Sadly there is always room to worry, only because
it all comes down to different judges and how
well they are versed on these issues. Some are
just outdated and resistant to understanding
that nuclear families or biological families
aren't in every child's best interest.
however MA is rumored to be one of the better/more
progressive states and given that this was already
presented in a court, judges tend to side with
their colleagues rather than override them and
so there are more things on your side than against
What's most important is that it's argued
from the perspective of the children's best interest.
That's what matters most.
