I was in Court this morning, but from the information you have provided above, namely that you will be using an Unknown Donor at a Licensed UK Clinic, then, as her Partner, you will be the Legal Father of and Child and, therefore, responsible.
There are some criteria for this, however:
- You need to give your consent and sign the appropriate forms, giving the same, at the Clinic
- The Clinic needs to be Licensed and in the UK
- The Sperm Donor needs to have signed their forms as “Sperm Donor” and not as the Mother’s Partner
Essentially, the Clinic needs to have treated you as a "Couple", throughout, and ensured that all their procedures were followed correctly (and that you were given the full information and advice surrounding Paternity etc).
If all of these criteria are met, then, whether you are a married couple or not, you will be the Legal Father of the Child and have Parental & Financial Responsibility.
It should be noted that you can both, once you have both signed to give Consent, give “Notice” to withdraw your consent/agreement to you being the Legal Father but this must be in writing and signed by the relevant Party, prior to any resulting Child. But my understanding is this must be don’t before implantation.
The only way you could not be held financially responsible is if you were not involved at all with the process or if your Partner went ahead without your knowledge.
I trust this assists and I wish you the best of luck in this next stage of your life together.
