A lot depends on whether homeschooling is something your stb ex also really wants for the kids. If he does, then he and you and a mediator can calculate what he would have to pay to make that possible. If that is more than your stb ex willing to agree to, no judge is going to order support based on homeschooling. Support awards generally are calculated based on the expectation of two working parents. Of course, if you choose to homeschool during the day and work at night (assuming you can work out child care), or something like that, that would be your own decision, but the court order would not include compensation for that. And of course, it's hard to stretch one income to cover one household, let alone two. So, it's basically a matter of what your stb ex is willing and able to pay. Also, the initial award is likely to be lowered by the court in the event that he begins a second family.
