Hundreds of gay and lesbian couples have applied for Wisconsin's domestic partnership registry in its first week.

Department of Health Services officials say a new survey shows 440 gay couples registering for the new benefits, Madison's ABC affiliate WKOW reported Monday.

Fifty-eight out of 72 counties responded to the agency's request for the number of applicants. Dane County lead with 115 couples, followed by Milwaukee County with 52.

Wisconsin's domestic partnership registry grants gay and lesbian couples about 43 rights. Most deal with hospital visitation rights and estate planning.

Opponents have asked the Wisconsin Supreme Court to invalidate the registry. They say it violates the state's voter-approved ban on gay marriage.
