It is not uncommon for someone to relocate after a divorce (i.e. moving out or away). But if you have children you might want to think twice.
You need to consider the emotional needs of your child(ren), as well as your former spouse’s right to challenge your relocation. Typically, courts only allow a custodial parent to relocate if the move is made in good faith and not meant to inhibit the noncustodial parent’s relationship with their kids.
