Agreed, but my point is that if the person had known they had been unfaithful then they would deny the tests because the partner who's DNA should be there (whether on clothing or as part of a child) has a likely chance of not being there, if they were unfaithful with one person 50/50 with more than one person then even higher odds. It makes n difference as to how many people there are. The fact that there are any gives the refusal for the test.

The way I see it is that if the suspected party has nothing to hide about infidelity or paternity then they would not refuse the test to be taken. If they agree or disagree surely you have your answer and have saved yourself a considerable amount of money.
