks is suing the Yukon hospital for the return of the money and punitive damages.

The hospital contends that it didn't give Brooks naming rights in exchange for the money.

Colleen Brooks died of cancer in 1999.
