Hi Royal 30!
When filing for divorce the following procedure is the norm:
You submit form D8,
divorce petition ( 3 copies) together with the necessary fee (£300) and your marriage certificate.
The courts will send you form D9H (notice of issues of the petition), this will tell you when the petition was sent to the respondent (your other half)
The service will will include a form D10 Acknowledgement of Service.
Your other half then has 8 days from the receipt of the petition to acknowledge the service i.e. tell the courts that they have received the Petition.
If your other half ignores service then you should contact the courts and obtain two copies of from D89 (request for bailiff service). You will need to supply a photograph of your other half together with a description.
The bailiff will then personally serve the petition on your other half (this will involve a fee).
When the petition has been served you will be informed.
When you receive Acknowledgement of Service you must fill out form D80 (obtained from the courts) this is a sworn affidavit which just confirms the contents of form D10 as being correct.
When you have completed form D80, take it to your local family court and 'swear it' before an officer of the court (one of the staff behind the counter). The official will ask you to read out an oath stating that the contents of your form D80 are correct. There is no fee involved in this process. You can swear the affidavit in front of an independent solicitor but there will be a fee involved.
At this stage you will have done everything you need to do. A district Judge will check the paperwork and (if it's in order) issue a certificate of entitlement ( form 84A) which will be sent to both parties informing as to when the decree-nisi will be issued.
After a period of 6 weeks and 1 day you can the apply for the final divorce, the decree-absolute.
Any
Consent Order or application for Ancillary Relief should be made after the decree-nisa and before the decree-absolute.
I have tried to give you a brief step by step guide which is in a very simplistic format. Hopefully it goes some way to answering your question.
Best of luck!
