Hello a family law colleague has just informed me that this is not a formal adoption situation from a family law point of view.
From an employment law point of view a person is only entitled to paid leave in respect of their own child or where a formal adoption takes place via a UK or Overseas adoption agency I'm afraid. This means that there is no legal obligation for your employer to give you paid leave and you will not be entitled to the equivalent of statutory maternity pay in respect of any period of leave that you might be given at the discretion of your employer.
It is perhaps worth discussing your situation with your employer as they may, at their discretion, offer you some time off.
I am sorry that this is not the answer that you were hoping for. I would like to wish you the best for the future.
I have seen the information written down myself I just cannot find it again as I have looked at so much written information. I have also spoken to social services who tell me that it is in the legislation but again we cannot find it which is why I paid for your help. Sorry but you did not help at all.
