Once you receive a copy of the acknowledgement you can then apply for a Decree Nisi.
To do so you need to complete 2 forms being:
(i) D84 - link below.
(ii) statement in support - link below.
You will need to use statement D80A - as this relates to adultery.
On the top of the 3rd page of the statement it refers to identifying your husbands signature on the acknowledgement. You need to write 'A' on the top of a copy of the acknowledgement and place it as a 4th page to your statement as an exhibit.
You will the need to scan the D84 and statement including the copy of the acknowledgement with 'A' written on the top of it.
Then you can email the documents to:
Please make sure that in the subject matter your write 'Decree Nisi Application' and the case number.
You should then receive a Decree Nisi date from the Court in due course.
6 weeks and 1 day following the Decree Nisi date you can apply for your Decree Absolute. You can email the application form being a D36 - link below.
Whereas your application for Decree Nisi will take a number of weeks to be processed the application for your Decree Absolute will just take a few days.
I hope this helps and all goes well.
