COLUMBUS, Ohio (WTVN) -- Adopted children born in Ohio from 1964 - 1996 don't currently have legal access to their birth certificates, but a new piece of legislation could change that.

"This will affect one-quarter of a million Ohioans potentially," said Rep. Dorothy Pelanda, a Marysville Republican who spent more than 30 years dealing with adoption law.

She says it's not the first time this measure has been floated at the Ohio Statehouse, but this time it's facing no opposition that she is aware of. Rep. Nickie Antonio, a Lakewood Democrat, is a co-sponsor.

Pelanda doesn't think many of those who were born during that time frame will actually expect to find their birth parents because of the change since the documents are so old.

"Really the importance of this to an adopted child or adopted person is it's more of a historical document than really giving any accurate or current information about where birth parents reside," Pelanda said.

Ohio law forbids an un-married mother from providing information about the father of their child on a birth certificate. That information has to be provided by the father.

The bill also gives parents who put their children up for adoption the option to not be contacted in the future through an online form they would fill out.

"They can also indicate that they want to provide or update medical history," she said.

A companion bill is winding its way through the Ohio Senate.
