My 19 year old step daughter moved out of our house in Feb of last year to move in with her boyfriend...The relationship did not work out after 1 month and she ended up moving in with friends and living at her sority house as well because she did not want to live in her mothers house either (until she had her new house built).
Her mother (his ex) built a new house down the street from us and is now claiming that she lives with her. We can see that she is never there during the day and her car is not there at 5am when I leave for work... we know for a fact that she is living with her new boyfriend but has worked out a deal with her mother so they can split the child support payments.
We went to court and the problem is, even though we can prove that she does not spend the majority of her time at her mothers home, we cannot prove that she is not living there if both her mother and her say otherwise.
What can we do to PROVE that she is not living there? We live in Ny State
