Not in a child support issue only. If your case involves time-sharing and parental responsibility the Court could look at BOTH of your behaviors as possibly being harmful to the child, since the Courts want clean, clear, and civilized communications between the parents for the child's best interests. The child support issue only looks at your and his income and deductions.

If it is solely a child support matter with the Florida Department of Revenue, it will not bear any weight as the hearing will only be based on the child support calculation as my colleagues have advised. If it is a paternity matter and time-sharing (visitation) is involved, then it will be relevant.
If the recording has any information concerning his income or ability to earn income it could be relevant, but by the phrasing of your question this recording has more to do with a time sharing matter and nothing to do with the financial calculations relevant in a cs hearing.
