Matt Johnson doesn’t think he’s asking for much. There’s a school bus stop near his home in Coral Springs, and he wants his 11-year-old son dropped off there on Mondays and Tuesdays, when he has custody.

Johnson, who works at home as a music teacher, said picking up Adam from school would cut into his work hours and his income. Sending Adam to his mother’s would cut back on his time with the boy, spelled out in a binding shared-parenting plan.

Such plans have become increasingly common since Florida’s custody laws were changed in 2008. But in keeping with state guidelines, both the Broward and Palm Beach county school districts only recognize one address for each enrolled child.

“My son has two legal residences,” Adam’s father said. “The district really needs to address its policies and honor the reality that some children live in more than one place.”

At least one school district, Manatee County, which includes Bradenton, has altered its bus transportation policy to accommodate middle and high school students who split their time between two homes in the same school zone.

It’s not known how many South Florida students fit that description. In most cases, local mediators and divorce experts said, separated parents either do not live in the same zone or they work out transportation issues between themselves.

Both Matt Johnson and his estranged wife, Katja, live within the zone for Sawgrass Springs Middle School. A route from the school to Matt Johnson’s neighborhood already exists.

Broward schools spokeswoman Nadine Drew said that doesn’t matter because “the district is not obligated to provide additional transportation.”

Still, Broward was willing to offer a hardship exemption for the Johnsons. It required that an empty seat be available on the bus to the father’s neighborhood and permission from Adam’s mother, the parent at the address on file.

Katja Johnson balked at the idea of her son taking different buses on different days, saying it would introduce another complication in what’s already a difficult transition.

The couple split earlier this year and developed a shared-parenting plan placing their two school-aged sons with their father two days a week and their mother two days a week, and alternating between households on Fridays, Saturdays and Sundays.

Bus transportation is not an issue for the Johnsons’ older son, a Coral Glades High School student who rides to school with friends.

Katja Johnson said it would be in Adam’s best interest to come to her home weeknights until his father was done with work and could pick him up.

Matt Johnson said the parenting plan clearly spells out which days he has custody and criticized the district for not recognizing his authority on those days.

“You do not need a letter from my former wife giving me permission to take care of our mutual child,” he wrote in an e-mail to school transportation officials.

Miami-based parenting coordinator Susan Scholz-Rubin, who mediates divorce conflicts, said she could see why a school district would want to simplify procedures.

“It does create a logistical issue for the school to keep track of a student who gets on one bus to one location on one day and another bus on another day,” she said.

But she agreed that school policies need to adapt to changing custody arrangements.

“Some policies used to make sense when one parent was the primary caregiver and the other was not,” she said. “Shared parenting changes that, and schools have not been good at adapting to that reality.”
