The appellant argued that the tax exemption for a child was non-modifiable because it was a bargained-for property right. The court looked to the language of the Agreement and held that the tax exemption was indeed modifiable because of the 4 corners doctrine. The agreement about the tax exemption was within the Agreement’s paragraph on child support. The Agreement itself expressly allowed modification for the child support provision. Additionally, the court indicated that allocation of a tax exemption for a child may be modifiable in any circumstance under KRS 403.180(6) which prevents parties from limiting or precluding the modification of issues concerning child support, visitation, and custody.
