A woman who abandoned her three children over 30 years ago is suing each of them for $750 a month in financial support in British Columbia, Canada.

Shirley Anderson, 73, has been trying to sue her son, Ken Anderson, 47, for 11 years under British Columbia’s Family Relations Act, reported the Canadian Broadcasting Corporation (CBC). That law holds adult children responsible for legally supporting parents “dependent on a child because of age, illness, infirmity or economic circumstances.”

Shirley Anderson wants $750 a month from each of her three children after leaving when Ken Anderson was 15 years old.

Ken Anderson, a married truck driver with two children, told CBC News his mother left when his parents and younger brother moved from the town of Osoyoos, bordering Washington state, to the region around the Kootenay River, nine hours away. The CBC reported he stayed with other families and quit school to work.

“We don’t have a relationship. I haven’t talked to her in years and years and years,” he told CBC News. “She’s just out to make our life miserable.”

On Monday, Ken Anderson’s lawyer asked a judge to throw out the case because his estranged mother reportedly didn’t submit financial documents ordered by the court.

The British Columbia Supreme Court judge reserved his decision, CBC reported.

“I don’t know how anybody could go after their kids,” Anderson told CBC News. “First of all the law is brutal that they can allow this to happen. Hopefully they’ll change the law.”

The British Columbia Law Institute recommended repealing the section of the law in a 2007 report, CBC reported.
