Please do not underestimate the court. What you say will have relevance and be taken into consideration.
He will certainly have to produce medical records as evidence of his admission to hospital in light of the history.
The court will only order unsupervised contact when they are such there is no risk and as I say it will only then be built up gradually to overnight.
It is a credit to you that you are accepting of his mother.
Sadly the court comes across many resident parents who do not want the other parent to have contact making many excuses.
Therefore keep your concerns brief, factual and to the point. Sometimes parents make so many complaints they lose the effect of the stronger points.
For you it is simply:
- Little interaction and care of your daughter,
- Concerns over his health as evidenced by hospital admission, and
- Failure to complete 10 week course.
There of course maybe more but as I say just lead with relevant points to avoid losing the impact of the above concerns.
